Quidditch is a fictional sport from the Harry Potter series created by J.K. Rowling. It is played on flying broomsticks and involves four balls: the Quaffle, two Bludgers, and the Golden Snitch. Each team has seven players: three Chasers, two Beaters, one Keeper, and one Seeker. The objective is to score points by throwing the Quaffle through the opponent's hoops while avoiding the Bludgers. A match ends when the Golden Snitch is caught, earning the capturing team an additional 150 points. The game is popular among wizards and witches, with professional teams and a World Cup tournament featured in the series.
