Ultimate, originally known as ultimate frisbee, is a non-contact team sport originally played by players with a flying disc (frisbee). The term Frisbee, often used to generically describe all flying discs, is a registered trademark of the Wham-O toy company, and thus the sport is not referred to as Ultimate Frisbee. Points are scored by passing the disc to a teammate in the opposing end zone.Other basic rules are that players must not take steps while holding the disc, and interceptions, incomplete passes, and passes out of bounds are turnovers. Rain, wind, or occasionally other adversities can make for a testing match with rapid turnovers, heightening the pressure of play.
