I think the main issue with sub domains are duplicate content. In other words, if you have casino.yourcasinoportal.com with the same content as your main pages there would be a problem. Otherwise, I have seen many subdomains in google results.
Granted the sub-domain content theoretically resides in a directory, but, it points to whatever.yourdomain.com I’d think then that it would be more favourable to use a sub-domain as apposed to a directory.
