Spirit of the game
Ultimate relies upon a Spirit of the Game that places the responsibility for fair play on every player. There are no referees; the players are solely responsible for following and enforcing the rules, even at World Championship. Competitive play is encouraged, but never at the expense of respect between players, adherence to the rules, and the basic joy of play.
This sheet provides an outline of the rules only. If you want to participate in official competitions, you should become familiar with the official WFDF rules, which you can find on the WFDF website. In addition, experienced players will gladly teach players the rules and good spirit, so don’t be scared to ask.
