How It's Played
Two teams of seven compete on a grass or artificial turf field 100m × 37m, with an end zone at each end. The disc moves downfield through passing — the player holding the disc cannot run. A point is scored when a player catches the disc in the opposing end zone. Possession changes when a pass is incomplete, intercepted, or goes out of bounds. Games are played to a set number of points across two halves. Mixed Ultimate — four men and three women, or four women and three men per side — is the format played at The World Games, reflecting the sport's longstanding commitment to gender equity.

Spirit of the Game
What sets Ultimate apart is that there are no referees — at any level, including World Championships. Players are solely responsible for calling and resolving their own fouls and violations. This principle, known as Spirit of the Game, is embedded in the rules and the culture of the sport. Competitive play is encouraged, but never at the expense of respect, integrity, and the basic joy of play.

The Sport's History
Ultimate was invented in 1968 by a group of students in Maplewood, New Jersey. From those first games on a school car park, it has grown into a global sport with active player communities on every continent. The first World Championships were held in 1983 in Gothenburg, Sweden. WFDF gained full recognition from the International Olympic Committee in 2015, and Ultimate has featured at The World Games since 2001. Active player numbers have grown at over 12% year on year, making Ultimate one of the fastest-growing team sports in the world.

Compete
WFDF sanctions World Championship events across multiple divisions — Open, Women's, Mixed, Under-24, Junior, and Masters — as well as continental championships on every continent. National member federations in over 100 countries organise their own domestic leagues and national championships.
