To score more points than the opposing team by the end of the time. Basics:
* There are two 11-person teams that play against each other throughout the game. * The game lasts for 60 minutes, split into four quarters of 15 minutes each. * At the end of the 1st half or the 2nd quarter, there is a break, and the game continues after about 15-20 minutes * The primary objective of one team (the offense) is to take the ball and try to advance it (by either passing the ball or running with the ball) to the opposing team's end zone, while the other team's (the defense) objective is to try and stop the advancing team. If the offense is successful and a player carries the ball into the end zone, they score a touchdown. The two teams take turns between playing the offensive or defensive roles. * The playing area is 100 yards long with 10 extra yards on each. * At the back of each end zone, there is a goal post.
* backfield: the area behind the line of scrimmage.
* blocking: the act of preventing a defensive player from getting to the ball carrier;blockers use their arms and bodies but may not hold an opponent. * Blitz-a play where the defensive team sends players rushing towards the line of scrimmage as soon as the ball is snapped to try to sack the quarterback. * dead ball: a ball becomes dead when a play is over and becomes live as soon as it is snapped for the next play. * fumble: when a ball carrier loses possession by dropping the ball or having it knocked away before a play ends; the first player to regain possession of the loose ball is said to make the recovery, and his team becomes the offense. *
interception: a pass caught in the air by a defender whose team immediately gains possession of the ball and becomes the offense.
