It appears to me that this casino is a decentralized or semi decentralized casino as I saw the "connect wallet" tab at the top.
I don't think there is any casino that is semi decentralized. It is either centralized or the other and it is hard to see decentralized casino in this days. And from the wallet I saw from this casino "wallet connect" it is already KYC casino because okx is CEX and I believed others too.

Coming to the Op I welcome you to the forum as others. Do well to upgrade the Op with the some images and that will need some sats unless you are a Jr Member.
Thank you, we'll definitely take note of this and improve for all further posts. That being said, I'd like to answer your statement regarding the KYC. We the casino do not have access to any information OKX or any other wallet may ask you for. The Slush wallet is currently our wallet of choice being that it is a Sui native wallet and we're built on Sui, and they don't require any personal information.
Again I'd like to reiterate if other wallets do ask fro KYC like OKX in your example, we don't have any access to tha information, and you as the player will always have full custody of your funds while on our site.
