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. You may not bounce the ball twice in a row. Both teams must have different colour jerseys. The goalkeepers' jerseys must not be similar to the jersey of any other player.
Referees normally tog out in black jerseys, socks and togs.
Goalkeepers may not be physically challenged whilst inside their own small parallelogram, but players may harass them into playing a bad pass, or block an attempted pass. Teams are allowed a maximum of three substitutes in a game. Players may switch positions on the field of play as much as they wish but this is usually on the instructions of team officials. A goal is signalled by raising a green flag, placed to the left of the goal. A point is signalled by raising a white flag, placed to the right of goal.
