A puzzle device similar to that sold under the registered trademark RUBIK'S CUBE includes a hub with six orthogonally related square sockets, six mutually spaced circular retainers having inner and outer faces lying in spherical planes spaced from and concentric with the hub and coupled to respective sockets by square shanks, seven triangular slide members slidably underlying and bridging adjacent retainers and having outwardly projecting triangular shanks, an interlocking member having three ribs each of which is anchored in one of the recesses in the retainer, and three tongues each of which releasably engages recesses formed in the slide member peripheries and face members connected to the triangular shanks and having outside faces forming a regular three dimensional figure when the slide, retainer and interlocking member is in interlocked condition. The face members may have many different shapes, for example square, triangular, flattened spherical quadrants and form respectively different configurations. The slide member supported face members are rotatable in groups of four about selected orthogonally related axes.
