How American Football Works
American football is played between two teams of 11. The offensive team tries to advance the ball down a 100-yard field to score a touchdown (6 points). The defensive team tries to stop them. Teams alternate between offense and defense.
How It Works
- 1The offensive team has 4 "downs" (attempts) to advance the ball 10 yards
- 2If they gain 10 yards, they get a new set of 4 downs
- 3If they fail after 4 downs, possession transfers to the other team
- 4On 4th down, teams often "punt" the ball away to improve field position
- 5The game is divided into four 15-minute quarters with a halftime break
Scoring
Touchdown = 6 points (ball crosses goal line). Extra Point after TD = 1 (kick) or 2 (run/pass). Field Goal = 3 points (ball kicked through goalposts). Safety = 2 points (defensive team tackles offense in own endzone).
