RNG: How it works

Rookie players always wonder how online casino games work. Everyone knows that when you hit the “Spin” or “Deal” button, the system somehow comes up with an outcome. Yet, how these process works are confusing to many people. Well, the secret behind casino game outcomes lies in random number generators, i.e. RNGs. Just like their name suggests, RNGs are programs that generate random results. So, every time there is an outcome, an RNG did its job correctly. Thus, reputable operators like Mr Green Casino, 888 Casino and GoWild Casino use world-class RNGs for their games.

RNG Explained

So, we already mentioned that an RNG is a computer program whose role is to generate random outcomes. Actually, these random outcomes are random sequences of symbols, cards or numbers. The formula behind these outcomes is something called an algorithm. The algorithm comes with a series of instructions for generating the outcomes.

Every sequence of numbers triggers a new sequence of numbers. These outcomes never favour any result over another result. Thus, in case there are two possible outcomes, on the average, both should appear around the same number of times. RNGs, especially those used these days, are highly sophisticated and function impeccably.

Slots-armWhat Casino Games Use RNG?

Now that you know what RNG is and how it works, you must wonder what casino games use this software. In fact, all games at online casinos use RNGs for generating outcomes. Even though the result looks different, the concept works the same. Thus, for online slots, the RNG generates the symbols that land on each of the reels. When it comes to card and dice games, the RNG generates cards or dice rolls. Same goes for video poker games and instant win games like Keno or Lotto. In other words, unless you play live dealer games, all online casino outcomes come from RNGs.

Why Casinos Use RNGs?

Online casinos use RNGs to both guarantee players fair results and to protect themselves. Namely, when an RNG is responsible for the outcome, operators don’t need to worry that someone will trick the system. This way, they know that all the results on their platform are 100% fair and unpredictable. Naturally, by guaranteeing players fair results, they also build their reputation. It goes without saying that players always prefer trusted operators, so using tested RNG works in casinos’ favour.

Are RNG Generated Outcomes Fair?

The most important question regarding RNGs is whether the outcomes are fair. Well, in the past there have been scenarios with rigged results. However, these days the regulations are strict, and RNGs used at top-rated casinos always provide fair outcomes. Fair outcomes are entirely random and unpredictable. Moreover, they include no interference from operators.

Can You Manipulate RNG Outcomes?

Many players wonder if they can manipulate RNG outcomes. Well, the general answer to this question is no. These algorithms and programs are high-tech, and it’s not possible to just trick them. Hundreds of players have tried to figure out how RNGs work. Nonetheless, the only times when people succeeded in this, it was someone who had insider info or software access. Plus, not only RNGs these days are incredibly secure, but they also undergo tests by independent auditors.

RNG Testing Bodies

At the bottom of top-class online casinos, you can often notice the logos of independent auditors. These auditors work independently from operators and test RNGs for them. Once they perform tests that prove an RNG is working correctly, they issue a fairness certificate to the operator.

Usually, they would evaluate the RNG as well as the game and mathematics. Additionally, they perform penetration testing and audit the security of the software. This is what gives operators the right to publish logos of such testing companies on their websites as a fairness guarantee. Regarding testing companies, the most popular ones are eCOGRA, TST and GLI.
