#19: Rubik’s Cube (1974)
The Rubik’s Cube is another great example of simplicity equalling endurance. Designed to test a player’s problem-solving skills and dexterity, we think it’s safe to say that the Rubik’s Cube has become a cult favorite, beloved by both adults and children. I mean, can you think of another 3D puzzle that has anything remotely akin to the Rubik’s staying power? We certainly can’t.
