Diniar designed a variety of different puzzles, and among them are some where you had to stack some discs in a way so that their common cutout form a certain shape, and this type of puzzle dates back to older designs from many years ago. The title for the following puzzle hints what that its shape should be: Symmetric Shape. Here the four octagonal discs with the regular n-gon cutouts should be stacked so that you can see a symmetric shape. The puzzle comes in a nice 3D printed box and when stacking the golden discs into the box, the dark blue background makes it easy to see the current shape arranged. As the cutouts are not placed in a symmetric manner, each disc has 16 different orientations (half of them by flipping the disc over). One of the discs seems to be symmetric, though. Disregarding the bottom one, this amounts to a whole 2048 different possibilities to try — or use a more systematic approach! So far I have been unsuccessful solving the puzzle, and this does not really seem the puzzle type for me. But it I like how it is nicely made in a box with decorations.

Today's puzzle addition is one from Diniar, and it is a predecessor of the Gears go! and in some way a prototype for that one: Dinilock 4. It is one in Diniar's lock series that all resemble padlocks and of which so far only the first one has been published. The Dinilock 4 has the same disc mechanism like the Gears go! and the goal is to rotate the discs in a way such that they no longer interact with the blockers in the frame side, and the middle slider can be slid out. It also comes with some additional pieces that allow for reconfiguration and with these a different arrangement of discs can be set up and there is also another frame piece that has a different configuration of blockers. A fun puzzle to play with, but like Diniar also mentioned: It is quite easy, as there is not a lot of space to set up complicated challenges. Comparing with the Gears go! one can see that that one has a bigger grid and more possibilities for frame reconfiguration, which allows many interesting challenges, more than in Dinilock 4.

The current pandemic situation restricts many busineses, and among them the escape rooms. The German escape room company Escapewelt started developing an escape room in a box that you could solve at home alone or with your friends, and it is basically a puzzle box coming with some clues on the box to be deciphered. The shape is that of an ancient pyramid, hence the name: Escape Pyramide. It comes in a nice packaging and arrived quickly (within Germany) after ordering. The clues are hidden all over (and beneath) the pyramid and give you the required information to open the combination locks included in this puzzle box. Overall, it took me around 30 minutes, and was a fun experience. There seems to be a help site on-line, but I have never visited that one, and instead I retrieved the prize from the pyramid: A small puzzle with a (German only) quote on it. This is the second escape room in a box I have, and I like both a lot, while they are completely different when it comes to shape and solution. A nice high quality puzzle to play with on an afternoon at home (for example) and for a very affordable price! While the instructions come in both English and German, this seems to be mainly aimed at the German market at the moment.

After a first puzzle of this kind earlier, today's update shows the second in this series of highly symmetrical puzzles: Senemmetry II. Of course, the picture only shows the pieces and not the solution, and again there is a shape to construct with 6 symmetries to be found. This one seems to be a bit easier than the first, and it also has less pieces than the first.

Today's puzzle is a recent auction win, and an entry of both the IPP39 Design Competition and Exchange: Escape From The Bastille. Originally this was planned as an Exchange for the IPP in Paris, where I also had a Bastille themed puzzle. The puzzle features an internal maze and one (or more) steel balls, which repesent the inmates and guards of the prison, and goal is to maneuver the steel ball in the oubliette (the dungeon) to the window labelled with "Liberté". On the way, has to find a key and navigate down a spiral staircase and a secret passage. Through the windows, there is some limited visibility of the maze, and there is also a reset feature, but this could also lead to an early end of the escape!

My last June update features a puzzle by Diniar and theme wise it may be something for a hot summer day: Cool your Cocktail. The orange box resembles a cocktail glass filled up to the top, something red inside — maybe resembling a drink with strawberries? Then there is a single ice cube to be put inside. That ice is not really a cube, but oddly shaped and looks more like an irregular crystal. Not hard to imagine that it will be difficult to put it in. The red top of the box consists of three rotatable lids, and after figuring out the possible orientation of the ice cube, you then have to rotate the discs to make the hole the right shape and size for the iceberg to drop in completely. The solution I found looks like it should be unique and there is no space to spare and the block of ice slides in nicely without having to melt part of it first. Of course, getting it out is close to impossible, and then the quick reset feature comes into play, which allows you to remove the ice from the (now cooled) cocktail and set it up for the next victim. Of course, this disassembly is only to be used for reset, not for pulling out the discs and testing them separately against the cube to make things easier! A nice and very well themed puzzle, and definitely not too easy!

Today's addition has been on my web site for a long time, even though I never owned one and only played with the puzzle at a friend's place. It is one from the compendium, and after a recent auction win, I am now able to put it to this main page and the n-ary puzzle group. The puzzle is an Exchange puzzle from an early IPP: A Slide-Ly Tricky Tower. It looks like Tower of Hanoi implemented as a sliding puzzle, and it comes in a nice packaging showing the London tower bridge with 3 towers (instead of the usual 2). The basic shape reminds me of both Tower of Hanoi and the Panex puzzle. Compared to the Panex puzzle, there is only half the pieces, but an additional tunnel below the towers that can be used to slide blocks between the outer two towers, while the middle tower position can be blocked during the solution. There red blockers coming in different sizes which can be used to restrict the tunnel to only some size range of the blue pieces, so that the larger blocks cannot use the tunnel any more. The two extremes are equivalent to some well known puzzle: Without blocking pieces, this is like a Tower of Hanoi (obeying the rules, of course!). With all blocking pieces added, it is like a one tower Panex. A nice puzzle and auction find! Operation is excellent with the three orange rings to move the discs precisely.

With my recent order with MINE, there came also another puzzle I am putting on this site today: I won the lottery and like it seems typical for Japanese lotteries, things got more expensive and I could spend some more money for another puzzle: CASSOWARY. It is one of those cute acrylic coin traps with a lot going on inside. First, I thought it was just a bigger version of the early version I already have, but in fact, it is not only bigger, but also has more pieces, more steps, and a nice new coin from Papua New Guinea to be extracted. While the puzzle has the perfect size to put it into the pocket for bringing it to puzzle meetings, it came in a bigger and fascinating packaging, which shows the puzzle levitating in the middle and has some resemblance with Lego bricks. A nice puzzle and not too difficult.

Diniar has re-used a mechanism of one of his puzzle locks in a puzzle box, and the result is: Choc Box. This one has a lid with three interlocking pieces that need to be removed to slide out the lid. After accomplishing this, and opening the lid (and a second lid below), a packging puzzle appears. 11 identical pieces assume the role of "chocolates" in this Choc Box and can easily be extracted from the box. As they are inedible, it is best to put these "cocolates" back into the box, and that is where the packing challenge starts. Those pieces based on a triangular prism grid only go back into the box in one configuration, and having done that, closing the lid and locking it for the next puzzler is the rest of the challenge. A nice multiple challenge puzzle, with different challenges of a puzzle box and a packing puzzle. At the moment, I am not sure which one is the more difficult one, but for me at least it is the packing puzzle, as I am not very good at them! A cute box puzzle coming with some extra challenges! The box is very well made in a sturdy fashion using a 3D printer. Once you have solved everything, all the pieces are contained in this box (but not before!).

From MINE I received a package with some of the latest crazy packing puzzles included. The first three are from IPP39, and that includes some award winning puzzles in the Design Competition: 4L Basket won big time, with two of the top prizes, and I am happy that I can now play with it instead of the earlier solving attempts only in my mind without a physical copy to verify. Like the other puzzles from this package, it is very well made and fun to play with, and a certain German puzzle friend may be interested to hear that I solved it within my usual 15 minutes deadline (after having forgotten about all the virtual attempts from last year!). I am not giving anything away by telling that this will need rotations to put all the 4 L pieces into the basket. What I liked about this one may also be explaining part of the success at IPP: Nicely built, an easy to understand challenge, and with some analysis and trying it is possible to solve it within a good amount of time, and with some insights what works and what does not. This is also the only one I have solved already, the others are yet to be solved: The Tetra Spinner was also in the competition and looks a bit strange as a packing puzzle. A 2D frame to pack the tetrominoes in, but then there are two lids fastened to the frame with a movable screw in the middle. At the beginning, you can move the top/bottom lid arrangement aside to insert pieces, but the more you pack into it, the less space you have for both maneuvering the pieces and the lids, which makes it increasingly difficult to insert the colourful pieces. The Legal Packing is the only of the bunch that actually comes with the pieces packed into the frame. Here, a quote from a Japanese puzzle friend I was allowed to assist during his IPP Exchange many years ago describes the situation well: "But this is not a solution!" Indeed, these pieces need to be packed into the frame without bending, and the current configuration requires exactly this when removing/inserting some of the pieces. The other two puzzles come with two challenges each: Packing Puzzle 4P has 4 nice dark blue P pieces (hence the name) and the frame has two sides for the two challenges. For a moment, I thought the second challenge might be to easy, but it turned out that I was too "clever" and had overlooked something, back to square one! The last one, called POCKET, has a different arrangement: One frame, with a slot on the side to enter pieces, and two different sets of pieces. While the blue pieces look easy and regular, the others look a bit more chaotic, but maybe they will give more hints on the actual solution in the end, who knows? These are nice puzzles, and maybe because of their Japanese origin, they have low space consumption, which is a good aspect for collecting, too! Stay safe out there and keep on puzzling, and all best wishes to puzzle friends currently impacted by the current pandemic!

A puzzle from Diniar from last year's IPP, which was used as an Exchange puzzle: Five Ducklings. This is a tray packing puzzle, coming in a nice 3D printed version that even features a lid so you don't loose pieces when transporting the puzzle. There are 5 ducklings, one of them a bit bigger than the other 4. At the beginning, 4 of them sit in the bigger pool, while the last one has its own little pool. Goal is to pack them all into the bigger pool (in a 2D arrangement). The puzzle is fun to play with and while I am not good at packing puzzles, I found a solution within half an hour or so.

A brand new puzzle by Diniar is a puzzle box: Gears, go!. It comes nicely decorated and 3D printed in stylish black with some ornaments on the sides, and some red disc pieces on top. To open the lid, the circle puzzle needs to be solved — while also sliding the lid out (or possibly back and forth in between). The lid is blocked by interaction between circle pieces and the black blocker pieces sitting in the box frame. Once opened, other challenges with other configurations of red disc pieces and blocker stones can be configured, and for this the puzzle comes with many extra pieces and additional challenges. Actually, most of the challenges are still in development, but a variety of difficulty levels seems to be possible. The puzzle is very well designed and made, and fun to play with. It is also used as a storage space, and there is no space left any more. All the additional pieces nicely fit inside. That makes perfect sense of course: To set up additional challenges with the additional parts, you will need to solve and open the current one anyway.

A nice sliding piece puzzle from Diniar, which is also an IPP Design Competition entry: Moon and Star. At first sight, only seven quadratic pieces in a tray, some of them with a second white layer on top, depicting a crescent moon and a star. At closer sight, there is much more to it and this seemingly trivial puzzle is much more interesting: While most of the moon shapes are cut so that their borders are aligned to the blue square pieces beneath, this is not the case for the top part, and that sticking out part soon starts interacting with the other white parts and starts blocking moves. Well, interacting with allmost all parts — as we all know the moon and stars are at very different distance from earth, so those won't block each other and just pass. The first challenge is to move the star two fields up, next to the moon, while maintaining the rest of the layout. Having done that, there are 4 more challenges, and it is a good idea to just continue solving those. First of all, because it is a nice puzzle and feels like you should continue, secondly because the goal position of each challenge is the same like the starting configuration of the next, so you can simply "run" through them without any additional setup moves. The puzzle is a lot of fun to play with and not too difficult, but requires some insight and strategy for the solution. It also comes in a nice tray that can be used as a lid, keeping everything secure when stowed away. A fun multiple challenge puzzle for an afternoon!

Lego puzzle boxes are becoming ever more popular these days and there are several designers with Youtube channels showing their designs. These boxes have the big advantage that when you have the building instructions and piece list, you can get all the pieces yourself and build such a puzzlebox for yourself, and also modify it if you like. Of course, there are some rules: Disassembling the puzzle boxes by removing lego bricks (or other pieces stuck to the box) is not allowed, and some designers will allow you to remove exactly one piece as a tool. In my collection there are now two of these boxes: Mouse House is quite easy and has some discovery elements. Only 5 steps, but multiple tools are involved in the solution! When it opens, there is a prize inside, that can be heard rattling all the time, and the color reminds me of some cheese, fitting the name of the box! The The Yule Box has typical Christmas colours (hence the name of the box!) and requires 9 steps to find a crystal inside. The mechanism is taking up a lot of space, so there is not much room for the compartment and it is only a small crystal. Box boxes are fun to solve, and the Yule Box is a bit more difficult than the Mouse House.

Diniar likes to create designs from various different classes of puzzles. Today a simple looking one, a symmetry puzzle: Symmetric Shape. There are some edges of the same length which immediately led to some assumptions, and this puzzle is playing with these assumptions. To avoid any spoilers, no further details are described here, just worth mentioning that it is a nice and not very difficult puzzle that plays with your expactations. After solving I put the pieces aside, and shortly after, I tried to reproduce the shape and failed. So this puzzle also has some replay value! A good puzzle to try even after a work day in the evening.

The next one from Diniar is an Exchange puzzle from IPP35: H Slider. I picked this one next because it reminds me of the "My Tower of Hanoi", which was a fun puzzle. And indeed, there seem to be some similarities in how the solutions work, and the H Slider seems to be a bit easier to me. When solving the first challenge, I had some nice insights how a systematic solution can work, and could then extend this to solutions for the other challenges. The first challenge is to interchange the red and orange pieces. The other challenges have different starting configurations, and the goal configuration is always the same like the start of the first: red number sequence left, orange right. This is a great idea, as you don't have to remember any goal configurations, but just set up the new challenge and start playing until you reach the known configuration. I made my way through all provided challenges quickly, and then tried to solve some random ones, by shuffling them and then putting them into the frame in random order. It seems that unlike for the 15 puzzle, here all challenges can be solved. A fun puzzle, giving you some not too difficult entertainment for an afternoon, and indeed I did enjoy this one!

A new puzzle from Diniar: Whirling Wheelies. This is based on the classic 15 piece sliding puzzle, and adds another layer. On most of the white sliding pieces, there are some red disc pieces mounted so that they can rotate. They are discs with one, two, three segments cut out, and these segments allow interaction with neighboring pieces. The blue piece is a bit heigher than the white ones and interacts both with the white sliding blocks and the red discs, and the goal is to maneuver this blue piece to the corner marked with the same colour. As a pure sliding piece puzzle, this would be trivial, but the discs add another layer (sic!) of challenge to it, making it a fascinating new puzzle. Like for others of Diniars puzzles, the frame can be opened, and this is not only for a quick reset feature, but also for using some of the additional pieces that come with it (an additional solid white block, and several of each of the disc types). That way, some other challenges can be configured for playing, which is a really nice touch and gives you even more puzzling fun! 3D printed in high quality, this puzzle is nice to play with, and in particular I like those disc interactions while moving the white blocks. Those discs are not only able to rotate during some sliding moves, it also seems to be part of the solution!

From Diniar, I received an expansion of his Sliding Tetris puzzle, the Sliding Tetris Hardcore Expansion — thank you! This adds 10 more pieces to the set to a total of now 25 pieces. Challenges with these pieces can be built into the box for now 125 challenges with up to 46 moves to get the ball out. To solve these challenges, the pieces need to be slid around, making way for the ball to move in this dynamic maze, and to reach the goal position which is the square opening big enough to allow the ball to leave the box. If you are more a friend of packing puzzles, then you may like the additional packing problems. close to 30 different target shapes are provided, most of them to be assembled outside of the box (because they are much bigger than the 3x3x3 box), and each of them coming with several sets of pieces to be selected for this. Overall, many packing problems to be solved, and some quick counting gives a number of around 235 challenges in total. It seems that this is an ideal puzzle for the current pandemic situation and isolation, just in case you want to spend your time solving many challenges of a puzzle, and they can of course be played from easy to challenging difficulty.

From the latest Cubicdissection offering: a box with a funny name: Where's my Hammer. Maybe a hammer is not the best tool to open it, but I playing with it a bit, I have already found some other "tools" in the box — if they are tools, and I cannot tell yet. Tilting the box, it makes some interesting clicking noises, so something is going on inside. A beautifully crafted puzzle!

After travelling quite some time from Florida to Germany, today a puzzle from a colleague and friend landed in my mailbox today: Swiss Cheese Puzzle. It is a tray packing puzzle where you have to arrange the four pieces of cheese in a way that also the mouse will fit into the square tray. Funny idea! Why would one pack a mouse and a cheese into a square box, but of course we all know how it works with mice and cheese! Only five pieces, and a mouse that will fit into the hole created by the half-holes in two adjacent pieces of cheese, should not be difficult? Well, when solving this puzzle, there is a nice Aha! moment that made me laugh out. I am not going to write any more, not to spoil the solution! A nice puzzle and very well made, I like it. Thank you!

On Star Wars day a parcel with two boxes from Japan arrived, with two beautiful boxes with the theme "five": 5 times 5 times 5 is an extension of Iwahara's x-mas present and therefore in compendium and n-ary puzzle group. This time, the 6 panels move in one sequence, while in the previous one, the sequence was split into two groups of 3 panels. The Assymetric Cube -5- continues Kawashima's series of Bar cubes, and this box has some really nice Aha! moment.

From my friend Diniar I received a package with some of his latest puzzles and also some older, yet still fascinating ones. While the current ones are created using some modern 3D printers, earlier models (like some of my IPP Exchange puzzles) were created using acrylic sheets and a laser cutter. Unlike my usual process of putting the puzzles all onto my web page here as soon as they arrive, I will put these puzzles up one by one, and after I had the chance to play with each of them a bit. The first one is maybe one of the oldest designs, from 1935, and a take on the classic 14-15 puzzle: Dustin. This puzzle has 7 peanut shaped pieces of two circles (AKA numbers) combined, and a single 15 circle piece. Unlike a regular sliding piece puzzle with pieces of length more than 1 and with a 1x1 gap, where most moves are blocked, this puzzle allows many moves by also rotating some pieces while sliding them. Pieces can slide around corner here and this changes their orientation between horizontally and vertically, and two such turns may even turn the numbers upside down for the piece. The goal is to find a sequence of sliding moves from the starting configuration shown to the usual one, running from 1 to 15 line by line. I have already tried it a couple of times and ways, and the fascinating thing is that for me always one piece ends up upside-down (i.e. two numbers swapped) at the end. Looking at some permutations/transpositions and their sign/parity it looks like this should indeed be a possible challenge for a regular 14-15 puzzle, but these peanut pieces add another layer of complexity. Hordern's book also lists this puzzle and says there are several different solution, but does not list a solution, so I should keep on trying!
Update: Solved! It was a nice and interesting solving experience and a trick seems to be required for the solution.

Last weekend and this weekend, there would have been two nice puzzle meetings, which are not possible at the moment for obvious reasons. Instead of visiting them and buying puzzles there, I have now puzzles coming to me instead: From Pelikanpuzzles some of the latest puzzle gems that will soon be available from them (some of them already available!): Euklid For Kids is a nice packing puzzle of three blocks and a box with a restricted opening, and one idea behind the design was that I should take more than 15 minutes to solve this one. I received a prototype from Dr. Volker Latussek to try, and recently I picked it up and solved it within 15 minutes. BUT before that, for a long time I was not able to solve it and was quite confused what should be wrong with the puzzle (or me?) and I was convinced that these pieces would not fit into the box. I even took some measurements to confirm. Good that I proved myself wrong recently, and this production run version is of course much more beautiful with those nice colourful woods! From the last run of puzzles, I ordered a Pincers, which is not shown in the solved configuration here. Everything needs to be inside the box, nothing sticking out. A similar scheme is the base of the following 3 by Osanori Yamamoto, where all pieces need to be inside their boxes, and also cover the holes completely, showing a cube shape inside: Pumpkin 1, Triple 3, and Triangle Cube 3. The last one has some nice contrasting woods and is a new design from Belgium, from Lucie Powels: Rota #. I am curious to see if this name has anything to do with the solution. Of couse the # part refers to the target figure to build. Skipping the Cube Day, I also took a look for some new Constantin boxes, and at the Knobelbox web shop I found them and received them in their usual very fast way: Flohcircus probably has most parts of the solution going on on the lid, but the bottom has also an interesting feature and you can see from the picture that it just wont stand upright. I must admit that I mainly bought the Piano Box for the looks and topic, but then it also turns out to have a nice solution, and I won't mention more here to avoid any spoilers. When I first saw the Polaris Cube, I was wondering what kind of puzzle this is. Turns out it may be a "evil" relative of the Skewb, a Skewb that does not want to perform Skweb moves in the cubic configuration and with some extra edge triangles. Actually, there is a Skewb with extra edge triangles I have been playing with a lot, the Twins Cube, but they work a bit differently than on this one here. Time for some famous last words, like this one being easy to solve?

From Sweden a small but heavy envelope arrived, containing one of the latest trick locks, just released last week: Her Key to the Treasure. The story is related to the Titan's Treasure Puzzle Lock by the same designer, and the presentation is great: It comes with a nice 3D printed stand to be assembled and to show the picture of Titan's wife, searching for the key in her "purse". The purse is a little Abloy lock with an unusual key, and of course the lock has been modified, so it will not open with the key only. I have already found some steps and a tool, but I guess that there will be more steps to be found until the key to the treasure is to be found. A great lock puzzle, and I am looking forward to solve it!

Today a parcel with some nice new puzzles arrived from Puzzle Corner: After Puzzle Box 05 and 06, now the missing Puzzle-Box 04 in this series was available, and it comes with two wooden keys on a rope. Of course, one main question is whether these keys are part of the solution. Having solved the box already, I will not disclose the answer to this question, just mention that this box has a surprising new mechanism and is fun to solve. The second puzzle for today is one of Keith Winegar's sequential discovery puzzles with jigsaw puzzle piece shapes: Paper Clip. Not overly diffiult, but a nice puzzle to solve. The third one is roughly based on the Astrolabacus puzzle: Bananacus. Playing with some 3D printed prototypes at DCD, now I can play with a production version of this sliding ball puzzle.

Today two beautiful wooden puzzles arrived: The first one containing a level 16 burr from a new craftsman: Premiere — the name tells it, it is Terry's first build, but then it is a bit misleading because he has been designing puzzles before, which were built by others. Now Terry has started building his own puzzles, and I was lucky to win a draw to buy one of these puzzles (like in the famous Japanese puzzlebox lottery, where winning costs you a lot of money and gives you nice puzzle boxes in return!). This first build is a beautiful one with great craftsmanship. A six piece burr in a strangely shaped frame, looks like this will be fun to solve, and at that level, it should be doable.
The second one arrived in the afternoon, and for that one, I had the chance to play with one before at DCD, and immediately knew I wanted to have one: Phoenix Family. This is a burr set for experts, or should I say "extreme puzzlers"? Unlike other burr sets to build 6 piece burrs, this is one for building many of the highest level standard 18 pieces burr currently in existence, and it contains the world record holder Supernova, and some other named ones like Burrly Sane for Extreme Puzzlers, Tiros. Jack has beautifully crafted this set and a nice storage/presentation box, which also contains overview cards for six named burrs and six unnamed burrs, all of these of level 134 and above. Again, the name of this puzzle is a bit misleading, as the original Phoenix burr is not included, but a note telling how this puzzle started it all. The lid of the box contains a beautiful phoenix inlay, so there is a phoenix involved indeed! Of course, only the selection of pieces is listed on the cards, and not the long solution sequences. For me, building these burrs from this information only and without help would prove an impossible task, but using Burr-Tools for the assembly and then trying to disassemble them is difficult enough. Just yesterday, I revisited the BSfEP and even those 152 moves to remove the first piece of this known puzzle are a good challenge and offer some training for what is to come with this set. Jack has built this beautiful set in a nice size, and it is only roughly double the size of the Premiere (and that includes the box), so this is also a very space efficient way to play with high level 18 pieces burrs. This will take me busy for quite some time, I am sure about that! This burr set has 45 pieces, not only 18, but certainly deserves a space (if not several of them) in the 18 pieces burrs group.

Diniar sent me his latest invention, the Blindbox. This box completely made from 3D printed parts, in two nice contrasting colours, and features one dark frame, one central box with a lid (the actual box to be opened!), four lower maze sliders, and five upper maze sliders. Three of the upper maze sliders come mounted to the slider holders, while the four lower ones embrace the central box and interact with the upper maze sliders, a bit in a way like in the award winning Mazeburr-L. There are two extra upper sliders, and then also some extra challenges that can be configured. Goal is to run through the maze and extract everything from the frame, while the upper sliders interact with the lower sliders, and the lower sliders are restricted in their movement by the central box. A fascinating concept! The box arrives in a challenge with 25 moves for solving this one, and this is also also the maximal number of moves in the challenge set, difficult challenge to be solved first! Only after that, the box can be opened and reconfigured with a different challenge. Aside from the restrictions imposed by the central box moving together with the lower sliders, another aspect makes this puzzle challenging: Part of the maze is hidden inside the frame, hence the name of the box. A nice puzzle box, if you ask me, and very well designed!

After the puzzle with many moves (including resetting the puzzle yesterday), today a puzzle of about the same size arrived and with around 14989 moves less, but each move / step being much more complicated by its own. It is a heavy puzzle and has a great, solid appearance: Popplock T12. The latest one of the Popplock series is a bit smaller than the legendary T11, and again with a key (this time one solid piece), but no visible keyhole. I am looking forward to solve this one, and I will take my time to enjoy the solving experience, and I guess it will take some time and headscratching anyway!

The parcel the post man brought today caused a lot of work: Aleksandr did it again and after the Black Bow-Tie, he created another cylindrical puzzle based on an existing n-ary puzzle and taking the number of moves to a crazy yet playable level. After the slightly more than 13000 for the former, this one is only one move short of 15000: Vertical. As you can see from the pictures in the compendium entry, I took the challenge to run through the whole sequence to disassemble it. From the beginning on, the pieces move nice and easily, which allows for quite a pace when solving the puzzle. The sequence is systematic and when putting the puzzle down for a break (which you will need!), it is quite easy to determine which should be the next move. Of course, there is still enough opportunity to be confused and run into the wrong direction for some moves, but in the end, this is a puzzle, and it should have some challenge to be solved! A great puzzle, high quality in 3D print, and I enjoyed running through the sequence, and also like the colour scheme. More info can be found in compendium and n-ary puzzle group.
Now it is time to re-assemble, but I think I will save this experience for another day, as 14999 moves (and some more) ought to be enough for one day!

The first March update is no new puzzle, but about solving one. Another interesting excursion took me to the Burr Zoo group page, trying to find some spiders hidden in a block of wood.

An update on February 29th is something special. This date only occurs every 4 years, and then there has to be something to be added to this gallery on this date. Seems I had a Feb 29 update before, in 2012, but that was the correction of a name, so today the first puzzle update with new puzzles on leap day. The puzzles added today travelled half around the world and are from the inventor of the framed 6 board burr (with two groups of 3 pieces). This time, we have three puzzles with two pairs of pieces each: Pinned Framed Burr S, Pinned Framed Burr M, and Pinned Framed Burr L. The pieces were made a bit more complex than one would expect from the outside, with the help of Juno's CNC Router. Each of the pieces has one or two pins and a maze, and puts these puzzles somewhere onto the border between maze and burr puzzles. Craftsmanship and movement is excellent and the pieces move easily. At the high number of moves for the first piece, a lot of chance to get lost inside these mazes quickly! There are some instructions coming with the puzzle, but they will not help you when lost in the maze, but seem to be aimed at the consumption and entertainment of the customs office, describing in detail what to do with the puzzles. The only downside is that these puzzles have sold out already, but that does not affect my playing with it, does it?

From the US another puzzle arrived which is not available in the European market yet: True Challenge. Under a different name, this one won a Jury Honorable Mention award at IPP38 and is a puzzle with a new concept. On one hand, a twisty puzzle, where colored segments in two rings can be rotated around the equator of the puzzle and a half turn of the whole puzzle along an orthogonal plane is possible. The objective is to solve these colored segments, but in a way that all the magnets of adjacent segments attract each other, like shown in the picture. Three magnets are embedded into each segment and they produce some nice clicking sounds when turning the segments pushes them outwards and inwards again. A clever design idea!

After finding a star in the Mindanao last week, it is now time for the first snow (star crystals) this winter. Not outside, of course, it is too warm here, but imported from Plaza Japan: Cast Snow. This is the latest of the famous Hanayama Cast series, and this time it is an easier one than the ones before, and a beautiful one! While this has just been released to the market in Japan, it will take a few more months for the regular world wide release. Solving the puzzle is a fun experience and consistent with the 2 star difficulty rating. While not being too difficult, don't expect the puzzle to be trivial, there are still some twists in the solution (literally) to be found!

The latest of the fascinating pocket sized puzzles from the Philippines arrived today: Mindanao. It has a black and dark brown colour scheme, and it is slightly bigger than the others, but still pocket size. This one came without the usual sticky tape securing pieces from falling out, so I am guessing there are no such pieces that will come out easily or by accident. Not a lot can be seen from the outside, just a hexagonal white window, and a strange hole on the back side. However, tilting the puzzle is something that may lead to the first insight, and in my case it did. Soon afterwards it turned into a sequential discovery puzzle, and I can only guess how this mechanism is implemented. It has mulitple steps, and several interacting elements. Without completing I returned the puzzle to its original state for later examination, and to see if I can understand what may be going on inside, but then I was surprised to see that the strange hole on the back has changed its appearance. Seems I did not return the puzzle to its original state after all. From what I have seen and found so far, it is a great puzzle with some nice new ideas, some Aha! moments, and I am curious to see what else I will find. Not too quick, to enjoy the solving process a bit longer! Of course the screws and nuts are off-limits for solving the puzzle, but knowing the others that should be self-explanatory. A fascinating addition to the series, and I am curious to see what I will find in this puzzle and how the series will continue!

No new puzzle today, but an extension of the Burr Zoo group page, about an excursion to solve a whale related puzzle.

When looking at the IPP38 Nob Yoshigahara Design Competition, one entry was puzzling me. A shiny metal puzzle, looking very well engineered and a bit in the style of Wil's usual big boxes. However, knowing Wil, I was not aware that he had released a new design without telling anybody, and the inscription "J. Keegan" hinted that there must be a new designer in the puzzle scene. When it had become available and after hearing some positive feedback, I went to join the waiting list, and today a big shipping box arrived, and in it a nice wooden box, containing the: Jewel Thief. The puzzle comes with an instruction card made out of anodized metal and some additional extras, including a stand for the Lego Jewel Thief, to display her once she has been freed from her prison. The puzzle itself is also solid and massive, and seems to be as well made as the images would suggest. I am curious to give it a go, and it will be interesting, because it also includes some form of riddle solving. Seems like an escape room aspect. Probably this will take some time to solve, so let's put it to the backlog list — but more to the top of the list of puzzles to be solved, so the Jewel Thief is freed soon.

In recent years, Volker Latussek became famous for his packing puzzle designs, and also published some puzzles where one had to match highlighted sections of wooden blocks while packing. In today's update, there is a Design Competition Entry having some similar constraints, to arrange pieces while matching parts of them: Mesh. Here, the matching parts are press studs and their sockets, and the goal is to arrange the puzzle into a 4x4 grid and closing all the 16 studs — not like shown in the picture, can you find the mismatches? After some initial trying of 15 minutes, I have made some interesting observations already, but without solving the puzzle. That will take a bit longer, I guess, and involve more analysis. A nicely made puzzle and fun to play with.

On the way home, I could today pick up Juno's latest sequential discovery puzzle box, sent from the Pluredro shop directly to me: Ring Case. It is a cute beauty and the size is very friendly for collectors as well. The description on the web shop said that this may be something to befriend partners suffering from your puzzle collection activities, but after solving part of it, I strongly advise against using this box to propose. That may end up in a desaster! Removing the lid involves some nice sequential discovery steps, but then .... The ring inside looks expensive, even though it has no opal in it, but that is not the problem here. Like some other ring bearing boxes, there is a different challenge. Well, you get the idea! From comments I read from other puzzlers, I am not the only one looking to solve this challenge. This box is very well crafted and at the moment there still seem to be some available in the shop.

First parcel of the year came from Hong Kong, directly from Meffert's, with a new golden puzzle: Golden Dodecahedron. This one is based on the Skewb mechanism, like the Golden Cube by Tony. While the overall structure and shape make look like a Skewb mod with triangles and squares, it is still a confusing puzzle. There is a nice click mechanism, but when the pieces click into place, that does not mean that the puzzle is in a solved state, or even close. Actually for one of the rotating axes, clicking into place means that the puzzle is definitely not solved. A consequence of this is also that you have to be very careful when picking up the solved puzzle — grabbing the wrong layers and the puzzle will rotate easily and escape your grip. What I like best about this puzzle is the nice solid feel, and the looks: There are cuts that look like you could turn the puzzle, just to notice that these cuts slightly change direction from piece to piece and will not allow any turn in this configuration at all.
Just noticing that the names of the Karakuri x-mas presents have been published, these have now been added to this site and one of them also went into compendium and n-ary puzzle group.
