Random number generator: how a random number generator (RNG) works in a casino
Randomness is the basis of gambling. Players rely on randomness, also known as random, or chance.
Ideally, everything depends on how a card or chip lies in the game. Traditional land-based casinos, on the other hand, have never been known for their 100 percent honesty. For example, there are formulas that can calculate quite accurately the probability that a game will end, but that’s a problem.
Online gambling is another problem. The latest technology can fulfill players’ needs for reliability.
Players want to trust their games and establishments. When they start playing, they want to think that they have a chance to win and that nothing unknown will happen. The random number generation algorithm ensures that the results in online games are transparent and unbiased. A system that guarantees fair play is truly revolutionary.

How does the random number generator (RNG) function?
As you may have guessed, the term “random number generator” or “random number generation” stands for “random number generator” in the gambling industry. A RNG is the same algorithm that creates a sequence of random numbers when it comes to online casino games.
How are slot machines and random numbers related? It’s pretty obvious. In online gambling, random numbers are used to determine the outcome of each round of the game, as well as which symbols will fall on the reel of the slot machine.
Categories of games: random number generators (RNGs) and live dealer games In the gaming industry, an RNG is more than just a basic algorithm for generating random numbers for games, usually slots. Broadly speaking, the term “HGC games” refers to all games of chance. In contrast, live dealer games, in which randomness does not depend on software, are an alternative.
Live dealer games recreate the unique atmosphere of a land-based casino, as well as the human connection.
A live dealer game is essentially an online experience in which the player deals cards, rolls dice, and spins the roulette wheel.
In general, playing with a live dealer is similar to playing in a real establishment. This is because it has the same atmosphere, and the outcome of the round depends on how the dealers shuffle the cards or spin the roulette wheel.
Slot machines are the most common example of slot machines in casinos. An algorithm creates a sequence of images that appear on the reels of a slot machine when a player presses a button. These images determine whether or not the player wins. In addition, there are other categories of games such as fishing, table games, video poker and casual games that utilize the HGC algorithm and do not require human interaction.
The main difference between them is their mechanics. Live dealer games rely more on human interaction, whereas HCS-based games rely more on algorithms. However, both types of games utilize technology.
Random number generator (RNG) games use a vector of random numbers.
The use of GSCs in the Internet gambling industry
Game providers utilize GSC algorithms. At all costs, game content developers must guarantee full transparency of their products. Their main goal is to prove that the game is completely unbiased.
Essentially, a GSC is an algorithm built into a game that is hosted along with the game files on a remote game server, which may belong to the game provider or a third party. This being the case, it is impossible to influence the GSC at an online casino.
Gaming Simulation (GCS) technology is used to create game content and determine the winner of a jackpot campaign. For example, a jackpot aggregator is a multi-functional marketing tool that actively utilizes GCS tools in its processes. The HSA increases the trust of players and operators, ensuring perfect honesty and reliability regardless of the type of jackpot.
The principle of operation of the HSCG and PRNG:
A hardware random number generator (HRG) is a generator of truly random numbers, whereas a pseudo-random number generator (PRNG) is a generator of pseudo-random numbers.
Although the two work with the same goal of producing a sequence of random numbers, their approaches are quite different.
A physical device called an AGSC can generate random numbers during a mechanical process. To create an unpredictable result, the physical device typically takes into account several environmental factors. Air temperature, the amplitude of atmospheric pressure over a period of time, or the number of times a player presses buttons are examples of such indicators. The device takes measurements, translates these measurements into values and gives a final result. Such values are unpredictable, so the result is random.

The PRNG algorithm is programmed to create a sequence of random numbers using a specific value or condition known as an “initial value”. The algorithm requires no external influence to produce the result; all that is needed is the algorithm itself and the initial value. The range of possible results the generator can produce is determined by the key of the initial value. This is the first value added by the hashing algorithm to its equations. Although the PRNG uses numbers, the outcome of a game is almost never expressed in numbers. For example, in slot machines, there is a tile with an image corresponding to each value, and this tile determines which round will start on the player’s screen. Thus, here we discuss a certain possibility of predicting the results of the PRNG. If you know the initial value and the calculation principle, you can theoretically determine the combination of conditional “cherries and lemons” that the slot machine algorithm will produce. However, in real life this is unlikely.
Certification of HSC-based games: HSC evaluation ensures that the game operates fairly. Players who want to be sure that they invest their money in a reliable casino with games from an official provider, most often apply for such certificates.
As a result, HCS plays an important role in online gambling, helping operators and game providers to implement a strategy of “provable fairness”. In short, “provable fairness” is a method of verifying and confirming that certain online gambling establishments are trustworthy to their audience.
Why was the GSC algorithm chosen as the basis? Simply put, it is impossible to beat the random number generator in a casino. The types of GSC and how they work vary, but in general, this mechanism helps to guarantee the complete fairness of games without affecting the outcome. Nothing but luck can affect the outcome.
Let’s take a look at who and how they issue HGF certificates:
BMM Testlabs is an independent laboratory specializing in game testing and certification. With over thirty years of experience, it is one of the most respected experts in gaming content. Regardless of the jurisdiction chosen by operators, the BMM team can verify that game content is compliant with the iGC. BMM utilizes two stages of iGaming brand verification. First, there is a preliminary content verification, which includes GST, mathematical consistency, functionality, etc. As for the certificate itself, the commission decides to issue it after a number of technical audits by BMM specialists.
Since 2004 iTech Labs has been one of the world leaders in testing and certification of online gaming systems. iTech Labs is currently accredited in Europe, Asia and America. The brand closely monitors the laws and regulations in place in certain jurisdictions to ensure that customers’ gaming content complies with current licensing requirements. HGC certification from iTech Labs consists of three steps. The team first checks the code for vulnerabilities. The next two stages of testing include a set of robustness tests that verify how well the system works.
Gaming Labs International (GLI) is another well-known iGaming testing lab that certifies HGC-based games. GLI certifications are very popular among iGaming brands because of their international endorsement. Although there are many variables, the process of validating GSC algorithms basically consists of the following steps:
Gambling System Code Overview Gambling System Code Set of stability tests Result distribution tests eCOGRA is a London-based organization that oversees online gambling software and systems. Protecting players’ rights, ensuring fair play, and holding providers accountable are the main goals of the organization. Technical experts conduct a thorough analysis to find out whether the games offered are compliant with the HGC requirements and work properly. A detailed report and eCOGRA certificate is issued after a positive audit.
The difference between GStream and RTP is that these terms are often confused.
As stated earlier, GSC is an algorithm capable of generating infinite sequences of random numbers. The percentage of bets returned to the player as winnings is called Return-to-Player (RTP). Although winnings are not guaranteed, RTP is simply an estimate of how much the probability of payouts is for each game.
There has been a relationship between GSC and RTP since the development of the game. The provider determines the RTP range or target of the game before proceeding to program the GSC algorithm. The GSC software must then be customized so that the expected theoretical RTP matches the target RTP over 1,000+ game rounds.
Although both concepts are used simultaneously, they are used for different purposes. The GSC ensures player safety and casino integrity, while the RTP shows how successful the operator is in utilizing this strategy.
Trust the math: online gambling depends on random numbers. Since the dealer executes part of the code, players can’t see him shuffle cards or roll dice.
It doesn’t matter what type of DST a brand relies on, what matters is that with this algorithm, operators can add fair and safe games with unpredictable results to their portfolio. This makes HSCs the gold standard in iGaming.
