I feel casinos use different reward patterns to pay their users. Some casinos offer a flat rate for rewards such as cashback or loyalty points, while others may offer tiered rewards based on the amount of money a user spends or their level of play. casinos may also offer bonuses for specific games or events, or may offer personalized rewards based on a user's individual playing habits. Ultimately, the goal of these reward patterns is to incentivize users to continue playing and spending money at the casino
