This is an exceptionally violent and often fatal game that originated in Scotland. A large number of boulders were charmed to hover in the air and each player had a cauldron strapped to his/her head. A horn was sounded, the rocks were released, and the players would fly around on their broomsticks trying to catch as many rocks in their cauldron as possible. The winner was the player who caught the most rocks (this game has been outlawed for many years). This game, as noted in Quidditch Through the Ages, is thought to be the inspiration of the Beater position
