What Does RNG Mean in Online Slot Machines?

RNG is an acronym for random number generation, which can be called the ‘ brains of slot machines.’ It refers to the use of algorithms to generate random numbers every millisecond. This process continues perpetually even if the machine is not in use, so players can be sure the numbers they see are completely new. It generates a value between zero and four billion.

RNG technologies involve the use of microprocessors that are embedded in remote third-party devices, and once they are developed, they cannot be manipulated.

In this article, I will answer the major question of “What is RNG in slot machines?” and how random number generation works in gambling machines. I will also explain random number generators specifically for online casinos and look at the possibility of hacking casino random number generators.

What is Slot RNG?

Slot RNG

Slot machines have been part of casinos for the longest time and play a big role in the excitement experienced by gamers. The spinning of a reel and the tense moments before the results are displayed is at the core of the game.

The machine’s final graphic display that indicates if you have won or not is determined by RNG. It controls the randomness of any slot machine game and here, we will look at how this mechanism works.

The six key features of RNG are:

  • Use of seed values and mathematical formulas
  • Inability to discern patterns
  • Complete randomness
  • Alignment of numbers to graphic outcomes
  • Continual number generation
  • Allowing for regulatory oversight

Essentially, slot RNG ensures the unpredictability of slot machine games. The outcomes are completely independent of each other, and it’s impossible to predict a pattern. RNG is a fool-proof method to create transparency within slot gaming machines and enhances the level of trust provided to players.

Types of RNG

There are two main types of random number generators, namely

  1. Pseudo-Random Number Generators (PRNGs)
  2. True Random Number Generators (TRNGs)

The table below will outline the characteristics of each.

Comparison Between PRNG and TRNG
PRNG TRNG
An initial seed value is used to produce an algorithm and generate a random sequence of numbers. Unpredictable physical processes are used to produce a random sequence of numbers.
Can produce the same sequence of numbers if provided with the same seed value for reproducibility. Are not capable of producing the same sequence of numbers.
Not ideal for situations where unpredictability and true randomness are required such as cryptography. Ideal for providing true randomness with complete unpredictability to prevent potential hacking.
Commonly used for gaming and simulations. Commonly used for cryptographic applications for secure key generation.
Can be used for applications where an average level of security is sufficient. Used for applications that require high levels of security.
Algorithm could be manipulated externally. Difficult to manipulate or reverse engineer.

RNG for Gambling Machines: Why Is It Necessary?

Any slot machine built after the 1980’s uses RNGs

They serve three main purposes:

  1. Confirming the randomness of slot machines
    Unpredictability is the key feature of slot machines so RNG makes sure players are not able to exploit the system. The use of algorithms generated using mathematical formulas and seed values helps maintain the fairness of slots.
    When a player presses the spin button, this external factor may also affect the initial seed value meaning the unpredictable nature of the game is enhanced.
  2. Dismissing misconceptions about slot machines
    One of the myths surrounding slot machines is that they have a cycle so players can potentially predict when the machine will go through the same sequence.
    However, RNG makes it impossible to predict when the machine will make a winning hit because of its randomness.
  3. Ensuring transparency and adherence to regulations
    All casinos must comply with the rules and regulations of the Gambling Control Board and meet their specified standards. One of the standards they must meet is the use of RNG in slot machines. All machines must be audited and verified to ensure fairness and protect the gaming systems from external manipulation.

RNG and RTP – How Do They Relate?

RNG and RTP are often confused, but they are not the same. RTP, or return to player, is the expected percentage of your bets that a casino game will pay back over time. It does not guarantee a win but works as a prediction of the possible payout.

RNG and RTP, however, work together within the online casino industry, but they refer to two different concepts. RNG refers to the integrity of games, while RTP refers to the effectiveness of the system and how well you can expect a winning outcome.

Both affect your overall gaming experience, and with the right combination of both, you will attract more loyal players who trust your systems. The combination of RNG and RTP is important in providing a secure gaming environment.

Final Thoughts

Digital games, including slot machines, have no precise outcome, and you could potentially lose everything in a few seconds or unexpectedly win big. As the saying goes in gambling. ‘Don’t bet what you can’t afford to lose.’
With this in mind, RNGs are crucial to the maintenance of fairness and integrity in casino games. This article is intended to educate both amateur and experienced players to understand the importance of RNGs and their impact on your gaming experience.

What is RTP in Gambling and How Does it Work?

RTP is a common acronym used in online gambling that stands for Return to Player. This is the average percentage amount a gambler can expect to get back from their bets over the long term.

If you are new to the online gambling business, this is a figure you need to be on the lookout for, as it can influence your winnings.
