There are about 43 quintillion (1018 or 1030 - depending on your nationality) ways to arrange a Rubik’s Cube, but only one that is correct. Since a Hungarian architecture professor named Erno Rubik invented the cube in 1974, more than 350 million cubes have been sold globally.​
Rubik, 76, often speaks about his invention as if it were his child. “I’m very close to the cube. The cube was growing up next to me and right now, it’s middle-aged, so I know a lot about it,” he said in a new interview.
