How do slot machines work?

Slot machines comprise of three or more reels, or vertically placed columns with rotating symbols on them. Physical slot machines are limited in the number of reels and symbols, but their digital counterparts could potentially have more reels and a much larger number of symbols offering thousands if not millions of winning combinations (also called “paylines”).

The winning combinations are generated by the Random Number Generator (RNG), which employs sophisticated mathematical formulas when choosing a winning combination. 

Whether a player wins or loses is determined by the RNG the moment they place their bets, and as such is impossible to predict the outcome. Many players believe that winning chances increase if the wager is bigger, but that is not always the case. 

It is possible to enter a bonus level or even a jackpot level with a minimum bet. This depends on the slot’s mechanics.

Types of slot machines

Slot machines come in many shapes and forms, with different features and payouts. They can be classified into several categories.

Progressive Slots

Progressive slots are linked machines that accumulate a joint jackpot. The jackpot increases over time, depending on the coins being played.

Wild Play Slots

Flashy slots, popular for their increased chances of winning thanks to their Wilds acting as substitutes for other symbols. In certain cases, Wilds could open a bonus levels or special game features.

Video Slot Machines

A slot that emulates a real spinning wheel. This particular type of slots could offer a large number of paylines, and an even bigger number of winning combinations. Often, these machines will bring players bonuses in the form of progressive jackpots, free spins, and multiple bonus games.

Touch-Screen Machines 

Since its inception, touch-screen technology found its second home in the casino industry. It was almost immediately implemented as an interaction method in newer slot models. The new slot variants proved quite popular with players who appreciated their slick design and comfortable setup.

3D Slots Machines

Slots offering three-dimensional graphics are a hot commodity these days. The cutscenes and animations look more live-like, the colors are brighter, and in general, these cabinets offer higher engagement thanks to their inconvenient and innovative gameplay mechanics.
