One of the most important things to remember when playing slots is to play responsibly and not chase small wins. It’s easy to get caught up in the excitement of the spinning reels and the potential for big payouts, but it’s crucial to set realistic limits before you begin.

This is especially true for higher-denomination machines, which tend to pay out more frequently than lower-denomination ones.
