In the past decade or so, the gaming world has seen a revolution thanks to online casino games. Web-based platforms that allow people to gamble have existed for a lot longer than a decade, in fact. But they’ve seen massive growth in recent years. 

With this popularity, the technology behind such websites has also grown. One tech advancement that ensures fair play is Random Number Generators. These are essential to offer a random experience no matter how many times you spin the reels or draw a card. Randomness is the underlying requirement of every online game, especially one involving real money. 

Understanding the Random Number Generator

An RNG is a piece of software that generates random numbers or outcomes. In gambling, it produces the results of the games you play, like the symbols on a slot machine or the cards in blackjack. These numbers are random and unpredictable, ensuring fair play. When a button is pressed, the software runs through all possible outcomes and randomly stops at one. When it works as it should, it’s impossible to predict the outcome. Because of it, it’s very difficult to beat the system when playing games of chance. Without this tech, slots machines and other titles wouldn’t work like they ought to. All reliable online platforms, like Grand Mondial, Zodiac, Classic, Yukon Gold and Luxury Casino, use random number generators.

The History of RNG

In the past, slot machines used mechanical systems to determine the outcome of each spin. There were gears at work that spun the physical reels when a lever was pulled. This lever would slowly go back to its original position, at which point the gears stopped and you got your reels. Today, modern slots use computerized RNGs, in which software algorithms create even more random results. These are not mechanical but essentially work the same way as the original system. The first computerized slot machine was created in the 1970s, and RNGs have been used in online gambling since the 1990s.

The Role of Random Number Generators in Online Casinos

All reputable online casinos use RNGs to ensure fair play. This algorithm is implemented in all classic casino games, meaning the provider guarantees fair results. The use of RNGs means that the outcome of each game is independent of previous games, and there is no way to predict the next result. You’ll see this system in action at Casino Classic games where random number generation ensures a thrilling experience. All the top-quality casino sites utilize technologies like this so players enjoy their time without worrying about getting scammed.

RNG Auditors

To ensure the fairness of RNGs, auditors like eCOGRA are responsible for auditing and certifying online casinos. It’s their job to find out if a site delivers everything it promises. As a part of this, they test the RNGs to ensure they’re truly random and that the casino is not tampering with the results. Other than this, auditors also perform the following checks: 

  • Game and mathematics analysis
  • Payout verification 
  • Lottery inspections
  • Evaluation of live dealers and sportsbooks.

Online platforms, such as Casino Classic, proudly display the eCOGRA badge, as that means they are audited and approved. This adds another layer of trustworthiness to gambling sites and assures users that they don’t need to worry about their chosen platform’s intent.

A Chance to Beat the Algorithm

It’s impossible to predict the outcome of a game using an RNG. Trying to cheat the system is also very difficult because of the sophisticated algorithms. They are designed to produce results that are nearly impossible to predict or manipulate. 

That’s not to say that the system cannot be tampered with though. If someone hacks into the software, they change how the algorithm works to benefit themselves. However, this would require highly in-depth knowledge and understanding of coding, not to mention skills to get into a secure system. For the everyday gambler, there’s practically no chance to beat the software. At the same time the top-tier online casinos, like Classic Casino, Ruby Fortune, Quatro, Katsubet, and other well-known Canadian gambling platforms, provide the highest level of security preventing any attacks and data leakage.

RNG Based on Blockchain

It’s true that RNGs have added a lot of security to slot machines and other games. This technology changed casino platforms for the better. However, it is made much more secure and trustworthy with the use of blockchain technology. This enhances the transparency and fairness associated with RNGs. 

By using a decentralized ledger, it’s possible to prove that an RNG is actually random and hasn’t been tampered with. Blockchain-based RNGs provide players with even more confidence in the fairness of online gambling. The software for regular RNGs is created by the casino operator or is at least controlled by them. A decentralized RNG, on the other hand, isn’t. It’s not solely controlled by any one party so the chances for cheating are minimized as much as possible. It is also harder to hack and offers significantly more transparency. 


Online gaming for money has come a long way. With it, tech has also advanced to provide users with the best possible experience. RNGs are critical in every online casino for ensuring fair play on gaming platforms. They’re the part that leads to random results, no matter which virtual game you’re playing. Reputable organizations are tasked with auditing this technology to ensure fairness. As safe as they are right now, the blockchain is poised to make them even more secure. So, the next time you’re gambling at a reputable casino, know that there’s an RNG behind the table and slot games to generate random numbers.
