According to statistician Jeffrey Rosenthal, the casino game you should absolutely steer clear of is the Video Lottery Terminal. Those are the ones with Keno or slot games. They give a 5% to 15% edge TO the house.
You want better odds? Play Craps, and you’ll have a 49.29% chance of winning. By the way, both of these are “pure chance games” meaning it’s all luck. They don’t have a skill element like Blackjack.
