Forget about looking to those imaginary casino's that doesn't have house edge or 0% on it. There's no way for them to operate in their future business if they'll just offer their service for free. It's like that they'll only going to profit from the losers and it's risky for them. And if you have found out that there is a 0% house edge casino, don't believe with those as they are suspicious because it's too good to be true.
