Overtime or extra time is an additional period of play specified under the rules of a sport to bring a game to a decision and avoid declaring the match a tie or draw. In most sports, this extra period is only played if the game is required to have a clear winner, as in single-elimination tournaments where only one team or player per match can advance to the next round. In other sports, particular those prominently played in North America where draws are generally disfavored, some form of extra time is employed for all games.
The rules of overtime or extra time vary between sports and even different competitions. Some may employ "sudden death", where the first player or team who scores immediately wins the game. In others, play continues until a specified time has elapsed, and only then is the winner declared. If the contest remains tied after the extra session, depending on the rules, the match may immediately end as a draw, additional periods may be played, or a different tiebreaking procedure such as a penalty shootout may be used instead.
The term "overtime" is primarily used in North America, whereas "extra time" is used in other continents.
Professional association football play an extra 30 minutes, made up of two 15-minute periods. Not all competitions employ extra time; for example, CONMEBOL has historically never used extra time in any of the competitions it directly organises, such as the Copa Libertadores (today, it uses extra time only in the final match of a competition). If such a game is still tied after extra time it is usually decided by kicks from the penalty spot, commonly called a penalty shootout. If the score remains level after extra time, the game is determined by a penalty shootout and the winning penalty shootout team are declared winners.
American and Canadian footballEdit
The NFL introduced overtime for the playoffs in 1941, and started in pre-season games in 1955. In 1974, the NFL adopted sudden death overtime for regular season games. If the score is tied after regulation time has concluded, an additional 15-minute period is played. The captains meet with the officials for a coin toss, and then one side kicks off to the other, as at the start of a game. The first team to score during the extra period wins the game. In the regular season, if the overtime period is completed without either side scoring, the game ends in a draw. Because there cannot be a tie in the playoffs, the teams switch ends of the field and start additional 15-minute overtime periods until one side scores. The longest NFL game played to date is 82 minutes, 40 seconds (and the Chiefs' last-ever game at Municipal Stadium), Miami kicker Garo Yepremian kicked the winning 37-yard field goal after 7:40 of double-overtime in the 1971–72 NFL playoffs.
"In March 2010, the NFL amended its rules for overtime after a vote by the team owners. If the team that wins the coin toss scores a touchdown on their first possession, they are declared the winner. If they score a field goal on their first possession, however, the opposing team is given possession of the ball and an opportunity to score(in postseason); if the score is tied again after that possession, sudden death rules apply and the next team to score by any method is declared the winner, and the number of additional 15 minute periods will not matter. If neither team scores there will be another overtime period to be played before resulting in a tie (with exception of postseason, when the game will be played until a winner is declared). The rule change currently applies to postseason games."
The Arena Football League and NFL Europa used a variant in which each team is guaranteed one possession. Whoever is leading after one possession wins the game; if the teams remain tied after one possession, the game goes to sudden death. This procedure was used by the United Football League in its inaugural 2009 season.
The short-lived World Football League, for its inaugural 1974 season (the same year the NFL established sudden death in the regular season), used extra time (one full fifteen-minute quarter, divided into two halves).
College, high-school, and Canadian footballEdit
In college (beginning with the 1996 season) and high school football, as well as the Canadian Football League, an overtime procedure is used to determine the winner. This method is sometimes referred to as a "Kansas Playoff," or "Kansas Plan" because of its origins for high school football in that state. A brief summary of the rules:
- A coin toss determines which side shall attempt to score first, and at which end zone the scores shall be attempted.
- Each team in turn will receive one possession (similar to innings in baseball), starting with first-and-10 from a fixed point on the opponent's side of the field:
- In college football, the possession begins at the opponent's 25-yard line.
- In high school football, the ball begins at the 10-yard line, with the option for state high school associations to use different yardage (such as the 15, 20, or 25-yard line)
- In the CFL, where a single point can be scored on a punt, the 35-yard line is used.
- The game clock does not run during overtime; the play clock, however, is enforced.
- A team's possession ends when it scores (touchdown or field goal), misses a field goal, fails to gain a first down on the final down, or loses the ball by turnover. As usual, a touchdown by the offense is followed by a try for one or two points. (In NCAA football, starting in the third overtime, teams cannot kick a field goal to score an extra point after a touchdown. Starting in 2010, CFL teams cannot kick a field goal to score an extra point after any touchdown in overtime.)
- In college football the defense may score on a play on which it gains possession by turnover. In high school football, the defense is generally not allowed to score if it gains possession, although the Oregon School Activities Association adopted the college rule experimentally in 2005, and the University Interscholastic League of Texas, the Texas Association of Private and Parochial Schools, and the Massachusetts Interscholastic Athletic Association use NCAA football rules.
- Each team receives one charged time-out per overtime procedure (except in the CFL).
- If the score remains tied at the end of the overtime procedure, an additional overtime procedure is played. The team with the second possession in one overtime procedure will have the first possession in the next overtime procedure.
- In the CFL there is a limit of two overtime procedures in regular-season games (after which the game is a tie), but no limit in playoff games. In American college and high school football, the overtime procedures are continued until a winner is determined.
On two occasions, just two plays were required to determine an overtime winner in an NCAA football game. These occurred on September 26, 2002, when Louisville defeated Florida State 26–20, and September 27, 2003 when Georgia Tech defeated Vanderbilt 24–17.
It is possible for a college game to end after a single play in overtime if the team on defense secures a turnover and returns it for a touchdown. (One example of a defensive touchdown ending the game occurred on September 9, 2005 when Ohio defeated Pittsburgh 16–10 on an 85 yard interception return by Dion Byrum; this occurred on the third play of overtime.) Furthermore, it is possible (but not likely) that the defense may get a safety on the first possession in overtime, thus ending the game after only one overtime play. Because this would require the offense to go backward 75 yards, this is extremely improbable and has never happened in FBS.
The short-lived XFL used a modified Kansas Playoff, where the series would start on the 20-yard line and have four downs to score. However, if the first team to play overtime scored a touchdown in less than four downs, the second team would have to score in just as many plays (for instance, if the first team scored a touchdown on three downs, the second team would only have three downs to score a touchdown). Neither team could kick a field goal until the fourth down. Rather than a coin toss, the winner of the opening scramble at the beginning of the game also got to choose to go first or second in overtime.
In basketball, if the score is tied at the end of regulation play, the teams play a five-minute overtime period. In levels below collegiate/Olympic play, an overtime period is half the length of a standard quarter, i.e., four minutes for high school varsity. FIBA 33, a formalized version of the halfcourt three-on-three game, uses two-minute overtime periods. The alternating possession rule is used to start all overtime periods under international rules while a jump ball is used under high school and NCAA rules, with the arrow reset based on the results of the jump ball to start each overtime. The National Basketball Association, which uses a quarter-possession rule to start periods after the opening jump, also uses a jump ball. The entire overtime period is played; there is no sudden-death provision. The only exception is in FIBA 33, in which the game ends by rule once either team has scored at least 33 points. All counts of personal fouls against players are carried over for the purpose of disqualifying players. If the score remains tied after an overtime period, an additional overtime period is played.
As many as six overtime periods have been necessary to determine a winner in a NBA game.
In exhibition games (non-competitive play), it is upon the discretion of the coaches and/or organizers if an overtime is to be played, especially if it is a non-tournament game (a one-off event).
Starting in the 2009–10 season, ULEB, the organizer of the Euroleague and Eurocup, introduced a new rule for two-legged ties that eliminated overtime unless necessary to break a tie on aggregate. The rule was first used in the 2009–10 Eurocup quarterfinals (which consist of two-legged ties), although no game in that phase of the competition ended in a regulation draw. ULEB extended this rule to all two-legged ties in its competitions, including the Euroleague, in 2010–11. One game in the qualifying rounds of that season (the only phase of the Euroleague that uses two-legged ties), specifically the second leg of the third qualifying round tie between Spirou Charleroi and ALBA Berlin, ended in a draw after regulation. No overtime was played in that game because Spirou had won the first leg. Although other competitions use two-legged ties at various stages, the ULEB competitions are the only ones known to use overtime only if the aggregate score after the second game is tied.
In ice hockey, if the score is tied at the end of regulation play, certain leagues play overtime.
- NHL (regular season): If a game is tied after regulation time (three 20-minute periods), the teams play in a sudden death 5-minute overtime period, with a goaltender and four skaters per side (as opposed to the standard five). If nobody scores in the overtime period, the teams engage in a "penalty shootout" where 3 skaters, selected by the head coaches on the teams, go one-on-one against the opposing goaltender, taking the puck at center ice for a "penalty shot." If the shootout remains tied after the initial 3 rounds, the shootout continues in a sudden-death fashion. The greatest number of shooters in a single shootout was 30 during a game between the New York Rangers and Washington Capitals. Rangers defensemen Marek Malik gave New York a 3–2 shootout and game victory on a trick move.
The 5-minute overtime period was introduced for regular season games beginning with the 1983–84 NHL season, but with teams at full strength on the ice. Overtime in the regular season was reduced to four skaters a side starting in the 2000–2001 season. The "shootout" was introduced for the 2005–06 NHL regular season.
- NHL (post-season): Following an intermission, an additional full 20-minute period is played. Teams remain at full strength unless this is affected by penalties during the third period. A goal ends the game in sudden death; if neither team scores, another intermission is taken, followed by an additional overtime period. The teams change ends of the ice for each period. This has made for lengthy games in the history of the NHL playoffs, with some games going as far as five or six overtimes before the deciding goal is scored.
- NCAA (regular season): If a game is tied at the end of regulation, the teams play a sudden-death 5-minute overtime. Both teams play at full strength, unless affected by penalties. If neither team scores during overtime, the game ends in a tie.
- NCAA (in-season tournaments): For tournaments held during the season (such as the Beanpot and Great Lakes Invitational), in which advancement or determination of a champion is necessary, organizers have the option of either using the post-season overtime procedure or using the regular-season procedure followed by a penalty shootout. Statistics from a shootout are not counted by the NCAA, and a game decided by a shootout is considered a tie for NCAA tournament selection purposes.
- NCAA (post-season): Same as the NHL overtime procedure above, except that all overtimes are played with the teams defending the same ends as for the third period. Games decided in overtime are considered wins or losses rather than ties, regardless of how many overtimes are played.
- International (round robin): As of the 2007 IIHF World Championships, the IIHF instituted the "three point rule", which not only awarded the winning team three points for a regulation win, but awarded them two points for a win in a 5 minute overtime period or a Game Winning Shot (shootout). Games in IIHF round robins can therefore no longer end in a tie. In the World Cup of Hockey in 2004, the NHL's tiebreaking procedure at the time was followed: there was a five-minute sudden death period at four skaters per side, and if the score remained tied after the overtime period, it stood as a tie. The game between Sweden and Finland ended in a 4–4 tie after 65 minutes.
- International (medal rounds): Various tiebreaking procedures have been used for international tournaments, with all of them save one (World Cup of Hockey 2004) following a common theme: one period varying in length of sudden-death overtime followed by a shootout of five skaters per side (as opposed to the NHL's three skaters per side). The length of the overtime period has varied between 5, 10, and 20 minutes, and 5-on-5 and 4-on-4 formats have been used. The most recent format used was at the 2010 Olympics (particularly in the gold medal game); there were 20 minutes of 4-on-4 followed by a shootout. In 2006, it was 20 minutes of 5-on-5. All men's games ended in regulation during the medal rounds, while the women's semifinal between the United States and Sweden required a shootout to determine the winner. At the World Cup of Hockey in 2004, the NHL's postseason tiebreaking procedure was used (multiple 20-minute periods of 5-on-5 until a goal is scored). The only overtime game in the playoff round was the semifinal between the Czech Republic and Canada. Canada won 4–3 with a goal 2 minutes and 16 seconds into the first overtime period.
- When a tie needs to be broken in team handball, an overtime period of 2x5 minutes is played. If the teams are still tied after that, another overtime period of 2x5 minutes is played.
- If the teams are still tied after the latter period, there takes place a penalty shootout.
Baseball and softballEdit
Baseball and softball are unique among the popular North American team sports in that they do not use a game clock. However, if the regulation number of innings are complete (normally nine in baseball and seven in softball) and the score is even, the game continues for multiple extra innings as are needed to determine a winner. The only exception to this is in Nippon Professional Baseball, where the game ends in a draw after 12 innings if the score is tied. Ties are allowed to stand in the regular season; postseason ties (which happen after 15 innings) must be replayed in their entirety.
Rugby league games in some competitions are decided using overtime systems if scores are level at full time (80 minutes). One overtime system is golden point, where any score (try, penalty goal, or field goal) by a team immediately wins the game. This entails a five minute period of golden point time, after which the teams switch ends and a second five minute period begins. Depending on the game's status, a scoreless overtime period ends the game as a draw, otherwise play continues until a winner is found.
- In the AFL finals system of Australian rules football, two five-minute extra time periods are played in knockout finals matches when scores are tied at the end of the final quarter. The final AFL game, the AFL Grand Final, is replayed in the event of a tie at the end of regulation. If the replayed AFL Grand Final is also a tie, the extra time rules used during the finals series will be used.
- In Gaelic football (and hurling), two halves of ten minutes are played after a draw. In major Gaelic football tournaments, extra time is only used if a replay finishes in a tie.
- In field hockey matches, extra time of 7½ minutes each way is played.
- If a game of curling is tied at the end of its prescribed number of rounds (called ends), extra ends are played until there is a winner.
- Ties are allowed to stand in most forms of cricket, but Twenty20 cricket provides for tiebreaker procedures should a winner be necessary (such as in tournament settings): a limited extra session called a Super Over.
- In netball matches, two seven minute periods are played with no break between periods. If the scores are still tied after this period, the match continues uninterrupted until one side is leading by two goals and are declared the winners. This is known as double overtime should a match end this way. All ANZ Championship matches, Commonwealth Games finals and Netball World Championship finals implement this tiebreaker to ensure of a winner.
