AMERICAN FOOTBALL

American football, known in the United States and Canada simply as football, is a competitive team sport. The object of the game is to score points by advancing the football into the opposing team's end zone. The ball can be advanced by carrying the ball, or by throwing or handing it from one teammate to the other. Points can be scored in a variety of ways, including carrying the ball over the goal line, throwing the ball to another player past the goal line or kicking it through the goal posts on the opposing side. The winner is the team with the most points when the time expires and the last play ends. However, tied games can occur if the score remains tied after the conclusion of an overtime period.

Outside of the United States and Canada, the sport is usually referred to as American football (or sometimes as gridiron or gridiron football) to differentiate it from other football games.
