I play on cloudbet and windice. And I can say that they are both legit. Wide variety of casino games on cloudbet and an easy to win roll dice on windice. And also I think you need to update this list. You might want to check windice and also the stake.com to be added on your list. They are good too. Try those sites so that newbies can also know if it is good or not.
I have gambled on Cloudbet for almost 6 months already and I encountered a problem only ONCE and that problem has been solved after a few hours only.
The support staff is good. They chat immediately when you needed help. Aside from that problem I encountered, I didn't face any problems at this moment. They are surely a legit gambling site.
