Overtime is one of the most exciting parts of American football, but it can also be confusing—especially because the NFL and college football use very different systems. If you have ever switched between a Saturday college game and a Sunday NFL matchup and thought, “Wait, why are they starting at the 25?” or “How can the NFL end in a tie?” you are not alone. This guide breaks down the key differences between NFL and college overtime rules in clear, beginner-friendly language. You will learn how each format starts, how teams can win, what changes in the playoffs, and the strategies that coaches use to gain an edge.
Quick snapshot: What makes NFL and college overtime different
In the NFL regular season, overtime is one timed period with a kickoff and normal drives. It can end in a tie if no one wins by the end of the period. In the NFL playoffs, overtime expands, and both teams are guaranteed a possession before sudden death begins.
In college football, overtime is not timed by a game clock. There are no kickoffs. Instead, teams alternate possessions starting at the opponent’s 25-yard line. After a touchdown in the second overtime, a two-point try is mandatory. Starting with the third overtime, teams alternate two-point conversion attempts only—no full drives.
Those basic differences shape everything else: how coaches decide the coin toss, what plays they call, how aggressive they are on fourth down, and how much kickers matter. Now, let’s walk through each piece step by step.
How overtime starts
The coin toss in the NFL
The NFL begins overtime with a coin toss. The visiting team calls heads or tails. The winner of the toss chooses to receive the kickoff, to kick, or which goal to defend. In most regular-season situations, the winner almost always chooses to receive, because a touchdown on the opening drive can end the game immediately. In the playoffs, where both teams are guaranteed a possession, the choice can be more strategic, but most teams still prefer to receive first.
The coin toss in college
College overtime also starts with a coin toss, and the visiting captain calls it. The winner chooses one of two things: to play offense first or defense first, or which end of the field to use. The other team gets the remaining choice. Most teams pick to play defense first. Why? Because knowing the opponent’s result (touchdown, field goal, or no points) makes it easier to match or beat it when you get the ball.
Unlike the NFL, there is no kickoff in college overtime. The offensive team simply starts its possession at the opponent’s 25-yard line. In the next overtime, the order of offense and defense switches automatically, so both teams get a turn going first over time.
Why these choices matter
In the NFL regular season, the first possession can be the whole ballgame if it ends with a touchdown. That makes the opening kickoff extremely valuable. In college, the value often lies in going second so you can play to the exact target you need (a field goal to tie, a touchdown to win, or perhaps a riskier fourth-down try based on what the first team did).
Structure and length of overtime
NFL regular-season overtime: short and timed
In the regular season, the NFL plays one overtime period that lasts up to 10 minutes. The standard game clock runs. If either team is ahead when the clock runs out, that team wins. If the game remains tied after the 10-minute period, the game ends as a tie. Each team gets two timeouts in overtime, and replay reviews are initiated by the replay official; coaches cannot challenge in overtime.
NFL playoff overtime: longer and designed to find a winner
In the playoffs, the NFL cannot end a game in a tie, so the format is built to continue until there is a winner. Each overtime period is 15 minutes, and the game will continue into multiple overtime periods if needed. Importantly, each team is guaranteed one possession in playoff overtime, even if the first team with the ball scores a touchdown. If the game is still tied after each team has had one possession, the format shifts to sudden death: the next score wins. Regular timing and replay rules apply, with additional timeouts allotted across multiple overtime periods.
College overtime: untimed series, not a period
College overtime does not use a game clock at all. Instead, teams take turns trying to score from the 25-yard line. One overtime “period” consists of both teams getting one possession from the 25. If the score is still tied after both teams have had their turn, a new overtime begins with the order of offense/defense reversed and typically at the other end of the field. This continues until there is a winner, with special conversion rules kicking in from the second overtime onward.
Possession rules and how you can win
NFL regular season: modified sudden death
Here’s the core regular-season NFL rule: if the team with the ball first scores a touchdown on that opening drive, the game ends immediately. If they kick a field goal, the other team gets the ball and a chance to match or beat that field goal. If the second team also kicks a field goal, the game becomes sudden death—next score wins. If the second team scores a touchdown in response to the first team’s field goal, the second team wins. If the defense scores a touchdown or safety at any time, the game ends immediately.
This structure is why winning the coin toss is a big deal in the regular season. One great opening drive can finish the contest without the other offense touching the ball.
NFL playoffs: both teams get a turn
In the playoffs, the NFL changed its overtime rules so that both teams are guaranteed one possession. If Team A receives the kickoff and scores a touchdown, Team B still gets a possession. If Team B matches with a touchdown, the game moves to sudden death. If Team B fails to match (for example, they kick a field goal or come up empty), Team A wins. If the defense scores a touchdown or safety on Team A’s first possession, the game ends immediately, because a scoring play by the defense ends the contest on the spot.
College: alternating drives from the 25-yard line
In college football, the first overtime begins with Team A either on offense or defense (based on the coin toss choice). The offense starts first-and-10 from the opponent’s 25. They can gain first downs and run a normal drive, but the field is short. If they score a touchdown, they can kick an extra point or try for two—except in later overtimes when rules change. After their possession ends, Team B gets its turn from the 25. If the score is still tied, a second overtime begins with the order reversed.
Because both teams get equal chances from the same field position, ties cannot persist forever. This format also removes kickoffs and long returns from the equation, putting the focus squarely on offense vs. defense from a set distance.
Two-point rules and the college shootout
College overtime adds two key twists to end games faster and reduce the number of plays:
First, starting in the second overtime, teams must attempt a two-point conversion after a touchdown. No extra-point kicks are allowed from that point.
Second, starting with the third overtime, teams no longer run full possessions from the 25. They take turns running a single two-point conversion play from the three-yard line. Team A tries its two-point play. Then Team B tries. If both succeed or both fail, another “round” begins. This continues until one team converts and the other does not.
Defensive scores in overtime
In the NFL, a defensive touchdown or a safety at any point in overtime ends the game immediately. In the NFL regular season, that is true on the first drive or any later drive. In the playoffs, a defensive score on the first possession ends the game as well.
In college, if the defense gains possession and returns the ball for a touchdown during a normal overtime drive from the 25, the game ends. During the two-point shootout (from the third overtime onward), the defense can also score two points by returning a turnover to the opposite end zone because the play is treated like a two-point try.
Scoring, conversions, and kicks
Extra points and two-point tries in college
In the first overtime, college teams can kick the extra point after a touchdown or go for two, just like in regulation. From the second overtime on, they must go for two. This rule adds pressure and often speeds up the result. It also changes the play-calling mix because the offense must carry a set of favorite two-point plays even when the field is tight and the defense is ready.
Field goals and special teams in the NFL
Field goals are a big part of NFL overtime strategy, especially in the regular season. A field goal on the opening possession does not end the game, but it puts serious pressure on the opponent. A later field goal—after both teams have possessed—can win it immediately in sudden death. Punting, field position, and clock usage all matter because the overtime period is timed.
No kickoffs in college overtime
There are no kickoffs in college overtime and no return yards to gain advantage. Teams start at the same spot—the 25-yard line—and must find the end zone or set up a makeable field goal. This shifts emphasis from special teams to red-zone efficiency and short-field defense.
Timeouts, reviews, and challenges
NFL overtime timeouts and replay
In the NFL regular season, each team gets two timeouts in overtime. In the playoffs, additional timeouts are available across multiple overtime periods, and the structure is treated more like extended quarters. Replay reviews in overtime are initiated by the replay official; coaches do not have challenge flags in overtime. The play clock and timing rules mirror those in regulation.
College overtime timeouts and replay
In college, each team gets one timeout per overtime period. Timeouts do not carry over to the next overtime. Replay operates under NCAA rules and can be used to correct scoring plays, turnovers, and other reviewable situations. There is no game clock, but the play clock (such as 40 seconds between plays) is still in effect, so offenses must operate with their normal cadence.
Ties and how games end
NFL regular season ties
In the NFL regular season, if neither team is ahead after the 10-minute overtime period, the game ends in a tie. This is rare compared to other sports, but it happens a few times each season. Ties can affect playoff seeding but count as half wins and half losses in standings.
No ties in college
College football does not allow ties. Overtimes continue under the alternating-possession format, and then the two-point shootout, until someone wins. The two-point-only rounds were introduced to avoid marathon games with dozens of extra plays.
Strategy differences you will notice
What coaches want from the coin toss
In the NFL regular season, most coaches who win the coin toss choose to receive because a touchdown ends the game. If they fail to score, they can still punt, flip field position, and play clock control. In the NFL playoffs, the decision is closer. Some may still prefer the ball first to set the tone, while others may consider deferring to understand the scoreboard pressure after both teams are guaranteed a possession.
In college, the standard is to play defense first. Knowing whether you need three points, seven points, or a two-point conversion at the end of your drive helps you plan your entire series. It also influences whether to kick a field goal on fourth down or stay aggressive.
Play calling and risk tolerance
College overtime encourages more fourth-down aggression, especially once the second and third overtime arrive. The field is short, and the cost of giving up a field goal vs. a touchdown can push coaches to take chances. In the NFL regular season, coaches may be more conservative on the first possession if a field goal at least guarantees the opponent must respond. In sudden death, however, a single mistake can end the game immediately, so risk management is crucial.
Kicker and fourth-down decisions
In the NFL, kickers can be heroes in overtime. A long field goal can end the game once sudden death starts. On the first drive of regular-season overtime, a field goal is useful but not decisive. That subtlety shapes decisions: do you try a long kick and give up field position if you miss, or do you punt and trust your defense?
In college, most kick attempts are shorter because the drive starts at the 25. That makes a reliable kicker a strong asset, but the mandatory two-point rule from the second overtime limits how often a kick can decide the outcome. Teams must be ready to execute two-point plays and defend them repeatedly.
Defensive approach
NFL defenses in overtime balance aggression with caution because one explosive play can end it. In regular-season overtime, preventing a touchdown on the first drive is priority one; forcing a field goal keeps the game alive and gives your offense a fair shot. In college, defenses tighten in the red zone. With the ball already at the 25, red-zone packages and short-yardage discipline matter more than preventing explosive plays over a long field.
Examples and walk-throughs
Example 1: NFL regular-season overtime scenario
Imagine the score is tied at the end of regulation. The visiting team calls the coin toss and wins; they choose to receive. They start the overtime with a drive that reaches the opponent’s 30-yard line. On fourth-and-3, they choose to try a 48-yard field goal. The kick is good. The score is now 23–20.
Because it is the first possession and only a field goal was scored, the other team gets a possession. They start on their own 25 after the kickoff. Their drive stalls at midfield, and they face fourth-and-10. They go for it and fail. The first team gets the ball back near midfield with several minutes remaining on the 10-minute clock. Now it is sudden death: the next score wins. They move into range and kick a 50-yard field goal. Game over, 26–20.
If that opening drive had ended with a touchdown instead of a field goal, the game would have ended right there, 27–20, without the other team ever possessing the ball.
Example 2: NFL playoff overtime scenario
It is a playoff game, tied at 28–28. The home team wins the coin toss and chooses to receive. They drive 75 yards and score a touchdown. In the playoffs, the game does not end here. The visiting team now gets a guaranteed possession. They drive and also score a touchdown, tying it at 35–35. After the second team’s extra point, overtime becomes sudden death: the next score of any kind wins.
The home team receives the next kickoff and goes three-and-out. They punt, and the visitors start near midfield. One deep pass later, they are in field-goal range and kick a 42-yarder. Game over. The guarantee of one possession each made the start fair, but once both offenses had their turn, the game returned to the classic next-score-wins finish.
Example 3: College overtime through three periods
It is 24–24 at the end of regulation. Team A wins the coin toss and chooses to play defense first. Team B starts at Team A’s 25-yard line and kicks a field goal after stalling. Team A now gets the ball at the B25 and scores a touchdown. They choose to kick the extra point in the first overtime and lead 31–27. Team A wins because both teams had a possession and Team A scored more.
If Team B had also scored a touchdown, the game would move to a second overtime. Now Team A must try a two-point conversion after any touchdown. Suppose Team A scores and fails the two-point try, making it 37–30. Team B scores a touchdown and now must go for two as well. If Team B converts, they win 38–37. If they fail, the game moves to a third overtime tied at 37–37.
In the third overtime, there are no full drives from the 25. Team A gets one two-point play from the three-yard line and fails. Team B then runs its two-point play and succeeds. Game over. This two-point-only stage can be dramatic, and it keeps the number of total snaps lower than playing endless full possessions.
Player safety and pace of play
Why the NCAA added the shootout format
In the past, college games could stretch into many overtime periods, with teams trading touchdowns and field goals from the 25 over and over. To limit the total number of plays and reduce injury risk, the NCAA updated overtime so that mandatory two-point tries begin in the second overtime and two-point shootouts start in the third. This structure keeps drama high while capping the physical toll on players.
The NFL approach to ties and workload
The NFL keeps a timed overtime in the regular season and allows ties to prevent games from dragging on too long. This balances competitive results with player safety and the season’s physical demands. In the playoffs, where a winner must emerge, overtime periods are longer, and play continues—but the recent rule change guaranteeing both teams a possession aims to balance fairness with the need for a clear result.
Common myths and quick clarifications
Myth: NFL overtime is always sudden death
Not exactly. In the regular season, the first drive is not sudden death unless it ends with a touchdown or a defensive score. A field goal on the opening drive gives the other team a chance to respond. After both teams have had a possession (or if the first possession ended in a touchdown), it becomes sudden death. In the playoffs, both teams get a possession before sudden death begins.
Myth: College overtime is just like the NFL but shorter
No. College overtime uses alternating possessions from the 25-yard line, with no kickoffs and no game clock. It is a fundamentally different setup that emphasizes short-field offense and defense and introduces mandatory two-point attempts.
Myth: The defense cannot score in overtime
They can in both formats. In the NFL, a defensive touchdown or safety ends the game on the spot. In college, a defensive touchdown during a standard overtime possession ends the game. During two-point tries, the defense can also return a turnover for two points.
Historical notes and recent changes
NFL postseason possession rule change
After some high-profile playoff games where the coin-toss winner scored a first-drive touchdown and the other team never touched the ball, the NFL adjusted postseason overtime. Now, both teams are guaranteed one possession in the playoffs before sudden death. This change balances fairness without altering regular-season timing or tie rules.
NCAA two-point rules update
The NCAA tweaked college overtime in 2021 to move to the two-point shootout starting in the third overtime and to require two-point tries after touchdowns from the second overtime on. The goal was to reduce the total number of snaps and speed up the endgame while preserving fairness and excitement.
Which format is more exciting? A balanced view
Drama and fairness
College overtime often feels like a penalty shootout in soccer: two teams trading must-have plays from a short distance. The tension is intense, and every play is high leverage. The NFL, especially in the playoffs, mixes fairness (both teams get a possession) with the traditional feel of normal football drives and special teams. Which is “better” depends on whether you prefer structured equality of chances (college) or the full field and timed tactics (NFL).
Purity versus special situations
The NFL keeps the full breadth of the sport in play—kickoffs, punts, long fields, and clock management. College focuses the action into the red zone and removes clock and kickoff complexity. Neither is wrong. They are different answers to the same question: what is the best way to break a tie?
Tips for watching overtime as a new fan
What to track on the broadcast
In the NFL, note who wins the coin toss and whether they receive. Remember: a first-drive touchdown in the regular season ends the game; in the playoffs, it does not. Watch the game clock, because it can expire to end a regular-season overtime in a tie. Keep an eye on timeouts, field position, and whether a field goal would end the game based on where you are in the sequence.
In college, note which team goes on offense first and what they score. Every possession starts at the 25, so pay attention to red-zone efficiency. From the second overtime, expect two-point tries after touchdowns. From the third, prepare for alternating two-point plays; broadcast graphics will usually make this clear.
How to predict choices
In the NFL regular season, if the first offense reaches long field-goal range on fourth-and-short, they might choose to kick early to take the lead. If they are out of range, they may punt and play field position. In sudden death, a single field goal wins, so conservative choices become more attractive. In the playoffs, play-calling can be bolder because the other team is guaranteed a possession.
In college, coaches often go for it on fourth down inside the 25 because the starting field position makes a field goal relatively easy anyway. In later overtimes, they keep a short list of favorite two-point plays and may repeat looks with small variations. On defense, expect tight coverage and heavy emphasis on red-zone run fits.
A side-by-side sense check: what to remember
Core NFL takeaways
Regular season: one 10-minute period, a first-drive touchdown can end it, ties are possible. Postseason: both teams get a possession, 15-minute periods, sudden death after both have had the ball, and play continues until someone wins.
Core college takeaways
Alternating possessions from the 25 with no game clock. After the first overtime, two-point conversions are mandatory after touchdowns. From the third overtime, it is a two-point-only shootout. No kickoffs, no ties, and heavy red-zone tactics.
Conclusion
The NFL and college football take very different paths to decide overtime games. The NFL keeps a timed, full-field version of football, with kickoffs, punts, and clock strategy—ending in ties during the regular season but guaranteeing both teams a possession in the playoffs. College football turns overtime into a series of equal-position chances from the 25-yard line and then into a two-point shootout to speed up the finish. These choices reflect each level’s priorities: the NFL balances fairness with season-long player workload, while the NCAA emphasizes equal scoring chances and controlled play counts.
If you remember just a few things, make them these: NFL regular-season overtime can end on a first-drive touchdown and can end in a tie, while NFL playoff overtime gives both teams a possession and continues until someone wins. College overtime starts each team at the opponent’s 25, requires two-point tries after touchdowns from the second overtime, and becomes a two-point-only contest from the third. With those basics, you will be ready to enjoy the drama on Saturdays and Sundays—and to explain it to anyone sitting next to you.
