The following rules are the 10 basic rules in Ultimate Frisbee.  For a complete set of detailed rules, click here for the UPA (Ultimate Players Association) website.

1. Captain’s Set up the Field
   A rectangular shape with endzones at each end. An NSP field is 60 yards by 30 yards, with endzones 15 yards deep.

2. To Initiate Play
   NSP games are played with (5) five players per team (a minimum of (2) people per gender plus an extra of either gender).   The opposing team can waive the default of minimum players at their discretion provided it is prior to the start of the game.

   Each point begins with both teams lining up on the front of their respective endzone line. The defense throws ("pulls") the disc to the offense. The receiving team has the option of catching the disc or letting it fall, but if they attempt to catch it & drop it, it is an automatic turnover. THE PULL CANNOT BE KNOCKED DOWN BY THE DEFENSE. Players must play the disc from where it lands, unless it lands in the endzone then you walk it up to the endzone line. The receiving team does not have to wait to have the disc "tagged in" off the pull. Whoever retrieves the disc off of a pull or from any throw that lands out of bounds must play it. It cannot be handed over to someone else to commence play.

   If the pull goes directly out of bounds, the receiving team may call "centre" and play the disc from the middle of the field at the point where the disc crossed the boundary. If the disc rolls out, "centre" may not be called.

3. Movement of the Disc
   The disc may be advanced in any direction by completing a pass to a teammate. Players may not run with the disc. The person with the disc ("thrower") has ten seconds to throw the disc. The defender guarding the thrower ("marker") counts out the stall count.   The marker can be no closer than one arm-length from the thrower. Zone defense is not permitted.

4. Scoring
   Each time the offense completes a pass in the defense's endzone, the offense scores a point. Play is initiated after each score.   Games are won by the first team to reach 17 points or the team ahead after 1 hour and 20 minutes (a five minute half-time is taken after one team reaches 9 points or 40 minutes has passed).  In NSP leagues, teams must gain half before scoring.  If a disc is thrown from before center is reached and results in a catch in the end zone, the result is a turnover, with the defending team taking possession at their own goal line.

5. Change of possession
   When a pass in not completed (e.g. out of bounds, drop, block, interception), the defense immediately takes possession of the disc and becomes the offense.

6. Substitutions
   Players not in the game may replace players in the game ONLY after a score or during an injury timeout.

7. Non-contact
   No physical contact is allowed between players. Picks and screens are also prohibited. A foul occurs when contact is made.

8. Fouls
   When a player initiates contact on another player a foul occurs. When a foul disrupts possession, the play resumes as if the possession was retained. If the player committing the foul disagrees with the foul call, the play is redone.

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

10. Spirit of the Game
    Ultimate stresses sportsmanship and fair play. Competitive play is encouraged, but never at the expense of respect between players, adherence to the rules, and the basic joy of play.
