During a football game, teams must advance the ball ten yards in four plays. The team that achieves this goal will receive a fourth down and may then attempt to move the ball further or punt it. If the team is unsuccessful, the opponents take possession and the game continues. Points are scored when the team advances the ball to the end zone, or kicks the ball through the goal posts. The team that scores the most points wins.
The national teams of every continent play in championships. Each team wins a certain number of games to advance to the next level. The top team in each division is declared the champion of that division, and may be promoted to the next division if they are successful. The bottom team in the league may be relegated to a lower division, while the team that finishes as the second or third seed will move on to the next stage of the competition.
The game is played with two teams of eleven to eighteen players, with some variation of the game having fewer players per team. The playing field is clearly defined, and the goal is to get the ball to the opposing team’s goal area, over a line, and between the goalposts. The goal is scored when the ball is fully in the opposing team’s net. A player is allowed three substitutions, and they must wear the appropriate footwear.
