FAQs

How are parlay odds calculated?

Multiply the decimal odds of every leg together. All legs must win for the parlay to pay out.

Why do sportsbooks like parlays?

Because the combined implied probability compounds down fast — a parlay of several legs at seemingly reasonable individual odds has a much lower true chance of winning than it might feel like, while the payout grows the house edge across every leg.
