How parlay payouts work
Each leg's odds multiply together. Two -110 bets pay about 2.6 to 1; three pay about 6 to 1; four pay about 12 to 1. One missed leg loses the entire ticket. The soaring payout is real, but so is the falling probability, and the book's margin is baked into every leg you add.
A worked example
A $20 three-team parlay of -110 favorites pays roughly $119 profit if all three win. Miss any one and you lose the $20. The fair payout without the vig would be higher than $119, and that hidden gap is the book's edge, multiplied three times over.
Using parlays wisely
Parlays are worth it only when each leg is a bet you would make on its own at a good number. If you want the upside with less risk, a round robin spreads the picks so one miss does not bust everything. For steady results, straight bets at the best price beat parlays over time.
Frequently asked questions
How many legs can a parlay have?
Most books allow up to a dozen or more. The more legs, the bigger the payout and the lower the chance of hitting every one.
Does one loss ruin a parlay?
Yes. Every leg must win. A single loss voids the whole parlay, unless a leg pushes, which usually drops that leg and reprices the ticket.
