Although Ultimate resembles many traditional sports in its athletic requirements, it is unlike most sports due to its focus on self-officiating, even at the highest levels of competition. This concept, called Spirit of the Game, is integrated into the basic philosophy of the sport, written into the rules, and practiced at all levels of the game from local leagues to the World Games. 

Combining the non-stop movement and athletic endurance of soccer with the aerial passing skills of football, a game of Ultimate is played by two teams with a flying disc or Frisbee™ on a field with end zones, similar to football. The object of the game is to score by catching a pass in the opponent’s end zone. A player must stop running while in possession of the disc, but may pivot and pass to any of the other receivers on the field. 

Ultimate is a transition game in which players move quickly from offense to defense on turnovers that occur with a dropped pass, an interception, a pass out of bounds, or when a player is caught holding the disc for more than ten seconds.
