Interesting Fact: Invented in 1974 by Hungarian sculptor and architecture professor Erno Rubik, the Rubik’s cube has challenged and frustrated countless numbers of players who have ever picked up the 3-D toy puzzle. While the Rubik’s Cube reached its peak popularity in the 1980s, the more than 350 million cubes sold since then make it one of the best-selling toys of all time.
