A parlay is a single bet that combines multiple picks — and every single pick must win for the parlay to pay out.
Parlays are the most exciting bet type for beginners and one of the most profitable bet types for sportsbooks. Understanding exactly how they work helps you use them smartly — or avoid them when they don't make sense.
How a Parlay Works
Let's say you pick three NFL games on a Sunday:
- Chiefs -3 (-110)
- Eagles moneyline (-120)
- Cowboys/Giants Over 44.5 (-110)
Instead of betting each separately, you combine them into a parlay. Your stake rides on all three winning. If all three hit, your payout is dramatically larger than three separate bets.
A standard 3-team parlay at -110 odds across the board pays approximately +595 — a $100 bet returns $695. The tradeoff: if any single leg loses, the entire parlay loses.
Parlay Odds Are Multiplied
Each leg of a parlay multiplies against the others. The more legs you add, the higher the potential payout and the lower the probability of winning:
| Legs | Approximate Payout (all -110) | |———|———————————————-| | 2 | +260 | | 3 | +595 | | 4 | +1,228 | | 5 | +2,435 |
These numbers look appealing. But remember: each added leg reduces your win probability significantly.
When Parlays Make Sense
Parlays make sense when:
- You want to turn a small stake into a meaningful payout
- You're using them as a small portion of your betting activity (not your entire strategy)
- All legs offer genuine value, not just convenient picks
Parlays make less sense when:
- You're relying on them as your primary strategy
- You're adding legs just to increase the payout
- Multiple legs are on the same game (correlated parlays — some books don't allow these)
Parlay vs. Individual Bets: The Math
If you bet three -110 games individually at $33 each, your theoretical expected value is similar to a parlay — but your variance is much lower. You could split wins and losses; in a parlay, it's all or nothing.
Most disciplined bettors limit parlays to a small fraction of their activity and focus on single game bets for consistency.
