While some casino games have a skill element within the outcome, some casino games are purely based on chance. Because all online casino games are partly or completely driven by chance, all casino games count on 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 completely random number. Not all RNGs are exactly the same, and they have to be tested extensively to make certain 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 has to generate two random numbers simultaneously, and 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 a single deck card game, the RNG must “remember” which cards it has already dealt so that they will not be dealt again. With multiple-deck games like online blackjack, the RNG has an much 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, so that there isn’t any human intervention at all in the RNG. You can find some RNGs that really 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. Keep in mind, they are very oversimplified ways of describing how RNGs work, but it provides you with 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 really is the situation, 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 ensure that the numbers are unpredictable and unbiased.
In your online research about internet gambling, you could stumble across a person or site telling you that a certain slot machine has a “cycle” that is predictable enough that you could learn when it’s “due” for beginners a jackpot, or that will 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 hard earned money. Save those hard-earned dollars for another thing!
When selecting among online casinos, you should look for ones whose gaming software is tested by eCOGRA, Certified Fair Gambling (CFG), Gaming Associates, BMM International, Technical Systems Testing (TST), Price Waterhouse Coopers, or another reputable independent auditor. A casino online that is up front about its software platform and independent auditing is far more prone to provide you with a fair and fun internet gaming experience.
