Ultimate is a flying disc team sport played on a grass or turf field with end zones. Teams advance the disc with aerodynamic throws, with one point scored for each catch in the end zone. Athletes must possess an incredible combination of endurance, speed, agility, technique, and teamwork combined with a strong commitment to fair play in top competition without referees. This timely variation on sport reflects the importance of self-restraint. The athletes must arbitrate their own calls in the heat of competition using a refined system of rules. Invented in 1968, organized competition now takes place on six continents.

Yet the simplicity of the rules means it’s easy and fun for newcomers to pick up.
