Siamese Twins was the exchange puzzle of Markku Vesala at IPP25 in Finland, 2005.The goal of this disentanglement puzzle is to separate the two nearly identical (like Siamese twins) parts, and to entangle them back to the start position.While verifying the puzzle, I noticed the puzzle was not in the official start position when the pictures were taken. The position in the pictures is slightly more challenging as a start position (in my opinion), but the puzzle will be shipped in the start posit...

Marble Cake from the Karakuri "cake series" puzzles. This is a small, beautifully made puzzle box with a simple trick opening mechanism.

I have had this tucked away in storage for so long I had forgotten about it. Struggled to find any details of it online.Obviously the goal is to remove the sword from the stone.

The goal is to remove the pieces from the frame and then replace them. A maze is created by the surface pieces, making this a difficult puzzle to solve.

The shapes are all the ways four cubes can be stacked together. In essence there are 7 different puzzles.This puzzle was dreamed up by George Miller. However, Prof. Donald Knuth was the person who analyzed the problem an...

This puzzle looks just like another caged burr at first glance. It's only after playing with it that the genius of the design is apparent. Four identical pieces dance around two longer horizontal pieces to create a unique level 18 solution. Not only do you need to determine the position but orientation becomes important as well.

This large version of the classic Parcel Post puzzle is beautifully made by master craftsman John Devost - this is an excellent puzzle for a coffee table or living room!Pack 18 pieces into the frame; only three pairs of pieces are identical, making this quite a challenge.Three-page Solution and computer analysis from Bill Cutler included.I need to reluctantly sell some pieces from my collection to replenish puzzle funds; all puzzles are kept in a pet-free room at 68 - 73 F, and 45% - 50% humidit...

While thi is a simple 4x4 cube (no rotations even!), this design steps up the difficulty to the next level. It really is an amazing puzzle, with a unique level 14.8 solution (!!!!) which on top of being high level, has some very unintuitive and tricky movements.

Secret Burr is a re-release of a puzzle I made very limited copies of in 2002. Unique in that it's difficult in both assembly and disassembly, there are two locks inside the burr that interact much like Cutler's Ball Bearing Burr. Instead of steel bearings, Secret Burr uses small wood rectangles. Precision crafted of fine hardwoods, this puzzle not only looks exotic, but has the trickiness to back up its appearance.************************************************************For multiple items, c...
