Rubik's Cube

The Rubik's Cube is a 3D combination puzzle invented in 1974 by Hungarian architect Ernő Rubik. Initially called the 'Magic Cube,' it was patented in Hungary in 1975. The puzzle gained international popularity in the 1980s and has since become one of the best-selling puzzles worldwide. In 2020, the Canadian company Spin Master acquired the Rubik's brand, continuing its legacy of innovation in the toy industry. (smithsonianmag.com)
