Penny slots are games of chance and the results of any spin are dependent on luck, but there are some tips to help you play more responsibly. First, always read the rules before playing. This includes reading the paytable and understanding the bonus features. In addition, be sure to check the return-to-player percentage (RTP).

Another tip is to only risk a set number of units in a single penny slot session. This will ensure that you won’t lose more than you can afford to. Some sites even recommend setting a loss limit for your sessions. You can do this by dividing your bankroll into 100 units and only risking them when you have reached the desired amount.

Lastly, never increase or decrease the size of your wagers based on past results. This advice is based on the mistaken assumption that past performance has some influence on future outcomes. In reality, each spin of the reels on a penny slot is an independent event. Therefore, changing your wager size based on past results will have no impact on the outcome of the next spin.
