How the builder works
Pick a sport, open an upcoming game, and add the selections you want. The builder prices your exact slip live against every sportsbook we track and shows you two clearly separated numbers.
The two numbers
Best Book for This Parlay is the placeable number. It prices your whole slip at each sportsbook that offers every leg at the same selection and the same line, ranks them, and shows the one that pays the most. That is a real ticket you can place at one book.
Best Possible, Separate Bets is the ceiling. It takes each leg at its own best book and multiplies them. It is the most a perfect shopper could get, but it is several separate single bets, not one parlay ticket, and cannot be placed as a single bet.
Treat every figure as an estimate, not a final price. Odds move constantly, and you should confirm the current price and payout at the sportsbook before placing any bet. Same-game parlays are shown as an estimate only, because sportsbooks price the legs as correlated and the real price will differ.
Player props in your parlay
Player props go into a parlay the same way game lines do. Open a game, expand its player props, and add an over or under. The builder treats a prop like any other leg and only counts a sportsbook as offering it when that book posts the exact same player, market, and line, so your slip is never priced against a different number. Props from the same game are shown as an estimate only, the same as a same-game parlay, because the book prices those legs as correlated. For the full prop board, open our NBA player props page, or the player props page for any sport that lists them.
