The game is thought to have originated in Scotland in the late 19th century as a sort of "water rugby". William Wilson is thought to have developed the game during a similar period. The game thus developed with the formation of the London Water Polo League and has since expanded, becoming widely popular in various places around the world, including Europe, the United States, Brazil, China, Canada and Australia.
Water polo is a team water sport. The game consists of 4 quarters in which the two teams attempt to score goals by throwing the ball into their opponent's goal, with the team with the most goals at the end of the game winning the match.
