Google’s doodle of a Rubik’s Cube has many reminiscing about the iconic puzzle toy, which was invented in 1974, but only got a worldwide release in 1980.

Hungarian architect Erno Rubik invented the colourful 3x3x3 cube in 1974, but it was not released globally until 1980, where it quickly gained popularity as a mass-market puzzle and later turned into a fashion accessory that defined the decade.
