Hi Henry. Good question, i was asking myself the same question about 3 years ago. I tested around 10 casinos, only 1 was an out and out scam but it is clear to me some are better than others. The one i ended up staying with was Luxury Casino.
They had a good sign up offer, it was spread over 5 deposits but it adds up to $1000, its not as simple as $1000 welcome bonus like they advertise so be aware you do need to deposit 5 times to get it all but if you’re playing regularly then this will happen naturally.
Their customer care if really good, its 24 hours and almost no waiting times like other casinos where their customer care can be pretty much non existent.
As for roulette, they have everything from digital to live (including European & American roulette) and all sorts of cool variations of it.
