With the advent of the Internet, finding solutions to the Rubik's Cube are aplenty, but here's a new twist to the classic puzzle - the Rubik's Mirror Blocks Puzzle. As you can tell by its name, this variant complicates things by making each block slightly different in size. Instead of getting all six colors on their respective sides, you will find it challenging to figure the whole thing out no thanks to a mirrored surface. This puzzle will head towards Japan for approximately $20, and there is no word on a North American release as at press time. Perhaps you could pick this up at an import store or soemthing if you're a hardcore puzzle buff.
