Overtime (sports)
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 where the scores are the same. In some sports, this extra period is played only if the game is required to have a clear winner, as in single-elimination tournaments where only one team or players can advance to the next round or win the tournament and replays are not allowed.

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 terms overtime and in overtime (abbreviated "OT") are primarily used in North America, whereas the terms extra time and after extra time (abbreviated "a.e.t.") are usually used in other continents.
Association football [edit]
Knock-out contests (including professional competition)[edit]
In association football knockout competitions or competition stages, teams play an extra 30 minutes, called extra time, when the deciding leg (or replay of a tie) has not produced a winner by the end of normal or full-time. It follows a short break (traditionally five minutes) where players remain on or around the field of play and comprises two 15-minute periods, with teams changing ends in between. Although the Laws of the Game state that extra time is one of the approved methods to decide a winner, competitions are not bound to adopt extra time, and each competition is free to choose any method designated in the Laws of the Game to decide a winner.
In a one-off tie or deciding replay, level scores nearly always go to extra time but this only applies to the FIFA competitions and the first-tier continental national team competitions. In games played over two legs at the continental levels (such as the three–tier men's continental club competitions and the women's continental club competitions), domestic levels (such as Copa del Rey, DFB-Pokal and the Coppa Italia semi-finals or Bundesliga relegation and promotion play-offs) or even at lower levels (such as the English Football League play-offs), 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, however starting the 2021–22 season, UEFA decided to abolish it for all club competitions and changed with the penalty shootout if the aggregate is still tied after the extra time. Ties in the 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 or shootouts though, nowadays, replays are limited to just one with the game going to extra time if teams are still level. Equally, CONMEBOL has historically never used extra time in any of the competitions it directly organizes except only in the final match of a competition, such as the Copa Libertadores and Copa Sudamericana. 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. The two-legged format for the club competition finals with this rule is still used in AFC[a 1] and CONCACAF club competitions where an away goals rule still takes place.
Ties that are still without a winner after extra time are usually broken 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. The term "asdet" refers to the result of a penalty shootout "after sudden death extra time" and after the away goal rules abolished by UEFA, all sanctioned club competitions decide the knockout ties with the penalty shoot-out in the 2021-22 season if the aggregate remains unchanged after the 15-minute extra time.
Basketball[edit]
In basketball, if the score is tied at the end of regulation play, the teams play multiple five-minute overtime periods until a winner is decided. 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. The alternating possession rule is used to start all overtime periods under international rules for full-court basketball,[12] 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 Women's National Basketball Association, which uses a quarter-possession rule to start periods after the opening jump, also uses a jump ball.[13][14][15] The entire overtime period is played; there is no sudden-death provision. 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, this procedure is repeated until a winner is determined.
As many as six overtime periods have been necessary to determine a winner in an NBA game.[16]
In exhibition games (non-competitive play), it is upon the discretion of the coaches and 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.[17] Euroleague Basketball 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, and the two-legged tie. Although other competitions use two-legged ties at various stages, the FIBA Europe competitions are the only ones known to use overtime only if the aggregate score after the second game is tied.
A rule change in the FIBA rules effective 1 October 2017 (Article D.4.2) permits drawn games at the end of either leg of the two-legged tie. The definition states, "If the score is tied at the end of the first game, no extra period shall be played."
In The Basketball Tournament, a 64-team single-elimination tournament held each summer in the U.S. with a $1 million winner-take-all prize, no overtime is played since 2018. Games employ the "Elam Ending", named after its creator, Ball State University professor Nick Elam, with the idea of making sure the game always ends on a basket.[18] Upon the first dead ball (time-out, foul, violation) with 4 minutes or less remaining in the fourth period, the game clock is turned off (though the shot clock remains active). A target score is set at the current lead score plus eight points (originally seven, but changed for the 2019 edition), and the first team to reach or surpass the target wins.[19] The NBA All-Star Game had used the Elam Ending from 2020 to 2023. The fourth period had no game clock, but the shot clock was active. Instead, a target score is set at the leading score after three periods plus 24 points; the first team to reach or exceed that score by any legal basket (field goal, three-pointer, or free throw) wins the game. The Canadian Elite Basketball League first used the Elam Ending in a 2020 tournament that replaced the season that was scrapped due to COVID-19, using TBT rules except that the target score was set by adding 9 points instead of 8. The CEBL made this permanent starting with its 2021 season.
Starting in 2022–23, the NBA G League adopted a variation of the Elam Ending in regular-season games, calling it the "Final Target Score". Instead of replacing overtime, the G League is using the Elam Ending as its overtime format. In this implementation, the target score is set by adding 7 points to the tied teams' score. The teams then play with a shot clock but no game clock, with the game ending once the target score is reached or exceeded. For the G League Winter Showcase, an event held in December in Las Vegas that sees all 30 teams play two games, the Elam Ending is implemented in the same manner as in the NBA All-Star Game, except the target score is the leading score plus 25 (instead of 24).[20]
In 3x3 basketball, a formalized version of the half-court three-on-three game, ties after a 10-minute game are settled by continuing play with no game clock (only the shot clock) until one team scores two additional points: baskets made outside the arc being worth two points and all others being worth one point. The 21-point rule, under which a regulation game ends once either team has reached 21 points, does not apply during overtime; a tie at 20 must go to 22. The team that did not get first possession in the game gets first possession in overtime (as jump balls are not used in 3x3). Individual personal foul counts are not kept at any time during the game; all personal fouls are recorded against the team, and team fouls carry over to overtime.[21]
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.
