Rubik's Color Blocks puzzle is comprised of different shaped pieces, rather than cubelets of the same size. These different shaped and sized pieces make the puzzle even more challenging when it's scrambled. You can also twist and turn the puzzle to achieve some incredible looking sculptures. To solve, you'll need to properly align all six sides by color and shape. For ages 8 and up. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
