I apologize, I thought it was Starcasino.be because it's also a Belgian casino. I also can no longer access my casino777.be account. I've had an account since the casino opened. I'm receiving the same message as you.

Angel vs Sinner 876x  

I jus tried to log in again now and get this...

After a big win, I continue playing since the slot is paying out. If after 100 spins I find that the game isn't paying out, then I stop.

I'm not from Belgium and my account is still open. I even receive promotions by email.
