I think most casinos use recognition tools such as loyalty programs, VIP clubs, comps, and rewards to run their affairs. These tools aim to attract and retain customers by providing incentives for them to keep coming back to the casino.Loyalty programs typically offer rewards based on how much money a player spends in the casino, while VIP clubs and comps provide special privileges and freebies to high rollers and frequent players. Rewards can range from free drinks and meals to free hotel stays, cashback, and even exclusive event invitations.
