Never heard about any of these 3 games  I know that there are many card games out there which are played around the world and have different names. Maybe you could explain a little these games? If they are competitive card games than maybe casinos could pick them up. The beauty about poker is that the rules and the name is the same all around the world. So when two people from different continents meet and don't speak any common language they could atleast play poker together.
