The objective of this game is to score more points than the opponent during the allotted time. Points are scored as long as one of the teams controls the ball. 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).
