American football, known as football in the United States, is a team sport played between two teams of 11 players with an oval ball on a rectangular field 120 yards (109.73 Meters) long and 53.3 yards (48.74 Meters) wide with goalposts at either end.
The team in possession of the ball (the offense) attempts to advance down the field by running with or passing the ball. In order to continue their drive, the offense must advance the ball at least 10 yards down the field in a series of four downs.
If they succeed, they receive a new set of four downs to continue their drive, but if they fail, they lose control of the ball to the opposing team. The offense can score points by advancing the ball into the end zone (a touchdown) or by place or drop kicking the ball through the opponent's goalpost (a field goal), while the defence can score points by forcing an offensive turnover and advancing the ball into the offense's end zone or by tackling the ballcarrier in the offense's end zone (a safety). The team that has scored the most points by the end of the game wins.
