Symbols are one of the most important elements of slot machines. Depending on the game, different symbols can trigger different bonus games and features. While the standard reel symbols include playing card and fruit symbols, you may also encounter bonus symbols. These symbols are used to trigger bonus rounds and are different from Scatter symbols.

Bonus features

The bonus features of slot machines trigger when a player gets a certain combination of symbols on a payline. This combination can be a scatter, a wild symbol, or a dedicated symbol. These symbols can trigger different special features such as multipliers, free spins, and jackpots. Sometimes, players can trigger the bonus feature by getting three of these symbols on a payline. Alternatively, they can trigger it by collecting a series of items over a number of spins.

Payback percentage

The payback percentage of a slot machine refers to how much of each dollar wagered is returned to the player. The highest percentages are generally found in highly competitive areas, while the lowest ones are typically found in less competitive areas. A slot machine with a low payback percentage typically gives back only 25 cents for every dollar wagered.


The bonus games offered by slot machines are a unique way to keep players engaged and boost their chances of winning. The minigames are usually triggered by specific symbols, but some are also randomly triggered. By playing these games, players can increase their chances of winning as well as unlock additional features.

Location in a casino

Many players believe that the location of a slot machine affects its payout, and that the machine at the end of the casino is more likely to pay well than the one in the entrance. However, this theory is inaccurate. While there were some variances in slot payouts ten or twenty years ago, nowadays, most casino floors have a consistent payout rate.
