Patent ID: 7140612

Claim:
An assembly puzzle comprising: a three-dimensional, symmetrical figure consisting of interfitting assembly pieces and a support base; the support base comprising a shape equivalent to: a flat, horizontally-oriented, polygonal bottom member possessing an upper surface and edges; the upper surface being divisible into a whole number of identically-sized, edge-connected squares; the upper surface having an area; at least one vertical tower having a height; the tower being facially attached to at least one upper surface square; at least four vertically-oriented side walls having top, bottom, and side edges; the side edges of adjacent side walls contacting one another; the bottom edges of the side walls contacting the bottom member; the side walls being divisible into a whole number of identically-sized, edge-connected squares; the assembly pieces and vertical tower having a shape equivalent to a whole number of identically-sized, facially-connected cubes; the symmetrical figure being at least two cubes in thickness; the volume of the symmetrical figure being defined by the area of the upper surface multiplied by the height of the side walls; and the shape of the symmetrical figure conforming to the shape of the support base and the height of the side walls.
