ABSTRACT:
A puzzle that provides for rearranging different pieces to form a pattern formed from the pieces is disclosed. The puzzle includes at least one generally trilateral piece having three sides, and at least one generally quadrilateral piece. At least two of the sides of the quadrilateral piece have been adapted for engaging the friction enhancing surface on the trilateral piece, so that by surrounding the fixed hub with the trilateral pieces that are separated by the quadrilateral pieces, a continuous round gear surface is formed, that can be used to rotate the trilateral and the quadrilateral pieces together.
