This number represents the average percentage of money that a machine pays back to players over time. Using this metric can help you determine which slots are fair and offer the best odds.

In general, the higher the payback rate of a slot machine, the better your chances of winning. However, this doesn’t mean that you should avoid playing low-paying games completely.
