Last fun part i forgot to mention in the game - The Change of possession

The most fun part in the game...

• The team fails to get a first down, in four downs they fail to move the ball past a line 10 yards ahead of where they got their last first down. The defensive team takes over the ball at the spot where the 4th-down play ends. A change of possession in this manner is commonly called turnover.
• The offense scores a touchdown or field goal. The team that scored then kicks the ball to the other team in a special play called kickoff.
  
• The offense punts the ball to the defense. A Punt is a kick in which a player drops the ball and kicks it before it hits the ground. Punts are nearly always made on fourth down, when the offensive team does not want to risk giving up the ball to the other team at its current spot on the field (through a failed attempt to make a first down) and feels it is too far from the other team's goal post to attempt a field goal.
• A defensive player catches a forward pass. This is called an interception and the player who makes the interception can run with the ball until he is tackled, forced out of bounds, or scores.
• An offensive player drops the ball fumbles and a defensive player picks it up. As with interceptions, a player recovering a fumble can run with the ball until tackled, forced out of bounds, or scoring. Passes that are thrown either backwards or parallel with the line of scrimmage (lateral passes) that are not caught do not cause the down to end as incomplete forward passes do; instead the ball is still live as if it had been fumbled. Lost fumbles and interceptions are together known as turnovers.
• While in his own end zone, an offensive ball carrier is tackled, forced out of bounds, loses the ball out of bounds, or the offense commits certain fouls in the end zone. This fairly rare occurrence is called Safety play.
