Random Number Generators at Online Casinos Explained

By Ryan White Updated: February 2023

Who remembers when the only way to play casino games was in a land-based casino? Most likely, not many. Lasseter's, Australia's first online casino, opened its doors in 1999, and a lot has changed since then. In Australia, there are currently over 25 different online and mobile casinos to choose from. To learn more about how to find your favourite casino, visit the reviews page.

Today, you can play online casinos from the comfort of your own home, or you can play on the go on a variety of mobile casinos. You don't have to be concerned about playing at a casino as long as it has a license. Many casinos offer hundreds, if not thousands, of different games to choose from, with pokies and video poker being the most popular in Australia. To ensure that all casino games are fair, they use a random number generator (RNG). This means that the outcome of each game is completely unpredictable.

​​​​​What is a Random Number Generator?

A random number generator is a piece of computer software that generates the game's outcome at random. There are many different types of RNG, and both online and mobile casinos use a random number generator known as pseudo-random. This RNG is unique in that it does not require any external input (numbers or data) to produce an output. They only require an algorithm and a seed number. New seed numbers are generated on a regular basis, and this is accomplished simply by taking the most recent number or two generated and then performing a mathematical operation (addition, subtraction, multiplication, division, etc.) to generate a new random outcome.

​​​​​Why is gaming online and on mobile fair?

First of all, as long as a casino has a valid license then you can be sure that gaming will be fair. As mentioned above, Australians have more than 25 different casinos to chose from and play any games they like. You never know if you will win when playing because every game has a random number generator that generates the outcome of the game. If you are lucky you can win huge sums and the best thing is that winnings in Australia are tax-free.

​​​​​Do all casinos use a Random Number Generator?

Yes, all licensed casinos are using RNG. Each and every game provider has its own. The exception for a random number provider is when you are playing on a live casino on an online casino or mobile casino. When playing on a live casino you don´t have an RNG. Instead, you have a real dealer that is supervising the game, just like when you are playing on a land-based casino.

​​​​​When does the random number generator decide the outcome?

As soon as you have made your bet and pushed the play or spin button the RNG has already decided the result of the game you are playing. It is important for you to know that each and every game round is random and you can not affect the outcome of the game in any way. It also does not help to play several times to increase your chances of winning.

​How do casinos use a random number generator?

RNGs are not only used on online and mobile casinos. They are also used on land-based casinos and other places where you can for example fins pokies, video poker, virtual roulette, virtual blackjack and more. To understand a little bit better how the RNG works we use pokies as an example. If we for example have a pokie machine with five reels and let us say that there are 12 symbols per reel. The random number generator will come up with 1 – 12 for each of the reels. The result would be 5 different symbols. And if those 5 symbols would make a winning combination you win. How much you win depends on the value of the symbols.

​​Trustworthy Testing companies for RNG

Technical Systems Testing (TST) and eCOGRA are two third-part auditors that perform regular checkups to make sure that the RNG is correct. They are considered to be reliable. They both check RNG on online casino as well as on land-based casinos. For players, this means that they can be sure that they are playing in a fair casino.

What Factors Influence the Fairness of Online Casino Games?

Even though you have many different fair casinos to choose from it is still hard to find the best casino that gives you the best value for your money. Most casinos in Australia offer their players welcome bonuses when they register as a new player at the casino and some are offering free chips or free spins. Some casinos also offer players a so-called no deposit bonus. This is a bonus you get without making a deposit to your casino account. Most casinos allow their players to play any casino games they want with their bonus but an exception is often on live casinos.

One casino that we recommend that has a fair bonus for new players is Ozwin casino. This casino offers new players a very lucrative bonus of 200% up to $ 2000 on both your first and second deposit into your casino account. In addition to bonus money, you also get 50 free spins on both your first and your second deposit. To take advantage of this offer, you must use Ozwin's bonus codes.
