Yesterday I went to a small puzzle meeting and received Charpentiers Illusion as a present. A very interesting trick! Thank you, Christoph! Bernhard had some new interesting TICs for me: Threaded Cube and Ka'apuni. This morning a package with Eric Fuller's latest creations arrived, containing the Liberal Cube, NOS1 Compressed, and NOS3 Round Trip. These NOS ("New Old-School") burrs are fascinating coordinate-motion puzzles and hard to build as well as to solve.

Just before Christmas the very nice Karakuri Christmas Presents 2015 arrived. X-mas present 1, X-mas present 2, X-mas present 3, X-mas present 4, X-mas present 5, and X-mas present 6. I did my usual guess about the craftsmen, please see the details pages. For two of them I already know the name, and the Bean Bag Drawer 2 seems to be an extension of my favourite present for 2013 with nearly the same name. These boxes look very nice and I am expecting different mechanisms with little surprises.

A heavy package with some nice Indian style trick locks from Canada arrived, from Puzzlemaster: Heart Shape Brass Puzzle Lock has some new tricks I have not seen in a lock before and it will take some time until you even find the first key hole, Brass Square Puzzle Lock has a simple, but new mechanism, and Brass Figure Puzzle Lock Lion is simple but beautiful trick lock.

My latest auction wins: 4 Direction Drawers is an interesting interaction of drawers, the The Arabi Gun is a sequential discovery puzzle design dating back to 1890s and before! The US Cube is a boxed burr, in which you have a clear view from the outside. The Heart Spin Box I do not know much about yet. Some of these puzzles I have wanted for some time.

Some of the latest puzzles built by Eric Fuller: Cubloc looks very interesting and is the bigger brother of the beautiful Cubloc S. The mysterious Packira extends the four sticks in a box with 6 orthogonal sticks, and the Tulip has a 7th piece inside, and has a different level without that piece.

After the wood puzzle overload recently, today a package arrived from Cubezz: The Curvy Chop is basically a Curvy Copter chopped in half (and finished by closing the cut). I have a spare Curvy Copter lying around here to build this puzzle, but never got around. Now I had the cance to buy the finished puzzle. It came together with two others, one new, one older: Mastermorphix and Football Magic Cube
Of course, I am continueing with my "big puzzle project" and have made considerable progress on GAME CRAZE. Wait for an update soon!

GameCraze Today a huge package arrived after a fast journey from the USA. In it was one puzzle consisting of five boxes created by the creative Tracy Clemons. Very well crafted, beautiful and much more. A fantastic puzzle to be explored. Of course, there is the usual puzzle page (Game Craze), but I also set up a special feature page with an initial description, where I will add more and more after I have played with the puzzle and discovered everyting. Please click on the following link to the Game Craze Feature Page.

Today a nice puzzle event: GPP at Bernhard's place. He had some interesting puzzles to offer, including some prototypes. Some of them are new interlocking cubes, including some by Ken with half unit pieces and complicated rotations. Today's haul are: Konstrukt A, 2 Halves Cube, 2 Halves Pack, Popp, Tronc Commun 3, Meandros Cube, and Gravity. Thanks, Bernhard, for the puzzles and the nice event!

Today some nice new puzzles from the Czech Republik arrived: Serflex, Cross Imprisioned, and Vauban H 5. The last puzzle is one from the Burr Zoo: Dragon's Cave. It has a little dragon inside trying to get out. When Stephan showed me the Burr-Tools file some 1.5 years ago, we were discussing how to implement the puzzle so that you can look in. I like the solution they found with the round holes in top and bottom of the frame. Let's see how this impacts the solution, if at all.

Yesterday I went to the Dutch Cube Day to meet many puzzle friends, see some interesting new puzzles and of course to buy some puzzles. As first puzzle, I received this years DCD present, the Red, White and Blue, nicely 3D printed with country colours and name of the event. It started with catching up with some IPP puzzles, first from Robrecht: 50 Cent Labyrinth and 8 Stars Labyrinth. Then some new and old for n-ary puzzle group and compendium: Bin Laden Too and Elephant SpinOut.
Alfons had a huge selection of his nice wooden puzzles for sale, so I could not resist, of course! First, in the 18 pieces burrs group there is Hell (with 12 frame pieces, similar to Stephan's Fortuna or his Burrison), Mountain (designed by Dan, and with an 18 piece and 6 piece burr combined in one puzzle), and Knudde (which uses the unusual shape to hide some more pieces inside). Belopo is something similar for a six piece burr: with additional clamp pieces (similar to Stephan's Plankton). Tarpan is similar to Skunk I had so much fun with recently, and maybe that is why Alfons presented me this 12 piece burr with 3 frame pieces. Vera is quite new, but not as unconventional as the following ones: Box of 12, Rampart 2, and Jail Bars 2 are all some burr sticks within a cage so trapped that it is hard to guess how to get them out. Doender has similar piece configuration like the Rampart 2, but between two stacks of boards.
To continue with some more IPP35 exchange puzzles, I got myself some: Quadrant 1, Forgotten Piece, Smiley Burr, TrickLock 2015, and Pole Dancer. In a recent auction, Steve offered also the Twiddle Dum Helical Burr and Twiddle Dee Helical Burr. Now I have all 6 of Derek's twisted burrs and have to be careful not to get my brain twisted during solving. Ella Propella is also about twisting (or rather turning): You have to unlock the propeller so that it turns freely. The next three puzzles were some I wanted to add to my collection for some time: Secret Box No 2, Dino Star, and Leesho. It seems that Hungary (represented by Olivér) is still a good source for vintage Twisty puzzles. One of the interesting talks was by George Miller about his Cubigami puzzle and the countless nets forming shapes created from cubes, kindly handing out a Cubigami Net 4x1x1 for demonstration.
The last puzzle arrived this morning and is the latest from the Naked Secret Box series, the Naked Secret Box Purple. Beautiful and an interesting mechanism!
A big thank you to all of you who offered me these nice puzzles, ensuring that I will have some puzzle fun in the next time and will be extremely puzzled by some of them!
Note:In this post, I have just named the reference puzzles I already have, not linked to them, to avoid confusion which are new and which are old.

Today a huge package arrived from Brian Menold, and after opening I saw the reason: The Proxima Centrauri is a big frame of two pieces with some four smaller pieces in the corners. Looks beautiful and impressive! The other puzzles also look beautiful, but are of a more normal size: Altair, Quadrox, Stairs Cube, and Four Mirror One. Alltogether some stack of nice puzzles interesting both in solution level as well as the woods used.

Today a package from Stephan with some of his latest creations. The l'Unifolié looks beautiful and excellently crafted, must have been a lot of work! It was Stephan's entry into the IPP 35 Design Competition. It has the same basic principle as the Caught Heart, the Rammelkast, and the Hazelgrove-Box, but an additional stick that has to be manipulated from the outside while solving the box. The other beautiful puzzle is one from the 18 pieces burrs group: Burrner. This beautiful burr has extensions on the sides of the 6 middle pieces, which makes it a very interesting puzzle with a high level. Maybe not the highest level for the first piece, but certainly impressive for the first 5 pieces combined.

Today a small parcel with many puzzles was waiting for me to pick up: Diamond Entanglement, Key Shaped Puzzle Lock, Secret Box No 4, Mini Secret Puzzle Box, Bird in the Nest, Euro-Falle 3, and Euro-Falle 4. Some are IPP puzzles from IPP35, and then there are some nice others.

Maybe you remember the DITWIBIN by Namick Salakhov? A nice puzzle in the n-ary puzzle group and therefore also in the compendium. That puzzle has a clever mechanism and is fun to play with, and is a simpler relative of what arrived today: The MixTer-MaxTer. It was an entry in this years IPP Design Competition, and I think it is a brilliant design! You "just" have to guide the little red sliders from the outer disk with two slots and collect them in the other outer disc with many slots. My discovery of that puzzle went through three main stages:
  1. Try to move the discs (which are moving simultaneously!) and get some of the sliders moved to other discs. Feeling confused.
  2. After a while, my hands seem to do some moves automatically and I am beginning to see a pattern. Could this be a n-ary puzzle with base 7 (like 7 discs)?
  3. Now I have understood where each of the sliders can go, and each can only go to three discs! The puzzle is a ternary puzzle in disguise, including a hidden locking mechanism interacting with the little red sliders. Very clever design!
The name seems to be a technical term referring to the ternary nature of the puzzle, but then it is also a Scottish word describing my initial experiences with the puzzle very well — please have a look into a dictionary if in doubt! Excellent puzzle, thank you, Namick!

I am not good at tray packing puzzles and rarely collect them, but today I got myself one. Very difficult and multiple challenges by Wiliam Waite. However, it is also a puzzle box! The latest of the famous Stickman Puzzleboxes by Robert Yarger. You may have guessed already — it is an Edelweiss Puzzlebox, and it's a real beauty, isn't it?

Earlier this year I had some conversations on variants of the Double Slideways Burr, also with the Designer Ray Stanton. His IPP35 Exchange puzzle is base on the simpler Slideways. It is the Slideways Cube, which arrived today. When looking at it you may not spot any similarity with the other puzzles mentioned, but it is there, internally. Just that getting an idea how to disassemble this one is much harder than for the others, also due to the nice fit concealing any cuts or gaps that there might be. Thank you for the nice puzzle, Ray!

Recently Johan Heyns asked who would be interested in one of his designs, built by himself. Of course I ordered one and today I received a beautiful puzzle: Canuck. It is the second version and the main difference is that little checkerboard pattern on the sides, a very nice looking feature, I think! The puzzle did not come alone. If you have a close look onto the picture, you will see the stand the puzzle is resting on, which came neatly packed in pieces and was an assembly puzzle by itself! Thank you Johan, for building this nice puzzle for me!

After Wil's recent newsletter I could not resist any more and got myself a new Ying Yang 69. It is nice heavy metal quality, as usual. I played with the prototype at IPP over a year ago already, and the puzzle looked very interesting back then already.

Today my puzzle friend Dirk visited me and we had a little post-IPP puzzle party. Beside many nice puzzles he brought his IPP Exchange puzzle with him, A-Mazing Blocks, a fascinating extension of sliding pieces puzzle with a maze, multi-challenge, of course! The second new puzzle is the Racktangle, from the IPP Design Competition, and has been pubished in Goh Pit Khiam's article "The Design of N-ary Mechanical Puzzles", which can be found in my compendium. The puzzle has a new entry in this compenium and n-ary puzzle group page. After the Power Tower it is the second puzzle offering some additional parts allowing to set up an n-ary sequence by choosing mixed-base plates (of base 2 and 3) and with variable stage count up to 4. Many different challenges in one puzzle. As you can see in the picture, it is nicely made by Tom, and the second of this kind in two days!

Today I received a special puzzle, which was designed for me by Christoph Lohe. In the correct German spelling, my name is spelled: Götz. Now take a look at the pictures of the puzzle to the left, you will recognize the scheme! The GÖTZ puzzle is built around my name, and luckily there are only 4 letters in it. Thanks to Chris and also to Claus who supported me with 3D-printing this nice puzzle! And beside bearing my name, it is also a nice and nontrivial interlocking puzzle!
The second package arrived later the day, with my wins from a recent auction: Open-Side Coin Bank, Dovetail Burr Puzzle, and Sandfield Joint Puzzle. All of them are beautifully crafted and more on the traditional side. Some very interesting puzzles which will take their time to solve for sure!

Today something very unusual happened to me: two packages from Japan with brand new puzzles! The first one contained an ATM. Unfortunately, it does not come with any money in it, so I had to pay the taxes at customs myself. Maybe the officers were also confused by the name of the puzzle: Please Pay the Fee. The invoice showed just the name of the puzzle and the total. The puzzle is beautifully made, and even has a little view screen that tells you if you have already paid your fee and you will receive your savings. A great piece of art, too!
The second package contained a whole series of old puzzle designs, re-released as a brand new series, and only available in Japan at the moment. The puzzles are looking beautiful and they are new version of a complete Marcel Gillen Chess set, in particular: King, Queen, Bishop, Knight, Rook, and Pawn.

Because of the current strike puzzle deliveries are unusual now: taking longer, finally showing up on Sunday! From Austria Stephan sent me one of his latest creations: Fortuna. This nice 18 pieces burr has some extra 12 cage pieces, and is two puzzles in one. With and without cage pieces there is a unique solution, but of different level. A similar concept but with a solid frame was designed earlier on: Boards and Sticks with Frame. I had some trouble putting it into the 18 pieces burrs group, because in one assembly it has more pieces than 18, and it has two levels. I put it to the level 10 entry, which lists some other unusual 18 piece burrs already — only unusual ones, to be precise!

The second package is from the U.S. and it is fitting that it contains item 1776 in my collection, but then it should have arrived yesterday already! Some of the latest works by Eric Fuller, designed by two U.S. designers well known for years (or even decades): Helix the Burr, Think outside the box, and Inner Cube. After struggling with the half notches in the Visible Burr the Helix the Burr now offers third notches!

A nice and well made wooden puzzle lock: Wooden Lock Puzzle. It seems to have multiple steps and is a design I have never seen before. It comes with a nail, but I am not sure what that is good for. I have yet to solve the lock and I am sure I will find out. So far I have found some unexpected features.

From CU-Japan from the UK a box with two boxes inside, and inside them two boxes. Sounds familiar? The package contained the two Naked Secret Boxes I did not have before: Naked Secret Box Green, Naked Secret Box Orange. Like the blue and red one they are very nice puzzles with a very interesting look. Who would have the idea of making puzzle boxes transparent? Some of the techniques remind me of the Black Box (see below), but that box hides all internals. These "Naked" secret boxes let you see every detail allowing a thorough analysis when solving.

Diniar is a well known desginer of sliding pieces puzzles. From him I received one of his newest puzzles: the nice My Tower of Hanoi. It looks like two Tower of Hanoi combined, or a bit like a Panex, but that is where the similarity ends. It is a nice and well-made sliding pieces puzzle with many challenges, of which I have solved the first one already.

From the Netherlands an interesting and heavy box. Containing an interesting and heavy box. Containing an interesting and heavy box ... That one is Wil Strijbos' latest creation, the mysterious Butterfly Lock Box. My first impression is that it satisfies both meanings of the German word "schwer": heavy and difficult. A beautiful and very well crafted puzzle and long awaited. I am very curious to solve this one and wonder how long it will take!

A package from Hong Kong with some nice new Twisties. Actually some of these models have been to visit to my place before, and that cleared my doubt and I ordered two: Curvy Dino I have solved within minutes and it is easy, but interesting looking. The Dreidel 3x3x3 seems to be harder to solve and demonstrates some "parity" issues. The puzzle looks fascinating, with those corners turning independently!
Added on 2015-06-01
First package of the month contained my wins from the recent Haubrich auction: The mysterious The Black Box — mysterious not only from the black look. Is it a box, or is it a burr? Is it both? The nice Wun-Wa-Sure, as it occurred in the IPP21 design competition.

Another puzzle surprise from Switzerland, a new variant of Double Slideways Burr: The Double Slideways Burr+D is a variant of the Double Slideways Burr TSP, with some triangular prisms added to the three identical pairs of pieces. That is also what the "+D" stands for, it's for the German "Dreiecksprisma". It is fascinating how many variants can come out of a puzzle during optimization. I find this version the hardest to assemble, probably because it does not have much space left and has obstructions added. It works in the usual three-axis coordinate motion move. Thanks for sharing this with me!

Another puzzle surprise from Switzerland, a new variant of Double Slideways Burr / Double Slideways Burr TSP-: The Double Slideways Burr TSP-+2W is like the TSP variant, and adds 2 new cubies — can you spot them? This removes the remaining internal holes and now the two halves can only be assembled in two directions, not in three like for the TSP-. The new pieces do not have any angled cuts, but now these pieces are non-notchable. An interesting idea to follow-up would be to include the two extra cubies as separate pieces. Thank you, Peider!

From Alfons I received some very beautiful and special interlocking/burr puzzles. In the category of 18 pieces burrs: Alien (which looks like a traditional 18 pieces burr at first sight, but is a much more interesting 26 piece burr at a closer look), and a difficult and true category member: Armilla. The puzzle Skunk looks like an interesting 18 pieces burr with some clamp pieces between, adding up to 21 pieces, and also with level 21. A new and visually fascinating concept are the interlocking puzzles with stacked frames, which look like they can telescope out of the puzzle during the solution. It will be very interesting how to see how Pulsar and Pulsar 2 will work during the solution. The Kameleon caged was interesting to me at first sight, because it is based on a very similar puzzle, without cage, and a difficult one: Kameleon. The base of the fascinating Dirty Dozen Caged is the Dirty Dozen (the first puzzle Alfons built for me). So what does this new version consist of? Let's analyze the name: dozen = 12 core pieces, dirty = 4 extra hidden pieces, caged = a cage. This cage is not a fixed frame, but another 12 cage pieces. All this adds up to 28 pieces, 12 of which are identical, yet 26 moves for the first piece!

This weekend Michel and Maarten were visiting me and brought me some nice puzzles for my collection: Keychain Burr 9 pieces (came disassembled for an extra challenge), 3D Labyrinth, and 3x3x3 — thank you! This morning we got up early and went to Wil's place to where he had invited us for his yearly puzzle party. A great event, where I met many old and new friends, and of course many, many puzzles to play with, even very rare and interesting ones, and even some I bought: Tritalon, Escape from Alcatraz, Wooden Puzzle Lock 1, and Wooden Puzzle Lock 2. A great weekend!

The latest update by Eric Fuller contained a gorgeous Chicken Puzzle, a interesting looking Bundle of Sticks, and a new release of the famous Visible Burr. I ordered that burr disassembled, and that is the reason there are more pieces in that bag in the picture. I will replace the picture after I had a chance to assemble the puzzle (as usual).

Today I went to GCD to meet many puzzle friends and also see some new puzzles. The nice giveaway puzzle New T Puzzle was no surprise for me, as I was involved in that project. From two puzzle friends I received some of their own work: Mini Bottle and Fibula Puzzle — thank you! His new design Closed Box I got from my puzzle friend Christoph. Not new but interesting are the 1 2 3 and the Double Sliding. The Buffalo Nickel Puzzle is the second of Oskar's 2-dimensional burrs I own, and it is in the beautiful original version. Goal is to free some coin, and this is also the goal of the new Hole Vacancy Coin and Hard-Boiled Coin. Fresh from Hungary arrived the Mandorla (which also exists in different colour schemes). The PUZZLE is a high level interlocking puzzle, which picks up the recent way of using letters in such board burr puzzles. That is almost all I know about it. GCD was a great day once again and I had a lot of fun!

A surprise package from Switzerland — thank you! Peider Grischott took the existing design Double Slideways Burr and created the Double Slideways Burr Plus (incidentially also the original version of the puzzle by Ray Stanton) trying to close the space inside the puzzle. He has now continued his efforts and created the interesting Double Slideways Burr TSP, which has less internal space, yet still functions as a coordinate motion puzzle. The diagonal cuts enforce coordinate motion moves along diagonally to all grid axes. This can further be modified to the: Double Slideways Burr TSP—. The minus in the name suggests that something has happened here. The pieces have been made simpler (notchable now!) This puzzle can still be solved by coordinate motion, but you can also assemble two halves and then move them together in a straight move along one of the grid axes. The pieces look simple and are well known, yet I have not found a reference to a burr with these particular three pairs of pieces. If you know more about this burr, please drop me a message.

From Switzerland I received a litte surprise puzzle, which was a puzzle experiment: Based on the Double Slideways Burr, the Double Slideways Burr Plus was designed, which has three identical pairs of pieces, but with a little less space in it than the version I already have. The manufacturing process seems to me more difficult by this little modification. It turned out that these were indeed the original pieces from the original design (also sold at Cubicdissection), which were modified for the IPP Exchange. Thanks for the nice puzzle!

Stephan sent a giant from Austria he recently designed: Ruebezahl. The name is from popular fairy tales, and this matches this very beautiful puzzle very well. The big caged sticks are quite complex in shape and have 3x3x9 units — the first six piece burr of that kind I have ever seen, with or without cage. The giant came with a second puzzle for support, so new that it did not even have a name. It is a six piece burr in a cage of planks, hence the name Plankton seemed appropriate. Looks very beautiful with these woods, and by the way: have you heard about white nut wood before? Thank you, Stephan!

Today I received the improved versions (second editions) of some very nice Jean Claude Constantin puzzles from him. They are both in compendium and n-ary puzzle group page: Uhrwerk and Bi-Nary. Both are definitely solvable and fun to solve — have solved them myself. The Bi-Nary can be quite confusing at first, but what would you expect from a puzzle combining two different n-ary mechanisms? This one is the first puzzle to implement such a fascinating idea, and it required quite some engineering to get things working right.

About 1.5 years ago I first met Steve Miller, and he told me about his plans to revive the Barcode burr, which has been brought into existence (please see here). He then mentioned that he was working on a high quality puzzle called "fire" to be part of an elemental series. Now here it is: Fire puzzle. If you look at the puzzle and its beautiful looks you might understand why it took so long to produce. It comes in a nice set of boxes and opening them is the easy part. The puzzle does not give away clues how to open it, but there is a leaflet with clues. Only problem: They have been encrypted in a strange alphabet, one additional puzzle to solve! The box is covered with optical illusions and some more clues (or encrypted writings). Additionally, a web site has been created which is also supposed to contain hints. Quite a lot for a single puzzle, and I would expect this also hints for the time needed to solve all that! Wow!

Of all those twisties I have received lately, there are still many left scrambled and waiting to be solved. I wonder if it was a good idea to scramble them, especially the ones with gears. Today I received an easier one I have solved it already a couple of times: Pyraminx Diamond. This new puzzle is also one from the group of twisty octahedra.

This evening I hosted a small puzzle event at my place, now the 3rd already, why I called it "MZPP3" (after MZPP2 last year, the acronym including the city abbreviation). Thanks to all participants for making this a special day with many nice puzzles! Half an hour before the event my latest auction win arrived, and I don't know much about it, but sometimes I like puzzle mysteries: Large Puzzle Bank. From some participants I received some puzzles of their own production: Marble in Cage, Schickspiral, Tom's Hollow Cube, Turnblock 335, and Walton Cube. Now I have some fascinating new puzzle which will help me remember this day!

A beautiful brand new puzzle from Austria: Cubloc S. If you look closely, you will see that it is a six piece burr in a cage, and the cage will come apart, too. While it is not needed for the solution, notice how the different burr colors match the cage colors at the sides!

Today I picked up a late christmas present at customs, which had travelled for the last 1.5 months — maybe carrier and customs did try to figure out what it was and to solve it? It was well worth waiting for and is the latest design in compendium and n-ary puzzle group page by profilic designer Namick Salakhov, and revealed to the public here for the first time. The puzzle is the DITWIBIN, a beautiful puzzle excellently crafted and with beautiful looks — I especially like the two color acrylic frame! The name might seem to have some system behind it and it fact there is: It denotes this puzzle as one with two twisting discs with a binary gray code implemented. Can you guess which part of the name stands for what? This also hints that this is a typical representative of n-ary puzzle: While this puzzle has been created in September 2014, various higher order versions were designed already in August. This makes it a typical family of n-ary puzzles: different number of sliders, different arities of these sliders, and then additionally also different number of discs. Quite fascinating concept! Coming back to this one, it is fun to play with and the moves are nice and easy. You can see a vital part of the mechanics for the interaction between the pieces on the top demonstrating how this puzzle might work. However, there is more to it hidden from view. A clever design! Thank you, Namick!

Originally, I had ordered this puzzle before the recent price increase at Shapeways, but somehow it did not work out and I only received the Helix Burr v2, which I still need to solve. After a second try, I have received the most complicated version of the helical burr series, the 27 move HELLical Burr. By coincidence, this is puzzle number 1666 in my collection, which somehow fits very well. I had my first encounter with this difficult puzzle at the IPP banquet, when Ali handed it to me for solving and I did not manage during that evening.

I found a limited edition token in one of my puzzles! This puzzle took me 2 months including some weeks of experimenting with a computer program and some non-standard techniques. Interesting! If you have not yet guessed which puzzle I am talking about, please have a look at the post exactly 2 months back. It is an epic puzzle and Allard commented on it: "It goes on and on and on", and who was I to contradict! It is a fantastic puzzle and I not only like all the mechanisms in it, but also love the the little stories hidden in it. Thanks for the great puzzle, Brian! Sorry I cannot be more specific here, not to spoil the fun for other solvers.

Just found out that the Karakuri Christmas Presents are on-line on their page now, with the names. Now these puzzles have the correct names on this page: Confetto Box 2, New Parcel Cube, Ring Box 3, and Lock.

Today I could pickup my Karakuri Christmas Presents, some four very nice boxes, who took a long and expensive detour via Customs offices. When I first saw the pictures, I guessed the respective craftsmen/designers, and my knowledge about the special cardboard boxes confirmed my guess. It's 2015 already, so I will put up the entries with the correct craftsmen and will not ask the usual question about them, just lacking the proper names for: X-mas present 1, X-mas present 2, X-mas present 3, and X-mas present 4.

The new year had a great start and the first puzzle update is the first puzzles added this year, arriving in package from puzzle friend Wil Strijbos. There are three nice boxed burrs made from bamboo designed and manufactured by a Chinese guy whose name I do not know: Checker-board interlock box, Interlock the red square box (A), and Interlock the red square box (B). Nice little interlocking challenges and well crafted! Additionally I received some very tangled nails: Nails Duo 2. Thank you for this challenge, Wil!

On the last Christmas day, time to finally unwrap the Dozer and remove it from its packaging (read: 12 piece burr). Read my interesting experiences here: Burr Zoo.

Christmas is approaching fast and today I received three packages via three different ways (Customs and two different carriers). The first one is a Karakuri Christmas present from 2010, and a box I was looking for since I played with it in the 2011 IPP31 Design Competition, where it won a honorable mention. The box has a theme fitting the season: House with Trees has four little x-mas trees on it. The second puzzle is Stephan Baumegger's latest try to put additional pieces into burrs. This time a bigger 12 piece burr with a little Bulldozer in it: Dozer. Not an animal piece, but something for the Burr Zoo, to be completed when I have disassembled it, and from what I can say now it is very nice an high quality. The third one was also a nice entry in IPP Design Competition puzzle, from 2009: Qboid. In the picture, I picked up an idea from Gabriel Fernandez' blog — usually you are supposed to build a 2x2x3 cuboid. The puzzle has many different challenges (over 1000) to build, so I might start with some easy ones first. A nice early christmas present from my puzzle friend Michel. Thank you!

On my web site I have the honour to host the latest extended version of Goh Pit Khiam's excellent article "The Design of N-ary Mechanical Puzzles", see compendium reference [12]. The update today includes some major extensions and new puzzles mainly, from page 28 onwards, featuring: The Power Box, Racktangle, an illustrated overview of some mixed base Power Tower examples, including a simplification of this concept.

A package from Nowstore in Hong Kong with the latest two from the DaYan Gem series: DaYan Gem VI is a 3x3x3 with some fancy extra moves and which does not look like a Rubik's cube at all. DaYan Gem VIII is a face turning and tip turning truncated tetrahedron.

Today Bernhard kindly invited to a small and very nice puzzle party and beside the lot of fun at the meeting and with the other puzzlers there, I was also able to acquire some special prototypes and new puzzles. The prototypes are cubes and a cuboid with rotations from Jos Bergmans: United, Pirouette, Garmbaad, and one with six identical pieces by Yavuz Demirhan: Six Spades. The latest two puzzles by William Hu and Logan Kleinwaks have also been available already: Chain and Six Iberian Lynxes. The Chain offers nice rotations, while the Six Iberian Lynxes is composed of six identical pieces and has level 9. Two extra pieces are supplied and if you replace two of the standard pieces with these, you will get another puzzle with level 19.
Added on 2014-11-20
Today a massive cube arrived from Stephan: Cube 81 by C.K.Leung. As the name suggests, it requires 81 moves to remove the first piece. The whole puzzle is built around a big column, and before disassembling it completely, only the nut wood pieces move. Very nice fit and high quality. Nice to play with, also the size is just the right choice for playing.
Update on 2014-11-19
Success: I have now disassembled Gobi. It took some time, so I also wrote a long report of this expedition into the Gobi, see my Burr Zoo page.

Look! I received a friend for my koala to play with! Today the long awaited Katie Koala and her joey Verne limited edition puzzle arrived. It is the 20th anniversary limited edition by Brian Young and a really beautiful and heavy wooden Koala. A lot of stuff must be inside considering the weight. Will take some time before I will be able to solve it, I guess — lots of puzzling fun! The other koala is sitting on another special puzzle which arrived today: a 3D printed reproduction of the Stickman Box number 5, sometimes called "Borg Box". Another Brian made this possible: Brian Pletcher modelled, prepared, and assembled it. Two truely interesting puzzles!

Do you know the "Gumball 3000"? It is a famous (or infamous?) race on public streets, running through several continents, but in some places considered an illegal street race. This is the theme for the latest burr Stephan Baumegger designed and built: Gumball 3K. With its wood grains it is a real beauty and looks a bit like a ball (the trophy for this race?). Although it is not really an 18 pieces burr, I put it into this 18 pieces burr group, as the two extra pieces are well hidden. These pieces are cars and not animals, but close enough for the theme, so I put it into the Burr Zoo to be described when I have disassembled it and revealed the two cars inside. And after all, some fast cars do have animal names, so I should put this puzzle into the Burr Zoo! At the end, with the level, it does not seem an overly difficult burr, but the car pieces makes it a bit more difficult and it is definitely looking beautiful! You can find more pictures on Stephan's facebook page Puzzleisure.

Yesterday I went to the Dutch Cube Day and met many old and new puzzle friends there, from different continents even! A very nice event!
From Jack I arrived a special version of his and Pit Khiam's Power Tower participating in this year's IPP Design Competition: Power Tower (mixed base, variable stage). This version comes with a lot of extra pieces and a stopper that allows to select between 3 and 6 stages, and also allows to select an arbitrary combination of binary, ternary, and quaternary pieces. This will intermingle sequences of different arity and may be quite confusing to solve. Not only the craftsmanship is amazing in this puzzle, but also the sheer number of pieces that come with it. The standard configuration is three binary pieces and plays nicely and easily.
The Barcode Burr (printed) is a 3D printed reproduction of the famous wooden version by Lee. Steve engineered and created these printed version in a limited quantity and is a great opportunity to study this fascinating mechanism. In a partial sale of a whole collection, I managed to get some classic puzzles: Computer Puzzler No 2, Computer Puzzler No 5, Double Loop, Trapeze variant, and Unknown Disentanglement 2. All seven puzzles mentioned so far are part of the compendium and n-ary puzzle group page.
From Michel I received a (customized!) Puzzle Wristband and an Expand A Ball. He was cooperating with Robrecht who created the Ladybird and Larva. The first one was part of the IPP Design Competition, the latter one is a simpler version including the same maze. That makes the names of father (Ladybird) and son (Larva) seem most appropriate, and they are both nicely designed and crafted puzzles.
Straight from Hungary Oliver brought a nice Smart Egg - Skull Egg, which is the most difficult of the whole recently released series.
Beside the Power Tower already mentioned, Jack also made a nice theme puzzle, the DCD-burr. Please look at the picture to see why it is a DCD theme puzzle. He was not the only high level burr designer and craftsman present, but also Alfons, from whom I received some nice beauties: Gobi is one of the latest Burr Zoo members. Jadimex is a nice easy puzzle of three boards and three sticks. Maltese looks a bit like a cross of 18 piece burr and a Maltese cross (sic!). Then Jalpa is one from the 18 pieces burr group.
The Letterbox is a nice design by Christoph (one of the guys I once helped with Burr-Tools). So now I also own "my first Lohe", and Chris also this of this design as his best.
The Rammelkast is a trick box by Theo and you hear something going on inside when tilting it. Fascinating and also nice woodwork.
From Bernhard I received as recent re-release Wunder-Puzzle, and then some new complicated interlocking cubes/cuboidsby William Hu: Coo-inter-pack seems to incorporate coordinate motion with interlocking and packing. I am curious to see how this works! Writhing Snake Cube has some snake pieces performing strange rotational moves. Zmije is one of Vinco's puzzles where you do not know how to open it and where the pieces end.
As a present, each participant of DCD received a 6^3 Board Burr, which is a variation of his IPP Exchange puzzle Cubic Board Burr — as Peter demonstrated in his interesting talk.
Added on 2014-10-20
From Shapeways I received a Helix Burr v2, which is a higher level variant of the Helical Burr. My order also included the HELLical Burr (27 moves for the first piece) before the pricing scheme went up, but unfortunately there were problems during printing and I only received this one. At IPP I already failed to solve the HELLical Burr, so maybe I will solve this 16 move variant some near time in the future.

Back from the Spiel games fair in Essen I brought some interesting puzzles with me, some of them brand new. My first visit was to Jean-Claude Constantin, and he had some new puzzles compendium and n-ary puzzle group page for me (even after so many new ones he made for IPP): Based on the N522 he demonstrated the generalization aspect of this class very well: He created different sizes of the puzzle from a 2+2-slider N5, via the 3+3-slider N52, and so on until the 10+10 slider N522222222. Of course I was not able to buy all of them, but have some nice representatives. The N5 is good for beginners, while the N52 is a good challenge for an average puzzler, and the N522222222 may not be solved anytime at all. But all of them share the same principle and design. A new design is the Bi-Nary, which combines the this mechanism (of the N5x) with the one of the Six Bottles. It is a combination of two ternary mechanisms, hence the name, and can be quite confusing to solve.
The other puzzles by Constantin are a bit more normal again: Schmuckkiste, Einstein-Box, Spinnennetz, and Picture Ball Maze.
The Romanian Puzzle Box Small looks like a reproduction of a typical Sorrento Trick Box, but the key is hidden in a different place. The rest of the puzzles I bought at Rombol, including some new interlocking puzzles: Assembly Cube, Rondo Turco, Open Crochet Cube, Poco Loco, Framework, and Fan Puzzle.

A package from Puzzlemaster today, starting with some of their own brand: Brass Treasure Chest is a very small puzzle box by Rocky Chiaro, Great Collision one of the group of similar puzzles by Doug Engel, and The Yak Puzzle and Brontosaurus are fierce disentanglement puzzles by Dick Hess. Writer's Block is "an Oskar" using real pens as parts. The Brain is the new version of the puzzle in compendium and n-ary puzzle group page. Cast Galaxy is a fascinating puzzle by Bram Cohen and the latest Hanayama puzzle. At the IPP33 Design Competition it was awarded an "honorable mention". Hourglass is one of those Yamamoto puzzles with high level and rotations, and it also looks nice!

A long time ago, in a galaxy far, far away ... These puzzles remind me of something I have seen in cinema before. You may have recognized that the new Typhyter standing next to the Droid is not just another 18 pieces burr, but also a beautiful piece of art. This puzzle arrived today in a package from Stephan Baumegger with two other gorgeous novelties: Troika has only three pieces, but looking at the level you see it is pretty hard. From "pretty hard" to "pretty heart": Caught Heart is a beautiful interlocking puzzle touching the borders of the puzzle box category: the heart piece is the only piece that can be removed, and for the others several tilting moves are required. I am sure it will be officially published on the Puzzleisure page soon, and sorry for the bad pun!

Usually once every year since 1978 the biggest puzzle related event takes place: the IPP (International Puzzle Party). I have just come back from this amazing event where I met many old and new puzzle friends and brought back some nice puzzles. You can see my "haul" in the picture on the left. About 100 puzzles are from the Edward Hordern Puzzle Exchange, where you bring about 100 copies of a new puzzle and exchange with 100 other puzzlers. Please see the special page for these puzzles. My puzzle in the Exchange was the Cross + Crown 2013, which is based on a design patented in 1913, 100 years ago. It is an n-ary puzzle. To my big surprise, I received a bigger version of it from my Exchange assistant Kevin Sadler: Cross + Crown 7 This is also n-ary and has an amazing 4802 moves to solve! Thank you! IPP34 Exchange

At IPP, I received a London Lines Puzz-eLLe as a gift from the organizers, and a little IPP34 Necklace Burr from Brian Young. Thank you! The IPP also features the Nob Yoshigahara Puzzle Design Competition. Beside some puzzles which are also in the Exchange, I managed to get some rare n-ary puzzles from the Design Competition: Complementary P-arity and Num Lock. I also bought a smaller version of the Naked Secret Box Red.

At the Puzzleparty, I bought various nice puzzles: Frame+Loop Septet is a n-ary puzzle I was missing in the set, and probably no others will be produced of this kind. From Kirill, I got a Valentine's puzzle as a swap. Tom Lensch and Frans de Vreugd sold me some old but nice of Frans' designs: Quantum Entanglement Exchange and Extreme Boxed Burr. Just a day before IPP, the new Doors and Drawers was ready, and I just had to buy this puzzle. It is a puzzle box/sequential discovery/interlocking/packing puzzle — very nice! I got a Sandfield's Banded Dovetails, which is the predecessor of the version I already have and then I found a Rhombic Maze Burr " many puzzles in one, with up to a several hundereds of moves. This one comes with a whole book of challenges! From Otis I received a Secret Box as a swap for one of my nice Acrobat puzzles. The haul is concluded with a new Indian Trick Lock.

With so many puzzles to solve, I am just starting to solve and will replace the pictures with solved versions once I have solved the corresponding puzzles. This may well take some year or more.

Update: The compendium has been updated and in total 10 new n-ary puzzles from IPP found their way in.

This weekend brought a package from Jerry McFarland with a second Pin Burr. It is actually the first Pin Burr, Pin Burr 1. From the outside, it looks as beautiful as the Pin Burr 2 and similar from the outside, but the mechanism is very different. The pins are used in a different way here, and the creative new way of using pins and magnets is the first time I see this mechanism in any puzzle. A nice puzzle to play with!

Today a package from Hong Kong with some nice Twisties. After successfully solving a 4x4x6 without help last weekend (has been lying around at a friend's place being scrambled by a neighbor some time ago), I received a new cuboid today: 2x4x6 Pillow Cuboid. Will surely give it a try and do not expect it to be overly difficult to solve — famous last words! With it came a very easy puzzle: Pyraminx Duo. The last in this order is a Dino Skewb. Actually I had this puzzle in a Shapeways version for some time, it is an F-Skewb, which is more a collector's item than for solving. Now I can try to solve the Dino Skewb without remorse.

Today I received some of the latest works from Alfons Eyckmans. Very beautiful puzzles and all interesting designs! The Lolly Box 4 is a brand new and unpublished design. It has 5 lollies ready to grab, but they won't come out easily. The Rubicon was my selection from the sticks in a four board frame series, which Alfons has been working on recently. Beside the beautiful looks it has the piece shapes as most distinguishing feature: big boards, short sticks, long sticks, and also small boards! With the next one I took another visit to the Burr Zoo: Adam and Eve in Paradise. Have a look into the Burr Zoo page, the review is already there, with some nice pictures! Paraugas is some new shape: A central column with some 8 burr sticks around it. Even though this is a puzzle solvable with Burr-Tools, you can also start with some fancy rotation of the upper layer of pieces, trying to screw things up a bit. The next additions are some in the traditional 18 pieces burr group: Mayhem is a chaotic puzzle with hooked pieces, similar to Nightmare, just more complicated. Tadpoles is a nearly traditional 18 pieces burr (only six pieces of other shape, extended at one end), which tries to entertain the solver by providing a nontrivial level for several pieces. The Microburr is a truely small burr designed and built by Maurice Vigouroux. Thank you for all your nice puzzles, Alfons!

Every year Rainer Popp releases one of his new trick lock designs, which are known as Popplocks. They are all custom made and some of the most sophisticated trick lock designs. So far I have only collected the Popplocks with even numbers: T2 T4 T6 T8. This year is an exception: The Popplock T9 was released and immediately added to my collection. It looks massive and valuable as all these locks and this one seems to have a whole series of steps and tricks built in. And this one has a key, may be a hint for opening it. I have already started solving it, found something already, but I am still far from solving this beauty.

This update shows a new puzzle based on a completely new design: Pin Burr 2 is a burr by Jerry McFarland which uses a pin-maze-mechanism and is based on a binary sequence. This makes it part of compendium and n-ary puzzle group page. The binary sequence is not based on the Gray Code, like Chinese Rings, but is more like how computers count. Making the puzzle more interesting (much more interesting!), Jerry has included a trick in the binary sequence, and after the control piece and the bit pieces have been removed, the frame does not come apart immediately, but you have to find another trick which Jerry included — reminds me of the excellent Burrblock, but the trick is completely different. The complicated frame is a big development from the prototype which I had the honour of testing, commenting and comparing with the final version. That puzzle has a frame of the Quadlock 4, while the Pin Burr 2 has a more sophisticated frame and more complicated piece shapes. These pieces are also crafted from nice woods (including ebony) and this leads to the most obvious aspect I have not covered yet: The puzzle just looks beautiful! Please have a look at the picture yourself and also into the compendium entry for some nicer pictures. These fine woods lead to the last aspect I would like to mention here: The puzzle is quite heavy, which makes it nice to hold and fun to play with. An excellent addition to my collection!

After yesterday's update with the two big puzzles coming in a separate package each, today I received a package from Eric containing nice puzzles from two companies: Cubicdissection and Raleigh Puzzles. The first one is a first design of the new designer Dan Fast, who was known for twisty puzzle videos and just recently extended his reviews to wooden burr puzzles and has now designed his first own very original design: Shake Something. The name will tell you something about the solution — interesting! Then there are two William Hu designs: Ring Lock involving rotations and Welded Burr, which is a three piece burr, believe me! From the less expensive Raleigh Puzzles range I received two classics I did not have yet: Slideways and Missing Notch.

Today two nice little packages from two of my puzzle friends. Feels a bit like X-mas and Easter on one day. Well actually, there is an egg in one of the packages, and the other is wood (recycled X-mas tree? Definitely not!). They are special puzzles, both are difficult and very good looking. That is where the similarities ends. So what are these mysterious puzzles?

The first one is a big burr. And when I mean big, I am talking about a configuration of 12x15x16. That is 43 pieces in total! However, it is not a puzzle that eats up all your remaining shelf space, as it has been created in nice 8mm sticks, an excellent choice also for playing. You may have guessed already, it's the C2-1. It was designed by C K Leung and built by Stephan Baumegger. Only 5 of them were built (and licensed) and Yvon from Canada was also involved in this project. My first impression is "Wow!" and I am curious if I will be able to disassemble (and reassemble) it without help.

The second one is not another easter egg, but Wil Strijbos' newest project, the: EGG. The puzzle looks fantastic and like the high quality work we know from Wil's puzzles. It also feels nicely solid and heavy, as usual for these puzzles. This is all I can tell about the puzzle at the moment. No idea what is going on inside and how to open it. But that is the idea behind it, isn't it? Looking forward to see how this puzzle works and opens, but that may take quite some time.

Directly from the designer I received two nice puzzle locks: First I was looking for the Burgh Lock, and then luckily the brand new Swing Lock became available. They are quite different from each other and look beautiful (believe me, the orange color is much nicer in reality than on the picture). I have already found some interesting surprises before even attempting to solve, so these lock surely will prove very interesting!

Today a package from Stephan with some of the latest designs from Austria and both very nicely designed and built. "These aren't the droids you're looking for!" Remember this quote? Well, there is a droid I have been looking for, and this cute puzzle has arrived today: Droid. Looks like a wooden relative of the famous R2-D2 from Star-Wars. The second puzzle is another framed traditional 18 pieces burr: Enmarcado. Wrong again! This is the first self-framing burr of this kind, which means that the frame is not solid but mere sticks attached to the burr pieces which make up the frame. This is based on an idea Ronald had years ago: Self-Framing Burr.

There are several ways to celebrate the Dutch King on King's day, and one is Wil's Koningsdag Puzzle Treffen, which I visited today. Met many nice puzzle friends there, had a look at a very small percentage of Wil's collection, and of course broght home some new puzzles: It started with a pre-order, which Michel handed over to me, four wooden puzzle locks: The Fiendishly Perplexing Lock, The Utterly A-Maze-Ing Lock, The Cunningly Complex Lock, and The Ultimate Combination Lock. Then I went for some metal puzzles:Lock Nut Bolt, Little Gordians Knot, including the latest Cast puzzle: Cast U and U. The next two are tiny interlocking puzzles I have never seen before. Lacking Japanese language skills, I still do not know how they are called and who designed them: 12 Piece Japanese Interlocking Puzzle, 15 Piece Japanese Interlocking Puzzle. For the last two, I know the designer and that they have been produced in the New Pelikan Workshop: Cubax and Konstrukt. Did you notice something familiar? Well, the Little Gordians Knot is a member of compendium and n-ary puzzle group page already, in a slightly different shape.

I picked up some different old and new puzzles: Swiss Cow (Vache Rouge) (original naef version), Matchbox, Big Interlocking Cube (an unknown cube in a very rough build from an unknown craftsman and designer; none of the present experts was able to identify it).
Then some vintage additions to compendium and n-ary puzzle group page: New Puzzle Rings 3 and New Puzzle Rings 5.
From Bernhard I picked up some nice pre-ordered items (some of them were sold out already): Petit Puzzle, Rotator, Keyhole, Turnkey, Irene Alternate, and Two Wheeled Cube.

News update on 2014-04-01
No April's fool, but I have really solved the Bicomplementary formation b/b:1/2 puzzle and removed all the sticks and bars from the puzzle. After the long interweaved-binary sequence for the first piece, there are a couple of moves for each piece (I would estimate no more than 10 per piece), including some half-unit moves taking the half-notches into account. Most of the strange moves I found earlier now appeared in the sequence for a piece. While removing the pieces, I carefully arranged the pieces in a way such that I would know which piece would belong where. Even with this information the puzzle is difficult enough to reassemble, as you have to know the order in which the pieces get back in, and what the configuration of the other pieces should be at that point. Luckily and unlike the disassembly you can see through the hole and see what has to be aligned to make room for the new piece. A real boxed burr experience. Very nice concept, I like it!
Added on 2014-03-29
Today two special updates:
Bicomplementary formation b/b:1/2 This puzzle update is something special because it is presented to the public for the first time. Is this beautiful red and shiny box a burr, is it an n-ary puzzle? Well, it seems it is both. It clearly has some Gray code moves in it and then also some burr-like moves that are not following Gray codes at all. The name Bicomplementary formation b/b:1/2 tries to summarize that there are two groups of pieces (bars and sticks), which both follow a binary GC move pattern at first and are interlocked. Then some nice half notches based moves appear that are usually only found in burrs by Bill Cutler and Jerry McFarland. Some solving experiences: After finding out about the binary GC first, the first group of moves becomes pretty evident. However, at a later point this sequence ends abruptly. Now you are on your own, like with high level burrs: searching for possible moves without being able to look into the box. After a while a pattern becomes clear and then the first piece comes out. Fascinating puzzle! It is a worthy new addition to the compendium and n-ary puzzle group page. Clever design, Namick!

Today some very nice and beautiful burr puzzles from Alfons: The Mino and Jucar are a new type of burr actively discussed on facebook. Alfons made the Mino with nicely grained pieces for me, but additionally he also included the ones that were first built and presented on facebook -- as a special collector's item. After all the nice 18 pieces burrs lately, the Sand Witch and the Kameleon are a good distraction, with a mixture of different piece shapes in one burr. The Kameleon seems to mix them as the real animal mixes colors on its skin. Then there is one addition to the Burr Zoo: It seems, Alfons has finally found the master of all those pets he locked into the burrs before, the The Devil and his Pet.

When I had some twisty puzzles visiting last weekend together with my puzzle friends, I just had to go to Calvin's store afterwards and order some. The arrived today already, which is very quick: 3x3x3 Pitcher Octo-Star Cube, Evil Eye II Dodecahedron, and Curvy Copter Plus

Recently I made a visit to the zoo and wrote up a little report on the things I have seen there. Wrong page, you think? Well, it was a zoo of Animal Burrs, and the report is the new Burr Zoo group page. Enjoy reading!

Recently I have been playing a lot with some "Animal Burrs", how I like to call them: traditional traditional 18 pieces burrs, which have one or two extra pieces hidden inside that have the form of an animal. I am in the middle of working my way through the Devil's pet family. I have completely disassembled (and therefore freed) Devil's Pet 1 and Devil's Pet 2. Two pieces came out from Devil's Pet 3 already and next will be Devil's Pet 4. Now today I have received a package from Stephan with some of his latest creations in this field. The Beware of the Snake is an 18 pieces burr and is the home of a snake, which is currently in the wild and needs to go back into the burr. All these animal puzzles so far have been 18(+x) piece burrs with very static animals — not much space in there. The Camelride has only 12(+1) pieces, but the camel moves a lot even early in the solution. Nice puzzles in this group and beautiful to look at!

From Alfons I received a package full of very nice puzzles, mostly traditional 18 pieces burrs. The first is a traditional 18 pieces burr, although not of traditional shape: Saturn, and looks a bit like the Crusade. Then there are three traditional ones with high and very high level: Minerva, Morpheus, and Apollo; all with nice exotic woods. The Lange Wapper 54-2 is a small version and slight variant of the Lange Wapper 54. It has pieces of 10 units length (not the standard 8), but with a unit size about half the one of the other burrs, it is a nice tiny puzzle -- blending in into the class of small 18 pieces burrs that became popular recently. The last one is The Box, which looks like a puzzle box, but I would rather call it an interlocking puzzle, maybe even a burr. When playing with it, you will find that it behaves like one of these sophisticated Japanese Karakuri puzzle boxes, but looking at the inside, you will find a core and some hooked panels that look more like an interlocking or burr puzzle. To me it is a burr behaving a bit like a puzzle box.
News update on 2014-01-14
In the meantime, I have solved all the Karakuri X-mas presents, and Iwahara's little box with the two devices took me longest to solve. All very fascinating puzzles of completely different kinds. Today I have received my membership letter with the solution to the names and craftsmen quiz (I did not need the solutions to the puzzles any more). Seems I was right with my guess and can now uncover: Pirates Box by Miyamoto, Bean Bag Drawer by Iwahara, Expansion IV-2 by Kamei, and Ring Box 2 by Kawashima.

I wish you all a Merry Christmas and a happy and puzzling New Year!

Now look at that! I finally managed to remove the second and then also the third and fourth piece of the Columbus. Must have been some 60 or 70 more moves, but I was not able to count. Had to concentrate on the move sequences, which are really fascinating. Sometimes after a few moves you do not even know how to get back! Nice to solve.

Today a nice package from Dan arrived, who found a nice puzzle for me. It is an Electro 1, a traditional entry for both compendium and n-ary puzzle group page. Thank you, Dan!

I am still solving for the second piece of the Columbus burr received last week, and have found some very interesting moves — must be close! What other ways are there to prepare for Christmas time? Perhaps with some season's greetings from Japan with some Karakuri X-mas presents arrived today: Xmas 1, Xmas 2, Xmas 3, and Xmas 4. I do not know the names of these little beauties, but I am sure about who created which. If you would like to guess who was the craftsman for which, please drop me a mail. I will not make it too easy here by telling you which craftsmen I selected, but for some there is a pretty obvious style and I am convinced I know who is responsible for which (and then there are also the colorful cardboard boxes ...). Later I will provide an update with the names and craftsmen, but that will usually take until next year.

Today a nice little traditional 18 pieces burr from Alfons Eyckmans: Columbus. It only takes 7 moves to remove the first piece, so it should be easy, right? Wrong! Alltogether there are 114 moves required for the full disassembly so the puzzle is actually getting more difficult to the end. If you have a look at the pictures, be assured that the nice exotic woods look much better in reality! Thank you, Alfons!

Today two packages with very interesting and nice puzzles arrived. The first one contains a Popplock T8. This is not only a huge lock, but also looks complicated and can be opened, although it does not come with a key. And by the way, it nicely extends the sequence of Popplocks I have: T2, T4, T6, T8.

Today a package from Azerbaijanian designer Namick Salakhov arrived, containing a new special puzzle for compendium and n-ary puzzle group page. Thank you, Namick!
Railing with Draining This puzzle update is something special because it is presented to the public for the first time. It is a nice sliding pieces puzzle, which is ternary, but needs less pieces than other puzzles of that type. While the Tern Key puzzle employs two switches between each two sliders, this puzzle only has one switch between each two sliders. Let's see if you can figure out where the name Railing with Draining ternary comes from. I find it quite obvious if you have a look at how the puzzle looks like and how it works. Please click on the thumbnails to get a better view of the detail pictures.
Today also a second package with some early Christmas presents arrived from John Lin (Customs officers did not believe that but insisted it was commercial): Some nice new Skewb based puzzles: Squished Skewb (the name says all how this puzzle looks like — it is not a Skewb and not cubic), and Skewb Curvy Rhombohedron. Both are of high quality and have the nice clicking Skewb mechanism I like. Thank you, John!

Today two packages with nice puzzles for compendium and n-ary puzzle group page arrived. The first contained a Octet for heavy disentanglement (luckily I managed the smaller Sextet yesterday without entangling myself). The second one a whole load of Frequency Doublers: 1, 2, 3. Unfortunately, that last one is not for me and will travel on, but I was able to study and solve this new puzzle — for research purposes, of course!

The other package was from Alfons Eyckmans. It contains a zoo of some more animals trapped in an 18 pieces burr. Can you find out which the others are? I have two such puzzles already. When I asked Alfons for a new one he created, it turned out that there were 4 different variations already. The new pets are all diabolical animals crafted in nice woods: Devil's Pet 1, Devil's Pet 2, Devil's Pet 3, and Devil's Pet 4. Once freed, they all look a bit different, but all like some sort of hellhound. In case I needed it against such fierce creatures, Alfons included a sword in my package: Damocles, whose name tells me it might not be easy to get out and to use. It employs the same general idea like the recently published Excalibur, but the sword itself is completely different.

After the n-ary news of last weekend, a package from Azerbaijanian designer Namick Salakhov arrived, containing two special puzzles for compendium and n-ary puzzle group page. The first puzzle from this package has been on an oddyssey already. It nearly reached me a couple of months ago, but then something bad happened to the package and for some reason it returned home. Now the Binary Bud is with me, and it is the one that has been in the compendium since the IPP33 Design Competition, in which this design took part this year. It is a very nice little binary puzzle.
GC machine ternary The second puzzle is something special because it is presented to the public for the first time on this web page (and also in the compendium). It is also special because of the nice technical look, that underlines the name GC machine ternary and also special because of the nice new mechanism. There are five sliders and four wheels in this mechanism, and a control knob. The control knob ensures that exactly one slider may move at a time (indicated by the numbers on it), while the weels link the sliders together to a ternary mechanism. The sliders of course have three positions and the last picture shows the goal configuration with all five sliders pulled out as far as possible. A unique and very nice concept, and also fun to play with, believe me! It is contained in the compendium, as it is a ternary puzzle — hence the name, while the "GC" in the name stands for "Gray Code", of course.Please click on the thumbnails to get a better view of the detail pictures.

Second puzzle event in a week was going to the "Spiel" in Essen and meeting puzzlers from different countries and even continents there. At Jean-Claude Constantin's booth I expected to see one puzzle for the compendium and n-ary puzzle group page. Instead he pulled out one after another until six new designs lay in front of me, so this is a big update not only for my web page, but also for the compendium. The new puzzles are Steuerrad, Spiralschloss, Uhrwerk, Seestern, 522, and Labynary. Some have extra challenges of hidden ball mazes, and they are of arities 2, 3, and 11. What better way to invite you to look into the compendium, where you will find more details about the puzzles!
Of course I also got some other puzzles from Jean-Claude, like one of his Light Bulbs and a Trick Lock. This lock is something I have been searching for some time. It has 3 independent locking mechanisms and they require 12 steps — a true beast!
At the Rombol booth I found some interesting new designs I did not have: T-one, Rotpack 1, Sliced Bread, and Gear.

Last weekend was DCD in the Netherlands and I brought back many puzzles again: From Wil I got a Trapezoid Symmetry Puzzle and the two latest cast puzzles from Japan, still in their original Japanese packag: G&G and Cylinder. Bernhard had some nice pre-orders for me (some sold out now already): Coaxial, Mysterious Galaxy, and Galaxy Z. Oskar gave me one of his Impossiburrs (can you see the geometry?), and from Tony Fisher one of his latest originals, a Starpad (where did the rest of that Starminx go?). After meeting Jack Krijnen, I now had some of his old and new creations: The Cube (interesting design from 1980), Tippy (downsized version of the Tipperary, both in complexity and real size), Elevenses, Framed!, and Grandpa Framed (two additions to the 18 pieces burr group, the first ones with frame). The last one is a Grandfather Burr (by W. van der Poel), put into a frame. From the designer of the Grandfather Burr, I got an unknown Puzzle of 3 joined 4 piece burrs (probably by Interlocking Puzzles). After the talks (see below), I received a Perrier Bottle and three nice folding puzzles. I was also looking for a Quatro -- of course Marcel had one for sale. Finally, I received a nice Carthesian Wallet from Michel.
At the DCD I also gave a lecture about my compendium. You can download the slides here, but I did a lot of talking, which is not included in the slides.

Today a nice little package from Austria, from Stephan Baumegger. It contained one of his latest creations, an Excalibur. The name and the look of the nicely crafted puzzle suggest that you need force to pull out the sword, but in reality mental strength is required: It is a high level burr with 9 pieces in a box.

At MPP (Midlands Puzzle Party) Adin Townsend presented a ternary puzzle created from Lego. It is closely related to the Crazy Elephant Dance and works the same way. When building instructions were published for this puzzle, I built myself a Lego Ternary Gray Code Puzzle and after verification that it behaved correctly, I put it into n-ary puzzle group page and of course the Compendium.

Earlier than expected I received a package of nice puzzles from Tom Lensch — very nice craftmanship! The order dates back to last year's IPP when I met the designer Ken Irvine and was fortunate to order some of his new designs: K22 Multiwood Cube, K24 Walnut Cube (named after the wood of the prototype), and K27 Accordion Cube (one wood as opposed to Eric's Multiwood version I already have).
Special Update on 2013-08-30
I know that there are many puzzlers interested in the n-ary Puzzle Group. There are more such puzzles than shown on this page, so I have created a compendium of all of them known to me over the last months, containing more data about the puzzles, a formal definition, and some interesting mathematical properties. All that is now published in the:
Compendium of Chinese-Rings-Like Puzzles

From Stephan Baumegger I received an 18 pieces burr, which he designed in a box. This is not only the first design of this kind I know, but also a beautifully crafted puzzle: Centauri. It has level 13 (i.e. 13 moves to take out the first piece), so it should be easy. Think again: The following pieces require another 141, 34, 8, and 17 moves, so it is a real monster to solve. Will keep me busy for a very long time, I guess.

The Hexadecimal Puzzle was created by Binary Arts in the 1980s and only very few still seem to exist today. Recently Creative Crafthouse has obtained the permission of the patent holder and has created limited edition of this puzzle, the Hexadecimal Puzzle 2013. It has various setting for various challenges, one of which makes it part of the n-ary Puzzle Group. This version of the puzzle is well crafted and fun to play with. It seems to be a very exact reproduction of the original puzzle, enhanced with some laser cutting techniques that have not been available back in the 1980s.
With this puzzle came some other nice puzzles of various kinds: Boxed Burr, Odd Man Out Cube, Safecracker, and Double Trouble

Some late Sunday update: No puzzles but an update to one of my latest acquisition, the Generation Lock, the new record puzzle in the n-ary Puzzle Group.

After some time a nice addition to the 18 piece burr group: Free the Monkeys. It looks like a traditional 18 pieces burr, right? Well it isn't. It's a 20 pieces burr, and two monkey shaped pieces are hidden inside. It is very close to an 18 pieces burr, so I am leaving it in this group anyway.

Generation Lock and Lock 250+ My puzzle friend Wil sent me a very nice surprise package which arrived this weekend. Only when I opened it, I knew what it was -- and I recognized the mechanism and was completey perplexed. The brand new Generation Lock is a much bigger version of the Lock 250+. The latter one has 4 sliding rivets, with arity 6, i.e. each (but the lowest) has 6 positions, and requires 310 moves to open. The new one has 8 sliding rivets, with arity 15, setting a new overall record in the n-ary Puzzle Group. Question is how many moves to open? After my first approximation, the name of the lock made sense to me, but I will not tell you right now, as I am making it a little quiz. How many moves to open? Can you guess or even better calculate?

When Bernhard's latest annoucement came out, I was the first to place an order and this already 12 minutes after the initial announcement. Hard times! Three nice burr puzzles arrived today, two are my first ones from Yavuz Demirhan, who has not been known as a designer for very long, but has been very creative lately (just see Puzzlewillbeplayed): Columnata 2P3C and Estergon. I probably do not have to introduce the name Osanori Yamamoto to you; he designed a puzzle whose name matches current weather conditions in Germany, the Ice Pillar.

Today a special world record celebration update: Some nice high level burrs created by Alfons Eyckmans. For starters a Toaster, an unusual 9 piece burr. Then some exquisit servings of the 18 piece burr menu: a puzzle creating a Nightmare already while consuming (with a lot of odd shaped ingredients), followed by a difficult to digest The Barones, and then followed by the Excelsior course leaving some taste of highest complexity. All joking aside, this last one is the reason why this is a celebration update. This puzzle is a cooperation by Jack Krijnen and Alfons Eyckmans leading to the current world record for traditional 18 pieces burrs: 156 moves for the first piece!

Earlier than expected a huge package from Shapeways with some very well packaged puzzles: a Tubular Burr - many rotations, what else! A Moby Maze - it only has one surface, but you have to keep two sides in focus for solving. A Rotary Cub - a puzzle with many rotations by Greg and more moves for disassembly than assembly! Quickstep - high level "void cube". Although I have solved all but the Quickstep in the 15 minutes between unboxing and the pictures, they are very nice and definitely not too easy puzzles from four different categories.

Today a nice little package from India, containing an old Indian Puzzle Lock.
Added on 2013-01-07
The first update for this year are two packages from the east ordered in December: The first one looks like a magic treasure chest from ancient India and it contains three nice Indian trick/puzzle locks: Combination and Key lock, Lock with 5 keys to open, and a traditional Gurjani lock with two keys.
The second package comes even farther from the east, from Hong Kong and contains some of the latest Twisty Puzzles: Dinomorphix (the reason for my order, the others are "just" side orders), a Nautilus (have to find out how to scramble this Square-1 variant), a Master Pyraminx (now I also have a pillowed one), a 2x3x4 Camouflage (I just like 2x3x4, see my TP forum avatar), 3-layer Cheese, and a Bauhina Dodecahedron (not finished stickering yet, but you can't tell from the picture ... ).

Today an update which may lead to discussions whether I have really added some puzzles today. Well, that depends.
After receiving an interesting padlock, I decided to add some padlocks to my gallery that may not be puzzle locks, but have at least some relationship with puzzles. The first one is the reason for today's update: a Master Lock One. This lock uses a slider with movements up/down/left/right to enter a combination, and this combination is not only user-configurable, but may also be arbitrary long! Of course this is only a finite mechanical device, so after some time combinations opening the lock repeat, but it will take a very long while, as some mathematical considerations will show easily. To understand this and to see how this lock works, please have a look at the PDF and the nice interactive demonstration of the mechanism SWF demonstration hosted on toool.nl. If you have a look at these demonstrations, you will notice that there is a puzzle hidden inside this lock, in which four discs have to be turned into the right positions and with each move three discs turn. If the lock did not hide them, it would not be a lock, but a puzzle and might have shown up at Jaap's page. :)
The other two locks are less spectacular: The first one I bought in Italy maybe some 25 years ago, and it is an unsual design, at least here in Europe. It is quite simple, so that you can make it a puzzle to open it: Pushbutton padlock. The second is also unusual for Europe, but I guess every US high scool or college student has something like this Dial combination padlock I bought in Florida over 20 years ago.

Today a package from far, far away waited for me at the customs office, with one of MrPuzzle's latest limited edition. I was lucky to receive it this year already, and so it does not have the usual number 17, but number 6: a very nice L-Burr. Level 4 does not sound complicated, but there are some very nasty rotations involved -- tricky!

I am not sure: Could Christmas be today already? Two packages arrived the same day, one from far west, from Cubicdissection, with three of the latest burr puzzles: Two Halves Cage 4A (not a boxed 6 pieces burr), Moonflight (not a moon rocket), and Uranus (not a 6 pieces burr, but with magnets!).
The second from the far east contained nice X-mas presents: they are two of this year's Karakuri X-mas   presents.

The Cage for 4 Sticks arriving is the reason I did not order this puzzle from Eric today, and I just like the fine grain of the Difou wood. The 18-in-Blocks is a nice addition to both my 18pcs Burrs collection and to the Alfons Eyckmans puzzles.

According to my calender, it's November, but "NovemBURR" might be more appropriate: After I got the three nice high level burrs from Jack Krijnen, I received a package from Alfons Eyckmans today, full of beautiful, very nice, and high or very high level burrs. They are all crafted in a new way than the others I have and are a bit smaller -- good for my storage capacity!
The first ones are boxed burrs and more complicated versions of puzzles with similar names: Lolly Box 2 and Big Havanna's. Then there are two puzzles that have a simple symmetric cage and three simple burr pieces without extensions (like the Devil in Cage). The Rat Trap additionally houses a little "rat", while the Vectes is a recent design with three identical and simple pieces, but high level for such a burr. The Zig Zag and Zig Zag 2 combine plates and burr pieces into very high level puzzles.
The 18 pieces burrs group has received two additions that are located more at the top end levelwise: The Muff has a movement scheme that looks completely different from the Phoenix family and it has a nice level that has many moves also for the second and third pieces, and quite some moves up to the nineth piece! The Baron is a new personal record for Alfons. Recently we have seen the Echo-1 at Puzzle-Place. Like the Echo-1 satellite was launched after the Tiros in the same year, the Echo-1 burr has the same number of moves for the first piece like the Tiros, 150 moves. Now "The Baron" follows these two Burrs and adds one move more to the level, to a total of 151 moves. The current world record holder for traditional 18 pieces burrs with 152, the BSfEP can still claim its title, but is only one more move away. Let's see what we are going to see next!
These were some long notes about my new puzzles. To follow Oskar van Deventer's tradition, here are some quiz questions for you:
  1. What is the sum of the level (first piece only) for all puzzles shown in today's update? Answer: click here (Needs Javascript)
  2. What is the total sum of moves provided in the puzzle pages for today's update (all numbers combined)? Answer: click here (Needs Javascript)
This will keep me busy for quite some time ....

Today I met many old and new but all very nice puzzle friends at Dutch Cube Day (DCD) in Voorburg, close to Den Haag (The Hague). Many intersting conversations and puzzle discussions, solving attempts and also research took place - keep your eyes open for posts on popular puzzle blogs! Beside all that I also picked up some puzzle to bring home to my collection: After receiving a Souvenir gift, my first way was to Bernhard's table, who had his own products for sale and also some from the collection of the late puzzle collector Martin Brockmann, and I picked up: Changing Partners (several puzzles in one, all non-trivial and with rotations), a Caged Burr, and then also three puzzle locks. Then I went to Michel's table whom I have brought some nice puzzles from Essen, and he had some nice puzzles and puzzling objects for me: Three Piece Tetrahedron, a nice sized Falling Rings, a vintage Dutch WWF Masterball, and an Eureka String puzzle. Very close to this table I met one of the high level burr specialists and after some nice conversation I got some pieces of the impressive "tower of burrs" he built recently: Jack's Dozen, Tipperary, and Jiminy Jack - some nice additions to my collection of 18 pieces burrs. Wil had some binary puzzles for me: Left Right Chinese Rings and Matryoshka. Finally, I picked up a solvable version of the 15/14 puzzle from Ton, and TomZ' latest mass produced puzzle. The last puzzle is a real Belgian Maze, but without the quotes, and a really hard maze protecting a precious Euro coin. I played with this puzzle at IPP and today I picked it up from Robrecht.
There have been some additions to the n-ary puzzles group today. Can you find out which ones?

(Comparison of the two generations of Fidgety Rabbits puzzles. Click for large picture)
What happens if you keep rabbits for some time? Right -- they start multiplying! I received some very fidgety rabbits for my collection (post below), and also these rabbits started multiplying and today a stable box with the next generation of fidgety rabbits arrived. These ternary Fidgety Rabbits are bigger than the "old" generation to accomodate more states. There are only six rabbits, but each has now three different states (instead of two), which makes them a perfect addition to the n-ary puzzles family. This new puzzle has been created for the first time, by its designer Namick Salakhovand based on his (copyrighted) design. It is a very clever design I must say -- I see that it scales not only to ternary, but also to higher order, like Namick has told me before. Please see some detail pictures of this puzzle to the right. Thank you, Namick, for this exceptional puzzle! Fidgety Rabbits ternary

Today something special: My first puzzle from Azerbaijan, and also my first package from Azerbaijan. I received a new member of the n-ary puzzles family, a Fidgety Rabbits. This white beauty was part of this year's IPP Design Competition and is a very nice new concept to implement a binary movement scheme. The puzzle came in a beautiful and very stable box, please see the picture. I have never seen a puzzle so well packaged before! Thank you, Namick!

Back from "Essener Spieletage 2012" I came home with some more puzzles: From Jean-Claude Constantin I brought some n-ary Puzzles: a Kugellager 2 I did not have yet and a disentanglement puzzle (which looks binary at first sight, but has yet to be confirmed); the 4 Stones Labyinth is a new puzzle which I first had to solve for the picture; a Combination Lock, a small Zodiac Box, a bigger LabyBox, a 20 Cent and an improved Oval Office; concluded with a rare Hysteresis Key. From Hendrik I got a Snow Mystery (for the winter approaching?) and some nice Siebenstein puzzles: Up and Down (solved for the picture and not as hard as expected, but still challenging) and a Schiebung. At the Philos booth I not only met a nice puzzle friend, but also got some interesting puzzles for a bargain: Cup Puzzle and Arrow Puzzle.

A box from Eric could be picked up at the Customs office today, containing: An Accordion/Disjointed Cube -- an independent design by two designers. I met Ken Irvine (designer of "Accordion") this year at IPP and he had a big collection of his custom designs with him. Unfortunately they were not for sale, but luckily there was more than one woodworker at IPP who picked up some of these designs to produce them. Eric's version is the first one, stay tuned for more Ken Irvine puzzles to come in 2013! The other puzzles are: The Rattle (a packing puzzle, not my main puzzle type interest, but a nice puzzle) and an interlocking puzzle by Greg: 2 Cage 3BB.
Added on 2012-10-11
Now back to regular updates: From Arteludes three nice puzzles, Cannich (for my Alfons Eyckmanns Burr Collection), Simple UC Trapped (a nice puzzle by Stephane) and as a bonus a Les 2 Boules Desunies.

Today something special again: I managed to create some first additional challenges for my Exchange puzzle Acrobat. More to follow from time to time.
Structural update on 2012-09-21
As you may have noticed, something happened to the puzzle category/classes on this page. After more or less dynamic growth of this gallery page with more and more puzzles, and after the introduction of sub pages in the grid views to manage the growing number of puzzles by the end of last year, I decided to give the web site a major overhaul. The main differences happened "under the hood", but there are two things that are visible: During the upgrade, it may have happened that a puzzle went into the wrong category by accident, or you may have some information to add -- please let me know. Now I hope that the viewing experience is enhanced by this update and the gallery is more fun to browse and a better source for reference.

Today some very nice burrs from Greg Benedetti arrived which he presented at IPP32: Blind Burr and Odd Repartition. The Blind Burr is a very unusual burr and was one of the top ten vote getters at IPP32 Design Competition.
Added on 2012-09-08
Currently, I am doing some research on those n-ary puzzles together with some other puzzlers. In the process, I have created a ternary puzzle prototype of a Bob Hearn design that has never been built before, it only existed in a paper on Bob's homepage. Using Lego bricks (and a bit of glue), and some stickers, I created a prototype version of Sliding-block "Chinese Rings" style puzzle. Now I can do pracitical research on this puzzle and since there a many small pieces involed, there are a lot of moves for a 3-ring ternary puzzle!
Added on 2012-08-21
Now that I have been back from IPP for some time, I have found the time to get all the Exchange puzzles into my gallery. As there are about 80 of them, I will not mention them here one by one, but have put them ona separate page of IPP32 Exchange puzzles
This is also to avoid putting them on this web page in an unstructured pile, similar to the one created from these puzzles on my living room table (see picture to the right).
IPP32 Exchange
Added on 2012-08-19
Last week I have been to a fabulous IPP32 and coming back, here are the first puzzles I brought with me. They are the puzzles I bought at the Puzzle Party, the puzzles from the Exchange are expected to come on-line in an additional update coming week -- there are just so many of them to be photographed, catalogued and eventually also solved.
From the Puzzle Party I brought a Design Competiton entry somewhat similar to the Quadlocks, but more complicated, as after removing the key pieces, the frame needs some more lock-picking moves to be taken apart: Burrblock. From Richard some nice tiny microcubology items: Coherence and Bolero; from Greg some of his designs with twists and turns, not from wood, but printed: Tronc Commun 4 and Doube Noeud. From Brian an IPP27 puzzle, a maze looking one-dimensional only at first sight: Straight Forward. From Abraham Jacob some nice binary puzzles (see n-ary puzzles) I have only heard of recently: Trio, Quartet, Quintet, and Sextet F&L puzzles. The last one was given as table puzzle at the Awards Banquet.

Today the third part of my order of nice Iwahiro coordinate motion puzzles arrived: Triangular Jam. These 5 two-dimensional coordinate motion puzzles (1,2,3,4,5). may lack the third dimension, but they are nevertheless fascinating puzzles. For somebody like me who is used to axis-parallel burr-like movements, they are a nice training for out-of-the-box-thinking. Thank you, Dirk, for pointing me to them!

Some of Wil's latest inventions arrived today: New Dovetail. It is a very nice addition to the well known Dovetail series of convex and concave dovetails, and collectors who already have both of these will like the new one. For Dovetail-professionals it features some new concept and classic solutions might not work, for all amateurs and beginners, there are some tricks to overcome. And then there is the majority of people who do not believe that such shapes can be disassembled at all, but believe me: it is possible! Maybe this is the nicest aspect of these puzzles: Let people guess how these objects were assembled and how they can be disassembled again.
Added on 2012-06-13
Today a small package arrived from Problemboden, Finland -- small, but containing some big puzzle business. The first puzzle in it seems to have something to do with ???, but it's not a detective story, but an n-ary puzzle: Mysterians, a 5-ary puzzle. Then there are two puzzles that look easy, but certainly are not (they are by Iwahiro, need I add more?): Rectangular Jam and Rightangular Jam. Then, there are some two Finnish puzzle boxes: Tricky Gift Box and Trick Box "Finland".
Added on 2012-06-07
An interesting package containing some of Alfons Eckman's latest works arrived. They are all of high craftmanship and very nice to play with. The property that none of these puzzles can satisfy is being easy -- luckily!
There are three new 18 pieces burrs in three different shapes: The Garuda is a traditional shape 18piece burr with a level close to a 100, and it seems to be part of the Phoenix familiy (first impression after trying about 80 moves), then the Waddon, which has wider pieces like the Phelan, and then a new type with entirely flat pieces: the level 29 Cephio.
Also in the package were: Triton (a hybrid burr), Cocoon (in some way similar to Padaung Rings), and Devil in Cage (only three pieces in a cage, but level 54).
Added on 2012-06-05
Today two packages were waiting for me at the customs office:
The first is from India and contains two beautiful and tricky vintage padlocks for my collection: Trick Lock with four keys and Trick Lock with three steps.
The second package also came from the east, but a little farer away from Hong Kong with state of the art twisty puzzles: Plum Flower Snake, Mixup Plus Cube (not at all standard 3x3x3), and some pillowed pentahedrons: 3 Layers Pentahedron, Crazy 3 Layers Pentahedron, and 5 Layers Pentahedron.

Update on 2012-04-23
Reworked yesterday's update on puzzle 1000. It turned out to be double-ternary instead of 6-ary, which is a completely new type of puzzle.
Added on 2012-04-22
Only a few hours before the German Cube Day (GCD) it arrived: The last puzzle to get a three digit number. It is a Bin Laden and it is as close to being number 1000 as it is as close to being a true binary puzzle. It was designed by Rik van Grol to seem like a binary puzzle at first, but to get you stuck in a dead end then. Only when you figure out that in fact it is a hybrid of binary and ternary puzzle, you can solve it. This is also the motivation for the "devilish" name. Bin Laden
Auf dem Holzweg
-=- 1000 -=-
This is the moment that readers of this web page (and myself) have been waiting for: My collection has crossed the 1000 boundary and puzzle numbers are four digits from now on.
I have been wondering which puzzle would get the honour to be the celebration puzzle, but when I found this puzzle on GCD yesterday, I had no doubt: I picked up an Auf dem Holzweg which seemed to be the first level-6-Kugellager to exist (or actually equivalent, but very, very close to a Kugellager). However, it turned out to be something new: A combination of two ternary puzzles (see yellow and green sections in the picture to the right), which I will now call "double-ternary". More details on this discovery are presented in my updated article.
Holzweg-Sections
After my research on n-ary puzzles (see Kugellager.pdf and the n-ary Puzzles Group page) it seems that his puzzle has deserved to be number 1000. If you do not believe me, have a look at the updates for puzzles 900 and 500 in the update history.
From the GCD I brought the following puzzles:
A vintage binary puzzle SPIN-OUT by Binary Arts. This and the other n-ary puzzles are on the now updated n-ary Puzzles Group page.
Closely related to the Towers of Hanoi is the Rudenko Disk. I met Theo Geerinck and got his Chainstitch. From Siebenstein are the Holzweg Puzzle above and: Diavolo, Safe, and Nur Mut, a tiny Burr. I met Willem van der Poel an got the first of one of his IPP exchange puzzles, a Combination Lock. Michel van Ipenburg brought me some of Oskar's interesting designs: a Planar Burr (as described in one of the Gathering for Gardner books) and a Domino Tower, accompanied by a Jeliku. For my cuboid collection, I also got a Twisty Puzzle: a 4x4x6.
Added on 2012-04-18
Just before GCD and a few days after finishing all those Burrs some new puzzles from Arteludes: A Pyramid, a nice Chateau d'If, and an Identity Matrix. Usually, in Mathematics, an identity matrix is something simple with a clear and simple structure. Here, we have a nice puzzle called Identity Matrix that is far from trivial: 24 identical notchable pieces that lead to an astonishing level of 13.8.

Today is Burr's day (no, not birthday, but with a similar feeling), and to let you know why, let's have a look at the latest update. Today I picked up three packets at three different locations (hooray, German post offices!) and got a whole load of nice Burrs:
  • From Maurice Vigouroux and Guillaume Largounez: an Abad's level 9 burr
  • From Alfons Eyckmans: A Condor, a Phoenix, a Phoenix-Cabracan, a Misery, and an Al Capone
  • From Jack Krijnen: A Century
Al capone Phoenix-Cabracan Phoenix Misery Condor Build a house Abad's Level 9 Burr Century
Since this a lot of puzzles and Jack knows that I already have some, he included a nice house for me to build and store all the puzzles in it. :)
Today I won't provide links from the puzzle name to the puzzle pages, but instead run a little quiz:

  1. Find out which puzzle is which in the picture to the right! To verify, just point with the mouse or click on the puzzles in the picture.
  2. Estimate: What is the sum of the moves to get all first pieces out of these burrs? Answer, click here (Needs Javascript).

A very nice surprise package from Alfons Eyckmans containing two very well crafted high level 18 pieces burrs, many thanks! The first is the well known Tiros, playing in the world's top league of burrs. The second one I have identified as Balder, a very interesting hybrid of regular 18 piece burr pieces and the ones with 2x3 base, known from the Phelan or Dirty Dozen. This definitely brings back some memories from recent solves of these two 16 and 18 piece burrs.

Added even later the same day: Today I finally started a feature on this site that was on my wishlist for long: Group pages. Starting with the most famous group for this page (I believe), I will add more groups occasionally, providing an overview of puzzles that may have something in common -- may it be obvious or not.

Just before Christmas I received my nice present from the Karakuri Club. Spoiler warning: If you are still waiting for yours and if it would be by Miyamoto, don't read on! I don't know the name of it and will update the gallery once I have received it. The puzzle looks a bit like one of these old fashioned Scales whose base has then been put in a box, but see for yourself: X-mas Present. It is not trivial, but I have managed to open it already. Now I have to figure out in detail how the mechanism and solution works.

Yesterday on the Dutch Cube Day in Eindhoven I met very many nice puzzle colleagues known and unknown to me, and of course very many puzzles old and new. A very exciting event, indeed! As usual there were Puzzles that I considered to be too expensive for my current collecting habits, but I managed to bring a whole bunch of puzzles I got from several people:
It started with my puzzle friend Bernhard who had some items I could not resist: By George Burr (a burr-like puzzle with several moves and a rotation), Triangle Cube Burr (quite simple, but nice cuts and woodworking), Dutch Cross (a Burr with a solution having an akward turn -- of 180 degrees), a Kei Cube Jr and a Puzzle 7.
TomZ had some interesting and complicated new designs -- and of course the one I had pre-ordered: Super-X
At Wil's table some pre-orders were waiting for me. Now I have the winner of this year's IPP design competition, a 4 Steps Visible Lock, which I already liked and solved during IPP -- of course I left the Euro coin inside for the next one :). At Wil's I also picked up: one of his Aluminum Cylinders, an unknown Framed 6 piece burr (looking like printed by George Miller), and the new Cast Donuts.
I also found some IPP exchange puzzles I did not have: Marcel Gillen had a Burrliner Kruse for sale and Rob Hegge a Five Burr-ito.
There were also some new production range puzzles from 2011 with a nice look and very high quality: Moeraki 4 and 3.
The others are a mixture of cheap vintage puzzles and some new puzzles: Plastic Chinese Rings, Metal Chinese Rings (yes, two additions to my n-ary department), Triple Cross, A Turnstile-Variant (for some insight on the "Triplex" puzzle), Frustr8tor, Calendar Barrel, Keyboard Cube, Dororinth orange and white, from Russia a traditional Screwed Shackle, an 8 Pice Burr, and a Rudenko Clips.

This week I was at Spiel 2011 in Essen and besides loads of Games and some puzzles, I also met some Puzzle-Friends there. When I got home, I received two additional packages, so many puzzles in today's update:
From HKNowStore: The Bermuda Cube series, all variants: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and House I, House II, Column, Star, and additionally some others: Circular Bean Tower, Bandaged Pyraminx, 3x3x3 3 slices, 2x2x2 Bandaged, and 1x2x2
In the package from Eric: Twist the Night Away -- it has many twists in the solution and I am tempted to put it into the Twisty category, but it is definitely a (Dis-) Assembly puzzle, and a very nice one!
From the "Spiel" fair: From Jean-Claude Constantin, some of his and some rare other puzzles: Kugellager 7 (as mentioned above), a Eivon (another kind of smartphone puzzle), and some IPP31 exchange puzzles: Crazy Bottles and Modern Times; and an original Roger Tap and Kamei Money Bank and a level 9 Six Piece Burr. New Twisty puzzles from Hendrik's shop: Spinner and Double Disk. From Rombol and Philos I got: Interlock 3 Pieces, Kaneko Cube, Money, and Polo Shirt Puzzle

An IPP31 Design Competition entry by Greg Benedetti: Daedalus. Here is a short review I promised to John Devost: :)
This nice puzzle was created in different wood versions and looks like a straight and simple rectilinear interlocking puzzle. But beware, it isn't. In the inside not only interlocking pieces can be found, but also grooves and wooden pins forming an internal only partly visible maze, a maze that evolves and changes with every move you make. Moves that were blocked just a moment ago, or only halfway possible, might be there now and you have to keep your track carefully -- or get lost in the maze.
If that wasn't enough already, rotations are not only possible but also allowed and part of the solution. Usually, rotations tend to lead to shortcuts in the intended solution. For this puzzle, the only solution is full of rotations and even then an astonishing 23 moves to remove the first piece are the result. Alltogether, 49 moves are required in the unique disassembly solution, with 9 moves for the second and 8 moves for the third piece. Burr-Tools will hate you when you try to solve this puzzle with the help of a computer. Luckily, for the faint hearted, there is a solution booklet included, which is of the nice high quality and craftmanship like the puzzle.
To my personal knowledge, this is the first puzzle design with this combination of elements, and a very interesting one. Anyone interested in high level burrs, but getting bored of more traditional ones, try this one (if you can get hold of one, of course)! Happy Puzzling!

I just came back from IPP31 and there was a package waiting for me: Always Empty Box
Maybe this always empty box could solve some space problems I might run into: IPP31 was great and I met many interesting and nice people there, played with very interesting puzzles and had numerous interesting conversations and lectures. Now I have to solve a packing puzzle consisting of over 30 more new puzzles and my already full shelves, after unpacking them, solving them and putting them into the gallery. It will take some time, so please stay tuned. Meanwhile, in the picture on the right you can see what I am facing at the moment. :) Update: I have eventually managed to put them up in the gallery, but as some of them are still unsolved, I will probably replace some pictures by the solved version some time in the future.
Gifts from IPP31 organizing committee: IPP31 puzzle gift, an Anchor Puzzle, and for the helpers a small Made in China.
From Bill Cutler: He had his very First Design remade as his exchange puzzle. He also carried some puzzles from Jerry McFarland for me: a Quadlock 1 and a Quadlock 4.
During the Puzzle Exchange, I had the honour and pleasure to be exchange assistant to Iwahiro. His exchange puzzle "is a box packing puzzle. Just four identical octahedrons, just put them in the box completely. Simple!". That's what he said.... Of course, "this is not a solution": Gem Box, but it is a very nice and well crafted puzzle.
Some of this IPPs exchange puzzles I got were: 6 piece burr variation II (Andreas Roever), Laby Box (Hendrik Haak), Houdinis Torture Cell (Brian Young), Reunification (Twins, Rob W. Jones), Brandenburg Gate (Marti Reis), Eighteen Eights (Peter Knoppers), and Boxed Mixed Piece Burr (Frans de Vreugd).
Some other puzzles I got: 3-piece Magic, Choreographed Motion, Arch Burr Puzzle, Dino Cylinder Cube, Buttonhole Puzzle, Four Sticks Dexterity, 3 Lives to Live, Five Sticks 28, 4 in 2, Little Tree Box, EQ 12 pieces burr, and an old design remade: William Strijbos' Aluminum Cross.
From the French puzzle Collector Jean Carle I got: Manda 1 Burr, Love's Dozen together with a cubic variation of the same puzzle, and a Pause.
From Gregory Benedetti I received three prototypes, all high level puzzles: Eccentricity, La Foudre, and Troacroas.
From Frans de Freugd I got some nice burr puzzles: Boxed L-burr #2, All Mixed Up, and a variation of this puzzle.
