What are Random Number Generators (RNGs) & How Do They Work in Games Online?

Online gamers and social casino players have seen the term random number generator (RNG) in many of 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 at online social casinos like Stake.us .

What Is a Random Number Generator?

A random number generator is a software program designed to ensure the fairness of video games and other online 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 scrutinized by regulators to ensure true randomness and prevent random number generator settings from being altered for favorable 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 game development studios .

Are Random Number Generators Fair?

Yes, random number generators are fair. They are used in online slot games 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 produce a win. Games with low volatility will produce wins more frequently, but they tend to be smaller amounts.

High-variance games produce wins less often, but when they do, players are more likely to receive higher amounts. Popular high-volatility games in the Stake.us lobby include  Pragmatic Play ’s Big Bass Bonanza Extreme .

The RTP is the theoretical return a player may expect to receive playing a game over an extended period. Check a game’s RTP in the game rules. The industry average RTP is 96%. However, it can vary between titles, as things like having jackpots attached or feature spin options  can have an impact. Games like Wanted Dead or a Wild from Hacksaw Gaming , Plinko have some of the best RTPs, as well as many other Stake Exclusive games .

RNGs Tips & Strategies to Win

There are no guaranteed strategies for winning online slot games . However, you can apply the following to get the most out of your online social casino experience:

  1. Select games with the highest RTP. Games with the best return-to-player percentage will likely produce more frequent returns.
