It?s also called the Hungarian Horror, but is better known as the Rubik?s Cube, named as it is after Erno Rubik, the Hungarian sculptor and professor. He invented the puzzle in 1974 and it became popular in a few years. Books were published on how to solve it and one, written by a 12-year-old British schoolboy, sold over 1.5 million copies. TV programmes and cartoon shows were done on it. The cube can show billions of combinations, but the funny thing is that it can be solved within 29 moves.
