What is an RNG?

RNG stands for “random number generator” and it is a category of software that performs a task that sounds easy, but is actually a marvel of mathematics, programming, and engineering. If someone asks you to think of a number at random, you might think that your reply is actually a random answer, but it isn’t. Your reply will be influenced by any number of factors. True randomness is extremely difficult to simulate. In order for casino games to be fair, however, a solution had to be devised, which is where RNG’s become extremely important.

Bonus Chips | Spin PalaceWhen you think of the differences between casinos, you picture the graphics and sounds first. Those are merely window dressing for the only important thing in the casino. The only thing that counts is the random number generator and how it is programmed to act. See it work at AU online casinos.

There are four major companies in the world that provide the majority of random number generators that fuel the entire industry. They are Random Logic, Cryptologic, Microgaming, and Playtech. These companies also provide the graphic interface, and in the case of Random Logic, the entire casino, but the true business they are in is the random number generator software business.

A random number generator is in essence just a computer program that simulates what happens when you throw dice or let a wheel at Pokies come to a stop on its own or shuffle a deck of cards. It does this by using algorithms of amazing complexity. A more accurate description of software RNGs is actually something called a pseudorandom number generator, or PRNG.

The fact is that truly random results can only be attributed to natural phenomena. Where the rain falls is truly random. How the current flows in a river is also truly random. An algorithm, however, has a computational key, and thus is not truly random. The magic of online casino RNGs is that they manage to take a pseudorandom system and program it to produce results that are statistically comparable with the true randomness of nature. This can only be accomplished with massive number computations.

There is a benefit to both casinos and players alike in the use of a computational random generation system. It allows the casino to set up clearly defined parameters of randomness desired, and the machine takes care of the simulation. It can essentially be programmed to perfectly simulate the predicted random results in a six deck blackjack shoe, for example. Or it can perfectly simulate the expected number distribution for a roulette table. The numbers will never repeat, so the simulation is comparable to the real thing. This is what independent auditing companies check for when they do their monthly analysis of casino software. They make sure that the RNG is producing numbers in keeping with what is to be expected of the advertised payout rate. Take advantage of this payout rate at Eurogrand Casino.

What this means in the end is that if a casino advertises that it has a 99% payback percentage, the house edge is exactly 1%. This number will remain accurate into perpetuity until the RNG is reprogrammed. This means that out of every dollar that goes into a game 99 cents are paid out to players on a completely random basis. In essence the casino aggregates cash in each game and redistributes in in differing amounts and at differing times. 99 people might lose one dollar and the 100th player might win $99. Or, keeping with the 100 player example, 40 people might lose a dollar, the 41st player might win $29, leaving $10 in the machine, and 59 more people might lose a dollar. To portray this example simplistically is difficult because the permutations are almost endless. A casino game is a type of Robin Hood that does not distinguish between the rich and the poor. It takes from all and gives to anyone.

All machine payback rates are advertised in casino websites. They differ for every game, and are designed to mimic the odds distribution one might find at a real casino. Oftentimes, the odds of winning are actually much better online than in the brick and mortar counterparts. It is not unheard of to find some machines designed to pay back above 100%, meaning they lose money in the long run. Most machines, however, will take a marginal amount for the casino in the long term, while paying back up to 99% to players as they come and go. It is important to check whether it is a PayPal Casino or not.

This is not to say that it is possible to wait out the payback schedule on a game. The way RNGs work is by calculating massive numbers with billions of permutations. One would have to play billions of times in order to gain back slightly less than he already put in. The system is based on random payouts. Some people will win and others will lose. The truly random part of the equation is when a particular person might be at the right game at the right time.
