1) An RNG (random number generator) is at the heart of all modern slot machines. These include traditional reels, video reels, video poker machines, video blackjack, and video keno. 2) Every RNG in every slot machine is tested and licensed in all regulated gambling jurisdictions in North America. Random number generators are the main part of the slot machines. The earlier slot machines were mechanical and required physical reels but they evolved with time and now they are completely digitised. A computer chip is used to pick random numbers. As everyone do not know the functioning, there are many myths and misconception related to them.
The numbers produced by the Random Number Generator in a slot machine are not truly random because they are the result of a mathematical process. If you knew the formula used and the value of the last random number generated, you would be able to calculate the next random number that would be generated. The RWB Ping Pong Ball Game is just like a 95% payback slot machine. Even though the outcomes in both games are chosen completely at random, each pays back 95% of the money played in the long run. A slot machine works very much like the RWB Ping Pong Ball Game. Conceptually, there is a basket of ping pong balls for each reel.
Slot players usually know that there's a computer chip called Random Number Generator or RNG inside the slot machines but they don't usually know how it really works. That's why there are a lot of urban legends and misunderstandings about the slot machines and similar casino free games. Probably one of the most popular legends about the slot machine is that somehow it tells the player exactly when it's about to give a jackpot. There's a lot of con artists trying to sell you their 'system' of being the slots. Don't get fooled by them, save your money for other things, because it's totally impossible.

The Random Number Generator is actually a microprocessor just like the one in your computer. But instead of running a browser or the programs you normally use, it runs a different sort of computer program. The RNG generate different numbers that gives you the symbols on the reels of the online slot machines. These numbers are constantly changing fast, they change in milliseconds. The RNG selects different numbers that range approximately from 0 to four billion. These numbers have a direct correlation with the symbols on the reels. The result of the combination of these symbols is anchored by the number that is generated by the RNG. The second you press the spin button is when the number is selected.
There's an algorithm or a formula that is programmed onto the RNG chip. This program in the Random Number Generator gives instructions to generate and select the numbers. The Casino Control Board and other labs test the algorithm and how it works on the Random Number Generator so that it is accurate. The random numbers that it generates is so vast and complicated that it is beyond any ordinary person's mathematical knowledge. It takes teams of programmers and mathematicians to come up with this algorithm and test it. The program is tested for performance and correctness so that slot players are not cheated through a custom random number generator.
Knowing the technicalities of course doesn't really explain the average slot player how the true random number generator actually works. In order to really understand the random number generator, you need to know how you win at slots. Random number generator plays a big role in determining when a spin is going to result in a win. There's a couple of spaces that are either a symbol or a blank on each reel in the reel type slot machines. These are known as ‘physical stops'. In the old mechanical slot machines, there are reels that have about 20 symbols but in the new slots, there are 22 physical stops. The slot machines that have the Random Number Generator microprocessor makes it possible to have more stops. These are called 'virtual stops'.
If you simplified things and say that there's only ten stops on each reel, you'll still have a thousand different combination for the symbols on the reel. You get this number by multiplying the number of symbols on the reels. For a 3 reel slot that's: 10x10x10= 1000. This thousand is called a cycle. This is the term that most confuses slot players. Most players think that the thousand determines whether they win or lose.
In this case, the chance of the right 3 reel symbol combination picked is one in a thousand. That means, theoretically if you played one thousand spins you should see the right combination once. But we all know that this is not true. Even if you played a million spins, you'd see the numbers even out to the actual probability. If this is too confusing, think of it as flipping a coin a hundred times. The odds of having heads or tails are 50:50. You're not going to see fifty tails and fifty heads after a hundred spins.
We've all seen how the lottery drawings are picked on a daily basis. There's three glass bowls which contains ten balls that number from 0 to 9. The balls are mixed and when someone lifts up the top, a ball with a number pops up in the tube, that's the first number. The same thing is repeated for the second and third glass bowls and you get the three numbers for a winning combo.
If you use this case, replace the numbers 0 to 9 on the balls with the symbols on slot machines. Each bowl have one ball with the slot symbol for the jackpot. Two balls with a bar, three with a banana, and four balls that are blank or spaces. The Random Number Generator is the person picking the winning combo of the symbols. So if you put that in the thousand odds, you're going to get the following winning combination:
- 3 Jackpots 1 (1x1x1)
- 3 bars 8 (2x2x2)
- 3 bananas 27 (3x3x3) so you get total 37 wins.
But there's also 963 combination that you'd lose which are combinations of the following:
- 3 blanks
- 2 blanks and a symbol
- 1 blanks and two different symbols
- 3 different symbols.
Rng Slot Machine
The Random Number Generator picks the combo of numbers a thousand times in a second. Think of it as a string of blinking lights, like the Christmas lights, but there can be one bulb that is lit at any one time. Electricity is going through one bulb to the next bulb down the string. When you push the ‘spin' button the electrical current stops and the bulb in that particular position would light up. The light represents the three digit number in this case. It's the same when you get up from a slot machine and see someone else sit there and hit the Jackpot. The chances of you winning or hitting the Jackpot combination at the same exact millisecond are phenomenal. That's how Random Number Generator operates, and it depends on that and determines the results of your play.

One of the questions I'm asked most often is - 'how is it possible for a slot machine to be a random device and for a machine to also pay back a certain percentage of the money played throughit?' If the results are truly random, people argue, then the payback should be random too.
Despite the fact that this governor function does not exist and in all jurisdictions whose regulations I'm familiar with, it is possible for the results on slot machines to be determined atrandom and for machines to have specific payback percentages.
It's difficult to reconcile the fact that results on slot machines are random and for us to be able to know what will happen overall on amachine. Let me illustrate how this is possible with my RWB Ping Pong Ball Game.
Suppose I have a basket that contains 100 ping pong balls. Eighty ping pong balls are white, 15 are blue, and five are red. You draw a ball at random from the basket. There's acover on the basket, so you can't tell what color ball you're drawing. Also, you can't tell the balls apart, so you're no more likely to draw one ball over any other. After you drawthe ball, you record the color and put the ball back in the basket.
As you repeat this action, you will find that the percentage of draws that were red balls gets closer and closer to 80%, the percentage of draws that were blue balls gets closer and closer to15%, and the percentage of draws that were red balls gets closer and closer to 5%.
We know that this will happen because you draw the balls at random and each ball is equally likely to be drawn by you. But it is not equally likely that you will draw any particularcolor. Eighty percent of the balls are white, so we expect 80% of your draws to be white. Similarly for the blue and red balls.
Even though you drew the balls completely at random, the distribution of colors you recorded will match the distribution of colors in the total population of ping pong balls in thebasket. Random does not mean that everything is completely unpredictable and unknowable.
Now let's make the game more interesting. You have to pay me $1 each time you want to draw. When you draw a white ball, I keep the dollar. When you draw a blue ball, I return your dollar.And when you draw a red ball, I pay you $16. A nice payoff for drawing the red ball.

Looking at this game from my perspective, I have a 15% chance of paying you $1 and a 5% chance of paying you $16. Calculating this out, we have 0.15(1) + 0.05(16) = 0.15 + 0.80 =0.95. On the average, then, for every $1 you give me to play, I will return 95 cents to you.

The RWB Ping Pong Ball Game is just like a 95% payback slot machine. Even though the outcomes in both games are chosen completely at random, each pays back 95% of the money played in the longrun.
Are Slot Machines Random
A slot machine works very much like the RWB Ping Pong Ball Game. Conceptually, there is a basket of ping pong balls for each reel. But instead of having different colors on theballs, these balls have symbols representing the different symbols on the reels on them. Some symbols appear on more balls than other symbols.
Let's set up a basket of ping pong balls for a reel from a real Double Diamond slot machine. Even though there are 22 symbols and blanks on the reel, our basket will have 72 ping pongballs in it. Having more balls in the basket than we have stops on the reel allows us to alter the probability of landing any particular symbol on the payline from what it appears to befrom counting the number of times it appears on the reel and dividing by 22.
The reel has 11 blanks on it, but I'm going to put 31 blank ping pong balls in the basket. Half the stops on the physical reel are blanks, but slightly less than half the ping pong ballsare blank, so it's actually a little less likely than it appears for a blank to land on the payline on this reel. There's only one cherry on the reel, but I'm going to put two ping pongballs with cherries in the basket.
All of the other symbols – single bar, double bars, triple bars, 7, and Double Diamond – appear twice on the reel, but the number of ping pong balls with each symbol in the basket is 25,4, 6, 2, and 2, respectively. We need about 6.5 ping pong balls with each of these symbols in the basket to have the probability of drawing a ping pong ball carrying the symbol be thesame as what appears to be the probability of having the symbol land on the payline from looking at the reel, so you can see how different the true probabilities are from what the reel makesyou think they are.
Just as with the RWB Ping Pong Ball Game, the more you play this Double Diamond machine, the closer the distribution of symbols landing on the payline will get to the distribution of ping pongballs with each symbol in the basket.
Manipulate A Random Number Generator Slot Machine
Even though it sounds like random should mean completely unpredictable, the only thing we can't predict is what color ping pong ball you'll draw next or what symbols will appear on the paylinenext. Because we know the distribution of ping pong balls in our basket and the casino knows the distribution of symbols on the slot machine's reels, we can predict -- no, more than predict, wecan calculate with near certainty -- how much my game and how much a slot machine will pay back in the long run.
The only reason we can't be dead certain of how much a machine will actually pay back is because the outcome of each game is truly chosen at random and there is no function forcing the paybackto a particular number. But given enough draws or spins, my RWB Ping Pong Ball game and a 95% payback slot machine will both pay back very, very, very close to 95%.
How Does A Random Number Generator Work On A Slot Machine
To sum up, there's no attempt in the programming of a machine to force it to a particular payback percentage. There's no need to. Random sampling from a known population takes care ofit automatically.
