Okay, but is this a legit site? Not much of a gambler myself though I've tried a few ones with free credits. So, you just play like you would normally play Minesweeper?
He said it's a scam, OP is nothing but a shiller.
it's scam site I experiment it !!! 
Good to know that you are not the type that will want to gamble all you have earn. You took a very intelligent decision just that I have no sMerit to give if not , I would have love to give you one. Hope the new site for which you made this amount is still accepting new players because I will love to try them.
Don't bother to send him a merit and besides he said that because out of greed he lost his money and just withdrawn 0.052btc
only won 0.052 now.. lost in greed
