One of the world's most beloved puzzle games turns 40 this year and its invention was actually an accident.
Google paid homage to the Rubik's Cube by making an interactive Google Doodle on their home page.
The Rubik's Cube was created in 1974 by Hungarian architect Erno Rubik as a way to explain 3D geometry. He did not realize he created a puzzle until he mixed it up and tried to put it back together. He patented it in 1975, calling it the "Magic Cube." Over 350 million Rubik's Cubes have been sold since its inception.
Although it is often synonymous with the 1980s, professional competitors around the globe still take part in races to solve the puzzle as fast as possible. There are all sorts of world records related to it.
The current world record for the fastest single time of a 3 x 3 x 3 cube was set in March 2013 by Mats Valk of the Netherlands. He solved it in just 5.55 seconds at the Zonhoven Open in Belgium.
There are also world records for solving it blindfolded, with just one hand as well as with...feet!
