A play from scrimmage is the activity of the games of Canadian football and American football during which one team tries to advance the ball, get a first down, or to score, and the other team tries to stop them or take the ball away.
Once a play is over, and before the next play starts, the football is considered dead.
A game of American football ( or Canadian Football ) consists of many ( about 120-150 ) such plays.
