Gaelic football (Irish: Peil Ghaelach; short name Peil), commonly known as simply Gaelic, GAA, or football, is an Irish team sport. A form of football, it is played between two teams of 15 players on a rectangular grass pitch. The objective of the sport is to score by kicking or palming the ball into the other team's goal (3 points) or between two upright posts above the goal and over a crossbar 2.5 metres (8 ft 2 in) above the ground (1 point).
Players advance the ball up the field with a combination of carrying, bouncing, kicking, hand-passing, and soloing (dropping the ball and then toe-kicking the ball upward into the hands). In the game, two types of scores are possible: points and goals. A point is awarded for kicking or hand-passing the ball over the crossbar, signalled by the umpire raising a white flag. Two points are awarded if the ball is kicked over the crossbar from a 40 metre range marked by a D-shaped arc, signalled by the umpire raising an orange flag. A goal is awarded for kicking the ball under the crossbar into the net (the ball cannot be hand-passed into the goal), signalled by the umpire raising a green flag. Positions in Gaelic football are similar to those in other football codes and comprise one goalkeeper, six backs, two midfielders, and six forwards, with a variable number of substitutes.
