Casino slots are a staple in online casinos, but do you know how they work? Whether you are new to casino games or a seasoned pro, understanding how slots work can help you make better decisions about your play.

There are many different types of slot machines, from the classic three-reel variety to the more complex video versions. Regardless of the design, all slots operate on the same basic principle: a central computer generates random numbers for each spin, which then correspond to symbols on the reels. When a winning combination is generated, the player receives credits based on the pay table. Traditionally, players insert cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode. A lever or button (either physical or on a touchscreen) then activates the reels, which stop to rearrange the symbols and award credits based on the paytable.

For generations, players were told that maximum bets brought the highest payback percentages. While this was often true on older three-reel machines, it is not always the case with modern video and online slots. In fact, maximum bets may actually cost you more in the long run because of the incentives built into the pay tables.
