An overtime field goal can decide your total. A tie can hand back your moneyline stake. A receiver who plays one snap and limps off can still lose you an over.
None of that is in the odds. It is in the house rules, the fine print every sportsbook publishes on how each bet is graded. Football has fewer strange endings than hockey, which has the shootout, but overtime, ties and player participation still decide real bets every week. Here is how the standard rules at major U.S. sportsbooks work, and where books differ.
1. Overtime counts for full-game bets
Unless the market says otherwise, moneylines, spreads and totals are graded on the final score including overtime.
Bills and Dolphins are tied 20–20 at the end of regulation. The total is 43.5, and the under looks safe at 40 points. What happens next decides the bet:
| Overtime result | Final | Under 43.5 |
|---|---|---|
| No score (regular season) | 20–20 | Wins |
| Field goal | 23–20 | Wins |
| Touchdown | 26–20 or more | Loses |
The spread works the same way. A 3-point favorite that wins 23–20 on an overtime field goal is a push at −3, and the underdog at +3.5 wins.
2. When an NFL game ends in a tie
Regular-season games get one 10-minute overtime period. If the score is still level after it, the game ends in a tie. That is rare, but it happens. Playoff games keep going until someone wins, so they cannot end tied.
How a tie is graded depends on the bet:
- Two-way moneyline (the standard one, with just two teams to pick): major U.S. books grade a tie as a push and return your stake.
- Three-way moneyline (the tie is offered as its own outcome): the tie is the result, so bets on either team lose.
- Spread: graded as usual. An underdog at +3 covers a tie. A pick’em spread (0) pushes.
- Total: graded on the tied final score.
A three-way moneyline always pays more on each team than the standard moneyline, because it loses when the game is tied. That is not a better price on the same bet. It is a different bet with an extra way to lose.
The same trap shows up in hockey, where a “60-minute” line is a different bet from the full-game moneyline. Our NHL rules guide shows how mixing the two can turn an apparent sure thing into two losing tickets.
In a parlay, a pushed leg is usually dropped and the parlay pays at the odds of the remaining legs. Books do not all handle it the same way, so check yours if you parlay NFL moneylines.
3. Half and quarter bets: read the label
First-half and first-quarter bets end before overtime, so it never comes up. Later periods are where books disagree:
- Second half: many books include overtime in second-half bets, but not all.
- Fourth quarter: often graded on the fourth quarter alone, without overtime.
If the market name does not say, the house rules do. This is one of the most common places where two books’ “same” bet is not the same bet.
4. Player props: overtime counts, and one snap is enough
Standard player props count statistics from the whole game, including overtime. A 30-yard catch in overtime counts toward a receiver’s yards and can be what clears the over.
Participation is the bigger issue:
- The player does not play (inactive, or never takes the field): the bet is void and your stake is returned, whether you bet the over or the under.
- The player plays and gets hurt: at most major books one snap counts as playing. After that, the bet stands and is graded on whatever he finished with.
So suppose you bet a running back over 64.5 rushing yards. He carries twice for 6 yards and leaves in the first quarter. The bet stands and loses. Someone who bet the under on the same player wins. The wording differs from book to book, so if you bet props often, find the participation rule at yours.
5. Postponed, moved or suspended games
If a game is postponed and not played within the book’s deadline, bets are void. Each book sets its own deadline, and books also differ on whether bets stand when a game moves to a different venue. A game paused for weather and finished the same day is graded on its final result like any other.
Why this matters when you compare prices
Comparing prices only works when the bets are the same. A three-way price next to a two-way moneyline, or a fourth-quarter line that excludes overtime next to one that includes it, will look like a bargain that is not there. The same goes for removing a book’s margin to estimate a fair probability: you can only devig two sides that are graded the same way.
Before you shop a line, check that each book is selling the same bet. Then the price comparison means something.
A quick checklist before you bet
- Does it include overtime? Full-game bets and player props: yes. Second-half and fourth-quarter bets: check.
- Two-way or three-way moneyline? Two-way pushes on a tie. Three-way loses on a tie.
- What if the player is inactive or leaves early? Inactive: void. One snap: usually stands.
- How are pushed parlay legs handled? Usually dropped, but check.
- What is the postponement deadline? It is set by each book.
- Which state are you in? House rules can differ by jurisdiction.

Frequently asked questions
Does overtime count in NFL over/under bets?
Yes. Full-game totals, spreads and moneylines are graded on the final score including overtime, unless the market is labeled regulation-only.
What happens to an NFL moneyline bet if the game ends in a tie?
On a standard two-way moneyline, major U.S. sportsbooks grade a tie as a push and return your stake. On a three-way moneyline, the tie is its own outcome, so bets on either team lose.
Do NFL player props include overtime?
Yes. Standard player props count statistics from the whole game, including overtime.
What happens to an NFL player prop if the player does not play?
If the player is inactive or never takes the field, the bet is void and the stake is returned. At most major books one snap counts as playing, and the bet then stands even if the player leaves injured.
Do second-half and fourth-quarter bets include overtime?
It depends on the book. Many count overtime in second-half bets, while fourth-quarter bets often exclude it. Check the market name and your book’s house rules.
This guide describes common rules at major U.S. sportsbooks as of October 2026. Rules change and differ by book and state. Your sportsbook’s published house rules decide how your bet is graded.
