Muggle Quidditch is a sport based on Quidditch, the fictional sport developed by British author J. K. Rowling in the Harry Potter series of children's novels.
In Muggle Quidditch, as in fictional Quidditch, there are seven players on each team, 3 chasers, 2 beaters, 1 keeper and 1 seeker. Muggle Quidditch has been adapted for play on the ground, with game play confined to a playing field comparable in size to a hockey rink.
Three circular goals are placed on either side of the pitch. The goals are often hula hoops held up by PVC pipes. All players are required to carry a broom between their legs at all times. Volleyballs are used as the quaffle, and dodgeballs serve as the bludgers. While the Snitch is a magical object within the canon of the Harry Potter novels, in Muggle Quidditch the Snitch is simply a tennis ball contained in a sock tucked in the waistband of the snitch runner. The snitch runner is a neutral player affiliated with neither team dressed in all gold or yellow. After release, the snitch runner (and thereby the snitch itself) is allowed to roam an area beyond the playing field. When played on a college campus the range is often the entire campus. The seekers search for the runner around campus; if they fail to catch him, he returns to the field after a specified time.
The game begins with the quaffle and bludgers placed in the center of the field and all players in line with their respective goalposts. After the snitch is out of sight, the referee yells 'brooms up!' to start the game.

The game is played with six standing hoops, three on each side of the oval shaped pitch. The hoops have differing heights which are 1 metre, 1.4 metres, and 2 metres. The game has 3 different balls in play, the quaffle, the three bludgers, and the snitch.
The Quaffle The quaffle is a volleyball that is able to be held by chasers and keepers. The quaffle is the ball that is used for scoring in the game. It can only be held by chasers or keepers and may pass through either side of the hoop in order for a score to count.
The Bludger The Bludger is typically a slightly under-inflated dodgeball that can only be used by the beaters on the field. There are always 3 bludgers in play at one time so that one team may not have sole control of the bludgers. The bludgers are used to hit any other player on the field. Upon being hit by a bludger thrown by an opposing beater you must dismount your broom and run back to your team's hoops in order to simulate the "knock out effect".
The Snitch The snitch is typically a gold sock with a tennis ball or racquet ball placed inside of it. It must then be tucked into the back of a snitch runner's shorts, like a tail. The snitch runner may do everything in his or her power to protect the snitch sock from being grabbed by seekers. Only seekers may make advances towards the snitch sock or the snitch runner and must attempt to get the snitch sock without making forceful contact with the snitch runner. The game ends when the snitch sock is grabbed by a seeker.

Chasers are responsible for passing the Quaffle and scoring points by throwing the Quaffle through one of the opponent's goals. Three chasers from a team may be in play at one time. When a Bludger hits a Chaser in possession of the Quaffle, he or she must drop the Quaffle and run back to his or her own goalpost to simulate recovery time.
Keepers are the goal protectors (similar to goalkeepers in soccer) and must try to block attempts to score by the opposing team's Chasers. One keeper from a team may be in play at a time. The keeper is invulnerable to Bludgers when within their team's keeper zone, an area around the team's hoops. Once outside of the Keeper zone, the Keeper serves as a 4th Chaser.
Beaters attempt to hit the opposing team's players with Bludgers and attempt to block the Bludgers from hitting their team's players. Two Beaters on a team may be in play at a time.
Seekers attempt to catch the snitch. Though the snitch leaves the pitch at the start of the game and often does not return until a predetermined period has passed, seekers are able to search for the snitch off the pitch throughout the game.
