Rule of Ultimate 1.4:
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.
Spirit of the Game is what sets Ultimate apart from all other sports. The ownership of the game is with each and every player. The game is entrusted to everyone – not just the noble. It cannot be played without fairness.
This means know the rules, avoid body contact, speak respectfully in a disagreement, be fair in every situation and have as much fun as you can while doing it.
