Everytime I try to withdraw(and I am WAY above the minimum) i get the following "error" message... "Failed to send confirmation mail, please try again later." WTF?! 
This is NOT cool...
This is NOT cool...give it sometime , cryptogames is so far the most trusted investor based games and this error maybe temporary
a couple of days ago I made over 0.15 BTC withdrawal and got it in less than 2 minutes , so everything is fine just give it time
try asking in their chat
