Overall, if a Cashback Bonus is paid out in cash, as is most common, there should not be any wagering requirements attached to the bonus, as the player will already have played through their funds. Since a Cashback Bonus is calculated on casino losses, adding wagering requirements should be unnecessary. There are different types of Cashback Bonus, so it's always worth checking the Terms and Conditions carefully before fully committing to a Cashback Bonus offer.
