ABSTRACT:
A puzzle formed of a plurality of puzzle pieces which, when assembled, create a self-standing, three-dimensional building structure. The puzzle pieces are of irregular, polygonal shape, but all puzzle pieces are flat, planar blocks. The blocks are releasably interlocked about a common plane with first, edgewise, complementary dovetail joints. For interlocking puzzle walls that are transverse to one another, second, straight U-shape, edgewise, complementary tenon and mortise joints are further provided edgewisely of those corner blocks for frictional interlocking. Thus, no separate pin, bent units or the like are required to anchor the corner portions of the three dimensional structure. The self-standing, enclosing structure is continuous, and show a continuous image on its external face.
