I have not, no. But it seems that it's actually btb88 that rebranded and is now called Maverick Games. http://btb88.com/ is dead apparently. I wonder what happened to it. I remember btb88 as a casino that requested KYC during the registration process. Although I applaud their honesty in contrast to many other platforms that ask for personal information only after a big win, it also meant that I couldn't/didn't want to make an account to check out their site.
