I have to tell you, I downloaded both this & ClassyCoin to play tonight, and neither one will redeem any of these coupon codes. I had no problem with Grand Parker yesterday, so I'm disappointed here.
When I went to Live Chat this is what he said:
"Nick: You can receive a no deposit bonus if your account was opened through an advertisement or affiliate who was offering a bonus. These advertisements are sent out by affiliates and not directly from OnBling, so we don't know where they can be found or how much each will offer. So please check to see which advertisement you opened your account through and the welcome coupon code they offered."
