Water polo is a team sport played in a swimming pool, where two teams compete to score goals by throwing a ball into the opposing team's net. Each team consists of seven players: six field players and one goalkeeper. Players swim, pass, and shoot the ball while trying to prevent the other team from scoring. The game is divided into four quarters, and teams score by getting the ball into the goal. Players must tread water and use their swimming skills to maneuver around the pool. Fouls can be called for various infractions, and the game requires both physical endurance and strategic teamwork.
