How RNGs Work for Online Gaming?

A random number generator (RNG) algorithm uses seed phrase to produce random digits or sequences. It is used in video games to predict random events like you hitting a six when you roll a dice.

There are two major types of RNGs. The true random number generators (TRNGs) that use physical processes (like electronic noise) to generate randomness, and pseudo-random number generators (PRNGs) that use algorithms to produce sequences that mimic randomness.

PRNGs can be determined and start from a seed value, which means the same seed will result in the same sequence. TRNGs, on the other hand, derive randomness from unpredictable physical actions.

While random number generators (RNGs), especially pseudo-random number generators (PRNGs), can produce sequences that appear random, they are ultimately deterministic algorithms. This means that if you know the starting point (seed) and the algorithm, you can predict the entire sequence of numbers.

Conversely, true randomness is fundamentally unpredictable and not based on any algorithm or pattern. So, even though RNGs can mimic randomness, they’re not truly random in the same sense as natural, unpredictable processes.

How does RNG work for Video Games?

In online video games, random number generators (RNGs) are used to create randomness in game selections, especially in slots and pokies games.

RNGs are used for generating things like random enemy behavior, item drops, map layouts, and more. Most video games use pseudo-random number generators (PRNGs) because they’re more efficient and provide sequences that appear random.

When a game starts, it initializes the PRNG with a seed value derived from system time or other variables. The PRNG then generates a sequence of numbers based on its algorithm. These numbers determines outcomes such as dice rolls, enemy actions, loot drops, and other random events in the game.

While the generated numbers aren’t truly random, the sequences are often long and complex enough that they effectively create the illusion of randomness for players.

Examples of RNG in Online Pokies Games

RNG’s are commonly used in the online gambling industry, with many providers utilizing the technology for their pokies games. In online pokies games, RNGs ensure fair and unpredictable reel distribution to avoid cheating and manipulation of games.

When a player presses ‘spin’ on an online pokies game, the RNG will determine the outcome of each spin by aligning a random number with a symbol on the game, this will then determine the result of the spin.

We have already identified the two main types of RNG technology that most online casino providers will typically use. These are TRNG (True) and PRNG (Pseudo).

TRNG: A true random number generator is the hardware used to generate random game results. A TRNG will factor in real life scenarios like environmental factors. A TRNG is likely to be used in a game of roulette where the factors of the speed of the roulette wheel and the size of the ball are taken into consideration.

PRNG: A pseudo-random number generator is a software used to generate random results in a game. PRNG is mainly influenced by a ‘seed’. These seeds are often generated by a computer and help produce authentic randomized results based on digital calculations previously inputted. This type of RNG is likely to be used by pokies providers.

The use of RNGs in online pokies games is necessary to make sure a pokie game is fair when spun. Trusted pokies sites undergo rigorous testing and audits to verify the randomness and fairness of their RNG implementations by authorities such as the eCOGRA (eCommerce and Online Gaming Regulation and Assurance). This authority will assess a pokies sites RNG system and make sure they are random and unpredictable and are not tampered with in any way.

Future of RNG in Pokies Games

Random Number Generators (RNGs) are vital in maintaining fairness and unpredictability in online pokies games.

While they’re based on algorithms and not truly random, they create an illusion of randomness by generating sequences that players and game developers find hard to predict.

Looking ahead, the future of RNGs in online pokies holds countless promising possibilities that can elevate the gaming experience in the long run.

Advancements in RNG algorithms could lead to even more robust methods of generating random sequences, leading to the possible adoption of technologies like quantum-based generators.

Transparency and auditability will increase, with platforms undergoing third-party audits to ensure their RNG integrity.

Blockchain could be used to create transparent records of RNG outcomes, enhancing trust between players and online casino companies.

Customizable RNGs might emerge, allowing players to verify or choose seed values for greater assurance. As regulation in online pokies increases, more requirements for RNG usage and auditing could be established.

In essence, the objective remains consistent: RNGs serve to guarantee fair, unpredictable gameplay, and advancements in technology and fair gaming practices will shape their role in the future of online pokies.

When it comes to online casino games like pokies, ensuring transparency is key to avoiding fraudulent activities and scam. True randomness is impossible to achieve but RNGs take it as far as possible helping the online casino industry to be kept in check.


Random Number Generators play a vital role in online gaming, ensuring that games are fair, exciting, and unpredictable. Pseudorandom RNGs, initialized with seed values that are difficult to predict, generate sequences of numbers that are used to determine game outcomes. These RNGs are rigorously tested and audited to maintain trust and compliance within the online gaming industry.

While concerns about predictability and trust exist, the use of RNGs is essential to maintain the integrity of online gaming platforms, ensuring that players can enjoy a genuinely random and exciting gaming experience.
