The Rubik's Cube is one of those puzzles that amaze people. It is still not clear whether knowing how to solve the cube makes you cool or a complete nerd. Either way, it is still a great party trick to pull out a Rubik's Cube and solve it.
Rubik's Cube was released in 1980, and within one year it had become the fastest selling puzzle the world has ever known. Over 250 million Rubik's cubes have been sold worldwide. It was invented by Erno Rubik, a Hungarian Professor of Architecture and Design. The initial interest in the cube for Erno was not about designing the world's biggest selling toy but about the technical aspect of producing a working 3 dimensional cube. Initially he tried building the cube using rubber bands but that failed. His final design let the individual blocks hold themselves together by their shape. Once Erno had a working cube, he soon realised that after only a few moves, the colours of the cube were mixed up and that it was not an easy task to re-align them. At first Erno wondered if it would even be possible to solve the cube. He worked on the puzzle and after one month he had devised a solution and the rest is history.
