RNG in Action: Seeing Randomness in Everyday Applications

Random number generators – RNGs – are widely used across many different everyday applications, some more obvious than others. While they are commonly associated with the gambling industry due to their usage to ensure fair gaming, they have been used to have an influence across a variety of other tasks, too.

Although there is an element of difficulty in programming a computer to be able to create software that can provide truly random results – as algorithms are often designed to work on patterns that are predictable and have a mathematical methodology behind their workings – the usage of an RNG can help generate unique numbers that do not follow the same approaches.

What are Random Number Generators and how do they work?

What are Random Number Generators

Given the name of the software, it can be quite easy to understand what an RNG is. Indeed, it is software that randomly chooses a number from a set of numbers.

Typically, the number derived from the results will usually be made when two different conditions have been met. These include:

  1. Values being distributed over a defined interval or set in a uniform way
  2. Being impossible to predict what future values may be when based on previous outcomes.

How are RNGs used in everyday activities?

There are some industries and activities that are regularly undertaken that use RNG technology to ensure fairness and results that can help replicate the unpredictability that certain tasks may provide as outcomes.


The gambling industry is often considered to be one of the main adopters of RNGs and is perhaps the most famous, too. This is because the algorithm is used to ensure that there is an element of fairness in the offered games, as it stops them from being rigged in favor of the casino or from players being able to tamper with them.

They can be found in online slot machines, as the algorithm will be used to ensure the results generated are unpredictable and completely random, thus helping them remain a true game of chance.


Aside from its potential value and the volatility that can be experienced, cryptocurrency is known for its enhanced security and the encryption used to ensure its protection. RNGs are used to help make this possible, as the random numbers generated can make it more difficult for the digital tokens to be hacked and stolen.

If they were not truly random, a hacker could potentially find out what the cryptographic key is and then use it to access the account and steal the holding.


Simulations can often use RNG algorithms to make sure various results can be determined. While many will simulate activities because they want to achieve the desired or successful outcomes, the use of random numbers can help them to get a more accurate result.

This is because they can provide unpredictable results that may represent things that could happen as part of their tests. In using an RNG, a company can then look to make better decisions and predictions, as they will have a greater knowledge of what could potentially happen.

Scientific Experiments

Scientific Experiments

Much like in terms of simulations, RNGs can be used to ensure more accurate predictions and decisions are made when conducting scientific experiments. The algorithm can help generate various samples with numerous variables, thus allowing scientists to obtain a bigger picture of the experiment.

This can help them understand what may work and what may not, allowing them to have a greater level of validity regarding their research.

Artificial Intelligence

Given how much it is around us and how impossible it can be not to use it or see it at work, RNGs have been influential on artificial intelligence in various ways.

It has been used to enhance machine learning programs while also having an impact on computer programs. Its use has allowed these programs to obtain more accurate results, thus helping to improve them further.

RNGs are used widely in everyday life

RNGs are used a lot more than you may have initially thought, and their usage clearly has a beneficial outcome.

The randomness that they provide can help to produce a variety of results that may not always be attainable without the technology, thus being advantageous to those who decide to use them.
