Some call it Ultimate Frisbee, others may call it Frisbee Football or Ultimate Disc ‐‐ but the official name of the sport is just "Ultimate." The game is played on a field roughly the size of a football field. There are seven players on each team. A team scores by advancing the Disc (Frisbee) to the opponent's end‐zone. A player cannot run with the disc ‐‐ thus the only method of advancing the disc is by throwing the disc to a team‐mate. A turnover results from an incomplete pass, a catch out‐of‐bounds, or from the other team intercepting the disc. After a turnover the other team immediately picks up the disc and tries to advance the disc to their opponents end‐zone. Generally the teams play to a predetermined score (ie, 15 points). A score is worth one point.
