The Mystery Behind Random Number Generators and Their Role in Online Casinos

Nowadays, the demand for online casino entertainment is growing rapidly, and in response to this, the number of different gambling platforms is overgrowing every day. Opening a Google search, you can find many online casinos for all tastes, with credit card payments, as well as visit a Flexepin casino, Bitcoin casino, Ethereum casino, and many others. 

Online gambling has become so popular that hardly any avid player has not yet tried this type of entertainment. Many punters prefer such online casino gaming platforms because they offer many benefits that contribute significantly to a satisfying gambling experience.

Thanks to modern technology, players can enjoy casino classics without leaving their homes. What’s more, you can even play casino games on your smartphone or tablet whenever and wherever you want.

However, the success of online casinos would not be possible without a Random Number Generator. Various casino websites can have an impeccable reputation for being honest and reliable because they use RNG technology. Thanks to the Random Number Generator, the outcome of the games that online casinos provide cannot be predetermined because they are entirely generated by random chance.

The RNG Basics

A random number generator is a sophisticated computer program responsible for randomly generating numbers. Some basic game actions, such as shuffling cards or flipping a coin, can be virtually simulated with this system. This program uses an algorithm to successfully generate numbers, meaning it follows a set of rules that make it possible to produce numbers.

Several types of RNGs are used in the world of technology. For example, online casinos use what is known as a pseudo-random number generator, which works according to an algorithm and an initial number. What sets this system apart from the other types is that it does not require any external data to operate. In addition, the PRNG is constantly active, which means it continually produces numbers that are instantly converted into different elements – card, symbol, or dice.

This continuous process of number generation follows the plan according to which the outcome of virtual games is determined. New numbers are generated by using previously available numbers. To do this, the system performs an essential mathematical operation, which changes each time.

It is worth noting that the RNG is used in all games with a virtual nature. Consequently, not only do online casinos use this technology, but many land-based casinos also offer games featuring this system, such as video poker or slot machines. Such games are developed in the same way, and they are almost identical in this aspect to their online counterparts.

How the Random Number Generator Works

The random number generator produces a series of numbers that do not follow any pattern. For example, every time you play European Roulette, it will generate a number from 1 to 37, whereas in single-deck games, such as Blackjack, the number that will be generated ranges from 1 to 52. In addition, each number generated by the system must correspond to a particular element, respectively, a number on the wheel or a specific card.

In this sense, contrary to the popular belief that the RNG shuffles the cards, it generates numbers that correspond to a particular card. The process becomes more complicated when RNG works with card games that include multiple sets because they contain more numbers. However, this computer system follows a specific algorithm whereby it cannot fail to match the numbers generated with the cards that correspond to them.

All numbers that are produced virtually are generated regularly. Moreover, the actual process of generating continues, even when no one is playing. For example, in dice games, two numbers must be produced at once each time since the game involves two dice. As each dice has six sides, the number that RNG has to create will be from 1 to 6. Whatever number is randomly chosen during the game, it will appear directly on one side of the virtual dice.

Legitimacy and Regulation of the RNG

When we talk about the random number generator, at some point, the question of its fairness and legitimacy inevitably arises. However, even though its basic principle is complicated enough to generate a series of random numbers, there is a guarantee that the result of online games will be fair as well. First of all, you should know that a third-party testing authority entirely regulates all leading online casinos. That means that the RNG used by a particular online casino is regularly tested since this technology is responsible for creating game results.

Several independent companies specialize in testing casino games. Their main priority is to help regulate the online gambling industry and ensure that all available online casino games are truly random and fair. One such company famous for conducting accurate RNG testing evaluations is Technical Systems Testing (TST.) It also conducts actual dealer evaluations, poker system audits, penetration testing, game payout testing, and other similar tests.

You can easily recognize online casinos with online games that successfully meet fairness and randomness requirements because they receive a special certificate. Playing at online casinos with such a certificate is secure. After all, they are considered reliable and trustworthy because they have proven that the outcome of their games is completely random, and any external factors, such as the amount you bet, have no effect on the game outcome.

eCommerce Online Gaming Rules and Assurance is another independent testing company specializing in certifying games and evaluating random number generators. It is an approved testing agency that performs system analysis to determine the fairness of online games. For this purpose, they use live game data for a certain period, which the online casino operator must provide. They test the RNG used in various games such as Blackjack, video poker, roulette, and others. In addition to RNG evaluations, the company also conducts payout reviews that determine how efficient and fast payouts are.

The Vital Connection Between RNG and RTP

Return to Player is your key to finding out a slot game’s RTP percentage after a certain number of spins. Slot RTP has a significant relationship to RNG technology, as the latter uses high technology to create random number chains and achieve slot RTP consistency.

The math behind this system divides a game’s total payout by its absolute increase in turnover. The higher the RTP, the better your chances of winning. The average RTP in slot machines is 96%.

Game providers know that RTP is important for players. Therefore, some of them display the RTP percentage for each slot on the casino site to gain players’ trust.

Which Casino Games use Random Number Generator?

Except for live dealer games, all available casino games can be played online powered by RNG. Live dealer games are very similar to those offered in land-based casinos, as they are hosted by real dealers controlling the gameplay in real-time.
