If you are already logged in to the casino site, authentication can be done through the query string to the iframe. . I've browsed with 3'd party cookies disabled for years and very very rarely had any problem. I wouldn't say never, certain widgets do break, but those are less than one in a thousand. Only one i can recall from the top of my head is Discus. For Discus, authenticating through the parent site will be an issue since one of the reasons for using Discus is to avoid many different logins.
