If you’ve ever thought about how online casino games like slots or table games manage to stay fair and random, then this is the best place to find your answer. The key to this question is the concept of RNG or Random Number Generator. It’s basically the invisible force behind every spin, shuffle, and card draw in online casinos. After all, what exactly is the RNG, and how does impact your gameplay? This NZ player guide will discuss how RNG works, why it’s crucial for fair gaming, and how it affects your chances of grabbing a positive outcome. However, it doesn’t matter to us if you’re new to online casinos or a seasoned player because understanding the RNG can help you make informed decisions; additionally, you will know what to expect from each game.

Why is it important to understand RNG?
There are a variety of games to check out, all programmed with RNG. Since this affects your playing outcomes, we analysed how this microprocessor works on a wide range of games. If you’re new to online casinos, don’t forget to check our player’s guide where we will introduce you to gambling. By reading this guide you will be able to place the RNG concept thoroughly between other gambling concepts. Moreover, you should learn some tips and tricks about staying safe in online casinos. We identified some essential steps in order to know if the RNG will be rigged or not.
What is RNG?
RNG, or Random Number Generator, refers to a program determining what symbols and cards you will get when wagering on slots and card games. Naturally, live dealer titles do not operate with such technologies.
Can you predict its pick of symbols and jackpots?
Theoretically, yes, but practically, it is impossible for the player. There are two categories of this generator, and neither allows for quick prediction.
The two RNG types
Without further ado, the two categories in aleatory number generation are: 
- PRNG (Pseudorandom Number Generators)
These are the ones which randomise sequences up to a point. Then, the elements will start repeating. Even though this makes it apparently predictable, it takes remarkably long for repetition to occur. Most online casinos use it.
- HRNG (Hard Random Number Generator)
This type ensures entirely random sequencing, and the possibilities are infinite. Most people in the tech and entertainment industries avoid it since it is famously difficult to manage.
Can you trust a Pseudo Number Generator?
Even though it does not contain fully arbitrary sequences, it will take a remarkably long time before the numbers start repeating. In fact, although the combinations are not endless, they tend to reach infinity.
Why are pseudo generators popular in NZ online casinos?
Developers choose these pseudo versions of RNGs because they are accessible. They are much more comfortable to manage than hard number generators. Fun fact: Informaticians have tried to develop randomisers since the late ‘40s. Alan Turing was the first to create a calculator that generated random lines, an HRNG. Later, scientists focused on the easier-to-manage PRNGs.
How does RNG work on slots in NZ casinos
Did you know that 70% of all gambling sites’ income comes from slot plays? Slots are the most frequent pick of NZ gamblers. Thus, we created a step-by-step guide to show you how this system works on them and how this can influence your gameplay. So, if you want to feel, measure, and understand the RNG term better, check the best pokie sites and pick your favourite. Additionally, we recommend checking the bonuses from LeoVegas because with them, you can try many slots, and the boosted deposit will give you more time. Moreover, you can discover how RNG enhances gameplay in the Most Interactive Slots available in NZ casinos. Another interesting fact is to learn the pros and cons of the Autoplay feature and how RNG determines each spin’s result.
Online gambling is safer!
Land-based slots also employ Random Number Generators, but since they are physical machines, they are more susceptible to rigging. Improvements in programming make online slots go through the possible spins more times, which translates to enhanced security. Explore the Best Online Pokies You Can Find in Land-Based Casinos and how RNG affects both.
The system adapts to your playstyle
The bottom line is that your gameplay does not need to change to accommodate the generator. Playing according to a betting strategy will also not help change the outcome – knowing that a website employs RNGs is simply the way to see that you are safe while playing, and all results come from fair gaming.
The hit frequency’s role
This value refers to the rate at which you may land a positive combination. This way, you can appreciate how much of the funds you staked may return to you over time. This hit frequency differs according to the game type: for slots is lower, while for table games is higher. Don’t fall into the trap! It is not clear-cut and still not a way to predict your outcomes. Scoring a jackpot has a 27000 to 1 probability, and the everchanging numbers make it almost impossible to land the pot. Games with higher frequencies will often dish out smaller payouts; jackpots are more likely when you play spins on low hit frequency titles. Tips: Remember that the rate will drop significantly on a progressive jackpot slot.
Is there a tie between RTPs and RNGs?
There is no actual tie between these two, but gaming organisations will generally test both when applying their expertise.
How does RTP & RNG testing go?
After trying a game’s randomiser, the testers will also check its return to player rate, or RTP, for short. Although each game provider chooses the RTP for its products, the institutions must check the integrity of this value.
Card games and live dealer games
Software-based table options also operate on random generators. Whether you prefer online Blackjack casinos, Roulette casinos, Video Poker casinos, or other styles, what matters the most is whether they offer software-based or live dealer products.
RNG is not universal in online casinos!
Naturally, live dealer products have no such system. Instead, the croupier uses multiple decks to randomise the gambling outcomes. Check all the best live dealer casinos in NZ to understand the lack of RNG.
Fairness is still checked and ensured
Even so, software providers for live casino options like Evolution Gaming respond to the same authorities, and their sessions do receive testing for fairness. Although these sessions are different, and none of them is superior, software tables come with more regulations, while live dealer games win in the brick-and-mortar-feel department.
Are RNGs rigged in NZ online casinos?
Rigging is out of the question. When a casino operator wants to make his business legitimate, he must obtain certifications from game testing authorities. They may go for a Random Number Generator certificate or invest in a more encompassing eCOGRA, GLI, or TST approval.
How to check that an NZ casino uses RNG
Checking a casino’s footer is your best option
When you scroll down, you will be able to see core information about the website, including:
- The managing company’s name, along with its serial number and physical address;
- The authority licencing it, including the licence number and registration date;
- The certificate it has (an eCOGRA/GLI/TST/Verisign is preferable to an RNG one);
- An RTP page (if not available in the footer, each game’s paytable must display it);
- The casino’s Alternative Dispute Resolution or the way in which they manage casino disputes.
How to obtain certification
The operator must contact a testing authority or a lawyer who will do so on his behalf. If he asks for an RNG certificate, a testing authority will verify the platform and its games. However, an eCOGRA, GLI, Verisign, or TST certificate is even more valuable – it contains additional, more thorough tests. Furthermore, all these authorities operate in the United Kingdom, complying with the UKGC’s terms. Once an operator receives his documentation, he must publish it on the casino page. Otherwise, he risks fines, and the authorities can take legal action against him. Be aware: If you do not see this information, especially the RNG-related one, check the casino terms and conditions page. If there is no info there either, we advise you to leave the casino and head to a more secure gambling page.
Can RNGs be predicted in NZ online casinos?
Top online casinos in NZ go through testing before establishing a type of RNG. And there are numerous authorities regulating gambling sites’ activities. There’s no real possibility of prediction.
This is not the only value that gets better in online gaming
The most reliable indicator of your outcome, the Return to Player, is also higher than what you’ll find in brick-and-mortar locations.
Why does that matter?
Because you get a clear picture of how the house edge will affect you in the long run. Maintaining a land-based casino costs more than a web version, so the payout gap tends to be higher. And like RNGs, transparent RTPs result from a fully licenced and secure online casino. Tips: Checking out our website will ensure that you only find legitimate gambling businesses, which operate on RNGs.
Are RNGs really random on NZ online casinos?
How do you beat an RNG?
To be more specific, the level of randomness is too high even for a machine to process. As such, it would be impossible to collude with casino play even if you had technology on your side. Especially on slots, the gameplay is left up to chance.
What are the vulnerabilities?
Despite its often-masterful coding, an RNG can crash.
If something like this happens, the UKGC imposes clear regulations
Firstly, operators must report any game whose coding allows excessive winnings or losses beyond or below the designated RTP. Even if they do not have much information on the error, reports are mandatory.
Then, the respective games must be taken down temporarily
Punters should have no more access to a title with a faulty design. The game might go back on the website only after the casino and game testing authorities have finished their investigations.
The unfair results are paid back
The regulatory body UKGC will also ask the operator to determine each player’s excess or insufficient funds affected by the error. As such, you will get your actual payouts at the end of these investigations, whether higher or lower than your erroneous turnover. Important: If you notice that a defective product is still available to play, you may raise the issue with the customer support team. If the result is not satisfactory, you have the option to escalate the complaint to the website’s assigned ADR or report the issue to the UKGC directly. Filling the request form is accessible, and the waiting time will also be on your side; the best reason to contact it, however, is that you’ll receive an objective verdict on your situation.
Final remarks on this software
For a fair gaming experience, RNGs are essential. These algorithms will ensure that you receive a fair outcome – even though the house does famously have an edge, it cannot widen it by ‘rigging’ its available products.
Authorities advocate for it
Authorities like eCOGRA, TST, and GLI make sure of it, as does the strictest commission in the field – the UKGC. Always check the websites’ footers and T&Cs pages to find these institutions’ seals of approval.
Methodology
