response: I have no clue how long the games go on for but the winner is the team who got the most points.
original_response: It lasts for 90minutes, the team with the most point wins at the end
history: American football is so popular but i dont care for it much. Do you know about American football? It is referred to as football in the United States and Canada. Yea since other countries use football for what we call soccer. Yeah, another feature of it is that there are two 11 player teams playing on a rectangular field, there are goalposts at both ends. 11 players? thats more than I thought, how long do games last?
knowledge: The team with the most points at the end of a game wins.
