A cashback bonus is a type of reward that gives players the chance to recover some of their losses when playing at an online casino. In essence, it is a percentage of your losses back as a bonus. This bonus often takes the form of an added percentage when you make a deposit. That means your regular deposit is multiplied by this percentage and you get the extra money to play with. It is important to note that cashback bonuses can be structured differently from one casino to another, so it is best to read the terms and conditions of the promotional offer to get the most out of it.
