Gaelic football resembles a combination of basketball and soccer, and is similar in appearance to Australian rules football with the exception that the ball is the shape of a soccer ball but is slightly smaller and harder. It is played on a rectangular field (larger than a soccer field) by two teams of thirteen. There are men's and women's teams and the rules are very similar.
Unlike certain other sports, the rules are intentionally designed to keep the game moving quickly and to keep any stoppages short without sacrificing any skill element. Therefore there is no offside rule except for the fact that an attacking player must not be in the goalkeeper's area before the ball.
