But the biggest reason is probably that its hard to make a skill-based game into something luck based.
Cockfighting is more of a luck-based game though your bird has a high chance of winning if it is well-trained but in the end luck should be on your side most of the time to win.
Is it though?
One rooster is not the same as another rooster. If anything that is what I imagine to be one of the most exciting parts of the game? To bet on a better rooster? Thats why in real life cockfighting the strong roosters are very prized. If you wish to emulate that experience and offer it as a game on a gambling platform, then you cannot make the digital version luck based. Otherwise it just becomes a simple dice game but with animated roosters...
Not that I am an expert in cockfighting. Far from it, actually.
Based on my experience my father really having fun with this game and he is the one make a condition with the cock fighters this thing has a lot of preparations like feeds, vitamins, vegetables, syrup and etc to increase the boost and capability of the chickens to make sure they are getting ready to the fight there's some different breed of it depends on the colour like red, orange, and white also wit their legs if this is white or brown and also you can see the body of the chicken is well good if you touch its wings, head, and under part of it and if the body is firm or not.
