Gaelic football is an Irish team sport. It is a form of football derived from traditional Irish ball games. It is played between two teams of 15 players on a rectangular grass pitch. The objective of the sport is to score by passing the ball through the other team's goals (3 points) or a set of two upright posts separated by a crossbar 2.5 metres (8.2 ft) above the ground (1 point).
Players advance the football, a spherical leather 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. A goal is awarded for kicking the ball under the crossbar into the net, signalled by the umpire raising a green flag. Positions in Gaelic football are similar to that in other football codes, and comprise one goalkeeper, six backs, two midfielders, and six forwards, with a variable number of substitutes.
