Here it is the list of crypto sports book. But the OP wants specifically casino which provides KENO game. Though this list is good, but I highly doubt that any site will have casino games like KENO. I just want to know that, how OP is claiming that Stake has rigged the games without any proper evidence. I have been playing at Stake for more than many years and till now haven’t faced any single issue with it. If you really need an alternative, then try Bitsler. It’s another casino who is into the business for many years. So do check them out.
You're right that the guide is curtailed towards sportsbooks but they all have casinos with keno except for mBet. I just threw the link up there to make it easy for posters to find ANN threads and take a look for scam accusations in case they feel like doing more research.
