In a two-point conversion attempt, the side that just scored must run a play from near the opponent's goal line (5-yard line in Canada, 3-yard line in amateur America, 2-yard line in professional America) and advance the ball across the goal line as if scoring a touchdown. If successful, they have converted their two-point try. The ball is placed at the 5-yard line on the back end of a standard football formation. Two players from each team will be positioned behind their respective sides' lines with room to run if they get the ball. The remaining player from each team will be in the center of the field ready to snap the ball if necessary. In order for the conversion to be made, all five players involved in the play must reach the end zone. If any player stops short of the goal line when attempting to score, then the try fails and game continues as normal. The two-point conversion was invented by John Henry Johnson who was the coach of Harvard University. He felt that his team lost many games due to a lack of time to score enough points to win. So he created this new rule so that his team would have a chance to win even if they were behind by more than 10 points in the last minute of play.
