A '''polycube''' is a solid figure formed by joining one or more equal [[cube (geometry)|cubes]] face to face.   Polycubes are the three-dimensional analogues of the planar [[polyomino]]es.  The [[Soma cube]], the [[Bedlam cube]], the [[Diabolical cube]], the [[Slothouber–Graatsma puzzle]], and the [[Conway puzzle]] are examples of [[packing problem]]s based on polycubes.<ref>[http://mathworld.wolfram.com/Polycube.html Weisstein, Eric W.
