    Cross-book bonus bet converter

    Turn a bonus bet into cash by backing the other side at another bookie.

    Your bonus bet

    Back each other outcome with cash at a different bookmaker. Bookmakers are labels only.

    With a stake-not-returned bonus, higher odds on the bonus leg usually convert better. Pick a long price and cover it with the shortest odds you can find elsewhere.

    Cash to put on

    Stakes are sized so you finish on the same profit whichever outcome lands.

    Fill in the numbers to see the result.

    How it works

    • Put the bonus bet on one outcome at one bookmaker.
    • Back every other outcome with cash at other bookmakers, sized so every result pays the same.
    • Conversion rate = locked-in profit ÷ bonus bet.

    Betting involves risk. Bookmakers can restrict or close accounts and void bets, automation can fail, prices move, and a positive expected value (+EV) bet can still lose. Promotions carry each bookmaker's own terms. There is no guarantee of profit. See responsible gambling for limits and support.
