RNG (Random Number Generator) in Online Casinos

Random number generators (RNGs) play a vital role in online casino games as they provide the necessary randomness crucial for chance-based digital games. Reputable gambling sites utilize RNGs that independent authorities have tested to ensure fair gaming at all times.

However, despite these measures, many players still need clarification about the fairness of RNGs. This article aims to shed light on RNGs, exploring their mechanisms and highlighting their significance in online casinos and promoting fair play.

RNG Explained

An RNG is a computer program designed to produce numbers in a truly unpredictable manner. It generates large sequences of independent numbers that lack any discernible pattern. The RNG can provide a single number or a collection of numbers from the generated sequence when prompted.

RNGs come in various types but generally employ one of two methods: "true random" or "pseudo-random."

True Random Number Generators (TRNGs) use physical events with inherent randomnesses, such as noise signals, to generate random numerical values. This ensures that the sequence of numbers cannot be predicted, making it highly secure against potential attacks.

On the other hand, Pseudo-Random Number Generators (PRNGs) use algorithms to generate long strings of numbers based on a shorter seed number. This seed number may sometimes be derived from a physical or natural source, similar to TRNGs. 

However, since PRNGs operate digitally and rely on algorithms and seed numbers, there is a theoretical possibility of a hacker attempting to guess or reverse-engineer the values. Nonetheless, the likelihood of such a breach is extremely low.

RNGs find extensive applications in various domains, such as computer simulations, security systems and statistical sampling. However, in this blog, our focus will be on exploring how RNGs are specifically used in the context of casinos.

How PRNG Works in Online Casinos

Casino sites employ PRNGs to introduce randomness in games without live dealers. These systems serve as automated shufflers for cards and perform basic activities like coin flipping. Behind the scenes, an RNG powers your online roulette picker unless you're playing with a live dealer. 

The PRNG operates continuously, generating numbers that are instantly translated into various game elements. From the symbols on slot reels to the numbered slots on a roulette wheel, the cards dealt in card games or the rolled dice numbers, RNG tools govern these outcomes. Even virtual bingo relies on an RNG for generating results.

RNG Fairness

Legal gambling sites rely on regularly tested RNG software to ensure fairness and trustworthiness. Independent auditors offer comprehensive consulting and testing services for both land-based and online casinos. 

These audits cover a range of crucial areas, such as inspecting RNG systems, evaluating live dealers, sportsbooks and gambling exchanges, assessing game mechanics and mathematics, verifying game payouts and conducting inspections of lottery and pari-mutuel systems. 

By subjecting themselves to these rigorous audits, regulated gambling venues guarantee a fair and enjoyable gaming experience for their patrons.

A certified fair betting site ensures randomness through its RNGs. Players can verify this by checking for the certification seal, usually located at the bottom of the website. Additionally, gambling operators must follow strict protocols and notify regulators before changing machines or games. Violations can result in significant fines or the revocation of their license.

Reputable independent companies like eCOGRA (eCommerce Online Gaming Regulation and Assurance) and TST (Technical Systems Testing) perform regular and thorough RNG checks and evaluations. 

They also conduct live dealer evaluations, security testing, game payout verification and other tests to ensure fairness in online gaming. If you see a seal of approval from eCOGRA or TST at an online casino, you can trust that its games are fair.

Mastering RNG Games: Strategies, Myths and Responsible Gambling

Understanding the random and independent nature of RNG results is crucial for developing a successful playing strategy. It helps players avoid common cognitive biases hindering their performance in casino games. These biases often arise from a lack of understanding of how the games operate.

While casino rituals and superstitions may seem fun, they can lead to irresponsible gambling. Beliefs in hot or cold slots and luck-changing streaks can result in placing large bets on unpredictable outcomes. Falling for misconceptions like the gambler's fallacy reveals insights into player psychology. 

When playing RNG games, it's essential to remember that the results are random and unrelated. Avoid the temptation to continue playing after exhausting your budget in hopes of recovering losses.

To maximize your chances of success, focus on games with low house edges instead of relying on casino myths and rituals. Strategies in games like blackjack can reduce the house edge. Rather than trying to predict random outcomes, employ optimal strategies and choose the right games to outsmart the RNG. Remember, RNGs are continuously active, but setting time and budget limits for responsible gambling is important.

RNG vs RTP

The concepts of RNG and RTP (Return-to-Player) are often confused, but they work together in the world of gambling. RNG generates random number sequences, while RTP measures the percentage of bets that are returned to players as winnings. However, it's important to note that RTP does not guarantee winnings. It simply indicates the likelihood of a game paying out.

In game development, there is a connection between RNG and RTP. When creating a game, the provider establishes the desired RTP range or target before programming the RNG algorithm. 

The RNG software is then configured to ensure that the theoretical RTP aligns with the intended value over a significant number of game rounds (typically over 1,000).
