An online casino cashback bonus is a bonus given to players who have lost money while gambling. The size of the cashback bonus is usually a percentage of the amount lost, and it is given back to the player in the form of cash or bonus credits.
The cashback bonus is a way for casinos to encourage players to keep gambling, even when they are losing. It is also a way to reward loyal players who keep coming back to the casino, even when they are not winning.
The cashback bonus can be a great way to recoup some of your losses, but it is important to remember that it is not a guaranteed win. You still need to be careful with your money, and only gamble what you can afford to lose.
