# Random Number Generator (RNG): what is it?

A Random Number Generator (RNG) is a computer algorithm that generates a sequence of random numbers without any predictable patterns. In online casinos, RNGs are used to determine the outcomes of games of chance, such as the spin of a slot machine, the dealing of cards in poker, or the result of a roulette spin. This ensures that each outcome is completely independent and unpredictable, which is essential for guaranteeing fair and reliable gameplay in an online environment.

## Types of RNGs

There are two types of Random Number Generators (RNG): "real" RNGs that use unpredictable physical phenomena to generate the random numbers (such as atmospheric noise), and pseudo-random RNGs that use mathematical formulas to generate random numbers. Online gambling usually uses pseudo-random RNGs because of their reliability and speed.

## The importance of a Random Number Generator (RNG) at online casinos

In a land-based casino, randomness is guaranteed by physical factors: the way dice are rolled, the speed of the roulette wheel, the way cards are shuffled. In an online environment, where these physical factors are absent, RNGs are essential to ensure this randomness.

RNGs ensure that casino games are fair by ensuring that each outcome is independent and unpredictable. This means that previous results do not affect future results, and each player thus has an equal chance of winning. RNGs also prevent manipulation of results by the casino or players.

## The fairness and reliability of RNGs

To be reliable, RNGs must be designed correctly and used correctly. A good random number generator will produce sets of numbers that are evenly distributed and independent, meaning that each number has as much chance of appearing as any other number, and the probability of each number is not affected by previously generated numbers.

To ensure the fairness and reliability of RNGs, online casinos undergo regular audits by independent bodies. These bodies test RNGs to ensure that they actually produce random and fair results.

## RNGs and specific games

"Now where is this used in an online casino?" is among the frequently asked questions. The role of RNGs varies somewhat depending on the type of online game. For example, in online casino dice slots, the Random Number Generator determines the outcome of each spin by generating a random number corresponding to every possible position on each reel. In an online card game such as poker or blackjack, random numbers are also used to randomly shuffle and deal cards. The only place in an online casino where RNGs are not active is at a Live Casino, because the randomness is physically created there.

## Conclusion

We can say that a number generator plays a crucial role at online casinos. It ensures the fairness and reliability of the games. Although its use presents certain challenges, technologies and regulations ensure that players can trust the randomness of online games on our platform. By understanding how RNGs work, players can gain a better understanding of the inner workings of online games and play with confidence.
