Football is a sport played between two teams of 11 players each on a rectangular field with goalposts at each end. The objective is to score points by advancing the football into the opposing team's end zone. Points are scored by carrying the ball across the goal line for a touchdown or kicking it through the goalposts for a field goal. The team with the most points at the end of the game wins. Players advance the ball down the field by running with it or passing it to teammates. The defense tries to stop the offensive team and take control of the ball through tackles, blocking passes.
