Overtime in Basketball

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.

Overtime (OT) or extra time is an additional period of play 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.

At the start of overtime, the team captains and officials hold another coin toss. Similarly to the coin toss at the beginning of the game, the team that wins the coin toss chooses whether they want to receive or kick the opening kickoff, while the other team chooses which end of the field they will defend. Gameplay is conducted similarly to the regulation periods (in contrast with the "Kansas system" used in college football rules), and each team is given two timeouts. Instant replay reviews must be initiated by the replay official, i.e. there are no challenges.

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.
