Field hockey (or simply hockey) is a team sport structured in standard hockey format, in which each team plays with 11 players in total, made up of 10 field players and a goalkeeper. Teams must move a hockey ball around a field by hitting it with a hockey stick towards the rival team's shooting circle and then into the goal. The match is won by the team that scores the most goals. Matches are played on grass, watered turf, artificial turf, or indoor boarded surface. Street hockey is a form of impromptu field hockey typically played by children in Canada, via erecting a net in the street and using the road surface to play.
