The Rubik’s Cube is the world’s best-selling toy, with over 300,000,000 original and imitations sold worldwide. It continues to make headlines as new records are broken and new versions appear.
Another Rubik’s cube puzzle is on its way: the Rubik’s Mirror Blocks puzzle. Each piece of this Rubik’s Cube has a mirrored surface and is a different size and shape than the one next to it. It is set to sell in Japan this year for about $20 USD.
