The Rubik’s Cube is 40 years-old today and to celebrate, Google has created a Google doodle that presents an interactive virtual version of the much-loved puzzle toy.
Erno Rubik invented the 3x3x3 cube in the spring of 1974, although it wasn’t released globally until 1980. The Hungarian architect hand-crafted the prototype and set about trying to find the solution, which could take a lifetime if each element was just rotated randomly.
It took him a month and he realized that this could be a clever puzzle for the mass-market. And by January 2009, more than 350 million Rubik’s Cubes were sold worldwide. More recent figures are not available, but considering that was more than five years ago, you can bet that figure has risen significantly.
