The World Cube Association (WCA) is the international governing body for competitions that include mechanical puzzles. The most famous of these is the Rubik’s Cube, invented by Professor Rubik from Hungary. Over the last ten years, more than 100,000 participants have taken part in competitions overseen by the WCA. Despite its popularity, WCA is entirely run by volunteers. It is an enormous task as currently there are over 100,000 competitions from over 140 countries. Despite the scale of the international participation, there are only plans for further expansion.
The flagship competition is the World Championship run every two years. This requires meticulous planning in terms of volunteers and financial backing. Competitions are for both men and women with current world records in 17 separate categories. WCA is based in the United States.
