It's as you say. As I mentioned before, it is always a good idea to look at the Terms and Conditions before a player decides to play in the casino. Whether it's for any reason, and I think this particular one about game providers is one that players often run into.
Anyway, a good point you mentioned is that sometimes it's easy to check with live chat about the situation with game providers. But of course sometimes the casino can't do anything about it if the game provider doesn't allow certain games for them.
In this case, I agree with the opinion that you learn by making mistakes and I think you will definitely be more careful in the future regarding this particular situation.
I also think you added an interesting point at the end and maybe I will try it sometime.
I would like to ask you which game providers you like, since you mentioned the ones that are banned in Germany and the ones you don't play? 🙂
