How Parlays Work
A parlay combines two or more individual bets into a single wager. All legs must win for the parlay to pay out. The combined odds are calculated by multiplying the decimal odds of each leg together.
While parlays offer larger payouts, the implied probability of winning decreases with each added leg. This calculator helps you see the true probability so you can make more informed decisions.
TrueVig's +EV engine can help you find positive expected value parlays by identifying legs where sportsbook odds are mispriced compared to true probabilities.
