I'm very sure that casinos use IP addresses to customize the layout
I think OP wasn’t referring to IP address but to intellectual property games. honestly, I have no idea if these games are already in casinos or if they even could be, that’s why I’m curious .. I’d like to know which casinos are already offering them.
Personally, I’ve got a lot of favorite games I used to play when I was younger, before I even learned to gamble online. If those kinds of games are being adapted into casino formats, that’s pretty interesting and definitely worth knowing about.
