Everything You Need to Know About Online Casino RNGs

Randomness is at the heart of both online and land-based gambling. Before the inception of online gaming, dice rolls and roulette spins were all governed by luck. However, certain formulas were known to predict the outcome of dice rolls with greater accuracy, and this was an issue. In online gaming, this is not the case thanks to Random Number Generators (RNGs).

Online casino RNG is a computer program that generates random numbers every second. These values are independent and don’t follow a certain pattern or sequence. The generated numbers can then be used to determine the position of the ball in roulette or a symbol in online slots. Read on as we uncover everything you need to know about Random Number Generators (RNGs)

How online casino RNG works

In an online casino setting, there are two types of RNGs: pseudo-random number generators and true random number generators. Pseudo-RNG produces random numbers that rely on an algorithm, which is a set of instructions. These numbers are not truly random but just approximate with pseudorandomness.

After the numbers have been generated, probability theory is used to calculate the likelihood of different game outcomes. For instance, in roulette, the probability of landing on a certain colour can be calculated based on the number of winning outcomes. Software providers design and develop virtual casino games and ensure that they comply with industry standards. With these standards in place, players can enjoy fair games and also be certain of the encryption of both personal and financial information.

Auditing and certification

RNG audits are crucial to ensure that games are incorruptible and provide fair winning chances. For players who want to enjoy gaming at trustworthy casinos, there should be certifications from independent auditors. These audits verify that the RNGs are truly random and unbiased to ensure the integrity of online casino games.

There are different types of certifications and agencies that provide their services to online casinos. They include eCOGRA, GLI and iTech Labs, among others. The primary task for these companies is to conduct thorough testing of RNGs and their outcome to ensure compliance with industry standards. Players can check if an online casino is certified by looking at the badge or logo on their website. This badge is an assurance that the casino has undergone independent testing by a reputable agency.

Gaming regulations

Several regulatory bodies are responsible for ensuring player safety and fairness in online casinos. They include the United Kingdom Gambling Commission (UKGC), the Malta Gaming Authority (MGA) and Alderney Gambling Control Commission (AGCC), just to name a few. These bodies enforce strict regulations and gaming practices to protect players from fraudulent activities.

Their primary task is to monitor the operations of an online casino to determine if they have fair RNGs, player protection mechanisms, responsible gaming, and secure payment methods. To find a regulated and licensed casino, players should check the logos on the casino’s homepage. Verified online casinos will include badges from the licensing bodies. Alternatively, they can visit one of the regulators’ websites for a full list of approved gaming sites.

House edge, variance, and RTP

In online casino gaming, the concept of variance, house edge and Return to Player (RTP) are essential to understand. House edge is the statistical merit that a casino has over players in specific games. It represents the percentage that a player is expected to win in the long run. The higher the house edge, the lower the chances of winning the game.

Variance is the risk involved when playing an online casino game. A high variance indicates a higher risk of losing with the potential of high returns. Games with low variance have a low risk of losing, but the payouts are smaller.

Return to Player, or RTP, refers to the percentage of the total money wagered that will be paid back to the players over time. This is mostly associated with online slots and the higher the RTP, the better the chances of landing a win.

When choosing an online casino game, players should look for low house edge, low variance and high RTP to boost their winning chances. Moreover, each game has distinct features, and this also affects the overall outcome of the game.

Gaming strategies and betting systems

To boost their chances of winning, players usually implement popular gaming strategies or betting systems. However, it is crucial to note that they do not guarantee wins in online games, but rather help improve winning probability. Some of the most used strategies include the Martingale system, the Paroli system and the D’Alembert system, among others. Each of these systems uses different approaches to help players manage their bets.

Bankroll management is another gaming strategy that players use and includes setting a budget for each betting session and sticking to it. This will ensure that you do not wager more than you can afford to lose. To effectively use a strategy, players should understand the rules of the game and the best system to use. They can start with small bets and gradually increase as they get comfortable with the strategy.


Random Number Generators (RNGs) have revolutionised the online gaming industry. They ensure an unbiased and fair gaming environment that is based on luck. Audits by well-known agencies further cement the safety of online casinos by vetting the generators.

To get a better chance of winning in this environment, players should understand the concept of the house edge, variance and RTP (Return To Player). This will help them to choose games with a better probability of success. With all these factors in mind, players can enjoy a fair, safe and potentially lucrative online gambling experience.
