How do slot machines work in casinos?

Slot machines are some of the most popular games in casinos around the world, and the features they offer are exciting. Essentially, slot machines are easy to play, but they operate on a complex system involving the principle of chance and mathematical calculations.

RNG – Random Number Generator

In the world of digital technology and online gaming, the acronym RNG stands for Random Number Generator. This technology plays a vital role in many fields, including online gaming, cryptography, scientific research, and more.

An RNG is a mathematical algorithm or physical device designed to generate sequences of numbers or symbols that appear to be completely random. This creates a high degree of uncertainty and unpredictability of the outcome of any process involving random elements.

Each slot machine is equipped with RNG. These numbers determine the outcome of every spin. When you press the spin button, the RNG stops at a number, which determines which symbols appear on the reels. 

It is impossible to influence the operation of RNG, and if somewhere you see information that the more you play or bet, the higher the winnings, then you must understand that this is just a myth.

RTP – Return to player percentage

When you play at a casino, be it a slot machine, roulette or card game, you need to know an important term: RTP or “return to player percentage”. RTP indicates how much of a player’s bet will be paid out over time. For example, a slot machine with an RTP of 95% means that on average it pays out 95% of the money deposited to players as winnings, with the casino keeping the remaining 5% as revenue.

RTP is an important indicator of how “profitable” a slot or casino game is. The higher the RTP, the higher your long-term chances of winnings. Players often look for high RTP games to maximize their chances of profit.

RTP is not a guarantee of individual winnings as games are still based on randomness.

Understanding RTP is important because it helps you make better decisions and manage your gaming capital more effectively. Please be aware that the RTP for the same slot may differ from one casino to another as each casino presenting the game has the right to regulate the RTP.

Volatility


Volatility in the gaming world refers to the degree of risk or uncertainty associated with a particular game. This is a measure of how much and how quickly the results of a game can change. Games with high volatility tend to have larger and more unpredictable swings in game outcomes, which can result in larger gains or losses in the short term. On the other hand, low volatility games tend to produce more stable and predictable results with less fluctuation. 

How to choose a slot

Typically, each slot machine has an icon with a question mark or similar, and below it you can find detailed information about the rules of the game. It includes information such as the game’s RTP, volatility, whether you can get free spins, how many free spins you can get, and what symbols and their combinations are used in the game.

There are usually five types of symbols in online slots:

  • Wilds: replace other symbols to form winning combinations.
  • Scatters: trigger free spins or bonus rounds when a certain number is reached.
  • Bonus Symbols: Activate special bonus games or features.
  • Multipliers: Increase payouts on winning combinations.
  • Standard Symbols: Images based on the theme of the slot that provide winnings for matching combinations.

Thanks to ongoing technological developments, slot machines are likely to remain a central part of online casinos in the future.
