What is a Random Number Generator (RNG)

what is a random number generator

If you like non GamStop casino games, then you are definitely familiar with the term random result generators or (RNG). All games at non GamStop casinos at (except for some live games) are developed with an RNG component which generates random outcomes with each round. In general, this technology is used in all sectors of the gaming industry, including software engineering, computer simulation, and cryptography. It works in a very simple way as the algorithm scans all possible results and chooses one outcome. Since this technique has no memory, it gives a different result in each time, so it is not possible to predict what will be the next result. In this article, we will explain in detail how this technique works and how you can check its fairness yourself.

The Dice, Playing Cards, & the Roulette Wheel!

The most famous RNG is a die. Not only in gambling games but also in board games such as monopoly and goose boards are played with dice.

There are only six outcomes with a classic dice, but each outcome is equally likely to come by. You can easily roll six two or three times in a row, for example, but if you roll hundreds of thousands of times, all six outcomes will come along about the same number of times.

In the casino game Sic Bo and the Diceball offered in land-based casinos, the die is used as a random generator.

A deck of cards by itself is not an RNG, but cards can be used as RNG if you shuffle them properly. After shuffling seven times, the order of the cards is so unique that it is virtually certain that that order has never happened before. The number of possibilities is unimaginable with 52 different cards in the deck.

A shuffler is very useful, but a good dealer will bring just such a random order to the cards. Cards like RNG are used in many games, including casino games like Blackjack, poker, Caribbean Stud, and Pai Gow.

A well-balanced roulette wheel with a neatly spherical ball and a croupier who skillfully moves the ball also ensures a random outcome. The roulette wheel along with the bullet is the RNG.

Bingo and Keno use a bingo mill on which a ball with a number is randomly rolled. If you are going to hand fish balls from a raffle yourself, the RNG is not guaranteed as it is easy to influence the process.

Difference Between the Software and Hardware RNG

In the previous examples, the Random Number Generator (RNG) was a material element of the game. In Sic Bo, you bet on the outcome of the dice, in blackjack you bet on which cards you will get, and in roulette and bingo, you bet on which number the ball will land.

But in many other cases, the RNG itself is not the game element, but a game does need an RNG. For example, a slot machine lets you collect watermelons, bells, and lemons in a row to win money. But they have to come by randomly and unpredictably, otherwise, players can foresee what’s coming and empty the game’s pot. And that’s the last thing a casino wants.

To determine which reel ends up on which symbol, there isn’t someone in the developer’s headquarters dealing cards or rolling dice 9 hours a day. Inside the slot machine is a computer that contains an RNG; a software solution to determine a random number. Or there is a hardware component that handles the RNG calculation. Or the slot machine is networked to a central computer that contains the RNG. Because computers can also produce random numbers, although that is even more difficult than you may think.

If you search for ‘Random Number Generator’ on Google, you will be presented with a solution from Google itself. On the right, you can enter the series, and a big ‘generate’ button gives you a random number within that series. No matter how many times you press, you can’t accurately predict what the next number will be.

No Trust

You can see a dice and it is easy to understand that the outcome is random. An RNG is invisible, the algorithm that spits out the random numbers is not transparent and difficult for people to understand.

Gaming commissions that grant licenses to online gambling sites require RNG auditing from an independent lab like Gaming Laboratories International and eCOGRA.

Casinos Make Money Because They Have House Edge, Not Because They Cheat!

Companies that offer games of chance, whether in a land-based casino or on the internet, make money because they have a house edge! For every casino game, it is possible to calculate, or generally known, what the house edge is.

Yet people sometimes doubt the Random Number Generator (RNG) that non GamStop casinos use. If you lose 20 rounds in Blackjack or lose for the umpteenth time in poker, you can start to doubt whether everything is fair. That is why non GamStop casinos often announce which certifications their RNG has received. On the other hand, you can win consecutive spins in any of the casino games and withdraw your winnings easily. In either case, the casino games remain completely fair and random.
