The CalmPlex puzzle is a wooden logic puzzle constructed of 2-cm (3/4") cubes,  which makes a 6" by 6"   8 by 8 checkerboard and a 3" by 3" by 3"  4 by 4 by 4 cube. The puzzle also can make more than 50 other shapes.

This 3” sphere puzzle, created from 12 wooden pieces, comes with its own custom display stand.

The object of this puzzle is to assemble the 13 wooden pieces into a 3” tall pyramid shape.

Like its “big brother,” the Pocket CalmPlex puzzle is a wooden logic puzzle. It's constructed of 1cm (3/8") cubes, which can be manipulated to make a  3" by  3" 8 by 8 checkerboard, a 1.5" by 1.5" by 1.5" cube, and more than 50 other shapes.  And it’s portable.

It will take young builders five to 25 minutes to fit the eight pieces together to form a football. The included stand can be used to aid in the assembly and to keep it from falling apart. It even looks nice on office desks of Monday morning quarterbacks.
