Abstract
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. The 16 pieces may be arranged to provide a two-dimensional square having 64 of the identically mentioned square units formed into an 8×8 square. Each of the different shaped pieces in both of the above configurations may be made of distinctive colors so that different color patterns may be obtained when the pieces are put together into different configurations.
