best vip loyalty program if you're grinding regularly

I play a lot of roulette and slots, mostly sticking to the same site instead of hopping around for promos. I know most places have their VIP setups, but it’s hard to tell which ones actually pay off in the long run if you grind at mid to higher stakes week after week. Some give cashback, others focus on free spins or the odd trip, but honestly, I mostly care about solid cashback or real cash rewards over random merchandise or event invites.

I’d like to hear about others’ experiences. Has anyone seen better returns at places that do tier-based multipliers versus flat-rate weekly cashback? Also curious how strict the requirements are for VIP hosts and how personal they get about your habits, especially if you’re not throwing down super high roller money but still playing steady. Curious what’s working for others who play similar games and amounts.
