There is no offside rule, and consequently the ability to hit the sliotar great distances is essential. If the ball passes over either end line, having hit a defending player last, a 65m free is awarded to the attacking team. 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. A '65' is signalled by the raising of the outside arm.
Players wear a jersey with their team colours, and number on the back.
Both teams must have differing jerseys. Goalkeepers jerseys may not be similar to the jersey of any other player. Referees normally tog out in black jerseys. 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.
