The objective is for a team to outscore the other team by making the most 'tries' or 'touch downs' over the end line.
4 downs
Teams get four downs to move the ball 10 yards. If they gain the 10 yards, they get a new set of four downs. This can continue indefinitely until either the team scores, time runs out in the half or the game, or the team gives up or loses possession of the ball. In Canadian football, teams get three downs to move the ball 10 yards.
