"It's a game that's played on flying broomsticks," Hermione says first, because with the fictional depictions of witches and wizards through the years, the flying broomstick is probably one of the details that lingers best in people's minds. It's far from the only means of transportation, thankfully, but Hermione wouldn't be surprised if one of the reasons why so many Muggles hold to the idea of the flying broomstick is because a game of Quidditch wasn't kept far enough away from curious eyes.

"There are two teams of seven in a game, and three different types of balls that are played with. One of the balls is meant for simple scoring — players on broomsticks work to pass those balls through any one of the opposing team's three hoops, similar to basketball. Another type of ball is meant for interference, and a pair of players try to hit those balls towards the opposing team to interrupt their progress. The last is a ball which ends the game, very small and capable of dodging on its own. Grab that ball, and the team gets many additional points, and the game itself is concluded."
