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 inte...
A modular unit for use in a three dimensional, self-standing, continuous puzzle structure, consisting of a planar, polygonal block defining first and second, opposite, main, flat faces, and a peripheral edge joining said first and second faces orthogonally relative thereto, at least one of said first and second faces forming an image destined to face externally of said puzzle structure; said block edge comprising: (a) first, dovetail joint means, for releasably anchoring complementary dovetail joint means of a second block edgewisely of the first-mention...
