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.
Spirit of the Game is the mindful behaviour practiced by players worldwide prior to, during and after a game. It encompasses attitudes and skills such as good knowledge and application of the rules, fair-mindedness, safe play, and spatial awareness, clear and calm communication, and positive and respectful attitude towards teammates, fans, and opponents, in a mutual effort to protect the basic joy of play.
