The 3 American football markets OddScore tracks
OddScore tracks three markets on American football: the winner of the game, the spread (handicap) and the over/under on total points. Odds are refreshed every 15 minutes. Each match gets a 0-100 signal and, about 30 minutes before kickoff, an AI reading.
The method is the same as on other sports: compare odds across several sportsbooks, convert them into real probabilities, then read the gaps. The detail is on the How it works page and the vocabulary in the glossary.
The winner market: 2 outcomes in practice
The OddScore winner market has 2 outcomes: home team or away team. In the playoffs, the game is played until there is a winner.
In the regular season, overtime lasts 10 minutes at most. Since the 2025 season, each team gets at least one possession in overtime. If the score is still level, the game is recorded as a tie. It is possible but rare, and how a bet is settled in that case depends on the sportsbook rules: read them before betting.
The spread: key numbers 3 and 7
The spread is the most followed market in American football. One team is given a points handicap to balance the matchup, for example -3.5 for the favorite. How a handicap works in general is explained on the handicap betting page.
What is specific to American football is the key numbers. A field goal is worth 3 points and a converted touchdown 7, so final margins of 3 and 7 points come up more often than others. Three consequences:
- A -3 line can be refunded if the favorite wins by exactly 3. A -3.5 line cannot.
- Moving from -3 to -3.5, or from -6.5 to -7, shifts more probability than a half point elsewhere on the scale.
- A half-point move onto a key number reads differently from a half-point move around 5.5.
This does not tell you who will win. It helps you understand what the market is really worth when the line moves.
Over/under points
OddScore also tracks the over/under on the total points of the game, on a half-point line (for example 44.5). How this market works in general is explained on the dedicated Over/Under page.
This market reacts fast to weather (wind, rain, cold), the state of the offense and a quarterback injury. The total line and the spread often move together.
Reading a line movement during game week
An American football team plays once a week, and the market opens several days before. Three sources of information move the lines:
- The injury report: teams publish a report during the week. Quarterback status weighs the most.
- The weather: it mostly affects the total, less the winner.
- The schedule: a game after a short week or a long trip.
OddScore checks whether a move is confirmed by several sportsbooks at once and when it appears. A move seen on Monday does not read like a move just before kickoff. The three markets are compared to see whether they tell the same story or contradict each other.
Regular season, playoffs and Super Bowl
- Regular season: 17 games per team over 18 weeks (one bye week per team). In 2026, it runs from September 9, 2026 to January 10, 2027.
- Playoffs: they start with Wild Card Weekend on January 16, 2027, then the following rounds up to the conference championship games.
- Super Bowl LXI: February 14, 2027 at SoFi Stadium (Inglewood, California).
Between February and August there are no NFL games: OddScore observes a seasonal break and analyses resume with the season.
NFL and NCAAF
OddScore tracks the NFL and NCAAF (college football). Both competitions use the same markets, but rules and calendars differ. Check the rules of a game before reading it with NFL benchmarks, especially for overtime.
OddScore is not an American football tipster site
Like on other sports, OddScore doesn't hand you a bet to follow blindly. The app offers a reading of the market: odds movements, real probabilities, sportsbook signals, without ever guaranteeing a result.
Remember: in American football as in other sports, OddScore doesn't give you a bet to copy. OddScore helps you understand what the market is saying.

UnderstandFrequently asked questions
Which American football markets does OddScore analyze?
Three markets: the match winner (2 outcomes), the spread (handicap) and over/under on total points. OddScore reads odds movements and produces a 0-100 signal on these markets.
Which American football competitions are tracked?
The NFL and NCAAF (US college football). OddScore does not announce other American football competitions for now.
What are the key numbers 3 and 7 in American football?
They are the most frequent final margins, because a field goal is worth 3 points and a converted touchdown 7 points. A spread sitting on 3 or 7 is therefore more sensitive than other lines.
Why do half-point lines matter in American football?
A -3 line can be refunded if the team wins by exactly 3 points. A -3.5 line can never be refunded. Moving from -3 to -3.5 therefore changes the real probability of the bet.
Can an American football game end in a tie?
Not in the playoffs, where overtime continues until there is a winner. In the regular season, overtime is 10 minutes and the game can stay tied if the score is level at the end. This is rare. How a tie is settled depends on the sportsbook rules.
How long is the NFL season?
The 2026 regular season has 17 games per team over 18 weeks, from September 9, 2026 to January 10, 2027. The playoffs follow, then Super Bowl LXI on February 14, 2027. OddScore observes a break between February and August.
How do I read a line movement during an American football game week?
First check whether the move comes from public information: injury report, quarterback status or weather. Then check whether several sportsbooks move the same way. A move shared by the whole market carries more weight than an isolated one.
Does OddScore give American football tips?
No. OddScore is not a tipster site. The application helps you read odds movements and market signals on the winner, the spread and over/under points.
