Many new players don’t understand how slots work, which can lead to frustration and a less-than-pleasant casino visit. If you don’t understand how the machines pay, you can easily get carried away with the excitement of watching the reels spin and hoping for that jackpot to drop.

Understanding this can help you manage your bankroll and choose a machine that matches your gaming style.
