Abstract
An amusing puzzle made up of a plurality of cube-shaped pieces, which form a unitary cube when the puzzle is properly solved. Each puzzle piece contains at least one permanent two-pole magnet which, when the puzzle is properly solved, is attracted to the corresponding pole of the magnet contained within the adjoining puzzle piece, thereby holding the puzzle pieces together in order to form the unitary cube.
