I have heard from the history of my country that in the past cockfights were organized in different parts of our country. Although the game is not currently held but bull fighting is still held in different parts of our country but I don't know if any of these games are announced on any gambling site.
Bull fighting may still be a traditional gambling game so maybe we will have difficulty or even not find it on the online casino list, even in local online casinos for people from that country. It seems that several traditional gambling games still exist today because there is still interest from local people in betting on these traditional gambling games. And including cockfighting which still exists in several Asian countries and is entertainment for the people there. And if cockfighting is a culture, it may be in the country for the long term.
online cockfighting is legal in several countries and so you can easily find it over the net. and still raking billions of dollars. and it seems that PH is leading on this one. then india, indonesia cuba, or france.

As a local resident of PH, I think the masses in our country are more familiar with cock fighting rather than poker or at least in my area. There are at least 2 physical cockfighting arena in my city and it's neighboring city and there's no legal casino around. I live on a province in the Philippines and it is easier to find cockfighting arena than casino to be honest. Even my late grandfather raise cocks to fight in those arena! This is why I didn't get shocked when an online cockfighting casino rapidly grow in our country. I think cockfighting is a norm here.
