I got to start a thread regarding the problems I encounted with RedKings. It may help other players.
I made a $25 deposit to Red Kings from my Mastercard. I played for awhile but I began to be very suspicions regarding what I saw. Therefore I decided to close my account and play at FullTilt again. I like FullTilt tables to play at. So I began trying to make a withdraw of the $24.?? the balance I had left. The only link I had on my withdraw page was a wire transfer. So I tried it, no luck, there was an error message coming up each time I tried. After 3 days trying to get help from support, I got the complete answer. I found out there was a $100 dollar minimum to use it.
Wow, now I'm totally high and dry, I either go back to the tables or just walk away from the money. This also added much more suspicion to my opinion, there criminal activity present in this Red Kings site. Besides, this site has taken away the freedom of a human being of leaving and quiting when he wants. Because they got mimimum levels attached to all their withdraw, this does leave a player without the rights of freedom of choice, where as one should be able to quit and withdraw remaining funds without facing problem.
This is what I'm talking about, walk into an off the street casino, walk up to the cashier and buy chips. When you are tired, walk to the cashier and get paid for each chip you have left, even if it is only one, then walk out to the street. You are free to do as you are pleased. Not with the online site, they got a mimimum, holding you at ranson, forcing you to gamble again.
If they (Red Kings) had a cheque paying option, I would have use it, no nothing available. Love to hear from other player who got stuck in the con games of these sites.
SO BEWARE WHERE YOU PLAY, SOME SITES ARE FULL OF SURPISES.

Deposit $100, then withdraw it all? Is there a fee for deposit/withdrawal?

This a standard procedure for most sites. having a minimum depo and withdrawl limits. I'm not sure why you are so surprised at this. It behooves anybody giving money to an offshore gambling sight to closely read all their rules and regs before sending them the money.

I do thank you for posting this though, as it does bring up that point.
