"Gaelic Football is a field game which has developed as a distinct game similar to the progression of Australian Rules. Gaelic Football is played on a pitch up to 145m long and 90m wide. The goalposts are the same shape as on a rugby pitch, with the crossbar lower than a rugby one and slightly higher than a soccer one.
The ball used in Gaelic Football is round, slightly smaller than a soccer ball. It can be carried in the hand for a distance of four steps and can be kicked or "hand-passed", a striking motion with the hand or fist. After every four steps the ball must be either bounced or "solo-ed", an action of dropping the ball onto the foot and kicking it back into the hand. You may not bounce the ball twice in a row"
