What are Casino Random Number Generators (RNGs) & How Do They Work?
Casino players have heard the term random number generator (RNG) bandied about many times in the description of the games they play. But what does this mean? How exactly does RNG technology work? And can it be trusted to produce fair outcomes?
RNG is an algorithm that produces a random sequence of numbers which cannot be predicted. RNGs are at the core of online slot games and virtual table games, providing the excitement that makes them so entertaining to play.
In this article, we explain everything you need to know about RNG software and how it’s used in online casinos.
What Is a Random Number Generator?
A random number generator is a software program designed to ensure the fairness of casino games. The RNG generates a sequence of random integers that determine the outcome of each spin of the reels, turn of the card or roulette wheel spin.
Random number generation in slots can be traced back to the days of mechanical slot machines that used physical mechanisms like levers to generate random outcomes.
These mechanisms were used to recreate the default random outcomes of roulette wheels and such; however, these methods proved problematic as external factors like general wear and tear could impact results.
As technology improved, mechanical randomness generators made way for computational methods, and a new world of electronic RNGs arose. Today, software algorithms are used throughout the industry and scrutinised by regulators to ensure true randomness and prevent random number generator settings from being altered for favourable results. This is why all our Stake Originals titles have provable fairness.
How Do RNGs work?
There are two different types of generators; the first is ‘true random number generators’ that use physical phenomena to create random numbers, and the second is ‘pseudo-random number generators’ that use mathematical formulae.
Computational algorithms generate thousands of random numbers per second, and the player hitting the spin button determines which is used for the outcome. This random number algorithm is designed to ensure that the results of each spin are random.
The importance of RNG in modern casinos is evidenced by the sheer volume of staff with mathematical backgrounds employed by development studios.
Are Random Number Generators Fair?
Yes, random number generators are fair. They are used in online slots to create fairness and unpredictability. The results of each spin are completely random, with nothing a player can do to influence the outcome.
Understanding Game Volatility & RTPs
Volatility in slots refers to the risk involved in playing a game by measuring how often and how much a game will pay out. Games with low volatility, such as NetEnt’s popular gem-themedStarburst, will pay out more frequently, but they tend to be smaller amounts.
There are no guaranteed strategies for winning online slot games. However, you can apply the following to get the most out of your online casino experience:
Select games with the highest RTP. Games with the best return-to-player percentage will likely produce more frequent returns.
Check a game’s volatility and pick one that suits your gambling style.
Set yourself a budget and stick to it.
Take advantage of our bonuses and promotions to maximise your wins.
Only play for fun – online gambling should be an entertaining experience.
What is the difference between the house edge and the odds of a bet?
A casinohouse edge is its advantage over the player, calculated as a percentage of your bet the casino expects to keep over an extended period.
The odds of a game refer to the likelihood of a particular outcome and are more likely seen in dice or card games or when wagering on sporting events where the odds are calculated based on the previous performance of an athlete or team.
