Casinos typically consider factors such as frequency of play, amount wagered, and overall spending when determining players' eligibility for rewards and tier upgrades. They may also take into account factors like length of membership, level of engagement, and specific game preferences. Essentially, the more you play and spend, the higher your chances of earning rewards and advancing through tiers. However, casinos also value consistency and loyalty, so players who consistently visit and play may receive perks regardless of their spending level. What do you think about the balance between rewarding high spenders and fostering loyalty among all players?
