Learn About Random Number Generators at Online Casinos

Posted On: Jan. 30, 2013

It's pretty obvious that online casinos don't have decks of cards, dice or any of the other trappings of casino games. For that matter, they don't have slot machines or video poker machines either. So how does the casino software simulate all of these things? It uses random number generators which take the place of the physical props. Carefully checked for accuracy, these programs keep the games just as fair as their physical counterparts - and in some cases, even more so.

Put in plain terms, a random number generator (RNG) is a computer program that constantly cycles through a certain amount of numbers and selects a random one at a specific time. For example, the RNG in a craps game is set to pick between the numbers one through six to represent the rolling of a standard die. Once all of the players bets have been placed, the RNG stops wherever it is in its sequence, and the number selected is the one that is "rolled" on the die. The same theory can be used to pick from any amount of numbers, making it a multi-purpose tool for online casinos.

Even games like online slots make use of RNGs to come up with one of the thousands or even millions of combinations of symbols on their reels. What many players don't realize is that this technology has been in use for some time, and that even many physical slot machines have replaced mechanical reels with RNGs. To ensure their accuracy, the RNG software used for online casinos is rigorously tested on a regular basis as part of the licensing process. From a mathematical standpoint, RNGs don't come up with entirely random results, but they are close enough for practical purposes.

Random number generators can actually make casino games more fair than physical games because they never wear out or develop any imperfections. Dice may have defects, and a roulette wheel can develop a bias, but an RNG will operate perfectly for as long as the online casino is in business.
