Problem: Information: - American football, referred to as football in the United States and Canada, and also known as gridiron, is a sport played by two teams of eleven players on a rectangular field with goalposts at each end.

The offense must advance at least ten yards in four downs, or plays, or else they turn over the football to the opposing team; if they succeed, they are given a new set of four downs. Points are primarily scored by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal.
