In 1974, Hungarian professor Erno Rubik invented a cube to teach students about 3D space. Soon, the Rubik’s Cube became popular worldwide for its difficult puzzle.
By the late 1970s, Rubik patented it, and it became a global hit. The 3×3 Rubik’s Cube has 43 quintillion possible ways to arrange its colored squares, and solving it became a competition. Today’s record for solving the Cube is just over three seconds. For many people, it is a fun challenge and a way to work with their hands away from screens.
The Rubik’s Cube sold hundreds of millions of units, and people continue to enjoy solving it. Rubik believes the Cube will stay popular for at least 50 more years.
