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, particularly those prominently played in North America where ties are generally disfavored, some form of overtime 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.
Association football 
Knock-out contests (including professional competition) 
In football (soccer) knock-out competitions or competition stages, teams play an additional 30 minutes, which is called extra time, in case the deciding leg (or replay of a tie) has not produced a winner by the end of regulation or full-time. Extra time is governed by the rules of the tournament, rather than the laws of the game. It follows a short break where players remain on or around the field of play and comprises two 15-minute periods, with teams changing ends in between. In a one-off tie or deciding replay, level scores nearly always go to extra time. Over two legs, teams only play extra time in the second leg where the aggregate score – then normally followed by an away goals rule – has not produced a winner first. The score in games or ties resorting to extra time are often recorded with the abbreviation a.e.t. (after extra time), usually accompanying the earlier score after regulation time.
Not all knock-out competitions always employ extra time. For example, ties in many competitions are played over two legs (such as the UEFA Champions League or World Cup qualification intercontinental play-offs), one at each competing team's 'home' stadium. Extra time in such competitions is only played at the end of the second leg should the tie still be undecided. Meanwhile ties in the English FA Cup used to be decided by as many replays as necessary until one produces a winner within normal time, rather than have any extra time (and/or shootout). Nowadays replays are limited to just the one, however, with the second going to extra time if teams are still level. Equally, 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).
Ties that are still without a winner after extra time are usually decided by kicks from the penalty spot, commonly called a penalty shootout. In the late 1990s and early 2000s, many international matches tried to reduce this by employing the golden goal (also called "sudden death") or silver goal rules (the game ending if a team has the lead after the first 15-minute period of extra time), but competitions have not retained these.
US High school rules 
High school rules vary depending on the state and conference, but most will have a sudden-death overtime procedure wherein the game ends upon scoring a golden goal, although in some instances the overtime will go until completion with the team in the lead after time expires (i.e., silver goal rules) declared the winner. The overtime period length may vary, but it is commonly 10 minutes long. Depending on the state, if the game is still tied at the end of the first overtime:
- As many additional overtime periods – golden or silver goal rules – may be played as needed to determine a winner.
- After one or more overtime periods result in the score remaining tied, a shootout procedure may be played. In a shootout, the coaches and/or team captains select five players to shoot penalty kicks, with teams alternating kicks from the penalty mark in an attempt to put the ball into the net. The procedure continues until each team has taken five kicks, or if one side has scored more successful kicks than the other could possibly reach with its remaining kicks.
- If both teams make the same number of successful penalty kicks after all eligible players have taken their first kick, the procedure repeats; the teams are not required to follow the same order of kickers as was used for the first kick, and may replace one or more of the original kickers. The procedure repeats until one side has successfully converted more penalty kicks in a set of five attempts.
- Depending on the state or conference, the game may go directly to a penalty shoot-out, rather than playing overtime.
American and Canadian football 
The NFL introduced overtime for any divisional tiebreak games beginning in 1940, and for championship games beginning in 1946. The first postseason game to be played under these rules was the 1958 NFL Championship Game between the Baltimore Colts and New York Giants (the so-called "Greatest Game Ever Played"). 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. Under the original regular season format used through 2011, the first team to score during the extra period won the game. Additionally, during regular season games, fourth quarter timing rules were in effect throughout the period. This included a two-minute warning if necessary. In the regular season, if the overtime period was completed without either side scoring, the game ended in a tie. Because there cannot be a tie in the playoffs, the teams would switch ends of the field and start multiple 15-minute overtime periods until one side scored. Additionally, all clock rules were as if a new game had started. Therefore, if a game was still tied with two minutes to go in double (or quadruple) overtime, there would be a two-minute warning (but not during the first overtime period as in the regular season). If it were still tied at the end of double overtime, the team that received the kickoff to start overtime would kick off to begin triple overtime. Presumably, there would be a second coin flip to begin quintuple overtime, but this is unconfirmed and highly unlikely to ever happen. 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 on Christmas Day 1971. The longest in all of modern professional football is a 1984 United States Football League playoff game, also using the true sudden death rule, in which the Los Angeles Express defeated the Michigan Panthers 27–21 in triple overtime.
As a consequence of the 1974 rule changes, the number of tie games dropped dramatically. Only 18 NFL games have ended in a tie since then, and just five since 1990. The most recent was on 11 November 2012 when the St. Louis Rams tied with the San Francisco 49ers 24-24.
Scoreless ties were common in the early years of the NFL, but none has happened since 1943.
In March 2010, the NFL amended its rules for postseason overtime after a vote by the team owners, with the rule being extended into the regular season in March 2012. If the team that receives the kickoff scores a touchdown; or if the defence scores a safety on its first possession, it is declared the winner. If it scores a field goal on its first possession, however, it then kicks off to the opposing team with an opportunity to score; if the score is tied again after that possession, true sudden death rules apply and the next team to score by any method is declared the winner. If both teams are still tied after the OT there will be another overtime period played, and that procedure is repeated until a winner is declared, unless it's a regular season game, which would simply end in a tie. There were no overtime games in the 2010 posteason, so the first implication of this rule came in the wild-card round in 2011. Incidentally, this was also the shortest overtime in NFL history. Pittsburgh Steelers kicker Shaun Suisham kicked off and the ball went out of the back of the end zone, resulting in a touchback and no time off the clock. Tim Tebow, then with the Denver Broncos, threw an 80-yard touchdown pass on the first play to Demaryius Thomas to give the Broncos the win in only 11 seconds.
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).
The New York Pro Football League, a 1910s-era league that eventually had several of its teams join the NFL, used the replay to settle ties in its playoff tournament. The replay was used in the 1919 tournament to decide the championship between the Buffalo Prospects and the Rochester Jeffersons had played to a tie on Thanksgiving; Buffalo won the replay 20–0 to win the championship.
College, high-school, and Canadian football 
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, or turns over the ball (either on downs or by the defense otherwise gaining possession). As usual, a touchdown by the offense is followed by a try for one or two points. In NCAA football, starting in triple overtime, teams must attempt a two-point conversion after a touchdown. Since 2010, CFL teams must also attempt the two-point conversion after any touchdown in overtime.
- In college football the defense may score a touchdown on a play on which it gains possession by turnover; such a play will satisfy the condition of each team having a possession and will therefore end the game. 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. If scoring is not allowed or the turnover play does not end with a score, regardless of the eventual position of the ball at the end of the play, the team assumes offense and will begin their procedure from the specified position on the field.
- 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, multiple overtime procedures are 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 26 September 2002, when Louisville defeated Florida State 26–20, and 27 September 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 9 September 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.
An alternate overtime method to the Kansas Playoffs occasionally used at the high school level is the California playoff.
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 (a rule imposed to prevent teams from turning the overtime period into the equivalent of a penalty shootout). Although such a scenario never happened in the league's short life, the XFL rules did not explain what would happen should a turnover occur and the set of four downs end prematurely. 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 multiple five-minute overtime periods. 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. 3x3 (originally FIBA 33), a formalized version of the halfcourt three-on-three game, uses an untimed overtime (the former FIBA 33 rules called for two-minute 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 and the WNBA, 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 3x3, in which the game ends once either team has scored 2 points in overtime, with baskets made from behind the "three-point" arc worth 2 points and all other successful shots worth 1 point. 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, multiple overtime periods are 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, Euroleague Basketball, 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. Euroleague Basketball (company) 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 Euroleague Basketball (company) competitions are the only ones known to use overtime only if the aggregate score after the second game is tied.
Ice hockey 
Ties are common in ice hockey due to the game's low-scoring nature. 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 five-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; no player may participate in a shootout twice unless the entire active roster (excluding the backup goaltender) has been exhausted, which so far has never happened. 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; it also differs in that if the shootout does not resolve the tie, the same five skaters then shoot again). 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.
Team handball 
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 softball 
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 as many extra innings as are needed to determine a winner. Complete innings are played, so if a team scores in the top half of the inning, the other team has the chance to play the bottom half of the inning. The longest professional baseball game ever played, a 1981 minor league baseball game between the Pawtucket Red Sox and the Rochester Red Wings required 33 innings and over eight hours to complete. The Red Wings had scored in the top half of the 21st inning, but Pawtucket tied the game in the bottom half, extending the game.
Major League Baseball games normally only end in a tie if the match is called off due to weather conditions. In the early decades of baseball (up to the 1920s), a game could also be called off due to nightfall, but this ceased to be a problem once stadiums began installing lights in the 1930s. Two Major League Baseball All-Star Games have ended in a tie; the second 1961 game was called due to rain with the teams tied 1-1 after the ninth inning, and the 2002 game was called after the eleventh inning after both teams had exhausted their supply of pitchers.
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 
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.
Other sports 
- In Australian rules football, extra time is played only in finals matches. Two extra time periods lasting five minutes each (plus time on) are played. The only exception is the AFL Grand Final, which is decided by a full replay if the match is drawn; extra time is played if the replay is also drawn.
- In Gaelic football and hurling, two halves of ten minutes are played after a draw. In major Gaelic football tournaments, multiple sudden death periods of this procedure will continue until one team scores, which wins them the match.
- In futsal matches, two overtime periods of 5 minutes each are played, with teams changing ends in between. If the teams are still tied after the overtime, there takes place a penalty shootout.
- In water polo, if the score is tied at the end of regulation play, two overtime periods of three minutes each are 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. Some One Day International tournaments (including the 2011 World Cup) have also introduced the 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 (multiple two 7-minute extra time periods) 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 a winner.
- In Touch Football under the Federation of International Touch structure, finals matches that are drawn at full-time progress into an extra time period known as a "Drop-Off". During a drop-off, each team reduces their on-field playing strength by one (1) player every two (2) minutes, until teams are down to three (3) players. Both teams must have had possession of the ball before a result can be declared.

American football 
- Six National Football League playoff games have gone into a second overtime, the longest being an AFC divisional playoff game on 25 December 1971. The Miami Dolphins defeated the Kansas City Chiefs, 27–24 at 7:40 into the second overtime (at 82:40 of total play, the longest game in NFL history; the length of the game coupled with the fact that it was played on Christmas Day led to a great deal of controversy and the league placing an 18-year moratorium on Christmas games). The most recent 2OT NFL game came in an AFC divisional playoff game on 12 January 2013, with the Baltimore Ravens defeating the Denver Broncos 38–35 on a field goal at 1:42 in the second overtime.
- In the former American Football League, the championship game played on 23 December 1962 went two overtimes, with the Dallas Texans defeating the Houston Oilers 20–17, on a 25-yard field goal at 2:54 into the second overtime. (This game, along with all other AFL games, were incorporated into the NFL record books following the 1970 merger of the two leagues.)
- The former United States Football League had a triple-overtime playoff game on 30 June 1984. The Los Angeles Express defeated the Michigan Panthers, 27–21, on a walk-off touchdown 3:33 into the third overtime (at 93:33 of total play, the longest professional football game ever played in the United States).
- Collegiate (NCAA Division I FBS, formerly Division I-A) – Three games have gone to seven overtimes. On 3 November 2001, the Arkansas Razorbacks beat the Mississippi (Ole Miss) Rebels 58–56 in seven overtimes; the game had been tied 17–17 after four quarters. On 1 November 2003, Arkansas beat the Kentucky Wildcats 71–63, also in seven overtimes; the score was tied 24–24 at the end of regulation play.

- High school – 29 October 2010: Jacksonville High School (TX) defeated Nacogdoches High School (TX) by a score of 84-81 after 12 overtimes. Nacogdoches could have won in earlier overtime periods, but needed a win by 8 points to keep its postseason hopes alive and so intentionally forced additional overtime periods rather than win by fewer than 8 points.
Ice hockey 
- NHL – 23 March 1936: The Detroit Red Wings beat the Montreal Maroons 1–0 in the 6th overtime and after a total of 116:30 minutes had been played in overtime.

Rugby league 
The longest rugby league game at senior level is 104 minutes, during the 1997 Super League Tri-series final between NSW and QLD. Normal game time is 80 minutes, but with scores level a further 20 minutes was played. When the scores remained level after 100 minutes, golden point extra time was invoked, a Noel Goldthorpe field goal decided the game after 104 minutes.
