A Cashback online casino bonus is a reward or incentive program offered to players by certain casinos for playing their casino games. It is a way of thanking a customer for their loyalty and dedication to the casino. The bonus is typically provided as a percentage of the total amount the player wagers in the casino over a given period of time. To qualify for the cashback bonus, a minimum level of activity must be achieved. The bonus usually comes in the form of a percent that is paid back to the player’s casino account.
