In a sport or game, sudden death (also sudden-death, sudden-death overtime, or a sudden-death round) is a form of competition where play ends as soon as one competitor is ahead of the others, with that competitor becoming the winner. Sudden death is typically used as a tiebreaker when a contest is tied at the end of regulation (normal) playing time or the completion of the normal playing task.
An alternative tiebreaker method to sudden death is to play an extra, shortened segment of the game. In association football 30 minutes of extra time (overtime) after 90 minutes of normal time, or in golf one playoff round (18 holes) after four standard rounds (72 holes) are two alternatives. Sudden death playoffs typically end more quickly than the shortened play alternative. Reducing the variability of the event's duration assists those scheduling television time and team travel. Fans may see sudden death as exciting and suspenseful, or they may view the format as compromising the sport, compared to play during regulation time. For example, prior to 2012, the National Football League (American football) used a sudden-death rule that encouraged the team possessing the ball to just kick a field goal to end the game rather than striving to score a touchdown.
