Football is played between two teams of 11 players on the field of play at any one time. Each team tries to score into the opponent's goal and to prevent the other team from scoring. The ball may be passed, tapped, rolled or dribbled in any direction using the feet, as well as thrown from the sideline in the case of a throw-in. Playing time is made up of two periods of 40 minutes with a half-time break of 15 minutes. At the final whistle, the team which scores more goals is the winner.
