<p>A manipulative puzzle is provided comprising eight interconnected pieces in a 2 x 2 x 2 cube and having three orthogonal planes in which groups of four pieces can be rotated to exchange relative positions The puzzle comprises a body and a piece supported by the body in fixed position relative thereto. Seven support plates are carried by the body and have the outline of spherical triangles occupying an octant of a circle with gaps between the plates adjacent the division planes for piece rotation. Seven pieces moveable relative to said body are slideably supported on the support plates and connected thereto by hook formations at their vertices that fit into the gaps and locate behind the plates.</p> |
