Ernő Rubik created the first prototype of the “Magic Cube” in 1974 in Budapest, Hungary. An American toy manufacturer bought the product license and renamed it the Rubik’s Cube in 1980, making the puzzle an international sensation. At the height of the toy’s popularity in the mid-1980s, the company estimates that as much as one-fifth of the world’s population had tried solving the Rubik’s Cube. With its eye-catching colors, affordability and the puzzle’s level of difficulty, the Rubik’s Cube has maintained popularity over the years.
