All about Random Number Generators RNGs and its use cases
If you are a tech nerd, then you might have heard about Random.org or software that generates random numbers? Random numbers are incredibly useful in a number of ways.
For example, when you need to generate data encryption keys, simulate and model complex phenomena or to select numbers from larger data sets.
They are also used aesthetically in music and literature. One of the most popular modern uses of random numbers for games and gambling.
With the advances in technology. Software programmers found the need for introducing randomness in computer programs. Computers work with directions and logic and it is tough to get a computer to do any task by chance.
There are two popular ways of generating random numbers using a computer – Pseudo Random Number Generators (PRNGs) and True Random Number Generators (TRNGs).
Both these have different characteristics and pros/cons. Let's take a look at each in detail:
PRNGs are algorithms that use math formulae or pre-calculated tables to generate sequences of numbers that appear random.
One example of this is the linear congruential technique. Much research has been done on pseudo random number theory. As a result, modern PRNGs are so good that the numbers look as though they were really random.
The primary difference between PRNGs and TRNGs is somewhat similar to the analogy of the rolls of a dice. PRNGs create the randomness using mathematical formulae or lists, it is somewhat similar to a person rolling a die several times and noting down the results.
When the next die roll happens. You get the next on the list. While the numbers appear random, they are somewhat predetermined.
However, True Random Number Generators or TRNGs work by actually getting a program to roll the die (as it were).
Some characteristics of PRNGs include:
Efficiency
Deterministic
Periodic
These characteristics of a PRNG make them suitable for applications where many numbers are required and where the same sequence can be played easily.
For instance, simulation and modelling applications. For use cases where the numbers need to be really unpredictable such as data encryption, it is better to use TRNGs.
TRNGs, unlike PRNGs use the randomness from physical phenomena and then introduce it to the program. So, imagine the die connected to a computer but in reality, people use something that's easier to connect to a program. Such as mouse movements or the time between keystrokes.
There is no leap of faith required to enjoy games at online casino websites such as https://casino.netbet.com/in/.
If you have used any online casino site, then you may have noticed the similarities with video games. If you play a game like poker at a live casino, every hand is truly random. This is owing to the dealer physically shuffling the deck to create randomness.
What happens in online casino games is simply a statistical approximation of the random roll of dice or shuffling of hands. This is where RNGs come into play.
The RNG programs used in casinos involve the use of a seed number. The seed number is used by the algorithm to generate a random number. That decides the card that is drawn from a deck of cards or the position a die lands on.
Similarly, it also decides the place where the roulette ball lands or the position of the slot machine reel.
This new random number is now used as the seed to create the next random number and the process is repeated.
Yes, there is a pattern here. But it is impossible to decipher this pattern if you don't know what the original seed number was. This is a heavily guarded secret and considering that the seed number is too long, many sites use numbers that have nearly 299937 digits. This means that hacking is next to impossible.
However, to verify that the casino you are playing at is legit and is using RNGs, you need to check their licenses and certifications carefully. Most online gaming and gambling sites like https://sport.netbet.com/in/ get their software audited regularly and also share their certifications for the world to see.
Most casino software is tested by certified Quality Assurance people, which are usually third-party testers. They undertake the full gamut of evaluations such as RNG evaluations, game and mathematical testing, ongoing RNG or game pay-out verification, live dealer testing etc.
There have been instances in the past where the casinos had rigged their software, but they were caught.
Random Number Generators or RNGs are complex programs that ensure casino games (among other things) are as random as can be. The credibility and reputation of casinos depend on the fairness of RNG software.
Thanks to RNGs the outcomes of online casino games can't be predetermined, rigged or hacked in any way and all online casinos have the seal of approval from independent auditors and regulatory bodies.
