Parlay meaning: what does parlay mean in betting?
A parlay is the American term for a single bet that links two or more selections together, rolling the winnings from each onto the next, and that pays only if every selection wins.
A parlay trades probability for payout. Each pick in it is a leg. Win the first and the whole return rides on the second, then the third. Miss one and the ticket is dead.
It’s the US and Canadian word. In the UK and Ireland the same bet is an accumulator, or acca. Elsewhere you’ll see “multi”, “multiple” or “combo”. No difference in how it works.
Example
Three NFL spreads, each at the standard −110.
- Convert each leg to decimal: −110 = 1.91 (exactly 1.909, which bookmakers round to 1.91).
- Multiply: 1.91 × 1.91 × 1.91 = 6.97.
- A $100 stake returns about $697, so roughly $597 profit. In American odds, that’s about +597.
Now the catch. If each leg is a true coin flip, three in a row come in one time in eight. Fair odds would be 8.00, or +700. You’re being paid 6.97. The gap is the book’s juice, multiplied across three legs.
| Legs at −110 | Parlay pays | Fair price for coin flips |
|---|---|---|
| 2 | 3.65 | 4.00 |
| 3 | 6.97 | 8.00 |
| 4 | 13.31 | 16.00 |
The gap widens with every leg you add.
Watch out
- Pushes and voids. If one leg ties, most books drop that leg and re-price the rest. A three-leg parlay becomes a two-leg one. Some books settle differently, so check.
- Fixed payout tables. A few sportsbooks pay parlays from a set chart (say, 6/1 for three teams) instead of true multiplied odds. That’s usually worse.
- Correlated legs from the same game belong in a same game parlay, priced separately.
I enjoy a small parlay. I don’t pretend it’s a strategy. Read my full guide to parlays, or test your own ticket in the parlay calculator.
