🎰 What RNG is and How it Works?

Random Number Generator, or RNG for short, is a vital component of the online gaming industry. It is a software program that produces a sequence of numbers or symbols that have no pattern, making them unpredictable and random. In iGaming, RNGs are used to determine the outcomes of various games such as slots, roulette, blackjack, and others.

The RNG ensures that the results of the games are random and fair, which is crucial for the integrity and trustworthiness of the online gaming industry.


The use of RNGs is also a regulatory requirement in many jurisdictions to ensure that players are not being cheated or scammed.

RNGs work by utilizing complex mathematical algorithms to generate a sequence of random numbers. These algorithms are designed to produce numbers that are statistically random and unpredictable. In the case of online gaming, the RNG produces a sequence of numbers that determine the outcome of the game.
The process of generating these numbers is completely automated and occurs within milliseconds.

The RNG software uses a seed number, which is a starting point for the algorithm, to produce a long sequence of numbers. The seed number is usually generated by taking a snapshot of the current time on the computer or some other form of unpredictable data.

Once the sequence of numbers is generated, they are used to determine the outcome of the game.

For example, in the case of a slot machine, the sequence of numbers is used to determine which symbols appear on the reels. In the case of a card game, the sequence of numbers is used to determine which cards are dealt to the players.

Since the RNG is generating random numbers at such a fast rate, it is virtually impossible for anyone to predict the outcome of the game, making it fair for all players.

🔢 Types of RNG

Two main types of RNGs are commonly used in iGaming: hardware RNGs and software RNGs.

  • Hardware RNGs use physical devices, such as radioactive decay or thermal noise, to generate random numbers. These types of RNGs are considered to be the most secure and reliable, as they produce truly random results that cannot be predicted or influenced. However, they are also more expensive and complex to implement than software RNGs.

  • Software RNGs, on the other hand, use mathematical algorithms to generate random numbers. These types of RNGs are less expensive and easier to implement than hardware RNGs, but they are also considered to be less secure, as they rely on the complexity of the algorithm to produce unpredictable results.

Within the category of software RNGs, there are two subtypes: Pseudo-Random Number Generators (PRNGs) and True Random Number Generators (TRNGs).

  • PRNGs use a mathematical formula to generate a sequence of numbers that appear to be random, but are actually deterministic. This means that if the same seed number is used to generate the sequence, the output will be the same every time. While PRNGs are not as secure as TRNGs, they are still widely used in online gaming due to their ease of implementation.

  • TRNGs, on the other hand, use physical processes, such as atmospheric noise or electrical noise, to generate truly random numbers. Since these processes are inherently unpredictable, the numbers generated by TRNGs are truly random and cannot be predicted or influenced. However, TRNGs are more complex and expensive to implement than PRNGs.

⚖️ Why is RNG important in iGaming?

RNGs are essential in iGaming to ensure the fairness of the games. In traditional land-based casinos, the randomness of games is ensured by physical mechanisms such as the spin of a roulette wheel or the shuffle of a deck of cards. However, in the online gaming industry, where players cannot physically see the games being played, it is critical to use RNGs to ensure that the outcomes of the games are fair and random.

By using RNGs, online gaming operators can provide players with the same level of confidence in the fairness of the games as traditional casinos. The use of RNGs ensures that the outcomes of the games are not manipulated or predetermined in any way, giving players an equal chance of winning. This level of fairness is crucial for the integrity of the online gaming industry and ensures that players can trust the games they are playing.
