A three dimensional twisty puzzle is usually made of a set of pieces that can
change their position through a group of operations, obtaining different combinations. Physically, the rearrangement of positions is done through the rotation (twist) of some pieces around a point of the polyhedron (which
may represent one of the pieces of the puzzle), which is usually located at the center of a face or a corner.
Often the puzzle pieces have one or more colors and the solved state is represented by the position in which each face of the polyhedron contains pieces of a single color.
