How it works

A parlay rolls the full return of each leg into the next, so the decimal odds multiply. Payouts grow quickly, but so does the margin you pay: the book's vig compounds on every leg.

The implied probability shows how often the parlay needs to hit just to break even at this price.

parlay decimal = decimal₁ × decimal₂ × … × decimalₙ

payout = stake × parlay decimal

implied probability = 1 / parlay decimal
