What is RNG?

RNG denotes a Random Number Generator, i.e. a process in which sequences of numbers are generated at random. They do not follow any formula or system and are not influenced by external circumstances. RNG can therefore be used, for example, in computer simulations, in various types of modeling or in gambling. This applies to roulette and blackjack, as well as to slot machines.

Concept and definition of RNG

An RNG generator is a type of microprocessor that generates hundreds of random number sequences in just one second, producing billions of combinations in total. Many current technologies, including gaming machines, employ such an algorithm. Just be aware of the difference between true and pseudo-random random number generators.

A true random number generation is, for example, rolling dice or drawing lots. But if we want to apply this principle in programming, we need special hardware, which is available only to a few military and commercial institutions that work with strictly secured systems.

In most cases, so-called pseudo-random numbers are sufficient. Their sequence can be created by almost any generator, in such a way it resembles random numbers as closely as possible. The only problem is that they are periodic, so they repeat themselves after some time. It is, however, sufficient for the needs of computer games and slot machines.

RNG in the world of slots

RNG is essential not only for math wizzes, but also for fans of slot machines and gambling entertainment overall. Modern versions of slot machines have built-in software that works on the RNG principle. This control center then has control over every game and individual spin, and without undue exaggeration is referred to as the heart of every slot machine.

Thanks to the use of RNG, today it no longer the case that a machine would give out money only when it is full and needs to empty out. And neither does anything depend on when the jackpot was last hit or how long it's been since the last win. Modern casinos really give everyone the same chance.

RNG and fairness

If the chosen casino employes RNG, you don't have to worry about its fairness or reliability. Currently, every slot machine must have this function, whether it be a physical slot machine or an online one. In addition, all these systems must go through a rather complex testing process by law, which is why casinos and gaming houses demonstrate their use of this technology with various licenses. If they don't have a certificate or won't show it to you upon request, it's best to avoid them.

Even when using RNG, however, casinos need to remain profitable. So related to this is the RTP (Return to Players) check, which is a theoretical value that players should approach according to mathematical probability.

And last but not least, it is also a matter of choosing slots with the corresponding volatility. This term is borrowed from the real world of finance, notably investing. In the gambling world, it basically denotes the same. The higher it is, the more you can win, but you will have to wait a bit longer than with machines with lower volatility. In their case, luck will smile on you more often, but you with smaller winnings.

Role of RNG in bonus games

You get not only wins in the base game, but also bonuses on regular slot machines based on RNG. This means that they are determined only after your spin and, just like in mathematics, the situation balances out gradually. It is therefore likely that after the free spins and other benefits there will be a less successful period and so this pattern continues back and forth.

Hopefully, we have shed some light on the issue of the random number generator. After all, it is an important element that all slot machines in licensed casinos and gaming rooms have today. And it certainly doesn't seem as though it will get replaced by another technology anytime soon. Rather, we can count on its gradual improvement.
