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?! 
The hint is already there that you need to try again later and if you noticed the word "please" so you have to understand that there is some slowmo in their withdrawal. Everyone here know that crypto-games.net is one of the most trusted and long running crypto casino so they will not scam someone that will lead them to lose their loyal customers and investors.
This is NOT cool...
Sometimes you need to be patient though, ask their support politely to help you out with that error.
