Australian Indoor-Rules Quiddich came from the webcomic Mac Hall and is the focus of the All-HQ Australian Indoor-Rules Quiddich League. The rules are as follows: "Australian Indoor-Rules Quiddich is played with a dark hallway and a hard rubber ball. The best kind is a rubber ball with a solid core and an LED in the center that lights up on impact. Sometimes they give them away at trade shows or conventions as a promotional freebie. The hallway should be as close to pitch-black as you can get it. No score is kept and there is no clear way to win. Play continues until you stop. "
