Quidditch

It is possible that you're looking not for Quidditch but for Australian Indoor-Rules Quiddich, a game played in PPC HQ by agents.

A game native to Harry Potter, played on broomsticks, and with four balls: the bright red Quaffle, the two black Bludgers and the tiny, golden, winged Golden Snitch.

There are seven players on a Quidditch team: three Chasers, two Beaters, one Seeker and one Keeper. The aim of the game is to score as many points as possible. Ten points are scored each time the Quaffle passes through a hoop (each end of the pitch has three hoops, which are guarded by the Keeper), and only the Chasers and the Keeper may handle the Quaffle.

The Bludgers, meanwhile, fly around attempting to knock people off their brooms, and each team is guarded by two Beaters, who are equipped with bats to knock the Bludgers away from their team-members.

Whilst all of this is happening, the Seeker flies around looking for the Golden Snitch. Catching the Snitch means 150 points for the Seeker's team, and the end of the game. No game may end until the Snitch is caught, which has occasionally made for some very long games (the record being three months).
