wca

WCA commonly refers to the World Cube Association, the international governing body for official speedcubing competitions. It coordinates the rules, judging standards, competition formats, and results for official puzzles and maintains world records and rankings. The organization certifies competition organizers and judges, and assigns each competitor a WCA ID to track results across events. Local, national, and regional competitions are held worldwide, culminating in major championships such as the World Championship and continental championships.

Official events cover a range of puzzles, most notably the 3×3×3 cube, but also 2×2×2, 4×4×4, 5×5×5, 6×6×6, and 7×7×7 cubes, as well as Megaminx, Pyraminx, Skewb, and Clock. The organization also governs special formats such as the Fewest Moves (FMC) and blindfolded variants, including 3×3 Blindfolded and multi-blind. One-handed solving is another widely recognized category. Rounds and formats are defined by WCA rules; scrambles are generated by standard algorithms to ensure fairness, and times are measured with official timing devices.

Results are published in the public WCA database, providing global rankings and world records for each official event. The WCA is operated by volunteers and a board of directors, supported by a network of regional and national organizers who manage events, judges, and scorekeeping. Through its governance and data infrastructure, the WCA standardizes competitive speedcubing and fosters an international community of competitors, coaches, and enthusiasts.
