quintillion possible combinations. Now imagine you have no websites, no books and no one to show you how to solve it, because you invented it. But you didn’t invent the Rubik’s Cube. (enchanting music) This guy did. It was 1974. Thirty-year-old Erno Rubik was just beginning his career in academia. Once the physical cube was put together, Erno began hunting for its secrets. Erno racked his brain for a strategy, twisting and turning the cube in his hands and his head to unlock his creation. And after a month, he cracked the code. (turning cube) But the story doesn’t end there. In 1980, Erno would finally bring his cube to the world. And from there, it took off, becoming one of the best selling toys of all time. And after almost 40 years, Rubik’s Cube has seen a comeback, with hundreds of competitions every year across the world. For Erno, the cube that bears his name is more than just a toy: it’s a reminder to never give up.
