All about RNG (random number generator)

14.3.2022

If you play at our recommended online casinos, you can be sure that you will get fair play. From a gambling perspective, this means that every single card draw, spin on the slot machines or ball roll on the roulette wheel will be completely random and therefore unpredictable for both you and the gaming operator. And who cares about randomness in casino gaming? Well, the RNG (random number generator). In this article, we’ll take a closer look at the RNG.

What is an RNG?

RNG or random number generator is a part of a computer program (software) that makes sure that the results of casino games (for example, the numbers of cards dealt or the stopping of the reels on slot machines) come completely randomly, regardless of previous results and regardless of any other circumstances.

Why is RNG used?

If RNG were not used in online casinos, the results could be misused, both by the casinos themselves and by the players. Casinos could “manipulate” the results to get more money out of the game than they are entitled to given the payout. Players could then look at the behaviour of the casino games and figure out how to repeat certain outcomes, which could tilt the odds of winning in their favour (and thus cancel out the house edge altogether and achieve a positive ROI while playing).

Is it possible to win against a random number generator?

Theoretically, maybe yes, practically no. Since a random number generator is still driven by mathematical operations whose results are always exactly given, theoretically speaking, the results should be able to be compared backwards to calculate future results. In practice, however, these operations are so complex that you would need several years of supercomputer-level computing power to calculate future results.

What does the use of RNG provide?

The use of a random number generator is mandated by the authorities, it is one of the conditions that online casinos must meet in order to obtain a license to operate gambling. In addition, the use of the random number generator is continuously monitored, so it can never happen that a licensed casino does not use it.

Which online casinos use RNG?

RNG is used by all casinos that treat players fairly. The use of a random number generator is one of the main requirements for obtaining a gambling license. All licensed online casinos use the Random Number Generator.

On our website, we only recommend online casinos that use a random number generator. This is because only these online casinos guarantee a truly fair approach to gaming. If you want to make sure that you won’t be cheated at the casino, we recommend playing at the following online casinos:

What games are RNG used in?

The Random Number Generator is used in all casino games that are based on random results in the real world, i.e. slot machines, blackjack, roulette, craps and more. The random number generator is also used in classic poker, although this game is not based purely on chance. In contrast, the random number generator is not used in sports betting, where results are generated based on actual sporting or social events.

Is it necessary to change the game strategy because of the random number generator?

There are two different answers to this. If you are using a roulette strategy or a video poker strategy, you do not need to change it because of the random number generator. Everything works exactly the same. However, the situation changes dramatically if you are using a card counting strategy in blackjack. This is because card counting in blackjack is completely ineffective due to the random number generator – the random number generator calculates each new move, regardless of previous moves. This means that no values disappear from the imaginary deck of cards and therefore the chances of hitting a win do not change.

How does RNG affect RTP?

The random number generator is programmed in such a way that it covers the random occurrence of numbers and therefore the pre-set RTP. The RNG therefore prepares the conditions for the pre-set RTP to be met.

Final summary

Random number generator is an absolutely indispensable software that guarantees completely random occurrence of results in casino games. Thanks to this software, players can be sure that the casino is treating them fairly. However, the use of RNG is also in the interest of the online casinos themselves. This is because the software ensures that the results in each game are completely illegible, so players cannot take advantage of any pattern of numbers and thus cannot tilt the odds of winning in their favour. A random number generator is thus beneficial to both parties. Meanwhile, from a player’s perspective, you should always try to play at online casinos that use RNG. Casinos without a random number generator are acting illegally and are very likely to take advantage of their misconduct to enrich themselves illegally.
