  • Puzzles forming platonic solids
    Patent number: 4676507
    Abstract: A three-dimensional puzzle in the shape of a Platonic solid is formed by six identical pieces. The puzzle can be in the form of a tetrahedron, a cube, an octahedron, a dodecahedron, or an icosahedron. Each puzzle has six identically shaped, three-dimensional pieces which interlock to form the solid and retain the pieces in their relative positions. Although the pieces of each puzzle are identical, the pieces of the different puzzles are differently shaped.
