Guide To Random Number Generators

In live casinos, decks are routinely inspected and replaced as needed; devices are regularly inspected and repaired; roulette wheels are rigorously tested and monitored; and even the dealers are rotated multiple times per hour. This and more is how a live casino ensures the activities it offers are fair and legitimate. How do online casinos achieve the same results?

The majority of online casinos do not use real roulette wheels or card decks (though some do, using real croupiers and webcams to transmit the deal or turn to players), instead relying on Random Number Generators to ensure a fair game.


Continue reading to learn more about Random Number Generators, including what they are and how to identify them.



What is the function of a random number generator?

A Random Number Generator is merely a computer program that generates a sequence of random numbers. These then correspond to the online casino’s roulette wheel, card decks, dice, slot machine reels, or any other application of chance-based games. Many modern lotteries in a variety of countries even prefer RNGs to traditional draws.


Numerous industries utilize Random Number Generators, but online casinos utilize them the most frequently. The generation of random numbers determines the outcome of each shuffling of a virtual deck of cards or turn of a virtual roulette wheel. This eliminates the need for any of the precautions employed by live casinos, as the Random Number Generator governs each and every game’s outcome in a completely random manner. This ensures that the stated return to player percentages and house edges are accurate.


Protection of RNGs

Third-party companies approve and audit the Random Number Generators of online casinos to ensure that they are genuinely random and cannot be compromised by players. A test of a RNG will involve continuously testing hundreds of millions of numbers to guarantee a representative statistical sample.


Using these hundreds of millions of trial runs, online casinos frequently test their Random Number Generators, which are then certified by a third party company. Generally, players will be able to locate this certification on the online casino’s website, or they can contact the casino directly if they are unsure about the Random Number Generator.


Different Uses

Random Number Generators are also utilized in programming and cryptography due to their capacity to generate vast quantities of random data, which is extremely useful for debugging and writing protocols. In order to maintain the validity of the scientific method, they are also widely used in science for a variety of experimental procedures.


Contrary to prevalent belief, functions such as the “shuffle” button on a music player are not random, as they are programmed to prevent multiple repetitions of the same song. A truly random progression implies that the probability of 2, 2, 2 is the same as that of 1, 2, 3 or 6, 11, 9. The “shuffle” function of a music player is referred to as pseudo-randomness and, if subjected to the same tests as a Random Number Generator (see above), will exhibit evident patterns over time.


In roulette, the odds of the ball landing eight times in a succession on black are identical to the odds of any other red or black pattern. A Random Number Generator ensures that the outcome of each spin is completely independent of the outcome of the preceding spin. In contrast to the music player, there is no reason why the number 19 cannot appear on consecutive rotations. This page contains additional online casino guides.
