What Is a Parlay (and Are They Worth It)?

A parlay (or accumulator) combines multiple selections into a single bet. A three-team parlay only pays if all three win; one loss sinks the whole ticket. In return, the payout is far bigger than betting each game on its own.

How parlays work

To price a parlay, convert each leg to decimal odds, multiply them together, and multiply by your stake. Three -110 legs combine to about 6-to-1, so a $100 ticket returns roughly $700. Our parlay calculator does the math for any number of legs.

Why the payouts look so big

Because hitting every leg is hard. Three coin-flip legs only come in about one time in seven. The payout is large precisely because the probability is small — and the vig on each leg multiplies through the whole ticket, so the book's built-in edge grows with every team you add.

When does a parlay make sense?

When each leg is a bet you'd make on its own — one with a real edge. Stacking positive-EV legs can be fine; stacking coin flips for a lottery payout is how the house wins. Parlays don't turn bad bets into good ones; they multiply whatever edge (or disadvantage) the legs already carry.
