Random Number Generators (RNG) are probably the most vital piece of mechanism available in the online gambling industry. We would go as far as to say, that it’s the best piece of mechanism available in your arsenal too.

Without them, online casinos just wouldn’t be fair and would ultimately be rigged at the casinos’ will. When you are playing at a brick and mortar casino, dealers shuffle the cards manually after a specific time, depending on the situation at hand.

When it comes to online, RNGs use a mathematical formula to ensure that every game that you play, the results are produced randomly and impartially. This means that results cannot ultimately be predicted. It is all left to chance.


How do RNGs work?

While land-based casinos use a dealer to shuffle the cards and bingo games shuffle the balls around, the same goes for online casinos, albeit with a more sophisticated mechanism.

RNGs were designed and created with the aim of making shuffling a lot quicker and efficient.

RNG casinos use a system called the Pseudorandom Number Generator (PRNG). This algorithm creates plenty of long strings of random numbers. The entire series of numbers is pre-determined by a fixed number, known as the seed. For example, Uptown Aces uses a Pseudo RNG.

As a result, no one can accuse casinos of rigging their machines or games as it is impossible. Additionally, since software providers need a license to distribute their games, they need to undergo regular reviewing to ensure that the games are fair and impartial.

This is why it is always important that you don’t only sign up to a licensed and reputable online casino, but that you also play games by reputable game providers that tick all the right boxes.


Do all Casino Games use an RNG?

All legitimate and trustworthy online casinos use RNGs, including their games. The only exception to this rule probably applies to live dealer games, such as the ones presented by Evolution Gaming, Net Entertainment and Pragmatic Play.

In the past, RNGs were only used to run online slots and slots machines. These days, online slots are far more complex, and since they can be played over numerous pay lines, an RNG was required to ensure that games were fair. Game of chance sites trust them to produce accurate results, so can you.

When you are playing against a live dealer, shuffling is done in person via live stream. You can see taking place on camera.

RNGs are your safety net. It also derails numerous superstitions and odds. No matter how many times you spin the reels of that slot game, they all have the same odds. It might be important to take a closer look at the Return-To-Player percentage as that would give you a clear indication of how much money you are expected to win over a period of time.

You don’t have to worry about RNGs derailing your strategies. You can still use a bankroll management strategy. You just won’t be able to count cards when it comes to games such as Blackjack, as the RNG reshuffles the cards after each round.
