Rubik's Cube

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. Check out the section on speed cubing here.
Every legal permutation of the Rubik’s Cube can be solved in 20 moves or fewer.
The Rubik’s Cube was first called the Magic cube but was renamed in 1980 for its global release.
