I have my favorite providers - Push Gaming, Nolimit City and Pragmatic Play. But some casinos either don't have all of them, or the choice is poor. I want to play proven slots, and not what "is". Where can I find the maximum variety of providers and at the same time normal conditions?

You should definitely check out http://kingschancecasino-au.com/ I love variety too — and I can confirm that they have one of the widest selections. There is definitely Push, Nolimit, Pragmatic and a bunch of others: Play'n GO, BTG, ELK and even rare studios. Convenient filtering helps you quickly find the games you need. Slots launch without delays, and there is no feeling that something is cut. Plus, they often add new products — I noticed that they really follow the releases.
