I like not just spinning the reels, but also participating in promotions, getting cashback, free spins. But often bonuses on sites are either one-time or have such a meager effect that you don't use them. Maybe someone can tell me where bonuses really help you play longer?

I recommend trying parimatch-download.in — they have a very balanced bonus system. Free spins are given for registration and regularly for deposits. There is a cashback, and it is not a fiction — a couple of times it really saved me when I was in the minus. Plus, there are constant promotions and tournaments where you can win real money, not candy wrappers. I even won 15 thousand in a tournament once — a nice bonus.
