I've never been a fan of this types of gambling games. Using animals to compete with another species or the same one.
I know horse racing but even before it didn't give me the fun to see a horse being lashed by the racer just to speed it up. But perhaps this could be normal in rural places where people don't use internet or do not have the knowledge about card games. I may agree with what they will do but if it someone who has knowledge about other gambling games and has access to it, why choose animal races or fights?
A good options is near you so just use that kind of method to gamble yourself away.
Horse racing and cockfighting are those that are very common to most third world countries.
They love betting, especially those who are residing in rural areas. Some, if not most, are depending on their livelihood
with this kind of gambling.
Not fan of Cockfighting but with horse riding sometimes I also bet with it and enjoy even I don't win yet.
