Each play constitutes a <answer>down</answer>. The offence must advance the ball at least ten yards towards the opponents' goal line within three <answer>down</answer>s or forfeit the ball to their opponents. Once ten yards have been gained the offence gains a new set of three <answer>down</answer>s (rather than the four <answer>down</answer>s given in American football). Downs do not accumulate. If the offensive team completes 10 yards on their first play, they lose the other two <answer>down</answer>s and are granted another set of three. If a team fails to gain ten yards in two <answer>down</answer>s they usually punt the ball on third <answer>down</answer> or try to kick a field goal (see below), depending on their position on the field. The team may, however use its third <answer>down</answer> in an attempt to advance the ball and gain a cumulative 10 yards.
