Erno Rubik needed a month to solve his own cube. 🧩

Erno Rubik needed a month to solve his own cube. 🧩 . . . In 1974, the 29-year-old Budapest architecture teacher built the first prototype from wood blocks, paper clips and rubber bands to show his students 3D geometry. When he twisted it, he realized he had no idea how to put it back. It took him over a month of trial and error. Over 450 million have since sold.
