The Field -- A rectangular shape with endzones
at each end. A regulation field is 70 yards by 40 yards, with endzones
25 yards deep.
Initiate Play -- Each point begins with both
teams lining up on the front of their respective endzone line.
The defense throws ("pulls") the disc to the offense.
A regulation game has seven players per team.
Scoring -- Each time the offense completes
a pass in the defense's endzone, the offense scores a point. Play
is initiated after each score.
Movement of the Disc -- The disc may be advanced
in any direction by completing a pass to a teammate. Players may not
run with the disc. The person with the disc ("thrower")
has ten seconds to throw the disc. The defender guarding the thrower
("marker") counts out the stall count.
Change of possession -- When a pass in not
completed (e.g. out of bounds, drop, block, interception), the defense
immediately takes possession of the disc and becomes the offense.
Substitutions -- Players not in the game may
replace players in the game after a score and during an injury timeout.
Non-contact -- No physical contact is allowed
between players. Picks and screens are also prohibited. A foul occurs
when contact is made.
Fouls -- When a player initiates contact on
another player a foul occurs. When a foul disrupts possession, the
play resumes as if the possession was retained. If the player committing
the foul disagrees with the foul call, the play is redone.
Self-Refereeing -- Players are responsible
for their own foul and line calls. Players resolve their own disputes.
Spirit of the Game -- Ultimate stresses sportsmanship
and fair play. Competitive play is encouraged, but never at the expense
of respect between players, adherence to the rules, and the basic
joy of play.
