Dovetail Burr is our follow-up to the Japanese Wood Joint puzzle we released last month. Both are part of the series that Frans designed nearly 20 years ago. Inspired by traditional Japanese woodworking joinery techniques, Dovetail Burr was Frans's IPP 20 Exchange puzzle. Dovetail Burr remains an utterly unique interlocking board burr concept despite its age. The presence of matched dovetail joints forces each pair of pieces on a given axis to interact with the other. This innovation creates a ...

Clamp is a very fun puzzle. When Tim originally sent it to me I didn't see the brilliance. After thinking about it I made up a prototype and immediately knew I wanted to offer it to my collectors. For such a simple assembly, it's surprisingly tricky to take apart! Sliding the halves back and forth and hearing the satisfying click of the magnets as they align the box is addicting. Careful or you'll never put this one down... Construction of this puzzle is outstanding! Very precise movement with a...

The excellent 4L puzzle is back by popular demand! This is one of my favorite puzzles. 4L was awarded an Honorable Mention at IPP 2015 and is FAR trickier than it looks. The goal is to pack the four L shaped pieces into a very simple box. There are two different types of L pieces (fat and thin) and several possible configurations. The solution is extremely creative and devious.This is the first of two oddball copies of 4L we will offer in this event. We have one additional oddball in this wood v...

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 allow the inner burr to move smoot...

Small Box Two (Aha Box) was Allan Boardman's IPP exchange puzzle in 2004. Allan describes it as "designed to lure your non-puzzler friends into "our" world." Seemingly solid and impenetrable, Aha Box gives very few clues upon handling. A solution does exist, and it's quite tricky to discover. Sturdy, pocket-sized, and with a surprising amount of useful space inside, Aha Box is a great puzzle to share with friends and non-puzzlers. The construction of Aha Box puzzle is exact, with a solid fit and...

ResQ is a unique Sequential Discovery Puzzle based on Boucher's brilliant Visitor Q. We took the original design and modified it by adding additional goals, tools, and tricks. ResQ is the result of nearly three months of prototyping and features previously unseen concepts and hardware.The brilliance of Boucher's VQ design is in the depth of possible movements and states the puzzle can be in. Visitor Q is very much like a maze; you find configurations that won't allow you to progress and must bac...

Daedalus by Gregory Benedetti is an utterly unique masterpiece of design. Brilliantly creative and brutally tricky, Daedalus hides its secrets well. The beautiful exterior gives no clue to the sheer pandemonium hiding inside. What appears to be a simple cube is an interlocking maze that continually changes its state with rotations, dead ends, and deception. Simple disassembly is a challenge; reassembly is genuinely an accomplishment. Daedalus is difficult to make. Each puzzle contains pieces fro...

Very well crafted wooden checkerboard dissection puzzle from circa 2004 with over fifty 2D and 3D checkered challenges.  The unit cube is 2cm size, so this is not a tiny puzzle.  The company did not stay afloat and as far a I know, the builder, Andrew Snowie no longer makes puzzles.  Portable box includes a snap together tray for playing.  Great for travel.  Fun for the whole family. USA shipping: $15 (USPS Priority).   International shipping will be calculated after auction, but will N...
