Rubik's Cube Tower
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. Its shape distorting capability makes cubing that much more challenging. Do you think you will be able to match the colors back again?
