Frequently Asked Questions
What is a parlay bet?
A parlay combines multiple individual bets (legs) into one bet. All legs must win for the parlay to pay out. The odds multiply together, creating much higher potential payouts but lower probability. A 3-leg parlay at -110 each pays about +596.
How is parlay payout calculated?
Convert each leg to decimal odds, multiply them together, then multiply by your bet amount. Example: Leg 1 (-110 = 1.909), Leg 2 (+150 = 2.500). Combined: 1.909 x 2.500 = 4.773. A $100 bet pays $477.30.
What is a round robin bet?
A round robin creates all possible parlay combinations of a certain size from your selections. With 3 picks and 2-leg parlays, you get 3 separate parlays. This provides insurance because you can still profit even if one pick loses.
