Ultimate is unique in that it is played without officials or referees.  This means that Ultimate players are both competitors and officials.  The Spirit of the Game is a set of principles that guides players to mutual respect and trust, communication and conflict resolution, and self-confidence.  Responsibility is placed on each player to know the rules and make their own calls.

Please visit both the USAU and WFDF webpages for Spirit of the Game and read what they say about it.

"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."
