Picigin's foundations are right here in Split, and it is considered the Split's sport. It's held in June. The so called "World Championship in Picigin" has been a tradition ever since 2005. Until 2008 the Championship was graded according to given forms of the player's jumps, but since 2008 the overall artistic impression is also part of the grade. The Picigin game rules are determined by the members of the Eco-association "Picigin Bačvice".
