Oddcraft

Whether you've been betting for years or you just opened your first app, Oddcraft shows you the real price behind every bet. What the book is keeping, where fair actually sits, and which book has the better number.

Your sportsbook has a number it will never show you.

On a five-leg parlay at -110 a leg, it keeps 20.8% of every dollar wagered. The whole ladder:

1 leg ····· 4.5%
2 legs ····· 8.9%
3 legs ····· 13.0%
4 legs ····· 17.0%
5 legs ····· 20.8%

That's more than one dollar in every five, gone before you lose a single bet you shouldn't have.

We can't make the vig disappear. Nobody can.
We make sure you never pay it blind, and never pay it twice.

WE DON'T POST A RECORD. ON PURPOSE.

Anyone can screenshot a win. Nobody screenshots the method.

Every number in here you can check yourself, straight off the odds — implied probability, hold, break-even, closing line value. If a room shows you a number and won't show you how it got there, that's the tell.
