10 Fast records to solving the Rubik's Cube
Speedcubing (or speedsolving) is the practice of trying to solve a Rubik's Cube in the shortest time possible. There are a number of speedcubing competitions that take place around the world.

The first world championship organised by the Guinness Book of World Records was held in Munich on March 13, 1981. All Cubes were moved 40 times and lubricated with petroleum jelly. The official winner, with a record of 38 seconds, was Jury Froeschl, born in Munich. The first international world championship was held in Budapest on June 5, 1982, and was won by Minh Thai, a Vietnamese student from Los Angeles, with a time of 22.95 seconds.

Since 2003, the winner of a competition is determined by taking the average time of the middle three of five attempts. However, the single best time of all tries is also recorded. The World Cube Association maintains a history of world records. In 2004, the WCA made it mandatory to use a special timing device called a Stackmat timer.

1. Single time:
The current world record for single time on a 3×3×3 Rubik's Cube was set by Mats Valk of the Netherlands in March 2013 with a time of 5.55 seconds at the Zonhoven Open in Belgium.

2. Average time:
The world record for average time per solve was set by Feliks Zemdegs at the Melbourne Cube Day 2013, with a 6.54 second average solve time.

Note about Rubik's Cube:
The Rubik's Cube, a 1974 invention of Ernő Rubik of Hungary, fascinated people around the globe and became one of the most popular games in America in the early 1980s, having been initially released as the Magic Cube in Hungary in late 1977, and then re-manufactured and released in the western world as Rubik's Cube in 1980. As of January 2009 350 million cubes have sold worldwide making it the world's top-selling puzzle game. It earned a place as a permanent exhibit in New York’s Museum of Modern Art and entered the Oxford English Dictionary in 1982. The Cube retains a dedicated following, with almost 40,000 entries on YouTube featuring tutorials and video clips of quick solutions.
