When playing a slot, a player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode. The machine then activates reels that stop to rearrange the symbols and allow players to earn credits based on a paytable. The symbols vary depending on the theme of the game and can include classic fruits, bells, stylized lucky sevens, or other themed images. Most modern slots have a computer that controls the outcome of each spin.

The result of each spin is determined by a random number generator (RNG), which records a sequence of numbers and then chooses one of these to correspond to the position of the reels at that time. This process occurs thousands of times per second, so the odds are that no two consecutive turns will produce the same result. When a winning combination appears, the machine will issue a payout according to the paytable.

A pay table is an informational guide that explains what combinations pay and what can trigger bonus games on a particular slot game. It also includes a range of other information, such as the RTP and volatility of the game. Some modern video and online slot games use an on-screen pay table, while others offer a traditional printed version with columns and rows. In both cases, the information can be helpful to new players or those who haven’t played a particular game before.
