I am very familiar with the games you have mentioned and I can say that you are from the Philippines as well. Well, I had an experience of betting with the color games with one peso bill and made that capital 150x or more (i can't recall) but I really won big time. I was just a ten-year-old those days but I can't forget that moment. For me, the techniques in that kind of local game are to invest 10% only of your capital and use it as your bet. You have to be patient and keep on betting 10% consistently so that you can earn a big profit and don't lose.

Maybe your observation is correct but I am not yet convinced since my uncle owns one and I don't see any hack well, in fact, I see them going home with a bad mood because of losing. Yes as an owner of the gambling hosting, you also bet with the game but your capital must be bigger too.
