Rubiks

The Rubik’s Cube was invented in 1974 by Erno Rubik; he wanted a working model to help explain three-dimensional geometry. It took him one month before he was able to solve the Cube for himself. Over 350 million Rubik’s Cubes have been sold worldwide – making it the bestselling toy of all time. The best speed cubers (people who take part in speed cubing – a sport where competitors try and solve the cube as quickly as possible) can solve the cube in under 6 seconds.
