Random Number Generators (RNGs) are a fundamental part of online casino gaming. They keep outcomes random, ensuring gameplay remains fair and fun.
RNGs can be found behind the scenes in all online casino games – from table games like Blackjack, Roulette, and Poker, to the likes of online Slots and even Bingo.
No matter what game you choose to play online, you’ll find a Random Number Generator keeping the outcomes unpredictable.
What is an RNG?
An RNG is computer software that generates sequences of numbers or symbols that cannot be predicted or influenced in any way. It is the closest thing to computer-generated randomness we can get – similar to rolling a die or flipping a coin in real life.
With no memory, Random Number Generators can be relied on to ensure there are no patterns or biases in online casino games.
How RNGs came about
Before the development of digital and video Slots in 1976, land-based casino games had little use for RNGs. In fact, the original slot games and fruit machines were activated by the pull of a lever, which would stretch a spring and cause the reels to spin. In land-based Roulette, a professionally trained dealer would spin the wheel to keep the games fair, and likewise with Blackjack, which would also be hosted by a professional dealer.
Eventually, when slot games became digitised and RNGs were introduced to the mechanics, the lever was replaced by a button. These video Slots paved the way for the online casino industry, thanks to the introduction of RNGs.
Keeping table games fair
Without a dealer to keep online table games fair, this job was transferred over to this trustworthy computer software. As mentioned, an RNG has no memory, so no outcome can be purposefully replicated or influenced – ensuring each deal of the cards or spin of the wheel is kept entirely unpredictable.
When it comes to live casino games, a professionally trained dealer will host the game and deal the cards or spin the wheel. This ensures a fair outcome in the traditional manner of land-based casinos, except with the advanced technology that can live stream the games online.
How do RNGs work on slot games?
The digital age has not only meant advancements in the inner workings of casino games, but it has also brought advancements in graphics and mechanics. Because of this, slot games have become more advanced than the standard three-reel fruit machines from back in the day – now featuring a range of themes and symbols that can lead to different outcomes.
Despite this, you can rest assured that RNGs have also advanced, and the software behind each game is set up to enable all possible outcomes, no matter the appearance of the symbols or what they might trigger within gameplay.
—Evidently, Random Number Generators lay the foundations for fun and fair casino gameplay online. And with technology continuing to evolve, it’s likely more game variations will become available to play – each of their foundations resting on chance-based RNGs.
