Each of the nine pieces that form this puzzle are assembled of small cubes or parts of a cube. The object is to get them back into a 3x3x3 checkered cube. The workmanship is especially good, with each of the pieces having beveled edges on all sides. The base is rather unique with its four legs. The sides of the base have Plexiglas panels to keep the parts in place and to better view the cube. This is one of our most attractive puzzles.
