How Online Casinos Ensure Fair Gaming with RNG Technology


RNG Technology – A concern that many players have when they are playing online is that they are somehow being hoodwinked by casinos. However, that is far from the case. All top casinos online will use advanced algorithms known as random number generators, or RNGs, to ensure that every spin of the reels or turn in a card game is totally random. In this guide, we will look at what an RNG is, how casinos use them to keep games fair, and their impact on you as a player. 

What Does an RNG Technology Do? 

The clue to what RNGs do is in their name. They are random generators that ensure that every spin of the reels or every virtual card that is drawn is totally random. These tools are created by computer algorithms that ensure their outcomes are not influenced in any way by external factors. 

Those external factors include the casinos themselves. That’s right, operators have absolutely no idea how a spin will turn out, ensuring that they do not have an unfair disadvantage over their customers. All RNGs are hosted on servers separate from casinos, ensuring that there is no foul play or involvement. 

But what about return-to-player (RTP) rates? These are theoretical rates where players get a certain percentage of their stake back when playing over a period of time. This is all factored into the algorithm that generates the outcome of each spin. This is where the casino has its edge, but it does not mean it has any knowledge of an outcome, with each spin resetting the odds and formulating a new outcome.

Are Games Tested for Fairness? 

So a casino says that the results are generated by using an RNG, but does that mean you have to believe them? It’s a fair question, and a bit of healthy skepticism is encouraged when you’re betting online. 

Firstly, you can breathe easy knowing that any licensed casino is going to be using RNGs to determine the outcome of their games. Operators need their licenses to make money, and if they want to crack the biggest markets, they will need to make sure that they comply with the rules. You should always check the licensing information of a casino before you sign-up and deposit any money. A lack of a license means that you could find yourself in hot water if things go wrong. 

Plenty of independent third parties will monitor the fairness of online casinos and ensure that games are operating as they should. This information is often available at the bottom of the screen when you visit a casino. eCOGRA is one of the most trusted parties, and you will regularly find its seal of approval at top online casinos. 

Does This Impact How I Play? 

One of the biggest myths pedalled by gamblers is that they have some sort of control over the outcome. People will pay attention to the results of previous spins or turns when, in reality, they don’t make any difference whatsoever. 

The idea that you are due a win is one of the biggest misconceptions in the world of gambling. Just because the game has turned five reds in a row on roulette doesn’t mean it has to throw up a black next time. In fact, it could continue to land on red on every spin going forward because each spin resets the odds and is 100% random. Every new spin is its own calculation. 

RNGs ensure 100% fairness, which also means that it ensures you don’t have any sort of advantage over the casinos either. There is zero point in trying to be clever about the next outcome because a totally random algorithm that you or the casino have any influence over will determine it for you. 

As such, make sure you never chase losses when you are playing. It is totally down to the luck of a random computer generator, and you only run the risk of losing more. If someone tells you that they have found a surefire way to win on online slots or card games of chance, then that simply isn’t true. 


RNG Technology – RNGs are one of the most important pieces of technology in the world of online gambling. They ensure 100% fairness on every spin or turn that is taken, and they keep the gameplay exciting. They also mean that you can relax and have fun when you are playing at a casino, safe in the knowledge that there is no foul play going on, and that you will need some luck if you want to land a win.
