Spirit of the Game sets Ultimate apart from other competitive team sports. For over 30 years, Ultimate has flourished, reaching a highly competitive level, without the use of referees. In Ultimate, the honor system works. Sure, human nature rears its ugly head from time to time - just as in any sport, just as in life.

 

Yet, one of the many beauties of Ultimate is how, even amid the most difficult of situations, utmost graciousness is allowed to meet that challenge head on. Through this balance, Ultimate players are free to demonstrate the most honorable and the most joyous sides of human nature in sport.
