How Random Number Generators Are Ensuring Casino Games Are Fair

The online gambling industry is built on trust. Players need to know that every spin of the reels, every card dealt, and every game outcome is totally random and fair. Any indication that the house is manipulating results would not only damage the reputation of that individual operator but also of the entire industry.

So, how exactly do online casinos ensure their games are fair? This is where random number generators, or RNGs, step in. This technology, which randomises sequences and guarantees a totally fair outcome, is the backbone of the online casino world.

What is a random number generator?

Random number generators are sophisticated algorithms designed to throw up random sequences of symbols or numbers with no pattern. These are used by online casinos to ensure that the outcome of every game is fair and that neither the player nor the operator can influence the results.

How do I know an RNG is fair?

Of course, every online casino would claim their games use RNGs, so how do we know they are doing it, and how do we know they aren’t being manipulated? Firstly, it is not possible to manipulate an RNG; the random nature of its sequencing guarantees a totally random outcome every time. This can not be manipulated by a casino.

Secondly, if a casino is operating within the UK, it should hold a license from the United Kingdom Gambling Commission (UKGC). It is not possible to be granted a license if you are not using RNGs to determine the outcome of your games, or if you are attempting to manipulate the outcomes of a game in any way.

Finally, there are multiple testing agencies that can verify whether a casino’s games are fair. Agencies like eCOGRA, Gaming Laboratories International (GLI), iTech Labs, and Technical Systems Testing (TST) complete these tests. They run millions of game rounds to verify that the results fall within a statistical range that can not be predicted or manipulated.

If you are a player, you can check for licensing and auditing certificates at the bottom of an operator’s website. UK online casinos should have their licensing and any third-party audit certificates clearly displayed. If you can not find them, we recommend simply going to another online casino that does display them. You should never have to search hard for this information.

Do all online casino games use RNGs?

Online slots, table games, crash games, and other instant-win titles will all use random number generators to determine their outcomes.

Live casino games are different. Some live casinos, such as those with virtual elements or slot-style features, will use random number generators, but other games, such as those using live dealers, will not.

For example, a live roulette game would not need to use a random number generator, as it uses a real-life roulette wheel, which, by design, is totally random.

Where can I find RNG games?

At betting.co.uk, we only recommend top online casinos that are licensed and regulated by the United Kingdom Gambling Commission. As such, you can rest assured that any online casino you find reviewed and recommended on our site will be providing fair, RNG online games.
