Of all the things you want to look for, it is very difficult to determine the right casino with the features you want, even I myself also have difficulty finding PVP games, until now I haven't found the right one, if you try to play slots, try betting, it won't disappoint you, It's just a monthly bonus, pay close attention and it won't disappoint you
I think most casinos offer slots these days and the legit ones aren't going to scam anyone. The OP is looking for many features and I'm very sure that there are a few casino sites that offer all those features on their platform but I won't recommend any casino here as that is not going to be helpful to suggest one a two casino.
I think it should be far better if OP give some time to research about those casinos by reading a few announcements threads on this board as that's going to be the best advice for the OP. However, it may require him/her to spend sometime by reading the threads and also reading some reviews about those sites. But, surely the time spent on reading those threads will help OP to understand in deep sense about those casinos.
