While some casino games have a skill element within the outcome, some casino games are purely according to chance. Because all online casino games are partly or completely driven by chance, all casino games rely upon a random number generator, or RNG within the software that powers the game. The RNG is a mathematical application that does exactly what it says: generates a totally random number. Not all RNGs are the same, and they have to be tested extensively to ensure that the numbers they generate really are random.
In some games, the use of an RNG has an obvious role. In European roulette, as an example, the RNG generates a number from 1 to 37 (with 37 corresponding to “0”) on the roulette wheel. The RNG generates a number, the casino stops, and bets are paid or forfeited.
In craps, the RNG must generate two random numbers simultaneously, as well as in single deck card games, the RNG must generate a number from 1 to 52, with each of those numbers corresponding to a certain card. During an individual deck card game, the RNG has to “remember” which cards it has already dealt to ensure that they will not be dealt again. With multiple-deck games like online blackjack, the RNG has an even more complicated mathematical algorithm driving it.
Some RNGs require the user to specify an initial “seed” value, which itself varies randomly. Many of them use the time on a clock as a seed, in order that there is absolutely no human intervention at all in the RNG. You will find some RNGs that actually involve numerous RNGs running all at the exact same time, with one RNG picking from among the results, creating a sort of super-randomness to the calculation. Remember, they are very oversimplified ways of describing how RNGs work, but it gives you some notion of the “brain” behind the many online casino games you enjoy.
To be deemed as fair, numbers spit out by any RNG have to be unpredictable and unbiased. To ensure that this is the case, internet gaming platforms have to be tested regularly by independent testing entities like eCOGRA. The testing groups have to test the RNG algorithms over millions of hands of card games or millions of throws of dice to make certain that the numbers are unpredictable and unbiased.
In your online research about internet gambling, you may stumble across someone or site telling you that a certain slot machine has a “cycle” which is predictable enough that you can learn when it’s “due” for Continue a jackpot, or which could want to sell you some sort of system for predicting hits. These ploys aren’t gambles at all: they are just good ways to throw away your money. Save those hard-earned dollars for something else!
