Whole Description

Model Name: SQ12

12 three-dimensional polygons fashioned out of heavy oak, which are stored in a felt-bottomed oak frame. The enclosed booklet challenges solvers to use these pieces–which resemble anything from a plus sign to the letter L–to replicate the 54 designs and patterns shown on its pages, things like a 3-D pyramid and a 2-D rectangle.
