Competitions and record times

Many speedcubing competitions have been held to determine who can solve the Rubik's Cube in the shortest time. The number of contests are going up every year; there were 72 official competitions from 2003-2006, of which 33 were in 2006 alone.

The first world championship organized by the Guinness Book of World Records was held in Munich on March 13, 1981. All cubes were moved 40 times and rubbed with petroleum jelly. 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 22.93 seconds.

Since 2003, competitions are decided by the best average (middle three of 5 attempts); but 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.

The current world records for both average and single timings were set in 2007:

• Average time: Yu Jeong-Min of Korea set an average of 11.76 seconds, on January 7, 2007, at the KCRC Championship in Seoul, South Korea, a significant gain on the earlier record of 13.22 seconds by Anssi Vanhala of Finland in Svekub 2006 (March).

• Single time: Erik Akkersdijk of The Netherlads set the best time of 9.77 seconds in the finals of the Dutch Open 2007 held on October 13/14, overtaking the previous best time of 9.86 seconds set by Thibaut Jacquinot of France set at the Spanish Open a few months earlier. Interestingly, in the final of the Dutch Open, Erik was edged out by Joël van Noort by 1.11 seconds on average time, though he still has the Dutch average record of 13.17 seconds average set at Czech Open 2007.

Many individuals have recorded shorter times, but these records are not accepted due to possible lack of compliance with standards.
