Random Number Generator Online Casino
Part 1 – Random Online Casinos
This is done through the use of random number generators. Random number generators are a vital component of online casino software, as randomness is an integral aspect of casino games. We explain just why randomness is so important below, and provide a detailed explanation of exactly what random number generators are. The Random Number Generator ensures that each spin on the slot link s to a random number. The random number (a unique outcome of an algorithm) then translate s into a result of the spin (or the bet). It could be a prize or no prize (a loss of the bet). The outcome of the spin then translate s into a visual display on the screen. When you’re at the casino or maybe using an online casino and you’re struggling to find the winning combination of numbers, why not try our random number generator, we give you different amounts of numbers to use, The random number generator which is designed for use with american roulette gives you lots of options for how many numbers you may want it to generate, you could start off using just one number then two or maybe you want to jump straight in and use the 10 numbers.
In order for a computer to arrive at a number, you must tell it exactly how to arrive at that number. In doing so, you can give the computer other numbers, operators (addition, subtraction, multiplication, etc), and formulas. For example; you could tell the computer to start with the number 2, perform a torourous set of operations on it, and it would give you the result (lets say 25). No matter how complicated the instructions you gave the computer, every time you tell it to start with 2 it will always give you 25 back. Obviously in order for top online casinos to simulate blackjack (or any other casino game) they must have some way of making different combinations of cards come up each time you play.
How Do Random Number Generators Work?
The only way to get a different result from the computer (still following the 2 & 25 example) is to tell it to start it with a different number. This is preceisely what (pseudo) random number generators do. Instead of telling the computer to start with 2 the RNG might tell the computer to check your computer’s clock and use whatever number the second hand is at. This would lead to 60 different possible outcomes (there are 60 different numbers the second hand might be at). This is certainly better than nothing, but not something you’d be able to base an online casino off of. Players would quickly learn that hitting deal at just the right time would always net them a winning hand.
Another method might be to use a number like Pi (3.1415926535897932384626433832795028841971…). Pi is an example of an “irrational” number. This means if you were to write out say the first 1,000,000 digits of Pi you would not find any repeating pattern in the digits. In fact, no matter how many digits of Pi you wrote out the series would never begin to repeat itself. Using an efficient algorithm a computer can crank out the first billion digits of Pi in very little time. Going through the first billion digits of Pi would be a great way to generate random numbers. Unfortunately this plan would fail for an online casino if one of the players ever found out about it. It might take the player a while to figure out the formula for how the digits taken from Pi were used to determine the cards on his screen, but as soon as he did he’d be able to predict future cards and have a huge advantage over the house! Another way it might fail would be if the digits of Pi just happened run in such a way that they gave the player more winning hands than usual.
The actual method used to calculate pseudo random numbers is sort of a combination of these two methods. First a “seed” is generated by checking the computer’s clock, or some other number the computer has access to that is constantly changing. This seed is then used to pick a point in the number sequence to jump in at. For example if the seed was 624,053 the RNG might jump to the 624,053th digit of Pi and begin using numbers from this point on. Even if one of the players knew his BJ hands were somehow related to the digits of Pi it would be more difficult to find how they were related if he had no idea where in the sequence he was.
So Is Pi Commonly Used To Generate Random Numbers?
I don’t believe so. In fact it’s not very convenient for a computer to have to keep track of a billion different numbers just to generate pseudo random numbers. Instead what usually happens is that a complicated formula is used to calculate a “random” number from the initial seed. This “random” number is then plugged right back into the same formula (as if it were the seed) to generate another “random” number. This second “random” number is also put through the same formula to generate a third “random” number. This process is repeated every time another “random” number is desired. How well this process works depends on the function used. If a poor function is used you might see a sequence like:
0.99743, 0.65031, 0.10550, ….(skip 1,000 numbers)…, 0.96523, 0.65031
What wrong with this sequence is that one of the numbers has repeated. Since the next random number is determined by the last number generated the next number in the sequence above would have to be 0.10550. Then after another 1,002 numbers the cycle would repeat itself again. Repeating cycles are a bad thing because an alert player might be able to use it to predict the outcome of his bets, or even worse the 1,000 blackjack cards corresponding to these numbers might lead to a larger percentage of hands in which the player wins than usual. There are a lot of other things that can go wrong with these pseudo random number generating functions, but they all lead to the same problems:
- The player is able to predict the sequence, or
- The sequences tend to favor the player or the house.
Why would an online casino be very interested in how good their RNG is? For the game of blackjack I can’t imagine too many casinos caring if they discovered that their RNG formula was slightly biased against the player.
Part 2 – More About Online Casinos Random Number Generators
On the other hand, let’s consider the game of roulette. If the RNG function was slightly biased such that the number 9 tended to come up more often than any other number, this could cost the casino if a player ever discovered it. In fact any bias would favor the player in roulette if he knew about it. Because of this a RNG function must be thoroughly tested before being used in casino software. Now let’s consider a more subtle case. There are really only so many biases an online casino can test for and if they really wanted to eliminate them all they’d probably never find a usable RNG function. A subtle bias might be something like 0 showing up more often than expected on all spins following a 9. Perhaps there are many different subtle biases like this that would let any player make a killing if they were aware of them. It’s interesting that although a biased wheel could be a real problem for a land casino these subtle biases only effect online casinos. Of course an online casino could easily overcome such problems by making their software “non-random” (i.e. “invincible mode”) at times against the player.
If online casinos use a fair RNG why won’t they release the formula they’re using to prove it?
Going back to the roulette example, it would be almost impossible for a player to find subtle biases in the game. It’s not unthinkable for the pattern 9, 0 to emerge a few times in a roulette session consisting of a large number of spins. In fact if you were to record a few thousand spins you’d find several number pairs that showed up more frequently than others. Whether this is because of a true subtle bias, or simply chance is difficult to say. The only practical way a player could find subtle biases would be to experiment with the casino’s RNG formula. It wouldn’t be hard to write a computer program to simulate 1,000,000,000,000 roulette spins at a given casino if you knew their RNG formula and then to analyze the data in search of such subtle biases. This is one of the reasons online casinos might not want to reveal their RNG formulas.
If an online casino is using a fair RNG why would they need to change the formula?
One obvious reason would be that the RNG wasn’t really fair to begin with or that they wanted to “rig” their casino. Another possibility relates to the subject of subtle biases. Even thought most online casinos will test their RNG functions against a battery of “randomness tests” passing these tests doesn’t insure the function is completely without bias. If a year after releasing their software they discover a subtle bias they might have missed before or they notice a player is winning in a way that seems suspicious it might make sense to slightly modify the RNG formula to destroy the biases. Yet another possibility would be that the casino was in a rush to get their software to market. Because of this they settled for a less than perfect RNG function that failed some randomness tests. It was the best they had at the time and now that they’ve had some more time to develop a superior function they would like to use the new function.
Is there any way for a computer to obtain truly random numbers?
There’s a debate in philosophy over whether such a thing as “free will” (usually thought of as unpredictability) exists or whether our world is a deterministic one. I’m not going to touch this debate, but instead consider “true random numbers” simply to be numbers that cannot be predicted by another person using any mathematical formula.
The answer to this question is yes. Encryption programs commonly obtain truly random numbers by asking the user to type a sentence using the keyboard. By measuring the time between each keystroke essentially random numbers can be obtained. Unfortunately this solution isn’t really feasible for online casinos unless they want to employ people to randomly press keys all day long. Another novel approach involves radioactive decay. A geiger counter is an instrument that creates an electrical current every time a charged particle passes through its sensor. Since the time between each radioactive decay (which shoots off a charged particle) in a given material is unpredictable the bursts of current through a geiger counter is also unpredictable. Based on the type of material it is possible to say on average how much time will pass between each decay, but it’s impossible to predict exactly how long it will be between two particular decays. Hooking a geiger counter up to a computer would be an ideal method for determining random numbers.
You don’t have to take a leap of faith to enjoy games at a live casino in London, Glasgow, Birmingham, Liverpool, or anywhere else in Britain. Whether you win or lose, you’ll know you had a fair shot. Not only does the UK Gambling Commission license and regulate casinos, but you can’t count on the laws of physics for random and fair play. Whether your game depends on the momentum of the roulette wheel, roll of the dice, or card shuffling, it’s not hard to trust what happens when you can see the action physically unfold before your eyes.
Fortunately, you don’t have to mindlessly hope for the best when playing online. Even though most online casino games are effectively computer simulations, gambling sites use RNGs or random number generators to mirror the real-life odds. Keep reading to learn how these sophisticated algorithms make internet gambling possible.
Random Number Generation Basics
Random number generation can be a complicated topic, even if you are well-versed in mathematics. Yet you don’t need to enrol in a graduate computer science programme to understand the fundamentals. If you prefer, you can be completely oblivious to how RNGs operate and still play to win. Nonetheless, many casino players are interested in numbers, patterns, and the way games work, so it’s definitely worth exploring.
If you’ve spent any time playing online casino games, you’ve probably noticed how much they have in common with video games. The most sophisticated video slots now feature gorgeous graphics, impressive animations, and infectious soundtracks. In addition, all games are made up of untold lines of computer code, but it’s the RNGs that are of interest here. When you play a card game like blackjack at a live casino, every hand is random. That’s because the dealer physically shuffles the deck to mix up the cards. If you’re the shooter playing craps, where the dice ultimately land depends on the laws of motion. Yet what happens in most online casino games are statistical approximations of what might take place in reality, which is where random number generators come into play.
When you play at a trusted internet gambling site, the random number generator ensures that the games are fair and the probabilities mirror real world outcomes.
How RNGs Work at Online Casinos
The whole idea of random number generation becomes complicated if you understand how computers operate. As most people know, computers are programmed by humans. In other words, they merely follow the instructions we give them. Even though that might not appear to be problematic, it does create a major technical dilemma. If computers rely on human for input, the output can’t really be random. Any mathematical formula you could possibly create would be predictable and could theoretically be decoded by hackers. Naturally, programmers have come up with a fool proof solution, which involves using a seed number. This seed number is used by the computer algorithm to produce a random number that determines which card is drawn from a deck of cards, what number a die lands on, where the roulette ball ends up, or the position of a slot machine reel. What happens next is even more interesting. That random number is also used as the seed to create the next random number and the process continues over and over.
If you see a potential flaw in this process, you aren’t alone. While there is a pattern, it’s impossible to decode if you don’t know the initial seed number, which is heavily guarded. Also, the seed number is quite long, with many sites using numbers that contain 219,937 digits, which means hacking is out of the question. When you play at a casino that’s licensed by the UK Gambling Commission, you’ll have assurances that RNGs are fair. Sites not only have their software inspected regularly, but they post their certifications for you to see. You can look for logos from the likes of iTech Labs, eCOGRA, and TST.
Trusted RNGs never rest. They operate even when you aren’t playing. They run in the background and yield new random numbers and seed numbers hundreds of times per second, which makes them all the less susceptible to hacking.
Number Random Generator
- RNGs ensure that every virtual roll of the dice, shuffle of the deck, and spin of the wheel is fair and random.
- Most online casino games as well as the vast majority of offline slots rely on RNGs.
- Random number generators are powered by lengthy seed numbers that can’t be cracked.
- You can count on independent auditors to regularly test RNGs for accuracy and fairness.
- Licensed online gambling sites proudly display their payout rates and test results in full view.
You don’t have to play online to encounter random number generators. The vast majority of slot machines found in pubs and live casinos use RNG microchips. Unlike vintage games which relied on players to pull a lever that would set the reels into random motion, contemporary slots use software to generate random numbers that instruct the reels where to stop. Even games that appear to be mechanical, likely have a microchip at their core.
When you log on to a licensed gambling site, you can assume that the software is fair. Yet there will always be at least a few sceptics out there. That’s one of the reasons why many online casinos now offer live dealer games. Unlike traditional internet casino games, which are essentially video games that you can play for real money, live dealer games use human croupiers and a real roulette wheel, cards, or dice. When you play a live dealer game, the gambling site will stream a table from a dedicated studio or the floor of a casino to your computer. It’s the closest thing to being there and you can even chat with the croupier.

How can a computer generate a random number?

How does a slot machine really work?
Random number generation is a tricky subject once you understand that computers are programmed by humans and merely follow the orders they receive. Fortunately, mathematicians have created a workaround. RNGs use a seed number in conjunction with a complex computer program to create a new random number. Next, that new random number becomes the seed that gives rise to the next random number and so on and so forth.
How fair is a random number generator?
Random number generators are generally fair, but it is technically possible to crack the code if you had access to the seed number, which is heavily guarded. Of course, if you could crack the code, you would be able to outsmart the casino. More importantly, casinos are required to have their software and RNGs inspected by accredited third party auditors. Look for up to date certificates from eCOGRA, TST, GLI, and other reputable agencies on the casino landing page.
Does a Random Number Generator make it easier to win on slots?
Random number generators work behind the scenes to approximate the mechanical reels that were popular decades ago. Casinos or game developers ensure that the RNGs are in line with the posted payouts over the long haul. As a slot machine player, you can improve your odds by playing games that are programmed to return the most cash back to players. Make sure that you don’t fall into the trap of believing you can predict the future based on what happened in the past. You should never assume that a game is due to pay out just because it’s been a long while.
What is the most common random number?
When humans are asked to choose a random two-digit number, 17 and 37 are considered to be the most common choices. Of course, any good random number generator shouldn’t have common numbers, as the whole point of an RNG is to create number sequences that can’t be predicted any better than chance would allow. Fortunately, the most common casino RNGs use numbers with 219,937 digits.
