Association football is a sport played between two teams. In the United States, Canada and Australia, it is called soccer. In most other English-speaking countries it is called football. Association football is the most popular sport in the world.

Games like football have been played around the world since ancient times. The modern game came from England, where the Football Association wrote a standard set of rules for the game in 1863.

Each team has 11 players on the field. One of these players is the goalkeeper, the only player who is allowed to touch the ball with their hands. The other ten are known as "outfield players". The players try to kick the ball into their opponents' goal. The team that scores the most goals wins. A match has 90 minutes of play, with a break of 15 minutes during the match. The break in the middle is called half-time. Added time may be added after half time or after 90 minutes to make up for time lost during the game because of fouls, free kicks, corner kicks, injuries, bookings, substitutions or any other time the game is stopped. A match can end in a tie, except in some competition games where one team must win. In that case, extra-time with two halves of 15 minutes each may be played, and if there is still a tie, a penalty shootout decides the winner. Sometimes extra-time is skipped and the game goes right into the penalty shootout.
