Scientifically Proving How RNG Makes Gambling Fair on the Internet
Have you ever stopped to think about how your online casino slot outcome is determined?
In a nutshell, all casino games and outcomes are 100% fair, every game is independently tested by accredited industry regulators that oversee iGaming integrity.
So, for every spin you make or every card you are dealt for that betting round, the outcomes are fair and unbiased. These outcomes are fair thanks to Random Number Generator (RNG) technology, which is widely used in minimum deposit casinos. In this guide, we explore what RNG is, how it works, the scientific principles behind RNG, and some common myths and misconceptions about it.
Understanding Random Number Generators (RNG)
Let’s say you have a jar full of cookies, some of which are choc chips, mint creams, and vanilla wafers. If you reach in without looking, whatever cookie you choose will be done randomly. If your friend picks their own cookie, they will probably get a different one. That is how RNG works, like picking random cookies – it’s unpredictable, and the outcomes are unbiased.
What is RNG?
A Random Number Generator (RNG) is a computational or physical device designed to generate a sequence of symbols and numbers that lack any predictable outcome or pattern, thus producing a random outcome. RNG systems can be hardware-based, which uses physical processes to generate random outcomes, or software-based, which uses mathematical algorithms to produce pseudorandom numbers.
Mechanics of RNG
RNG software operates by using a seed and an algorithm to produce random sequences that are fair and unbiased. The seed is generally derived from a very unpredictable source, such as the micro-movements of a mouse or atmospheric noise. The algorithm is often a complex mathematical formula which generates a number that becomes the new seed in a continuous loop, which produces a new set of numbers every time the algorithm is run.
Using RNG for online gambling
For online gambling, particularly in online casinos, RNG is essential to ensure that all game outcomes are random and fair. The RNG algorithm produces random outcomes for each round and spin.
Types of RNG: True RNG (TRNG) & Pseudo RNG (PRNG)
There are two broad types of RNG, and while both methods use different inputs and strategies, they share the same goal – to produce a sequence of random numbers. TRNG uses physical hardware which generates random outcomes through a mechanical process. While PRNG is a software algorithm programmed to produce a random number sequence through a set condition of values, known as a ‘seed’. We will discuss the scientific principles behind RNG later in this page.
How RNG Ensures Fairness in Online Gambling
RNG plays a crucial role in online casinos. When you play online slot games, RNGs are used to determine the position of the reels after every spin. This includes when and where the reel will stop and the combinations of symbols displayed across the paylines. These then determine whether the spin is a winning one or a loss. The RNG ensures that every spin for slot games is independent, unbiased and fair, with no influence from previous spins.
When you play table games such as baccarat and roulette, RNG replicates the random outcomes you would find at physical casinos. For example, when you play roulette, the RNG determines where the roulette ball will land on the roulette wheel. When you play card games like blackjack and poker, RNG shuffles the cards from the virtual decks. Thus ensuring the card distribution is fair and unbiased.
RNG software must be regularly tested by accredited regulators for third-party audits to verify the RNG fairness. If this is not done, the gambling regulators and boards will not process an online casino license. Some top industry regulators overseeing RNG integrity include iTech Labs, BMM Testlabs, Gaming Labs International and eCOGRA.
Scientific Principles Behind RNG
Let’s say you and your sibling are playing cards, and after shuffling, you pick the tenth card at the top of the deck without looking, and you get a King. Now, if your sibling does the same process and, after shuffling, picks the tenth card without looking, they get a Five. This shows you that while you did the same process, you each got different outcomes, similar to how RNG works – it’s fair and random!
Okay, back to the scientific principles behind RNG; as mentioned earlier, there are two types of RNG, and below is an overview of how both work:
TRNG
True RNG is a piece of physical hardware which generates random outcomes through a mechanical process. The physical device used with TRNG accounts for environmental indicators that produce unexpected outcomes.
For example, these indicators can include air temperature or the number of button presses made by a player over a set duration. With TRNG, the algorithm takes measures, which are then converted into values, which produce the final random output. You can run this algorithm millions of times, and the end values will differ for each outcome; hence, the results are purely random.
PRNG
Pseudo RNG is a software algorithm programmed to produce a random number sequence which is determined through a set condition or value, which is generally referred to as a ‘seed’. PRNG does not need any external influences to produce a result; only the algorithm and seed are required.
The seed determines the range of possible outcomes that the generator can produce. The seed is the first value that the algorithm uses for the mathematical equation to determine the outcome and result.
Testing and Certification of RNG in Online Gambling
All online casinos require RNG certification before going live, and this testing should continue annually. RNG certification is a process through which an independent body (such as iTech Labs, BMM Testlabs, Gaming Labs International and eCOGRA) examines the RNG used by the online casino to ensure it generates truly random outcomes and results.
RNG testing includes statistical testing (assesses the randomness against statistical norms), source code analysis (examines RNG algorithm for any potential bias) and output analysis (extensive testing of generated sequences to ensure they don’t follow a predictable pattern).
These tests carried out by independent bodies are crucial for all online casinos. If these tests show that the RNG is not fair and outcomes are not randomized, then international government regulators/ gambling boards such as the UK Gambling Commission and Malta Gaming Authority can revoke online casino licenses.
Common Myths and Misconceptions About RNG
Player perception of fairness may differ from statistical reality, especially when players lose. However, there are several myths and misconceptions surrounding RNG, and before we can share these, we want to reiterate that RNG is fair and all outcomes are random, so there is no rigging or cheating at any low deposit casinos or at the top rated online casinos.
Below are some common myths and misconceptions about RNG:
- RNGs can be manipulated by online casinos
- All licensed and regulated online casinos that operate under strict regulations ensure certified independent bodies regularly test all RNG. Thus ensuring fairness and ensuring that online casinos cannot manipulate these RNGs.
- RNGs can be predicted over time
- Despite PRNG using a set algorithm, these complex algorithms and the use of unpredictable seeds ensure that outcomes can never be predicted over time. All RNG outcomes are always random and fair.
- Hot and cold streaks
- This is a common misconception by online casino players. If you are on a winning run, you think you are due a losing run soon, or if you are on a cold streak, you expect your next win to be around the corner. In reality, all RNG outcomes are random and fair, so predicting any hot or cold streaks is impossible.
The Future of RNG in Online Gambling
As technology advances, we will see even more advanced RNG algorithms and more stringent testing from independent bodies. History has shown this is already occurring based on the advancements in quantum RNG, blockchain-based fairness verification and AI and machine learning RNG systems.
One thing is certain, though: with the advancement of technology, the fairness of online gambling and online casinos will continue to be 100% trusted, and all outcomes will be random, thanks to RNG.
