Slots are the most popular machines in casinos and can be very exciting to play. However, if you’re not careful, you can easily spend more than you intend to and get into trouble. That’s why it’s important to set limits for yourself before you start spinning. Also, remember to take a break occasionally and not let yourself get too greedy or bet more than you can afford to lose. These are the biggest pitfalls while playing slots and can quickly turn what should be a fun experience into one that makes you want to pull your hair out.
