can anyone recommend to me how much is the capital or starting money is good for slot games?
Are you serious about wanting to know the capital in the King Kong Cash slot game, I thought you knew the King Kong Cash slot and had played there, in fact I was wrong.
You simply see below the capital in need.

If you want to try, maybe you can do that, what is clear is that every game has loss and luck.
I had the privilege of visiting a physical casino recently and it seems that most people avoid using such. Generally, most of the gamblers I have witnessed focused more on card games. Rarely do I see people gambling on slots.
The question is- why do people avoid gambling into slots? Though I do understand that the jackpot is indeed high, is the risk of losing money too high that it outweighs its winnings compared to gambling on card games?
