When a game is tied after regulation, the next step depends on the sport, competition, and phase of the season. This guide explains the main overtime, extra-inning, extra-time, and tiebreaker formats in American football, basketball, baseball, soccer, and selected college sports, then gives you a practical checklist for identifying the correct rule during a live game.
Overview
“Overtime” is not one universal format. The NFL uses timed possession-based periods, the NBA adds complete five-minute periods, MLB continues with additional innings, and soccer may use extra time followed by a penalty shootout. Some regular-season competitions allow a draw, while playoff games generally require a winner.
The first question is therefore not simply, “Is there overtime?” It is: Which competition is being played, and does that competition require a winner today? A regular-season soccer match may end level after 90 minutes, while a cup final may proceed to extra time and penalties. An NFL regular-season game can have a different overtime procedure from a playoff game. College football also uses a possession-based format that is distinct from the professional game.
Rules can change through official rulebook updates, so use the table below as a practical orientation rather than a substitute for the current league handbook. Broadcast graphics and the competition’s official game center are useful checks when the stakes are high.
Quick comparison
| Sport or competition | Length or structure | How the winner is decided | Regular-season limit | Playoff or knockout note |
|---|---|---|---|---|
| NFL | A timed overtime period; the opening possession is determined by a pregame-style coin toss | Possession and scoring rules determine whether one score ends the game or the other team receives a chance | May have a time limit and can finish tied, depending on the applicable season rules | Postseason games continue through additional periods until a winner is determined, with possession provisions different from some regular-season formats |
| NBA and WNBA | Five-minute overtime periods | The team leading after an overtime period wins; another period follows if still tied | No fixed cap in a completed game | The same repeated-period principle generally applies until a winner is established |
| MLB | Additional innings, each with three outs per team | The game ends after a completed inning or half-inning when one team leads | Extra innings continue until a winner, subject to official game and scheduling rules | Postseason procedures may differ from regular-season runner-placement rules; check the current postseason regulations |
| Soccer | Usually two 15-minute extra-time periods in knockout matches that require a winner | If still level, a penalty shootout may decide the match | Many league matches end as draws after regulation | Competition rules determine whether extra time, penalties, or another tiebreaker is used |
| College football | Alternating possessions beginning near the opponent’s goal line, with later rounds emphasizing two-point attempts | Each team receives the applicable possession opportunity until one leads after an equal set of chances | The format is designed to produce a winner rather than a draw | Later overtime rounds use different scoring requirements; consult the current NCAA rules |
| College basketball | Five-minute overtime periods | The team ahead after an overtime period wins; periods repeat if necessary | No normal completed-game tie | Conference and tournament games generally continue until a winner is determined |
Timeouts, substitutions, clock administration, possession choices, and replay procedures are sport-specific. They should be checked separately rather than inferred from another league.
Checklist by scenario
If you are watching an NFL game
- Identify whether the game is regular season, preseason, or postseason.
- Check the current season’s overtime length and possession rules.
- Watch the coin-toss result and note which team receives the opening possession.
- Determine whether the opening score ends the game or whether the opponent must receive a possession.
- Confirm the remaining game clock, team timeouts, and the rule governing a second overtime period.
If you are watching basketball
- Confirm the league and level; professional and college rules are similar in structure but not identical in administration.
- Expect a five-minute period in the major professional and college formats unless the competition states otherwise.
- Track team fouls, available timeouts, and possession-arrow or jump-ball procedures where relevant.
- If the score remains tied, assume another period is possible rather than a shootout or sudden-death finish.
If you are watching baseball
- Check whether the game is a regular-season contest or a postseason game.
- Note whether a runner begins an extra inning in scoring position under the applicable rules.
- Remember that the visiting team bats first and the home team may win in the bottom half without recording three outs.
- Look for official announcements about a suspended game, weather delay, or roster limitation before assuming the inning will continue normally.
If you are watching soccer
- Identify the competition and whether a draw is an acceptable result.
- Check whether the knockout rules call for extra time after 90 minutes.
- If extra time is used, verify its length and any competition-specific substitution provisions.
- If the score remains level, confirm that a penalty shootout is next and understand that shootout kicks are a tiebreaker, not regular match goals.
If you are watching college football
- Confirm that the game follows the current NCAA format.
- Track which team starts each possession and the number of overtime round.
- Pay particular attention to the transition to required two-point attempts in later rounds.
- Use the official scoreboard or rulebook if a penalty, replay decision, or possession change affects the sequence.
What to double-check
Competition format: A league match, conference tournament, national playoff, and championship final may use different procedures even within the same sport.
Current season rules: Overtime length, possession guarantees, runner placement, substitution limits, and clock rules can be amended. Check the latest official rulebook before relying on an older explanation.
Scoreboard wording: “OT,” “ET,” “SO,” and “XTRA” can refer to different stages. In soccer, “ET” commonly means extra time, while “SO” may indicate a shootout. In baseball, “extras” means additional innings, not a timed period.
What counts as the winning score: A touchdown, field goal, basket, run, goal, successful penalty kick, or two-point conversion can have different consequences depending on the format. Do not assume that the first score always ends the game.
Timeouts and clock status: A timeout does not necessarily stop every part of overtime in the same way. Review the sport’s clock rules, especially after reviews, penalties, possession changes, or end-of-period situations.
Common mistakes
- Calling every tiebreaker overtime: Soccer penalties and baseball extra innings are different mechanisms, even though both resolve a tied result.
- Applying playoff rules to the regular season: This is especially common in the NFL and soccer, where the requirement to produce a winner may change.
- Assuming a five-minute basketball period is sudden death: Basketball normally plays a complete overtime period, with another period if necessary.
- Ignoring the half-inning: In baseball, a home team can end the game during the bottom half as soon as it takes the lead.
- Missing later-round college football rules: The format changes after the early overtime rounds, particularly for two-point attempts.
- Using an undated social-media graphic: A simplified chart may omit the competition stage or reflect an old rule. Prefer an official league or tournament source.
When to revisit
Use this guide whenever you watch an unfamiliar league, enter a playoff game, or need to explain a tied score during a live sports update. Recheck it before each season, after an official rule change, and when a tournament publishes new competition regulations. The most important details to verify are overtime length, possession order, regular-season limits, shootout procedures, timeout rules, and whether later rounds use a different scoring format.
For a reliable live-game workflow, save the competition’s official rules page, identify the game stage, read the scoreboard’s overtime label, and then confirm the next possession or period. Once those four checks are complete, compare the situation with the sport-specific checklist above.
