So far so good. Simple to sign up, transfer some money into a wallet there, etc. Fun games, easy to use, some decent signup bonuses and such. I'm digging it. Of course, follow the rules of safe gambling... only play with money you can lose, view it as a game and the money as a fee so when you lose it you're not mad. My only complaint is that I'd be interested in a craps game... but this seems to be missing in most online casinos so not really surprised.
