Abstract
A magnetic toy or puzzle comprising a plurality of essentially two-dimensional pieces that may be assembled to form a hollow three-dimensional object. Each piece has at least three edges, and a magnet is mounted along each edge of each piece to allow the edges of the pieces to be joined together. The magnets are preferably keyed to allow: (a) only certain edges to attach to each other; or (b) the edges of the pieces to fit together in only one orientation. The magnets allow the edges to be joined in certain configurations to obtain the three-dimensional object. A holder for the puzzle pieces is provided that adds additional puzzle possibilities.
