What is RNG? Random Number Generation Explained

Types of Random Number Generators

Unlike TRNG, PRNG uses mathematical algorithms to generate random results that cannot be influenced by casinos in any way. Online casino software providers use pseudo RNG technology to ensure fair gaming in their products.  

Certified PRNGs are always put through very careful and very rigorous tests by independent auditing firms such as eCOGRA (which we use at Parimatch as well as undergoing testing by Technical Systems Testing).

Examples of Online Casino Games that Incorporate RNGs

When we think of casino games that require a random number generator, we usually think of slots, but did you know that many other kinds of casino games also use RNGs? 

Let’s examine some popular online casino games that use RNGs to produce reliable random results.  

Slots 

Slots are by far the most common of all online casino games produced. They are also the most popular since they are easy to play with a generally shallow learning curve. Slots like Power of the Vikings or The Goonies: Hey You Guys! are great examples of fun slots that use RNGs to ensure the fun remains fair.  

That said, other slots like progressive jackpots depend entirely upon the random and unpredictable results that only a true certified RNG can produce. With the RNG, games like the Parimatch Branded Megaways or Eye Of Horus Megaways Jackpot King would be unable to function and produce massive random jackpot wins.  

Blackjack 

Blackjack is the most popular card game in the world, outranking even poker thanks to its simple gameplay and very low house edge.  

Games like Blackjack Poker & Pairs or Hi Lo Blackjack use RNGs to determine which cards the virtual dealer deals to players and the dealer position. The RNG in virtual blackjack games takes the place of a human dealer in a land-based casino to ensure that every hand dealt is random and entirely fair.  

Roulette 

Roulette is a hugely popular table game using a numbered spinning wheel to generate random results. In brick-and-mortar roulette, a dealer spins the wheel and places a tiny ball on the surface of the wheel as it spins. When the wheel stops spinning, the result is wherever the ball ends up in a numbered pocket.  

While live dealer roulette has become the most popular online, virtual roulette games like Multifire Roulette, which features multipliers and highly volatile bonus games, simply couldn’t exist with RNGs. Random number generators perfectly simulate the true randomness found when a real roulette ball lands in a numbered slot to produce the win.  

Regulation and Certification of RNGs

Several different independent testing agencies are used to certify the fairness of games through rigorous and regular testing. The following lists the main regulators and independent testing agencies used in the online casino industry: 

eCOGRA – Arguably the most well-known independent auditor and regulator within the industry. eCOGRA stands for eCommerce Online Gaming Regulation and Assurance. Not only does eCOGRA test RNGs for compliance, fairness and randomness, but they also look out for you, the player. 

iTech Labs – Another well-respected independent auditor within the iGaming industry that tests RNGs for a wide range of properties, including unpredictability, independence and random results consistency.  

GLI – GLI stands for Gaming Laboratories International and is considered to be one of the largest independent testers and certifiers of RNG software in the world, not just within the casino industry. GLI works with many industry regulators, such as MGA and UKGC, to ensure online casino fair gaming compliance.  

Conclusion

Random Number Generators are vital in ensuring that all non-live casino games are consistently proven fair. It is clear that the presence of RNGs guarantees random results on every spin, deal of the cards, roll of the dice, or every spin of the wheel. 

In addition, RNGs are indispensable in building confidence and trust between players and the casinos that offer these games of chance. 

RNG FAQ

Is it possible to rig RNGs? 

No, not if the online casino in question is a reputable and licensed online casino (licensed through UKGC, for example) and uses certified RNG software. For example, all RNG casino games offered at Parimatch are tested by eCOGRA to ensure fairness and randomness of all games at all times.  

Can RNG software be beaten? 

Certified RNGs are extremely difficult to beat since their ability to produce pure random results on every spin or turn has been independently and expertly tested. RNGs are extremely sophisticated, and regular testing ensures that the RNG always performs according to exact specifications.
