Speedcubing (also known as speedsolving, or cubing) is a competitive sport involving solving a variety of combination puzzles, the most famous being the 3x3x3 puzzle or Rubik's Cube, as quickly as possible. A person who practices solving twisty puzzles is known as a speedcuber (when solved specifically focusing on speed), or a cuber. For most puzzles, solving involves performing a series of moves or sequences that alters a scrambled puzzle into a solved state, in which every face of the puzzle is a single, solid color. Competitive speedcubing is mainly regulated by the World Cube Association (WCA). The WCA currently recognizes 17 speedcubing events: the cubic puzzles from the 2x2–7x7, the Pyraminx, Megaminx, Skewb, Square-1, and Rubik's Clock, as well as the 3x3, 4x4, and 5x5 Blindfolded, 3x3 One-handed, 3x3 Fewest Moves, and 3x3 Multi-blind. , the 3x3x3 world record single in competition is 3.47 seconds by Yusheng Du. The 3x3x3 world record for a trimmed average of five solves is 4.86 seconds, tied by Max Park and Tymon Kolasiński. History The Rubik's Cube was invented in 1974 by Hungarian professor of architecture Ernő Rubik (Born 13 July 1944).

On June 5, 1982, the first world championship was held in Budapest, Hungary. Nineteen people competed in the event and the American Minh Thai won with a single solve time of 22.95 seconds, which was, at the time, the fastest Rubik's Cube solve ever recorded in competition. Other notable attendees include Jessica Fridrich and Lars Petrus, both people who later became influential in the development of solving methods and the speedcubing community. The Rubik's Cube waned in popularity after 1983, but with the advent of the Internet, sites began to surface to discuss the cube. With these websites facilitating the renewed popularity of the cube, it ushered in a new generation of cubers, creating a growing international community of people dedicated to the sport of speedsolving. Those prominent in the online community such as Ron van Bruchem, Tyson Mao, Chris Hardwick, and Ton Dennenbroek eventually wanted to create a place where cubers from around the world can meet and compete. In 2003 they organized a second championship in Toronto, Ontario followed by another competition in the Netherlands later that same year. This revival of competition sparked a
