<p>PROBLEM TO BE SOLVED: To provide a three-dimensional puzzle where a plurality of different complete bodies can be assembled selectively by all of a set of blocks.SOLUTION: Provided are three-dimensional puzzles comprising a plurality of blocks, namely the three-dimensional puzzles where a plurality of parallelepipeds 401, 402 in that a first parallelepiped 10 and a second parallelepiped 40 are divided into parts can be assembled selectively by all of the plurality of blocks. In this case, the first parallelepiped 10 and the second parallelepiped 40 are mutually subjected to isochoric deformation so that the surface of either parallelepiped is hidden inside the other parallelepiped.</p> |
