What does a Random Number Generator do?

A random number generator (sometimes referred to as RNG) is a program that machines use to create a number that looks random. Computers are incapable of creating truly random numbers. This is because computers can only do what they are programmed to do, they cannot create or invent anything and so they are incapable of ever creating anything truly random.

What is a Pseudo-Random Number Generator?

A pseudo-random number generator creates numbers that appear random to an observer. If a generated number cannot be predicted by a user before it is created, then it is considered to be as good as a truly random number. There have been many different methods of creating random numbers that vary in complexity depending on a particular program’s requirements. Some count the number of milliseconds that have passed since the program has started then apply a predetermined mathematical formula to this value to create a new number. Others track things like the input from a user and use this as the basis. These algorithms are known as pseudorandom number generators.

The key when creating a pseudo-random number generator is coming up with a system that is too complex to reverse engineer. If a random number generator becomes predictable after repeated usage, then it can be exploited. This must be avoided at all costs in online casinos. Games that can be exploited by players are bad for casinos and games that do not offer a fair chance to win are bad for players. The only solution is to use a pseudo-random number generator that creates results that are completely unpredictable.

How do Casinos Ensure Random Results?

All reputable online casinos must submit their games for evaluation and testing by accredited third party regulators. These tests evaluate the pseudo-random number generators, game mechanic and underlying mathematical evaluations, the reliability of live dealer games or sportsbooks, lottery systems, poker systems, security audits and more. Casinos that pass these tests receive certification stating their legitimacy.

This certification means that players know that the games they play are fair and meet with regulatory requirements such as average payback percentages. The rules vary depending on where the casino is based, even if it is digital and can be checked with the bodies who grant certification which must be listed on the casino’s website.

While it is theoretically possible to hack a digital casino or figure out its RNG system, this is practically impossible. Casinos monitor their users for suspicious activity and there are plenty of security measures in place to make sure everything is kept fair. Casinos are also incapable of altering their games after they receive certification. Random checks are performed to ensure that there has been no tampering.

Some people may worry that developers of casino games leave backdoors that allow them to exploit the systems for themselves. This does not happen. It is simply not possible to leave exploits of this nature in a game and have it pass third party certification requirements. Outside checks and balances keep everything fair for casinos and players alike.
