Quidditch

Quidditch is played in the air. Three chasers move a ball through hoops. Two beaters swat heavy balls at opponents. A keeper guards the hoops. A seeker chases the snitch, a small golden ball whose catch is worth a large score and usually ends the game.

The rules are knowingly lopsided. A seeker can erase an hour of ordinary scoring, which is excellent drama and questionable sport design. House teams turn the school into a stadium with rival colors.

This is a rules sketch in original words, not a reprint of a rulebook. Films later invented the camera language; the page invented the unfairness.
