What Are Slot Machine Symbols and Payouts?

A narrow notch or groove, such as one that a coin fits into in a vending machine. Also, the position in a series or sequence:

To play a slot machine, a player inserts cash or, in ticket-in, ticket-out machines, a paper ticket with a barcode into a slot. A computer then causes the reels to spin and stops them at positions that match symbols on a pay line.


In a slot machine, symbols are the images that represent the paylines and payouts. They are a key part of the game and help create winning combinations, add to the fun factor, and make the game more exciting. These symbols can vary widely depending on the theme and style of slot game you’re playing. Classic symbols like cherries, bells, horseshoes, and Liberty Bells are commonly used as low-paying symbols, while higher-paying symbols follow a specific theme.

Modern video slots push the boundaries of themes and narratives, with many of them featuring unique symbols aligned to the game’s storyline. They may also include wild symbols, scatters, or bonus symbols that trigger different in-game features and second-screen bonus rounds. Wild symbols are similar to the joker in a deck of cards and can replace other symbols to form a winning combination. They are not available in all slots, though, and can only be used to trigger certain bonus features.


Payouts in slot machines are calculated as a percentage of the amount wagered. However, this number doesn’t tell you how much you will win in a single session, as the payouts are averaged over the lifetime of a machine. The payout percentage also does not account for the frequency of winnings, which is determined by a machine’s volatility.

The payout percentage of a slot machine is an important factor to consider when choosing which slots to play. A high payout percentage indicates that a machine is more likely to pay out symbols. However, the payout percentage does not take into account the frequency of winnings or whether a casino limits the maximum jackpot amount. To maximize your chances of winning, try playing a machine with a lower payout cap and a higher return-to-player percentage. In addition, look for a machine that allows you to wager max coins. This will maximize your chances of winning a big jackpot.

Bonus rounds

In the world of slot games, bonus rounds are exciting, captivating features that add excitement and potential for big wins. They are often triggered by scatter or other symbols, but they can also be tied to the game’s theme. They range from free spins to jackpots and pick-and-win games. Some offer progressive jackpots that can reach $1M or more.

The best way to determine the likelihood of triggering bonus rounds is by reading the game’s paytable. This can be found in the main gaming interface, usually next to the settings, options, autoplay, or help buttons. Look for information on the hit frequency and RTP rate to see how likely it is to trigger these features.

More and more slot developers are adding the ability to “buy” a feature round, giving players a guaranteed chance to enter the bonus round for a fee. These slots are called feature buy slots and are becoming a favorite among players.


Regulators make sure that slot developers follow strict rules when they develop their games. This is important because if they fail to comply with regulations, they can face fines and other penalties. The game’s programming code is inspected and tested by regulators. It is also protected to prevent tampering. Most online casinos voluntarily follow Las Vegas rules and regulations in order to stay competitive.

Slot machines must be regulated to assure fair play and player protection. This is accomplished by limiting the amount that the machine pays out on average. This also helps entities that tax a brick and mortar casino to easily assess the amount of taxes they will receive.

The theoretical payout percentage of a slot machine is set at the factory when it is built. However, changing it requires a physical swap of the EPROM or non-volatile random access memory (NVRAM). The new software must be approved by the gaming control board before it can be installed on the machine.
