This is a set of 27 interlocking Cubes arranged in a 3x3x3 cube shape.  The puzzle challenges the player to transform the arrangement of the 27 cubes from one shape to any other shape, without disengaging any of the Cubes from each other. Cubes must be shifted by sliding along their faces.  The Cubes can shift in all three dimensions: X, Y and Z, but each face slides in only one direction. There are many solutions because there are millions of shapes you can tranform from and to.  The ultimate goal is to be able to logically understand how to shift from one shape to another in the fewest number of moves.  Other games can be invented by disengaging the Cubes and re-engaging them with the colors "flipped" on one or some of the Cubes, creating a "marked" Cube. The challenge is then to shift the "marked" Cube or Cubes into a specific position in the arrangement
