The Rubik's Cube

In the time since its international launch in 1980 an estimated 350 million Rubik’s Cubes have been sold. Approximately one in seven people alive have played with a Rubik’s Cube. The beauty of the Rubik’s Cube is that when you look at a scrambled one, you know exactly what you need to do without instruction. Yet without instruction it is almost impossible to solve, making it one of the most infuriating and engaging inventions ever conceived.

Are you up to the challenge?
