Some leagues and competitions may instead use a points percentage system, changing the nature of this statistic. In this type of method, used in many group tournament ranking systems , the competitors are awarded a certain number of points per win, fewer points per tie, and none for a loss. The teams are then ranked by the total number of these accumulated points. One such method is the " three points for a win ", where three points are awarded for winning a game, one point is awarded for a draw, and no points are awarded for a loss. The National Hockey League (which uses an overtime and shootouts to break all ties) awards two points for a win in regulation or overtime/shootout, one point for an overtime loss, and none for a regulation loss.
