All soccer bets are settled on the result at the end of 90 minutes including stoppage time, unless specifically stated otherwise in the market description (Such as ‘To Qualify’, ‘Lift the Trophy’, or ‘To Win the Tie’ which all include overtime results).
This means that for most bet types including anytime goalscorers, corners, free kicks, passes, goal kicks or bookings that occur in extra time will not count towards the result of your bet.
For example, you place a bet for 'Under 10 corners' and at the end of regular time, 8 corners had been taken. Your bet would be settled as a win, even if an additional 3 corners were taken during extra time.
