The new Rubik’s cube may look simple without the colors, but the Mirror Block has 9 different sizes of blocks on each face. Solve it with different patterns and it will turn it into an irregular shape. Those who can do the original cube at breakneck speed will jump at the change to challenge themselves with the new puzzle for ~$20.00, while those who still have yet to master it might want to hold off until your more talented friends are done and will lend you one.
