Abstract: The block puzzle of the present invention includes a first set of eight pieces comprising a straight piece, an L-shaped piece, a square piece, a T-shaped piece, a Z-shaped piece, a center piece, a left-hand piece, and a right-hand piece. Each of the eight pieces comprise a combination of four cubic units, all of the cubic units being the same size. A second set of eight pieces identical to the first set can be combined with the first set, and the combined 16 pieces may be assembled into a plurality of configurations, all of which produce an overall cube having 64 of the cube units therein and having a length, width and height equal to four of the cube units. A modified form of the invention includes a set of 16 pieces which are flat and which include three straight pieces, three square pieces, three Z-shaped pieces, three L-shaped pieces, and four T-shaped pieces. Each of these 16 pieces are formed from four square flat units.
