Also, if I'm not mistaken they also run another casino dPlay, though, haven't tried neither of them. But I kinda doubt that's possible to run multiple casinos smoothly when there is just two people behind the curtains.
You are right about Dplay.
Dplay and Club Riches both are owned by wetsuit and according to the post made by TheQuin around two years ago, wetsuit may be involved in more businesses too.
He's currently spending a lot of time on diversification with the new businesses. You've seen Dplay and Club Riches but there's also a lot more coming.
