Geneva is the first new puzzle by William Hu in quite some time. Named after the clockwork mechanism that it's partially inspired by, the level 9.3.4 solution includes some very unique rotations and coordinate motions. During assembly, there's a fair amount of freedom, with a lot of dead ends to run into and circles to run around in. Geneva is a nice addition to any TIC collection.************************************************************For multiple items, combined shipping is available. Simp...

The Pin Cubes series by William Hu are three new cubes based on a 3x3x3 structure. By including drilled holes and pins, each puzzle in the set takes advantage of this format in a different way and creates three very different experiences.  Designed to be tricky in both disassembly as well as assembly, they are a new take on an old idea, and well worth a look. Pinprick (Goncalo Alves) is the middle difficulty and takes advantage of its form to include an unusual step that will amuse any solver ...

The Pin Cubes series by William Hu are three new cubes based on a 3x3x3 structure. By including drilled holes and pins, each puzzle in the set takes advantage of this format in a different way and creates three very different experiences.  Designed to be tricky in both disassembly as well as assembly, they are a new take on an old idea, and well worth a look. Pinball (Walnut) is the most difficult. Pinball is quite unusual; there is clearly a single movement that wants to happen, but it is sto...

Are you ready? No. You're not ready. This puzzle is a BEAST.Puzzler's Cage was designed by Junichi Yananose in 1999 without the aid of a computer. He describes it as “crazy hard”. The puzzle has more interlock than should be possible, with half of the stick ends captive in notched perpendicular pieces. Even with instructions, assembly is a daunting task.We used three different woods to give clues for solving. The beautiful tones of Bubinga, Schedua and Black Palm ensure this will hold a priz...

The puzzle is a set similar to the Penultimate Burr with multiple problems to be solved. The set consists of a 4×4×4 cage with a 2×2 opening on each face and 14 non-planar penta/tetracubes. The objective is to fill the cage with four of the pentacubes and three tetracubes to complete a 4×4 cube. A jig is provided for testing possible solutions outside the cage, as well as a box which doubles as a display plinth for the solved puzzle. This is a difficult puzzle, with two assemblies having a ...

Double Slideways is a brilliant design and I'm glad we found time to make it again! This is a re-release of Ray's excellent exchange puzzle we last produced in 2014. The exchange edition was in a smaller format and fully notched for production efficiency. This remake is in a larger size and features augmented construction with a triangular stock insert. As a result, there is less void space once assembled, giving this edition smoother operation and more stability in the solved state.We used a ve...

The goal of Fano Blocks is to pack seven pairs of identical rectangular pieces flush into the box. These aren't just any pieces, however! They possess unique properties: any two distinct blocks share precisely one edge length in common and any set of two specific edge lengths are held by two identical blocks. The resulting number of edge-matching combinations creates a complicated problem. Finding even one of the eight possible solutions is an accomplishment.Named after the Fano plane (the small...

Tenchi is a brilliant anti-gravity packing puzzle named after a Japanese word that translates to both "Sky" and "Land," the goal is to pack the pieces into the frame so that the puzzle can be lifted and rotated without any part falling out.There are over four thousand possible assemblies, but only one unique assembly locks the pieces. While challenging, Tenchi is not impossible; analysis and experimentation provide enough insight that you may find the solution using critical thought.We used nine...

This second release of Lift Box incorporates a couple of design improvements over the last version. Customer reviews of the previous release describe the box well:"Removing the lid of the Lift Box is easy, but this does not allow to access the inside of the box and here the actual solve starts. The box has an unusual mechanism, and first time I have seen one like that. There are some carefully hidden hints in the design that give you a rough idea what may be required, but actually finding the mo...

Confetti Box was designed to cap off 2019, a great year which saw us make more puzzle boxes than we ever have before. It's festive, it's surprising, it's abrupt! This box went through several prototypes and redesigns, and I'm quite happy with the final result. The operation is a new concept for me and I'm eager to see how much of a challenge it proves to be.************************************************************For multiple items, combined shipping is available. Simply message me once you a...

The "TV Puzzle" is a long-discontinued Pelikan release that was the subject of particular obsession on the Mechanical Puzzle Discord. I somehow got roped into making it; I'm still not sure how. Those guys are persuasive.TV Puzzle is an interesting hybrid packing and take-apart puzzle. My interpretation stayed true to Jakub's original design with a couple of changes - we fully lacquered and changed grain direction for all pieces to make the solution more difficult. The result is trickier than I e...

The Bamboozler from Serhiy Grabarchuk (Bits and Pieces)Twelve small bunches of bamboo pieces need to be put together in the stand to make a bundle of bamboo pipes.  This puzzle was surprisingly difficult.  It’s probably (unintentionally) a dexterity puzzle too… it was not easy to keep the pieces stable in the stand.  I’ve enjoyed a couple other puzzles from Grabarchuk but this one was tough.  The photos are careful to avoid any possible spoilers.The wood puzzle is in great conditi...

Lighthouse by Doug Haigh (Bits and Pieces)Doug Haigh’s recreation from Hoffmann’s classic book.  Object is to free the brass ring (or the lens/gem).I’m selling a few of these older, discontinued metal Bits and Pieces take apart or sequential discovery puzzles.  Lighthouse is my favorite of these… it’s a nice “starter” SD puzzle, on par with the brass cannon.  It’s also a nice metal puzzle for display, and it was fun to experience this “classic” puzzle.I was able to...
