How it works
- The refund is worth its cash value, or the bonus amount × your conversion rate.
- It's only paid when the trigger happens, so its value is that chance × the refund.
- Lay at the exchange to spread the refund's value across both results.
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.
