According to Mudbloods, a new documentary about how muggles play Quidditch in real life, the rules of the game are adapted from the Harry Potter books and films.
Players who wear white headbands are chasers.
Black headbands are beaters.
And green headbands signify keepers.
One way to score points in Quidditch is for the chaser to put the Quaffle through one of the three hoops on the field.
Players are allowed to score using any of the hoops from either side.
This earns your team 10 points each time the Quaffle is put through a hoop.
Since Quidditch is a full contact sport, "players can do one-handed tackles, but anything from behind or over the shoulder is not allowed."
Sounds easy enough.
Here's a clip you can watch from the Mudbloods film:
