The competition is a knock-out tournament. In each round of games the teams are paired at random, with the first team drawn listed as the home team. Every game lasts 90 minutes plus any additional stoppage time. The winner of each game advances to the next round, whilst the loser is eliminated from the tournament. If a game ends in a draw, the fixture is replayed at the home ground of the other team at a later date. If the replay also ends in a draw, 30 minutes of extra time is played followed by a penalty shoot-out if there is still no clear winner. In the semi-final and final rounds, if the game ends in a draw there is no replay; the winner is decided either in extra time or by a penalty shoot-out.
