The Rubik's Tower (or 2x2x4 Rubik's Cube) is an interesting twist on the original Rubik's Cube. Imagine two 2x2 Rubik's Cubes that rotate around the central axis allowing this puzzle to shape-shift. That's right - it makes it very difficult to solve! Be sure the rows are correctly aligned before turning the Rubik's Tower and never use excessive force.
