The Grooved Three Piece Burr by Kouki Kusumi won an honorable mention in the 2020 IPP Design Competition. This fascinating assembly has three identical pieces yet only one solution. Despite their similarity, the pieces interact uniquely to assemble into the traditional board burr shape. With a level 8.2 solution, this puzzle is approachable yet fun for all experience levels.************************************************************These puzzles are extras and oddballs that have accumulated in ...

This is a really nice construction of this classic puzzle. I’ve solved it just a couple times. And for most of this puzzles life, it has been been stored away in airtight containers. 

See CD site for full description. 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 stabi...

See CD site for full description. BurrBon is an utterly unique Interlocking Burr Puzzle. What could be better than a six-piece burr? How about a six-piece burr inside another six-piece burr? There are several ways to build the inner and out burrs separately, but only one possible configuration assembles them together. The interaction between inner and outer pieces is what makes this an extraordinarily difficult puzzle.The construction of BurrBon required just the right balance of tolerances to ...

This collaboration is one I've been looking forward to for a while. Darryl designed this excellent 12 piece set, with pieces precision machined in either brass or aluminum by Bryan and contained inside a precision-crafted box by Fuller. Darryl describes the burr set below:  "In the 1970s, Bill Cutler published a complete summary of the solid 6-piece burrs that could be formed from "notchable" pieces. He presented a set of 42 pieces that would make all 314 solid, notchable puzzles. I wanted a s...

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 ex...

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 stopp...

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...

This padlock shaped five-piece caged interlocking burr will perplex you with its level 13 solution. The previous lock shaped burrs we have made included a key-shaped piece; the unique interplay and accessibility of simple burr pieces make this latest offering from Tim an interesting change.************************************************************For multiple items, combined shipping is available.

Rupture by Alexander Magyarics is a tricky space-filling puzzle. While adding the pieces into the box is not too difficult, the proper solution requires you to fill the openings completely. No gaps are allowed, and no rotations are necessary. With a unique level 6.6.3 solution, this is easier said than done!************************************************************For multiple items, combined shipping is available.

Spy is an Interlocking Puzzle with a secret. Four Purpleheart and Yellowheart pieces packed into a Figured Maple container...simple, right? Perhaps a closer look is in order. With a level 24.2.2.2.4 solution, Spy is definitely hiding something! Even disassembly is a difficult task.With sturdy shouldered box construction and burr pieces milled from solid exotic wood, Spy looks great when disassembled and even better when solved. Tolerances allow for smooth movement while ensuring a stable final a...

Uri Three Bars is an unusual and beautiful interlocking puzzle. This will be our second batch after an earlier, very limited release in 2015.
