Minus the capes but straddling a broomstick the students of Tufts University and Boston University played Harry Potter's favourite sports of Quidditch. The games sticks to most of JK Rowling's rules including having chasers and the quaffle, or ball. The result is a cross between dodge-ball and handball, with a bit of lacrosse thrown in.
Muggle Quidditch teams have seven players: three chasers, two beaters, a keeper, and a seeker. Chasers score points by throwing a quaffle through one of three hoops, which is worth 10 points, while trying to avoid bludgers, or dodgeballs, that are thrown by beaters.
The keeper’s job is to protect the three goalposts, while the seeker must capture the snitch.
