This article explains the role of Random Number Generators (RNGs) in online slot machines and explains how RNG works in slots technology and slot machine fairness in a simple, understandable, and transparent way.
Many players hear the term RNG, or RNG slots, but don’t actually know what it means and this article will demystify the technology behind online slots and explain why regulated Random Number Generator slot systems are designed to ensure slot machine fairness and unpredictability.
For new players who may distrust online casinos, understanding RNG will go a long way in how they approach their iGaming experiences.
What is RNG in Online Slots?
RNG is an acronym for Random Number Generator. An RNG is a computer program algorithm that generates random numbers. This factor is a vital aspect of all online casino games and is required for regulatory compliance and fairness certification.
The correct use of an RNG ensures that each spin is totally random and unbiased, giving every player an equal chance of winning based purely on the rules of the slot game they are playing.
Each spin, therefore, is an independent event, unaffected by previous outcomes or external factors.
What is an RNG All About?
To put it simply, RNG prevents manipulation and ensures unpredictability.
Random Number Generator algorithms ensure the fairness of each game and guarantee that it is unbiased. Every time a player hits the spin button, the RNG generates a random number that decides which symbols appear on the reels.
How Does RNG Fit into Other Slot Mechanics?
A slot game’s theme captures a player’s attention through emotion, but it’s the technical foundation that ensures fairness and keeps players engaged over time.
Behind every spin is a carefully engineered and thoroughly tested framework.
Premium providers such as Endorphina establish each game’s core mechanics such as RTP (Return to Player), volatility (referring to how often a game pays out and how large those wins tend to be over time), RNG, the number of reels, rows, paylines, and possible winning combinations; and also bonus features.
All these elements are designed to function together as part of a balanced, coherent system rather than as isolated components.
The RNG factor ensures that the golden rule of fairness is achieved with every spin.
How Does RNG Work in Slots?
RNG generates a sequence of random numbers that determines the final positions of the symbols on the reels - even when a slot game isn’t in play. The RNG ensures that each spin is an independent event with entirely random outcomes.
RNG runs continuously, not only when the player clicks spin, ensuring that every spin is completely standalone. This means that previous spins do not affect future results as nothing is based on any built-in patterns.
How Does an RNG Ensure Fairness?
The clue is in the name. The system’s random number generation is completely independent each time and must adapt for the rules of each individual slot game, and this is checked legally by strict market jurisdictions.
Online slot game providers such as Endorphina are required to have their RNGs tested and certified by independent test laboratories to ensure they meet strict standards for fairness and randomness.
What is RNG Similar to in Other Games?
To put it simply, it’s ‘chance’. For common ‘offline’ examples of RNG, think of rolling dice, or shuffling cards. Each roll and shuffle will be completely different each time and where the dice lands or which card comes out on top is totally random and down to the mathematical possibilities of each round.
For example, there are 6 variations with dice, and 52 with cards, and then the multitude of potential outcomes depending on how many dice are rolled or how many cards are dealt in the game.
What is the Difference Between RNG and RTP?
While RNG is a computer algorithm that generates random numbers. Return to Player (RTP) is the percentage of all wagered money that a game is designed to pay back to players over time.
For example, a game with 96% RTP is theoretically designed to return €96 for every €100 wagered over time.
It’s important to note that ‘over time’ in RTP is calculated over a very large number of spins. It does not reflect short-term results, where outcomes can vary greatly.
While RTP is a vital part of each slot game, it is not related to, influences, or is influenced by RNG in any technical way and both are totally independent elements.
The Importance of Certification and Testing Laboratories
Online casino jurisdiction regulations can be some of the strictest in the business world, and the legality is determined by each country or region’s strict regulatory laws.
These regulatory bodies conduct regular inspections and audits with premium online slot providers such as Endorphina to ensure that online slot games operate within approved legal guidelines, and that each slot game produced is as technically reliable and trustworthy as possible.
This means that players can rest assured that these slots are fair and the chances of winning are not influenced by any other factors.
All officially licensed online casinos, operators and game providers should have clear messaging letting potential players, and partners, know that they have been fully vetted for their particular market.
Why It’s Important to Understand RNG
In short, understanding RNG will make a difference to how players should approach each game. This knowledge will also ‘bust’ online slot myths and misunderstandings about probability and how slot technology works.
Common examples would be that:
1. "A slot is due to pay out after a certain number of losing spins, and a win is “coming soon”.
No. Each spin is completely independent and determined by a random number generator (RNG). There’s no ‘system’ where a specific number of past results influences future outcomes.
2. Casinos can modify games in real-time (players playing simultaneously) to make players lose.
No. Licensed games are legally tested and regulated. Outcomes are determined by fully certified RNG systems and are not influenced by individual operators during gameplay.
3. Some machines are ‘hot’ or ‘cold’ and certain games can be on a winning or losing streak.
No. In properly regulated online gaming, outcomes are random and not influenced by previous results. RNG ensures that each spin is independent and randomly determined.
The key thing to take away is that RNG prevents manipulation and ensures unpredictability. Thanks to the RNG, each spin is a unique experience and guarantees that every spin holds the potential for excitement.
Simply remember that slots are for enjoyment and entertainment and are not prediction-based systems.
