Those are good sites but one thing you will have to know is that there are times it will reach and you will just be the one losing to them. When times like this comes is better to just quit and look for something else to participate in unless you just want to keep on losing there. CloudBet and PrimeDice are the only sites that I'm very are really good on this list you have here. I have also seem people that claims that Bet365 is a good one but I don't really know if that's true. Then as for the remaining two, I don't know anything about them at all and I haven't heard of them before.
