How Does RNG Work At US Online Casinos?


Playing at an online casino is a great way to enjoy your favorite casino games without having to leave the comfort of your own home. But how do you know that the games you’re playing are fair? How can you be sure that the results are truly random?

The answer lies in the Random Number Generator or RNG. This is a piece of software that is used to generate random numbers. The RNG is what ensures that all casino games are fair and random. Every time you spin the reels of a slot game or make a bet on a table game, the RNG produces a random number. This number then determines the outcome of your spin or hand.

Online casinos are subject to strict regulation to ensure that their RNGs are fair and random in the US. If you want to learn more about RNGs and how they work, keep reading. We’ll give you all the information you need about RNGs and how they ensure fair gameplay at US online casinos.

What Is An RNG?

A random number generator, often known as an RNG, is computer software that creates numbers at random. RNGs generate huge sequences of numbers that do not follow any order every second. They are accountable for giving a single or a group of numbers from the series when requested. 

There are several different types of RNGs, but most of them employ one of two approaches to produce numbers: “true random” or “pseudo-random.”

True Random Number Generators

As the name suggests, these RNGs use an unpredictable physical process to generate numbers. This can be done in several ways, but one common method is to use electrical noise from devices like amplifiers or microprocessors.

Pseudo-Random Number Generators

These RNGs are not truly random because they use mathematical formulas to produce numbers. However, these formulas are so complex that they produce numbers that appear to be random.

How Does An RNG Work?

Now that you know what an RNG is, you’re probably wondering how it works. As we mentioned earlier, RNGs use either a “true random” or “pseudo-random” approach to generating numbers. True random number generators use an unpredictable physical process to generate numbers, while pseudo-random number generators use mathematical formulas to produce numbers.

Both methods are used to generate numbers that appear to be random. However, true random number generators are more difficult to predict than pseudo-random number generators. This is because pseudo-random number generators use algorithms that can eventually be guessed, while true random number generators do not.

This is why pseudo-random number generators are used in most computer programs, including online casino games.

How Do US Online Casinos Use RNGs?

US online casinos will use a random number generator (RNG) for any online games that do not have actual dealers. Assume you’re playing blackjack, and you decide to hit. The RNG will then select a random card from the deck to give you. 

The process is entirely automated and happens very quickly. The dealer doesn’t even need to be present for the game to work. In fact, most US online casinos don’t even have dealers.

You’ll only see an actual person if you’re playing a live dealer game. Live dealer games are streamed in real-time from a land-based casino or studio. You’ll be able to see the dealer and other players, and you can even chat with them.

Other than that, all other games at a US online casino, like slots and table games, will use an RNG.

Are RNGs Fair?

Yes. Online gambling regulators in the United States and worldwide require that online casinos use fair RNGs. Online casinos are subject to strict regulation to ensure that their RNGs are fair and random in the US. 

If you’re ever worried about the fairness of an RNG, you can always check to see if a reputable gambling commission licenses the casino. Casinos that have these commissions licences are required to use fair RNGs.

Can You Beat A Random Number Generator?

No. It’s impossible to beat a random number generator because, by definition, they are random. Some people may try to tell you that they know how to beat an RNG, but don’t believe them. There is no way to beat an RNG, and anyone who tells you otherwise is lying or doesn’t understand how they work.

The only way to win at an online casino is luck. You can increase your chances of winning by playing games with a higher RTP, but you can never guarantee a win.


RNG technology did not allow online casino gambling to be realized, making casino gaming a more equitable activity. RNGs make it possible for everyone to have an equal chance of winning, regardless of their skill level. This is one of the main reasons why online casinos are so popular. Whether you’re playing slots, blackjack, roulette, or any other game, you can rest assured that the outcome is random and fair.
