What is RNG in iGaming and how does it work?

As many of you are aware, randomness is the fundament of any online casino game. In online games, players depend on luck or the unpredictable nature of chance to determine the course of the game. In this article, TheGamblest will open the brackets and discuss the main character – the Random Number Generator (RNG) in iGaming.

The majority of online casino games employ these RNGs to dictate game outcomes. Esteemed and authorized gambling platforms rely on RNGs that undergo evaluation by impartial bodies, affirming the perpetuation of equitable gaming standards. Despite this, there is a persistent curiosity among players regarding the nature of RNG in iGaming and their authenticity in ensuring fairness.

This article takes an in-depth dive into the concept of RNGs, trying to understand what it is and how it is being utilized in online casinos, and more about RNG Certificate and how you can obtain it.

What is a Random Number Generator (RNG)?

Random Number Generator (also known as RNG) is a computational or physical process designed to create an order of digits that are free from any pattern or predictability. These numbers are often referred to as “random” because they have no discernible order or relationship to each other. RNGs are used in many different fields, encompassing computer science, statistics, cryptography, and of course gambling, whenever a source of randomness and unpredictability is required.

There are two primary categories of random number generators:

1. True Random Number Generator (TRNG)/Hardware Random Number Generator (HRNG): This kind of RNGs are based on physical means, completely hardware-generated, that are inherently not predictable, like atmospheric noise, nuclear decay, Brownian motion, clock drifts, and other quantum phenomena. TRNGs provide a higher degree of randomness as they are based on genuine randomness found in the physical world.
2. Pseudorandom Number Generator (PRNG): This is an algorithm that is fully computer-generated and uses a deterministic process to create sequences of digits of approximate randomness. They start with a starting value called a ‘seed’ and then use algorithms to generate numbers. PRNGs are deterministic, this being said, if you know the ‘seed’ and the algorithm, you will be able to guess the whole sequence. Nevertheless, they can produce sequences that are statistically indistinguishable from true randomness, making them suitable for many applications.

PRNGs are commonly utilized in computer systems, due to their computational effectiveness and ability to produce a large number of seemingly random values quickly. However, for applications where high security is crucial, TRNGs are more preferred.

Keep in mind, that no PRNG can be truly random, as they are fundamentally based on deterministic algorithms. Their results are considered pseudorandom, meaning it behaves like true randomness for most goals, but it is not genuinely random in the way that a TRNG’s output is.

How does RNG work in online casinos?

The concept of RNG in casinos is not novel to the casino world and isn’t exclusive to online gambling platforms either. Even in the era of mechanical slot machines, land-based casinos have long incorporated hardware-based RNGs. These generators are intricately linked to the casino’s server through USB connections. Once this connection is established, the device harnesses intricate values from inherently unstable atmospheric phenomena or physical processes. These initial values then serve as the foundation for generating diverse game outcomes.

In online casinos, PRNGs find applications in virtual games devoid of human dealers or manual intervention. Casino game developers integrate this software into their creations to guarantee the randomness of every iteration. Upon initiating a game on an online casino platform, the generator promptly generates a fresh seed number with each millisecond that passes.

Which casino games use RNG?

RNG is broadly used in almost all online casino games encompassing online slots, virtual poker, bingo, keno, craps, virtual lottery and scratch card games, virtual sports betting, blackjack, roulette, etc.

RNG-certified slots ensure independent and random spins, offering users equal winning opportunities. In online poker, RNGs ensure random card distribution, preventing unfair advantages and external influences. In sports betting, RNG is used in different ways to determine the likelihood of certain sporting events, as well as to determine the outcomes of virtual sports games. This randomness is what creates the element of chance in slot games.

What is RNG certification?

Operators, who are just starting their path in iGaming, should include RNG-related expenses in their budget planning. Let’s see what is it exactly, and why online casinos may need it.

A Random Number Generator Certification vouches for the statistical number randomness generated by computers and machines. It guarantees the absence of patterns in these numbers, confirming their true randomness.

This certificate is validated by an authorized RNG testing organization. It confirms that a gaming machine, online or mobile platform meets the standards. These rules guarantee complete randomness and unpredictability in the generated numbers, making sure fair gameplay for all users and credibility.

How to acquire an RNG certificate?

The process of acquiring an RNG certificate involves a few key steps, whether it is issued by governmental bodies or private organizations. Here is a breakdown of the certification procedure:

Step 1. Select a certifying organization

Initially, you must choose the certifying body that will audit your system and grant you the RNG certificate. During this stage, you will also need to assemble a package of necessary documents. The certification price will be unveiled at this point.

Step 2. Test the system

Once you have all the required documents in place, the testing phase commences. This step involves a thorough evaluation of various components, including:

• Internal state of the RNG
• Game loop integrity
• Unpredictability with no repetitions
• Scaling and shuffling
• Statistical randomness

Any vulnerabilities within the system are typically found and addressed during this phase.

Step 3. Complete diehard testing

RNGs are subjected to rigorous “diehard tests,” that are specifically created to assess the level of randomness in algorithms and are among the most stringent evaluation criteria.

Step 4. Check the Chi-square test compliance

At this juncture, the RNG undergoes scrutiny to ensure it complies with Chi-square tests, further validating its integrity. The entire generator verification process typically spans 1-3 weeks. Some certifying companies may expedite testing by offering a selection of pre-approved algorithms.

Step 5. Include it in your website

Once you’ve obtained the RNG certificate, it is imperative to display it prominently on your gambling website. This action serves to affirm your casino’s commitment to integrity and transparency, and it also plays a crucial role in attracting a fresh and relevant audience to your platform

Why obtaining an RNG certification is beneficial for operators?

Having an RNG certification comes with a number of benefits for casinos, especially for several important reasons:

• Fairness and Integrity: RNGs are crucial in maintaining the equitability and integrity of casino games. They ensure that the outcomes of games are completely random and not influenced by any external factors. This builds trust among players that the casino is operating a legitimate and honest gaming environment.
• Regulatory Compliance: Many jurisdictions and regulatory bodies require casinos to use certified RNGs to ensure compliance with gambling regulations. Having RNG certification demonstrates the casino’s commitment to adhering to legal standards and can help them obtain or maintain their operating licenses.
• Player Trust: Players are more likely to engage with a casino that is transparent about its gaming practices. When a casino prominently displays its RNG certification, players are more likely to trust that the games are not rigged and that they have a fair chance of winning.
