Spotted Cube interlocking puzzledesigned, crafted, and exchanged at IPP32 by Ken Ewerssize: 7cmadditional info: high quality build, simple and fun assembly

Designed and made by Hidekuni Tamura.This little cube has a lot more to offer than meets the eye. The internal structure is very well thought through and assembling the pieces without instructions can be a huge challenge. The puzzle completely surprised me, it's a fantastic challenge.

Leontev's 205 Minutes is a masterpiece in both design and construction. So named because if you make one correct move per second, non stop, it will take you 205 minutes to disassemble. This n-ary juggernaut requires over 12 thousand moves to disassemble. Once disassembled, a reset mechanism allows you to quickly bring it to the original state with only four moves. It also comes with the 136 minute piece which only requires around 8,000 moves to solve.It was a difficult decision to make this puzz...

William Ja has knocked the ball out of the park with his first design. The cheekily named "Triorchidism" was inspired by our earlier "Box with Two Balls." William expanded the idea by increasing the playing area to a 3x3 space and adding the third sphere to create a more complex and difficult challenge.The goal of Triorchidism is to remove all three marbles from the box. Confounding this is four wood pieces trapped inside. Moving the pieces and marbles creates an ever-changing hybrid interlockin...

One of Stewart's earlier works, Pyracube is a puzzle I've always wanted in my collection. I figured since I was going to make one, my customers might want one too. So here it is! Stewart has this to say about Pyracube:Pyracube introduces a large family of puzzles made by joining polyhedral blocks together different ways, in this case by using edge beveled cubes (or to put it another way, truncated rhombic dodecahedrons). Strange as it may seem, they pack snugly and neatly into the cubic box with...
