Which of the gambling game do you think that is the fastest in bringing profit base on little time duration
are you sure you understand what gambling is ? It's all about luck, and most gamblers lose, and keep in mind that the faster you want good profit, the more risk you're putting your money into, the fastest games in casinos are dice games, blackjack, and roulettes ..etc but of course the profit is not guaranteed at all.
Maybe he wants to compare one gambling game with another so he can find which gambling game can give him an advantage. But whatever gambling game he wants, it all depends on luck and as you said, the more money you put into gambling, the greater the risk of losing it. Profit won't come to you if you don't have luck. So don't think that one gambling game can give you a quick profit because it's very difficult.
