American football is played on a 100 yard field with end zones at each end where touchdowns are scored. The game consists of four 15 minute quarters with a halftime break between the second and third quarters. Teams score points through touchdowns worth 6 points, extra points worth 1 point, or field goals worth 3 points. Each team has 4 downs to advance the ball 10 yards before losing possession. Players line up based on the line of scrimmage and aim to move the ball down the field through passing and running plays utilizing different positions like quarterback, receivers, running backs, and linemen on both offense and defense.
