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.

A speedcubing championship organised by the Guinness Book of World Records was held in [[Munich]] on 13 March 1981.<ref name="gwr1983">{{Cite book |title=Guinness Book of Records |publisher=Guinness Publishing |year=1983 |isbn=9780851122519 |editor-last=McWhirter |editor-first=Norris |page=85 |chapter=Cubism |chapter-url=https://books.google.com/books?id=WqUxAQAAIAAJ&q=%22rubik%22}}</ref> The contest used standardised scrambling and fixed inspection times, and the winners were Ronald Brinkmann and Jury Fröschl with times of 38.0 seconds.<ref name="gwr1983" /> The first world championship was the [[1982 World Rubik's Cube Championship]] held in [[Budapest]] on 5 June 1982, which was won by [[Minh Thai]], a Vietnamese student from Los Angeles, with a time of 22.95 seconds.<ref name="upi0582">{{Cite news |last=Hanauer |first=Joan |date=26 May 1982 |title=Cube Contest |work=United Press International |url=http://www.upi.com/Archives/1982/05/26/CUBE-CONTEST/9176391233600/}}</ref>

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.<ref>{{Cite web |title=World Cube Association Official Results |url=http://www.worldcubeassociation.org/results/regions.php?regionId=&eventId=333&years=&history=History |access-date=16 February 2008 |publisher=World Cube Association |archive-date=7 June 2019 |archive-url=https://web.archive.org/web/20190607053724/https://www.worldcubeassociation.org/results/regions.php?regionId=&eventId=333&years=&history=History |url-status=dead }}</ref>
In 2004, the WCA made it mandatory to use a special timing device called a Stackmat timer.

In addition to the main 3x3x3 event, the WCA also holds events where the cube is solved in different ways:<ref>{{Cite web |date=9 April 2008 |title=Competition Regulations, Article 9: Events |url=http://www.worldcubeassociation.org/regulations/#events |access-date=16 April 2008 |publisher=World Cube Association}}</ref>
* Blindfolded solving<ref>{{Cite web |title=Rubik's 3x3x3 Cube: Blindfolded records |url=http://www.worldcubeassociation.org/results/events.php?eventId=333bf&regionId=&years=&show=100%2BPersons&single=Single |access-date=20 June 2012 |website=WorldCubeAssociation.org |archive-date=10 December 2015 |archive-url=https://web.archive.org/web/20151210223215/https://www.worldcubeassociation.org/results/events.php?eventId=333bf&regionId=&years=&show=100%2BPersons&single=Single |url-status=dead }}</ref>
* Multiple blindfolded solving, or "multi-blind", in which the contestant solves any number of cubes blindfolded in a row<ref>{{Cite web |title=WCA Regulations – World Cube Association |url=https://www.worldcubeassociation.org/regulations/#9b3 |access-date=5 April 2018 |website=worldcubeassociation.org}}</ref>
* Solving the cube using a single hand, or one handed solving<ref>{{Cite web |title=Rubik's 3x3x3 Cube: One-handed |url=http://www.worldcubeassociation.org/results/events.php?eventId=333oh&regionId=&years=&show=100%2BPersons&single=Single |access-date=20 June 2012 |publisher=Worldcubeassociation.org |archive-date=10 December 2015 |archive-url=https://web.archive.org/web/20151210204142/https://www.worldcubeassociation.org/results/events.php?eventId=333oh&regionId=&years=&show=100%2BPersons&single=Single |url-status=dead }}</ref>
* Solving the cube in the fewest possible moves<ref name="fmc">{{Cite web |title=Rankings &#124; World Cube Association |url=https://worldcubeassociation.org/results/rankings/333fm/single |website=worldcubeassociation.org}}</ref>

In blindfolded solving, the contestant first studies the scrambled cube (i.e., looking at it normally with no blindfold), and is then blindfolded before beginning to turn the cube's faces. Their recorded time for this event includes both the time spent memorizing the cube and the time spent manipulating it.

In multiple blindfolded solving, all of the cubes are memorised, and then all of the cubes are solved once blindfolded; thus, the main challenge is memorising many&nbsp;– often ten or more&nbsp;– separate cubes. The event is scored not by time but by the number of points achieved after the one-hour time limit has elapsed. The number of points achieved is equal to the number of cubes solved correctly, minus the number of cubes unsolved after the end of the attempt, where a greater number of points is better. If multiple competitors achieve the same number of points, rankings are assessed based on the total time of the attempt, with a shorter time being better.

In fewest moves solving, the contestant is given one hour to find a solution and must write it down.
