Ultimate Rules & Info
Ultimate is played between two teams of seven players on a large rectangular pitch. A line drawn across the pitch at either end creates two "endzones" (like in Rugby or American Football), which are the goal-scoring areas. A goal is scored when a team completes a pass to a player standing (or more likely running) in the endzone they are attacking.
Players cannot run with the disc. When a player catches the disc they must come to a complete stop and then try to throw it to another player. By passing from player to player, the offence attempts to work the disc up the pitch towards the endzone they are attacking. If the disc hits the ground or is intercepted or knocked down by the other team, then the opposition takes possession of the disc. Possession also changes if a receiver is outside the playing area when he or she catches it.
The defending team attempts to stop the team with the disc from making progress upfield by marking them. The theory is that the offence won't want to pass to a player who is being marked closely, as it's likely to result in an interception. So the offensive players must try to get free of their markers to receive a pass, while the defence makes every effort to stay with them in the hope of forcing a turnover.
Ultimate is essentially non-contact; any contact between players can be declared a foul.
Ultimate is unique in that it is refereed by the players themselves, according to a code of conduct known as "the Spirit of the Game". This places the responsibility for fair play on the players themselves. In that respect, playing Ultimate is a completely different experience to playing other sports. And believe it or not, Ultimate's system of self-refereeing works.
