A Random Number Generator (RNG) creates random numbers, and online casinos use it to run many games. It’s designed with various factors to ensure true randomness. This design ensures players get a fair game and prevents casinos from manipulating results.

## Concept of Random Number Generators

The concept of Number Generators can be observed by rolling a die. Most dies have six faces. A single die can generate numbers between 1 and 6. With the help of probability, one can predict the outcome of every roll of a die, and this is because the likelihood of rolling, say, a five on a die is one-sixth (⅙). That is, there is a 16.67% chance of moving a 5.

With Random Number Generators, though, the number generation scope is much broader. True Random Number Generators can produce a vast sequence of digits that do not follow a specific pattern. In essence, you cannot easily predict the outcomes from an RNG.

## Types of Random Number Generators

There are two major types of Random Number Generators: True random number generators and Pseudo-Random Number Generators.

**True Random Number Generators (TRNGs)** get their values from physical elements such as resistor noise, keystroke timing, or mouse movement. These events are random and, therefore, can be used to generate random numbers.

Hackers will have a hard time predicting numbers generated using this method — because of the nature of events that supply the numbers. Although secure, TRNGs are expensive and can be hard to implement.

**Pseudo-random number Generators (PRNGs)**, on the other hand, use algorithms to generate random numbers. PRNGs achieve this by capitalizing on small strings of numbers (called seed numbers) to create random numbers.

Seed numbers can be from sources such as TRNGs and natural sources. The sequence of numbers generated using this method is deterministic, meaning it is possible to predict PRNG-generated numbers if the initial seed number is known. However, such a fit takes a lot of work to attain.

## How Random Number Generators Work

As previously mentioned, True Random Number Generators(TRNGs) derive numbers from physical events. For instance, They can generate random numbers based on the precise time from a clock, measured in milliseconds. Another source of random numbers comes from measuring radiation using a Geiger-Müller counter.

However, this method of gathering random numbers has its drawbacks. Each randomly generated sequence requires external hardware to collect data, resulting in a time-consuming process that lacks speed.

In contrast, Pseudo-Random Number Generators employ a different approach. The term “pseudo” (meaning false) indicates that the digits generated using this method are not genuinely random but only appear to be so.

Let’s delve into one of the many ways for generating Pseudo-Random Numbers. The method is known as the Linear Congruential Method (LCG). This algorithm relies on four inputs:

- A modulus number
- A multiplier number
- An increment number
- An initial seed number obtained from the real-world

You input these values into the formula: Pseudo-Random Number = (Seed number × multiplier number + increment number) mod (modulus number).

The result is a Pseudo-Random Number, which is fed back into the formula to generate the following sequence of Pseudo-Random Numbers.

For instance, consider generating a series of Pseudo-Random Numbers with the following values for our seed, multiplier, increment, and modulus: 3846, 324, 6257, and 9726. Plugging these values into the formula, we obtain the first pseudorandom number: 7433.

This number is then used in the same formula to generate a sequence of pseudorandom numbers: 2501, 9323, 2123, and so on. These calculations are performed on computers, making this method highly efficient and speedy.

There are slight caveats with this method. While the results may appear random, they are not truly random. The digits from a pseudorandom number Generator occur in cycles. After a point, the whole sequence starts again from the beginning, the seed number.

## Random Number Generators and Online Casinos

The nature of games offered by Casinos requires Random Number Generators, which is why casinos capitalize on Pseudo-Random Number Generators in their games. These PRNGs serve as a backbone to many Online Casino games.

In roulette, an RNG determines the slot the ball falls to. In slot machines, each symbol is assigned a variable. An RNG determines what variables to display, providing users with complete fairness.

When it comes to poker, an RNG is employed to shuffle cards. And if you are a fan of online bingo, an RNG usually selects your bingo numbers. Other games that require flipping coins and rolling dies — like crap — capitalize on Random Numbers.

Because of the high dependence on random number generators, you may wonder if it is possible to outsmart RNGs at a Casino. **While it is possible, beating a Random Number Generator is almost impossible**. There is hardly a record of anyone who succeeded.

## Are Random Number Generators always fair?

To a high degree, yes. Legal and reputable Casinos regularly test their RNGs to ensure players have a fair and enjoyable experience.

Players can verify if their Casino of choice is certified by organizations such as the **eCOGRA (e-commerce Online Gaming Regulation and Assurance)**. When betting sites get accredited by such organizations, you can rest assured that their Random Number Generators are genuinely random.

Regulators like this inspect their RNGs to ensure they work correctly and generate random numbers. The auditors will check for flaws and ensure that machines are not rigid.

Auditors also verify game payouts to ensure that players are paid fairly and that the Casino is not withholding any winnings. The auditors will check the Casino’s records to ensure all payouts are made correctly.

More so, gambling operators are prohibited from altering their machines without following a detailed procedure set aside by regulators. If caught, a defaulter will suffer significantly in the form of restrictions and revocation of their license. Rocketpot casino games all comply with the highest gambling standards.
