Quidditch, the high-flying sport played on broomsticks, isn't just for wizards anymore. Muggle quidditch, or ground quidditch, is played by intramural leagues worldwide, and more than 65 colleges in 25 U.S. states participate in the annual Quidditch World Cup.
How is a sport that involves flying broomsticks and magical balls played on the ground? Like the wizarding version, players straddle broomsticks, and Chasers toss the "quaffle" — in this case, a volleyball — through hoops. Beaters throw "bludgers," or dodgeballs, at the Chasers to cause them to drop the quaffle. The golden snitch is typically a fast runner dressed in yellow who has a tennis ball in a sock dangling from his or her back pocket. The Seekers chase the snitch outside the playing field — often over an entire college campus — until they grab the tennis ball, ending the game and scoring an extra 150 points.
