Abstract
A multiple piece puzzle comprises a solid sphere with the external appearance of a golf ball of modern construction. A series of curving cuts through the sphere separate the sphere into a plurality of separate pieces wherein the cuts form complementary pairs of surfaces among the separate pieces. Proper assembly of the pieces solves the puzzle and restores the golf ball appearance of the puzzle. The curving cuts form interlocks between the pairs of complementary surfaces whereby, once assembled, the sphere will be retained together in three dimensions in a similar manner as two-dimensional puzzle pieces are retained together. In the preferred embodiment, the puzzle comprises eight pieces that can slide together, however, the puzzle can be formed with more pieces for added complexity and more challenge.
