The solution is extremely creative and devious.This puzzle is shipped disssembledFor multiple items, combined shipping is available. Simply message me once you are fin...

Just four simple-seeming pieces to fit into each side of the tray, but they're much trickier than you'd think to get your head around, and there's only one solution per side!

Up for auction is HEPTAGON 40, a multi-challenge packing puzzle designed & made by Koshi Arai.

Designed and first released at IPP in 2009, Surround is closely related to the 3/4/5 cubes designs by Ichiro. In this case, six pieces must be used to surround the solid cube in such a way that is self-supporting. Two solutions using magnets are possible, with another "rule-breaker" solution that does not use magnets and covers the cube completely! The finished shape is pleasingly symmetrical and displays well.69 copies in made for sale, each signed and dated. 8 copies in Walnut & Maple, 11 copi...

Andreas' exchange at IPP38.  Assemble the snake of spheres into an octahedron

This puzzle was Henry Strout's exchange puzzle at IPP 29 in San Francisco. To solve the puzzle, all the pieces must be put in the box. Easy enough, except for two things. One, they must all go thorugh the 1x2 slot in the side, making the order of insertion quite important. Two, the yellowheart piece is stuck inside the box, so you have to plan around that. Quite tricky!
