Random number generators (RNG): What is it about?

In the online gambling industry, fairness and trustworthiness is key. Players need assurance that the games are fair, and that the outcomes are neither rigged nor predictable. To achieve this fairness, online casinos utilize Random Number Generators, or RNGs. This article will describe the crucial role of RNGs in online gambling and how they ensure fairness and reliability.

Understanding random number generators (RNG)

A random number generator is a computer algorithm that produces a sequence of numbers that exhibit no pattern or predictability. These sequences are used in online gambling to randomly determine the outcome of a game – be it the spin of a slot machine, the deal of cards in a poker game, or the spin of a roulette wheel.

There are two types of RNGs: 'true' RNGs that use unpredictable physical phenomena to generate numbers (such as atmospheric noise), and pseudo-random RNGs that use mathematical formulas to produce sequences of numbers that appear random. Online gambling typically uses pseudo-random RNGs due to their reliability and speed.

The importance of RNGs in online gambling

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

RNGs ensure the fairness of games by making sure each outcome is independent and unpredictable. This means that previous results have no bearing on future results, and each player has an equal chance of winning. RNGs also prevent any manipulation of results by the casino or players.

The fairness and reliability of RNGs

For RNGs to be reliable, they must be correctly designed and correctly used. A good RNG will produce sequences of numbers that are uniformly distributed and independent, meaning that each number has an equal chance of appearing as any other, and the probability of each number is not affected by numbers previously generated.

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

RNGs and specific games

The role of RNGs varies slightly depending on the type of online game. For example, in an online slot machine, the RNG determines the outcome of each spin by generating a number that corresponds to each possible position on each reel. In an online card game like poker or blackjack, the RNG is used to shuffle and deal the cards randomly.

Conclusion

Random number generators play a crucial role in the online gambling industry, ensuring the fairness and reliability of games. While their use does present certain challenges, the technologies and regulations in place ensure that players can trust the randomness of online games. By understanding how RNGs work, players can gain a better appreciation of the inner workings of online games and play with confidence.
