Football is the world's most popular sport, with an estimated 250 million players active in over 200 countries and territories. It is played by two teams of eleven players on a rectangular field, with a goal at each end. The objective of the game is to score goals by kicking or heading the ball into the opposing team's goal.

The game is played in a variety of formats, from the professional leagues of Europe and South America to the amateur leagues of Africa and Asia. The rules of the game are similar in all countries, although there are some variations in the size of the field, the number of players, and the duration of the game.

In most countries, the game is played between two teams of eleven players. Each team has a goalkeeper, four defenders, three midfielders, and three forwards. The goalkeeper is the only player who is allowed to touch the ball with his hands. The other players use their feet, heads, and chests to pass, dribble, and shoot the ball.

The attacking team, usually the team with the ball, attempts to score a goal by kicking the ball beyond the opposing team's goalkeeper, between the goalposts, and beneath the crossbar. The defending team attempts to prevent the attacking team from scoring by blocking shots, intercepting passes, and tackling players.

The game is divided into two halves, each lasting 45 minutes. At the end of each half, the teams switch sides and the referee blows the whistle to signal the end of the half. If the score is tied at the end of the game, the teams may play extra time or a penalty shootout to determine the winner.

The most popular form of football is association football, or soccer, which is played in most countries around the world. Other popular forms of football include American football, Australian rules football, rugby union, and rugby league.
