RNG Explained

Here’s all you need to know about RNG in online casinos

RNGs are important in online casinos because they ensure that casino games’ results are random. This article talks about how RNGs work and how important they are for fair play in online casinos.

What Does RNG Mean

The first question you should ask when trying to understand this technology is, “What is RNG?” RNG stands for Random Number Generator. It is a system that generates random outcomes that match a particular system or symbol.

You can also define RNG as a technology that creates multiple strings of numbers every second, and these numbers don’t follow any pattern.

Two types of random number generators are relevant in the online gambling industry. 

  • True Random Number Generators (TRNGs): These generate random numerical values using physical events like noise signals. It is impossible to predict the sequence of numbers, making it difficult for an attacker to compromise the numbers.
  • Pseudo-Random Number Generator (PRNG): These generators use algorithms to build longer sequences based on a small set of numbers. This shorter string of numbers is known as a seed number and is occasionally derived from a physical or natural source. 

Are Random Number Generators Fair? 

Licensed and trustworthy casinos use RNG gaming software that independent auditors like eCogra and Gaming Labs International have tested. These third parties thoroughly check the RNG software employed by these casinos to ensure it is fair. Sites these auditors have vetted bear a seal of approval, usually at the bottom of the page. 

Additionally, gaming operators are prohibited from altering any specific machines or games without going through a rigorous process and informing gambling regulators. A gaming site that violates these regulations will be punished and might have its license revoked. 

How does RNG work? 

How RNGs work
Random triggers ensure the RNG outcome is unpredictable

Random number generators only need an algorithm and a seed number to create outcomes. These results are generated every second, making it difficult to determine the following sequence.

Consider a three-reel slot machine with ten symbols. The RNG would then assign a value to each symbol, then select a random value between 1 and 10 for each spin. This results in three characters being assigned at random and independent of one another.

Why do Casino games use RNG?

Online casinos employ Pseudo Random Number Generators to guarantee virtual game outcomes are entirely random. They can also be used to automatically shuffle playing cards or perform other simple tasks like tossing a coin.

The RNG mechanism employed by casinos is permanently active. This means it generates numbers even when no one is playing the game. The technology is in place to ensure that players enjoy a fair gaming experience.

Which casino games are based on RNG? 

Casino games based on the Random Number Generator are those without a live dealer. Live casino titles don’t need this technology because everything happens in real-time, as in a brick-and-mortar casino. 

Below are details of how NG works in different computer-based online casino games.

What is an RNG Slot?

Random Number generators generate the outcomes of every spin of an online slot game.  

What is RNG Blackjack?

This technology is what determines the value of each blackjack card you and the bot get when playing the game. 

What is RNG Roulette

Unlike live roulette, the roulette wheel is spun by a bot, and the system determines which pocket the ball lands in after a spin.

What is RNG Poker?

Like the RNG blackjack game, this technology determines the card that’ll be dealt when playing poker

What is RNG Keno?

The random number generator is the technology behind the numbers drawn up in a Keno game.  

Final Thoughts on RNG Meaning and How They Work

Random number generators play a massive role in the online gambling industry. This technology runs behind the scenes and determines the outcomes of slots. Game developers also use them to generate results for computer-based versions of table games like roulette and blackjack. 

With RNGs, players can trust that the games in online casinos are not compromised. We have several other aspects of online casinos in our detailed guides for which you need to look out. But as far as fairness is concerned, RNGs have got you covered.
