The Field. A rectangular shape with end zones at each end. A regulation field is 110 yards long by 40 yards wide, with end zones 20 yards deep.

Starting Play. Each point begins with both teams lining up at the front of their end zone. The defense throws (“pulls”) the disc to the offense. A regulation game has seven players per team.

Scoring. A point is scored when the offense catches a pass in the defense’s end zone. 

Movement of the Disc. The disc can be advanced only by throwing it to a teammate—players may not run with the disc. The thrower has ten seconds to throw the disc, which is counted by the defender (the "mark").

Change of Possession. When a pass is not completed (e.g. out of bounds, drop, block, interception, stalled), the disc is turnedover and the other team gets control of the disc.

Substitutions. Players can be replaced between points and during an injury timeout.

Non-Contact. Players must attempt to avoid physical contact during play. Picks and screens are also prohibited.

Fouls. When a player initiates contact that affects the play, a foul occurs. When a foul causes a player to lose possession, the play resumes as if the possession was retained. If the player that the foul was called against disagrees with the foul call, the play is redone.

Self-Officiating. Players are responsible for their own foul and line calls. Players resolve their own disputes.

Spirit of the Game. The foundation of the rules in ultimate is Spirit of the Game, which places the responsibility for fair play on the player. Competitive play is encouraged, but never at the expense of respect between players, adherence to the rules, and the basic joy of play.
