Well without global audience for those games, I hardly think casinos would actually add them. Afaik, those games are only relatively popular in the Philippines, and not really in other countries. As for crypto being used in gambling apps, I mean, we have crypto casinos, so I don't think that's anything new. It's just that those games aren't really included in the roster of games that crypto casinos have, and hence why you don't really see them that much.
I don't know any of these games. Are they very popular? Playing new card games is always fun, but I wouldn't gamble on it. I only consider gambling on games which I know well and where I think I have an advantage. That is why the only two card games I play with money are poker and blackjack.
They're games popular in PH. Looked it up, and it seemed like Pusoy and tong its originated from there, Tried looking up luck nine and didn't really have any luck with it though.
