Welcome to the forum. Do you have everything on the online casino website about cookies and ISMS policies, but there is no section of the terms and conditions of service and the KYC policy, in any case, I could not find it, is it planned to be added or are they available only after the registration process?
They are game provider of slot for online casinos as what you read on the subject/title and as mentioned on earlier reply of OP. They are not a casino so KYC isn't a thing for any users unless you have a casino business trying to partnered with them that of course, requires business related documents and stuff.
