It's all a matter of chance. There are no blackjack- or video poker-like strategies that can cut into the house's mathematical edge. Odds on slot machines are unchanging. There's nothing you can do legally that will change the outcome, though scam artists sometimes have succeeded until caught, arrested and imprisoned.

Gambling is not a good alternative for earning extra cash. Each game you play at a casino has a statistical probability against you winning. Slot machine odds are some of the worst, ranging from a one-in-5,000 to one-in-about-34-million chance of winning the top prize when using the maximum coin play.
