I usually don't post on forums, and today when i got the email about the new casino, I actually looked at the address to fast, and thought I was in different forum called casinomeister.
As for Palace of Chance, at one time they were a good casino, but that was over 8 years ago. I played there for a while, the real slots hadn't even come out yet, and then the first 3 were released. cleopatra first, and then the next two were caesers and one other, i think it was aztec. Anyways a little while after this, they were having financial trouble. Someone bought them, and from that point on it went downhill, especially after they became a group.
You mentioned that they have a lot of free coupons. Well this is one of the best ways to tell if a casino is rogue. The more "free money" they offer the worse your chances are at doing well there, and the higher % chance that the casino is rogue.
Cool Cat casino falls into this category as well. And another big one is Prism casino.
