Confirmed blackjack is pretty much rigged. When you bet high you will get horrible cards and will lose or tie around 90% of the time. With low bets you can win slowly, but you will waste an enormous amount of time. And since blackjack is rigged you can only leech of bad players at poker, but they'll run out of credits eventually since they wont be getting them from the rigged blackjack, so yeah someone is probably putting in money for gambling and I'm not sure if that's legal here
