Random number generation has existed since ancient times, with simple methods of producing different numbers for example, rolling of dice, shuffling of playing cards and flipping coins. These methods required a lot of physical effort, time and manpower to generate any large quantities of numbers, so the development of digital random number began.
What are Random Number Generators?
Random number generators are computer programs. They contain algorithms that generate numbers in a seemingly random sequence. The casino industry utilizes what is known as “pseudo random number generators” and are so named because the number sequences are not 100% random.
Although random number generation is a seemingly complex mathematical process, Pseudo random number generators have a relatively simple principle that governs them. What makes them different from other forms of random number generation is that they don’t need any external input of information in order to function.
They use only a seed number, which is basically a starting point number, and then an algorithm, which takes the last number or last 2 numbers, and then applies a complex mathematical formula of subtraction, multiplication, division and addition to product a supposedly random number.
This explains why pseudo random number generators aren’t completely random, because in mathematics, there will always only be one correct answer to any equation. The input of the equation will always have only one correct output. However, the volumes of numbers, which are able to be generated, are totally sufficient for the casino games purposes.
Casinos and Random Number Generators
Casinos use pseudo random number generators for online games, where there are no physical dealers.
In a brick and mortar casino, in Roulette, it’s the wheel that contains the RNG – the wheel spins, and the laws of physics dictate when it stops, with no way of truly predicting where the ball will land. In dice games, the rolling of the dice produces the numbers and in card games, the RNG is in the shuffling of the deck. In slots, the program is inside the cabinet of the machine, and determines how long the reels spin for.
Random Number Generators in Roulette
Roulette is historically one of the most popular casino games. It is a game that relies completely on chance, with the odds being typically around 2.7% for European Roulette, and around 5.3% for American Roulette. With the advent of online roulette, casinos needed to find a way in which to duplicate those odds electronically, as well as a way to assure their punters that the numbers were still produced randomly.
RNGs provide that assurance. There are independent testing bodies for the casino industry, who continuously test to ensure that the random number generators being used are authentic, so players can be comfortable in the knowledge that the game does rely on chance. Likewise, the online casino can be assured that players are unable to apply roulette strategies, as the numbers are impossible to predict, thus everyone has a genuine casino experience.
Roulette is one of the easiest games in which to use random number generators, as only a single number is required to be generated per spin. In online Roulette NZ European games there are 36 pockets, so the program needs to product a number between 0 and 36. The algorithm uses multiple digit numbers, which are then reduced in order to fit the numbers between 0 and 36. In this way, online roulette games software then decides where the ball stops randomly.
There is an element of trust between players and their online casino of choice. With the wide variety of online casino available to players nowadays, an untrustworthy casino would soon go out of business. Random number generators provide the security and reassurance for both players and the house, that the games being played are still authentic games of chance, as they always have been.
