What are Casino Random Number Generators (RNGs) & How Do They Work?
If you’ve spent any time playing at an online casino or on a casino floor at a land-based casino, you will certainly have heard the phrase “random number generator”, especially if you play online slots. It’s in every game description and almost every article about any traditional casino game.
In this guide, we’ll break down exactly what random number generation is and how RNG algorithms can guarantee completely random outcomes at the digital table games you play at Stake.
What Is a Random Number Generator?
A random number generator is a software program designed to ensure the fairness of the online games you play at the casino. 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.
Once the shift was made away from the mechanical, one-arm bandit style of classic offline slots to digital, online versions, these physical methods were replaced by computational algorithms. Today, software algorithms are used throughout the industry and scrutinised by regulators to ensure they are true randomness generators 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 Casino Random Number Generators work?
An RNG at a casino works by using sophisticated algorithms that will create a random sequence of numbers that will determine the outcome of a game. What is displayed on your screen is based on the string of numbers the generator has produced.
It is the same as in some video games that use algorithms to decide the outcomes of things like loot boxes and whether you’re one of the lucky winners.
How Are RNGs Calculated?
There are two different types of RNGs; 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.
A digital RNG will run through thousands of numbers in a blink of an eye to generate a completely random sequence that determines the outcome of the virtual casino games you play.
To ensure complete statistical randomness, all RNGs will begin from default generator settings or seeds. In many cases this will be the number 0. This is a critical component to ensure that your next spin isn’t influenced by previous spins and every outcome is completely random.
Are Random Number Generators Fair to Players?
Yes, random number generators are fair. They are used in online slots and digital card games and table games to create fairness and unpredictability. The results of each spin are completely random, with nothing a player can do to influence the outcome. All of our non-dealer games use RNGs for complete transparency and to ensure the game is entirely fair.
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 will pay out more frequently, but they tend to be smaller amounts.
The RTP is the theoretical return a player may expect to receive playing a game over an extended period. The RTP is a percentage of the money bet on a game that will be paid back to players.
Popular RNG Casino Games, Strategies & Tips to Win
There can be no guarantees when it comes to games of chance. There are only tips and tricks to try and give you a better and more memorable experience. These include:
A casino house 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.
