The only fully decentralized casino game that I can vouch for is EarnBet casino platform, has a non custodial account system, fully licensed by Curacao, Provably fair low house edge games (0.5%), has 6 state of the art games and you can play this games with over 14 different cryptocurrencies, investors who cannot play games are also cashing out from holding/staking $BET token that pays $BTC & $ETH as it's dividends, in just two over $10 million has been paid out as dividends.
