That's why we keep you away from situations you haven't thought of.
Let’s say you like top scorers and H. Kane is your man for goals. If you bet on H. Kane to have at least one shot on target and he was substituted before the start of the second half, then you're protected from bad luck, as your stake will be refunded!
If H. Kane was subbed off before the start of the second half but managed to have a shot on target, you can pop the champagne because your bet is validated as a win!
However, your bet is lost if you placed a bet on H. Kane to score the first goal of the match, he was substituted before the start of the second half, and a teammate or an opponent managed to score the first goal.
