If I could give no start it would be a great option but am giving 3 if you need assistance the chat option they give you is of no help the can't even update your email address on thise survive they offer you need to email them then they can't even do the job right still on my old email address when I asked fore it to be updated more then 2 years ago I have only one money ones at thise casino they did pay out but with the amount that people need to deposit before wining some money it's not worth it so if you need help with your account chat assistance kan not do anything good luck if you deposit money here to gamble
