Online gambling has undergone a substantial evolution since its genesis in the 1990s, with the advancements in technology making it viable to relish a diverse selection of games from the comfort of one’s abode. As the populace continues to gravitate towards iGaming, one term that frequently arises is RNG, or Random Number Generator. In this exposition, we shall delve into the intricacies of RNG, how it functions, and its significance in the realm of online gambling.

  1. Introduction

Players engaging in online gambling yearn for an equitable and lucid gaming experience. This is where the Random Number Generator (RNG) enters the picture. RNG is the bedrock of online gambling, ensuring that games remain truly random and that the casino does not manipulate the outcome in its favor. In this paper, we shall expound on RNG and its role in iGaming.

  1. What is RNG?

A Random Number Generator, commonly abbreviated as RNG, is a computer program that generates a sequence of numbers or symbols in a random sequence. In online gambling, RNG is leveraged to determine the outcome of a game, such as which cards are dealt or which symbols appear on a slot machine. The use of RNG guarantees that the outcome of every game is genuinely random and fair, providing all players with an equitable chance of winning.

  1. How does RNG work?

RNG employs intricate algorithms to generate a sequence of numbers or symbols. These algorithms are designed to be entirely random, lacking any evident pattern or predictability. The numbers generated by the RNG are then used to determine the game’s outcome, such as which card is dealt or which symbol emerges on the slot machine.

  1. The Significance of RNG Certification in Online Gaming

Online gaming’s popularity has soared, with an amplified demand for just and secure gameplay. RNGs play a vital part in ensuring the fairness of online games, providing an unpredictable outcome. In this write-up, we shall scrutinize why RNG algorithms were adopted as the foundation of online gaming and how to obtain RNG certificates from credible testing labs.

Why were RNG Algorithms Chosen as the Foundation?

RNG algorithms were adopted as the foundation of online gaming because they provide absolute fairness without manipulating the game’s outcome. In other words, it is impossible to circumvent an RNG algorithm. Although various RNGs exist, the fundamental mechanism is devised to ensure that chance is the only element that can influence the game’s outcome.

Acquiring RNG Certifications from Esteemed Testing Laboratories

In order to maintain the veracity of the RNG algorithm and conform to regulatory standards, online gaming operators must obtain RNG certificates from renowned testing laboratories. Presented below are some of the most distinguished testing labs in the industry:

BMM Testlabs

BMM Testlabs is an established independent laboratory that has been scrutinizing and attesting to the authenticity of games for over three decades. BMM Testlabs’ team possesses the skill to scrutinize any gaming content for RNG compliance, regardless of the jurisdiction chosen by the operators. BMM employs a two-pronged strategy to implement iGaming brand verification, including preliminary content confirmation and quarterly verification. The certification process necessitates technical audits performed by BMM experts, followed by a panel decision on whether to issue a certificate of conformity.

iTech Labs

iTech Labs is another world leader in testing and certifying online gaming systems, operating since 2004. iTech Labs now offers accreditation in Europe, Asia, and the Americas. iTech Labs concentrates on the regulations and limitations of particular jurisdictions to ensure that their clients’ game content aligns with existing licensing requirements. The RNG certification process from iTech Labs consists of three stages, including code analysis and vulnerability testing, followed by a sequence of diehard tests that demonstrate the system in action.

Gaming Labs International (GLI)

Gaming Labs International (GLI) is a prominent iGaming test lab that authenticates RNG-based games. GLI certificates are universally recognized across regulated markets, rendering them highly coveted for iGaming brands. The certification process entails a general overview of the RNG code, followed by a series of diehard battery of tests and outcome distribution tests.


eCogra, a regulatory and assurance agency headquartered in London, conducts comprehensive inspections of online gambling software and systems. The primary objective of the organization is to safeguard player rights, ensure fairness in games, and guarantee provider responsibility. The technical experts at eCogra meticulously examine and assess if the games offered comply with the requirements of RNG (Random Number Generator) and are functioning optimally. A positive evaluation of the audit results in an extensive report and eCogra certificate.

The significance of RNG certification in online gaming cannot be emphasized enough. RNG algorithms are indispensable in ensuring that online games are unbiased and unpredictable, providing players with a sense of security and confidence in the games they play. To ensure the integrity of the RNG algorithm, online gaming operators must obtain RNG certificates from trustworthy testing labs. Reputable testing labs, such as iTech Labs, BMM Testlabs, Gaming Labs International (GLI), and eCogra, are some of the options available to online gaming operators for RNG certification.

There are two primary types of RNGs utilized in online gambling – hardware-based and software-based. Hardware-based RNGs employ physical devices, such as radioactive decay or atmospheric noise, to generate random numbers. In contrast, software-based RNGs use computer algorithms to generate random numbers.

Another potential disadvantage is ensuring the quality of the system. There are various RNG algorithms, each with varying degrees of reliability and accuracy. Moreover, errors in coding or implementing the RNG system could lead to inaccuracies and biases.

Furthermore, developing and maintaining RNG systems could prove to be quite expensive. The algorithms utilized in these systems must be frequently updated and tested to ensure their security and reliability. Smaller online casinos might find this a cumbersome and costly process.

Finally, RNG systems may seem less transparent than traditional casino games. This lack of transparency could lead to players mistrusting the randomness of the game’s outcome and assuming it to be influenced by the casino. Online casinos must be transparent in their use of RNG systems, providing players with clear and concise information regarding their functioning.

Although RNGs are a vital component of online gambling, it is essential to consider the potential drawbacks and undertake proper measures to mitigate any risks.

Testing and Certification of RNG

Testing and certifying Random Number Generators (RNGs) is a crucial factor in ensuring the transparency and fairness of online gambling. Numerous organizations and regulatory bodies are responsible for testing and certifying these systems.

One such organization is eCOGRA (eCommerce Online Gaming Regulation and Assurance), an independent testing agency specializing in certifying online gaming software and systems. RNG systems undergo their scrutiny to ensure that they provide a truly random and unbiased outcome for every game.

Several regulatory bodies oversee online gambling and require RNG certification. Some of these bodies include the Malta Gaming Authority, the UK Gambling Commission, and the New Jersey Division of Gaming Enforcement. These regulatory bodies mandate online casinos to obtain RNG certification from approved testing agencies before obtaining a license to operate.

To ensure the fairness and transparency of online gambling, specialized software is used to test and certify Random Number Generator (RNG) systems. Millions of tests are conducted to generate statistical data on the randomness of the system, which experts analyze to ensure the system’s unbiased and truly random nature. The certification of an RNG system is performed regularly to maintain the system’s transparency and fairness over time, enabling players to trust the outcomes of their games and have an equal chance of winning.

Transparency and fairness are critical in the iGaming industry, and RNGs play a significant role in ensuring both. Online casinos should provide information on the type of RNG used and the certification process, enabling players to make informed decisions about which games to play based on the game’s rules and payout rates.

As technology continues to advance, we can expect to see even more sophisticated RNG systems in online gambling, incorporating advanced encryption and blockchain technology to offer greater security and fairness.

RNGs are essential in various industries, including online gaming, cryptography, and simulations. There are two main types of RNGs: Hardware Random Number Generators (HRNGs) or True Random Number Generators (TRNGs), and Pseudo Random Number Generators (PRNGs).

HRNGs or TRNGs are physical devices that generate randomness through mechanical processes, accounting for environmental indicators such as atmospheric pressure or air temperature to produce a genuinely random result. PRNGs, on the other hand, are software algorithms that produce a random number sequence through a seed value or condition, which does not require external influence to generate a result.

Forecasting PRNG Results

Pseudo-Random Number Generators (PRNGs) utilize a seed number and a mathematical algorithm to produce random results. Although it is theoretically possible to forecast the outcomes by knowing both the seed number and the algorithm, it is practically unachievable, and the results are still considered random.

There are two primary types of Random Number Generators (RNGs): Hardware-based RNGs (HRNGs) and Software-based RNGs (PRNGs). While HRNGs produce randomness through a physical device, PRNGs use a software algorithm and a seed number.

Both types of RNGs create random results, but PRNG outcomes can potentially be predicted if you know the seed number and the mathematical principle. Understanding the functionality of RNGs is crucial for individuals who work with cryptography, online gaming, or simulations, and selecting the appropriate RNG for your application is essential.
