Key Takeaways. 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.

Therefore, there is no way to predict when a slot machine is going to hit, and any strategy or system claiming to do so is likely to be based on superstition rather than fact.
