The World Cube Association (WCA) is the worldwide non-profit organization that regulates and holds competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as twisty puzzles (a subcategory of combination puzzles). The most famous of those puzzles is the Rubik's Cube. The WCA was founded by Ron van Bruchem of the Netherlands and Tyson Mao of the United States in 2004. The goal of the World Cube Association is to have "more competitions in more countries with more people and more fun, under fair conditions." In 2017, they started work to become a non-profit organization and on November 20, 2017, the state of California accepted the initial registration of the World Cube Association. The organization is run by the board members. It assigns different teams and committees as well as delegates who can organize official competitions. The presence of a delegate is required to make the competition official. As of June 2022, more than 160,000 people from around the world have participated in WCA competitions and over 7,500 competitions have been held. (Wikipedia).
