[1] The objective of this game is to score more points than the opponent
during the allotted time. The team with the ball (the offense) has 4 tries (
downs) to advance at least 10 yards, and can score points once they reach or
near the opposite end of the field, called the end zone. If the offense
does not advance at least 10 yards during their 4 downs, the team without
the ball (the defense) regains control of the ball (called turnover on downs
).
On offense, points are scored by advancing the ball into the opponent's end
zone for a touchdown (worth six points), or by kicking the ball from the
playing field through the raised vertical posts (the goal posts) in the back
of that end zone for a field goal (worth three points). After scoring a
touchdown, the offense is given one additional play from the 2 yard line (3
yard line in amateur football) to attempt to score. These attempts are
termed point after touchdown (PAT) and are used to score 1 or 2 points as
follows:
The offense may attempt a field goal kick which is worth 1 point.
The offense may attempt to readvance the ball into the opponent's end
zone for a two-point conversion worth 2 points.
While the opposing team has possession, the defense attempts to prevent the
offense from advancing the ball and scoring. If an offensive player loses
the ball during play (a fumble) or the ball is caught by a defensive player
while still in the air (an interception), the defense may attempt to run
into the offense's end zone for a touchdown. The defense may also score
points by tackling the ball carrier in the offense's own end zone, called a
safety (which is worth two points). |
