Moneylines, Spreads, and Totals: The Three Core Bet Types
In short: Every major sport offers three core market types. Moneylines bet on who wins. Point spreads bet on whether a team wins by enough points to “cover” a handicap. Totals bet on the combined score of both teams. These three markets account for the majority of sports betting volume, and each one behaves differently.
Most other bet types — props, parlays, futures, live betting — are variations on these three core ideas. Get fluent with the basics and the rest is easier.
Moneyline (Who Wins?)
The simplest bet: pick the winner. No point spread, no complications.
On a moneyline bet, the favorite has negative odds and the underdog has positive odds. The bigger the gap, the more lopsided the matchup.
Example:
- Celtics -200 (favorite): risk $200 to win $100
- Lakers +170 (underdog): risk $100 to win $170
In most US sports, exactly one team must win — there are no draws. NBA games go to overtime; MLB plays extra innings; NHL goes to overtime and shootout.
Soccer is the major exception. Most international soccer matches use a “1X2” market with three outcomes: home win, draw, or away win. This changes the math significantly. A two-leg arbitrage on a three-outcome market doesn’t work — a draw loses both bets.
NFL is a nuanced case. Regular-season games can end in a tie after overtime. Some books offer a three-way moneyline for regulation only (home/away/tie) alongside the standard two-way moneyline that includes overtime. Always check whether you’re betting “regulation only” or “including overtime” — mixing these across different books will break your math.
Point Spread (Who Wins After the Handicap?)
The point spread levels the playing field by giving the underdog a head start. Instead of picking the winner outright, you’re picking who wins after a handicap is applied.
Example:
- Celtics -5.5 (-110): must win by 6 or more points
- Lakers +5.5 (-110): can lose by up to 5 points (or win outright)
The half-point in the spread (the “.5”) exists to prevent pushes — ties against the spread where neither side wins. If the spread were exactly -5 and the Celtics won by 5, both sides would push and stakes would be returned.
When the spread is a whole number and the result lands on it exactly, that’s a push. All bets refunded, no action.
Why Spreads Exist
Point spreads exist because moneylines on lopsided games create unattractive prices. A 14-point favorite might be -800 on the moneyline (risk $800 to win $100, almost no upside) while the underdog is +600 (huge potential payout, but unlikely to win).
The spread converts that into a roughly even-money bet. Celtics -7.5 (-110) vs Lakers +7.5 (-110) gives both sides similar odds and forces the question: not “who will win?” but “who will win by how much?”
This makes spreads the most popular market in football and basketball. They keep blowout games interesting.
Key Numbers in Football
In football, the most common margins of victory are 3 (a field goal) and 7 (a touchdown). The next most common are 6, 10, and 14. These key numbers carry outsized importance in spread betting.
Lines that cross key numbers — moving from -2.5 to -3.5, for example — change win probability much more than lines that don’t. Moving from -2.5 to -3.5 takes you from “wins if favored team wins by 3+” to “wins if favored team wins by 4+.” Since 3 is one of the most common margins, that’s a much bigger swing than moving from -8.5 to -9.5.
This matters for middles, where the goal is to find spread gaps spanning key numbers — those windows have disproportionately high hit rates.
Totals / Over-Under (How Many Points?)
Totals bets are about the combined score of both teams, not who wins. The book sets a number, and you pick whether the actual combined score will be over or under it.
Example:
- Over 215.5 (-110): combined score of 216 or higher
- Under 215.5 (-110): combined score of 215 or lower
Like spreads, totals lines often use half-points to avoid pushes. When they don’t, a result landing exactly on the number pushes both sides.
Why Totals Are Interesting for Edge Finders
Totals are usually less closely watched by the betting public than spreads or moneylines. The casual fan cares more about who wins than about the combined score. This means:
- Lines move slower when news affects scoring (weather, lineup changes, pace)
- Sharper books and retail books often diverge more on totals than on sides
- More mispricing persists longer
This is why totals are a particularly rich area for finding arbitrage and +EV opportunities, especially in lower-profile games.
A Real Example Across All Three Markets
Here’s how a real game looked across all three markets on April 23, 2026 — Boston Celtics at Indiana Pacers:
| Market | Favorite | Underdog |
|---|---|---|
| Moneyline | Celtics -180 | Pacers +150 |
| Spread (-4.5) | Celtics -110 | Pacers -110 |
| Total (218.5) | Over -110 | Under -110 |
If you wanted to bet the Celtics, you had three options:
- Moneyline: Celtics win → bet wins. Risk $180 to win $100.
- Spread: Celtics win by 5+ → bet wins. Risk $110 to win $100.
- Total: Has nothing to do with who wins; just whether combined score exceeds 218.5.
The Celtics won 112-104, a margin of 8. The combined score was 216.
- Moneyline: Celtics win → wins
- Spread: Celtics by 8 (more than 4.5) → wins
- Total: 216 (under 218.5) → Under wins
Three different markets, three different calculations from the same game.
Which Market Should You Bet?
Different markets favor different strategies.
Moneylines are the simplest and most popular. They’re best for bettors who care about who wins more than how convincingly. On lopsided games, moneylines are also where heavy underdog value can appear (+500 dogs occasionally hit, and one win can pay for several losses).
Spreads are the workhorses of football and basketball. They produce roughly even-money bets on every game and create the conditions for middles and key-number value.
Totals are often the best market for edge-finding because they’re less efficient than sides. They also avoid the “I picked the wrong team” emotional element — you’re not rooting for one side, just for a particular scoring environment.
For systematic strategies like arbitrage and +EV, the answer is “all of the above.” A scanner watches every market, and the best edges show up wherever the books happen to disagree most.
Frequently Asked Questions
What does -7.5 mean?
It means the favored team has been handicapped by 7.5 points. To “cover” the spread, they need to win by 8 or more. The half-point ensures there’s no push — either they win by 8+ (cover) or they don’t (don’t cover).
What’s the difference between a moneyline and a spread?
A moneyline bet wins if your team wins outright, regardless of margin. A spread bet wins only if your team wins by more than the spread (or, if you took the underdog, loses by less than the spread or wins outright).
Why are most spreads at -110?
Because -110 on both sides is the standard pricing structure that gives the book a roughly 4.5% margin (the vig). This is the default for spreads and totals in most markets. Some sharp books offer reduced juice (-105/-105) to attract sharper action.
What’s a “push”?
A push happens when the result lands exactly on the line — a Celtics -5 spread where the Celtics win by exactly 5, or a 215 total where the combined score is exactly 215. Both sides have their stakes refunded, no winner. Half-point lines (-5.5, 215.5) prevent pushes by making the line uncrossable in either direction.
Can I bet on draws?
In sports where draws are possible (soccer, regulation NFL), some books offer them as a separate three-way moneyline option. The “draw” line typically has high positive odds because draws are less common than wins by either side.
