Ultimate is a seven-a-side team sport played with a flying disc. It is played on a rectangular field, about half the width of a football field, with an end zone at each end. The objective of each team is to score a goal by having a player catch a pass in the end zone that they are attacking. A thrower may not run with the disc, but may pass the disc in any direction to any team-mate. Any time a pass is incomplete, a turnover occurs, and the other team shall take possession and attempt to score in the opposite end zone. Games are typically played to 15 goals or around 100 minutes. Ultimate is self-officiated and non-contact. The Spirit of the Game guides how players officiate the game and conduct themselves on the field.Many of these rules are general in nature and cover most situations, however some rules cover specific situations and override the general case.Variations to the basic structure and rules may be used to accommodate special competitions, number of players, age of players or available space. Refer to the relevant Appendix for additional rules that apply at specific types of World Flying Disc Federation (WFDF) Events.
