Spirit of the Game is the most important rule in flying disc sports. It is similar to Fair Play in other sports but there is a much higher emphasis put on it in (Beach) Ultimate. It is summarised in this preamble to the rules of play:
“All players are responsible for administering and adhering to the rules. Ultimate relies upon a Spirit of the Game that places the responsibility for fair play on every player. It is trusted that no player will intentionally break the rules; thus there are no harsh penalties for breaches, but rather a method for resuming play in a manner which simulates what would most likely have occurred had there been no breach. Highly competitive play is encouraged, but should never sacrifice the mutual respect between players, adherence to the agreed-upon rules of the game, or the basic joy of play.”
