Random Number Generator Online Casino
The online casinos use the so-called Pseudo Random Number Generator which operates according to an algorithm and a seed number. What sets this system apart from the rest of the available types is that it doesn’t require any external data in order to work.

For a limited time, you have to select a box to reveal your winning amount. There are many regulations and rules for this promotion so interested players should check the. Online Casino Random Number Generators Also known as an RNG for short, the random number generators used at online casinos are a key component of the operation. If you want to understand how randomization works, then you can start at the beginning and work forward to the methods used in present day games. A random number generator (RNG) is a physical or computational device that is designed to create a sequence of numbers that don't follow a set pattern e.g. Distribute randomly. RNGs are typically used for slot machines in casinos, they are designed with a microprocessor built in, which generates numbers to correspond with the symbols on that specific slot machine reel.
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.
Part 1 – Random Online Casinos
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.
Random number generators (RNGs) are crucial to the online gaming industry. In fact, RNGs are the heartbeat of the entire business and without them online casinos simply wouldn’t be fair, or fun places to play. At land-based venues, dealers randomise the cards by shuffling them. This can either be done using a single deck after every hand or, for games like blackjack, by loading a casino shoe with up to eight decks of pre-shuffled playing cards. At random number generator casinos, shuffling is replaced by a mathematical formula to ensure every card dealt, dice rolled, or wheel spun is completely random and therefore unpredictable.

What Is an RNG and How Does It Work?
Traditionally, if you needed a random number you would use a method similar to what you see in a land-based casino; drawing cards, rolling dice, or even flipping coins. Lotteries and bingo games are essentially rustic RNGs too. As the need for larger quantities of random numbers became more urgent in statistics, computerised RNGs were developed. RNG casinos use what is known as a pseudorandom number generator (PRNG). The algorithm can create long strings of random numbers automatically, but the entire series is determined by a fixed number, called a seed. By manipulating this seed, developers can control the return to player rates of online casino games.
As you can see from the image above, this whole process of creating random numbers to generate fair outcomes is quite complex. Achieving ‘true’ randomness is very difficult, but with modern technology and computer systems, mathematicians and statisticians have gotten close enough for us to enjoy fair casino games without concern.
Why Is RNG Gaming Used at Online Casinos?
RNGs originally came into the casino business as a new way to run slot machines. In the past, slots used psychical reels to determine which symbols would land on (what was usually just a single) payline, to create winning combinations. Today, online slots are complicated and can be played over several paylines. Old-fashioned cogs and reels simply couldn’t handle this kind of complexity, and thus, without the birth of the RNG we would never have reached this point in online slots.
Aside from allowing developers to create more interesting, varied slot games, RNGs are essential for making games fair and honest. Imagine you are sitting in front of a slot game online. From the
minute the game loaded, it has been creating a string of random numbers behind the scenes. The sequence is constantly moving, and won’t stop until you hit the spin button. At this point, the sequence will be halted, and the random number is converted into a tangible outcome – reels coming to a stop, a card being dealt, the winning pocket on a roulette wheel etc. RNGs are tested by independent regulators, and casino sites will not be granted an operating licence if they fail these tests.
Can You Cheat an Online RNG?
The short answer is that, in theory at least, yes. RNGs are computerised algorithms, and therefore can theoretically be hacked. In practice, this is extremely difficult, bordering on impossible for 99% of online casino players. There was an incident in 2008 where a player named Ron Harris developed a program that could predict the result of an RNG, and he won a lot of money playing Keno as result, but he also ended up in prison for his efforts. Today, online casinos are tested regularly for fairness and the authenticity of their RNGs are thoroughly regulated. Unfair or hackable systems almost never slip through the net in the modern day online gambling industry. Let’s have a look at some of the UK’s testing agencies.
TST: Testing for iGaming and Beyond
TST is well-known in the iGaming industry for its technical audits of RNGs and other lottery and sportsbook operations. It also audits poker systems tests for vulnerability to hacking as well as full-scale security tests. The TST company has offices in Italy, London, Macau, Manila, The Netherlands and Vancouver, Canada.
eCOGRA – UK’s Trusted Auditor
As one of the biggest names in the business, it’s likely you have seen the eCOGRA logo peppered around the websites of your favourite online casinos. The London-based company is committed to fair gaming and responsible conduct by operators. Aside from looking into RNGs, its test measure casinos against its own generally accepted practice guidelines to make sure everything is in order before giving it the stamp of approval.
Verisign: A Forbes Favourite
Verisign is a global leader in technical audits for RNGs and the iGaming industry in general. The company, based in North America but with offices in India, China, Switzerland, Australia and the UK, offers a range of security services and is an expert in cyber-attacks. Any casino baring its seal can be assured its RNG is in safe hands.
Gaming Associates – Gaming Safety since 1990
Gaming Associates (GA) is a leading consultant to the iGaming industry on issues regarding regulations, security and fairness. Since the 1990s, when gambling regulations really ramped up, the need for expert advice on compliance has risen. GA works with operators to ensure they are legal, and to be legal, they need to have safe, fair RNGs.
Which Online Games Use RNGs?
All modern online casino games use RNGs to provide the luck element of their games. Since we moved into digitally rendered, software-based versions of slots, blackjack, roulette and everything else an RNG casino offers, the games have used numbers to determine their outcomes. The way this works is quite simple. The RNG works in in tandem with casino software to produce fair outcomes. If you are playing blackjack, the second you hit deal the RNG will feed the software a unique value. This value is essentially the result of the hand. In our example of blackjack, that means the order of all the cards dealt in that hand are pre-determined and random. In a game of roulette, the RNG value is converted into a winning number on the roulette wheel. And when it comes to slots, the RNG dictates the outcome of every single spin. Below are our favourite slot games where you can try this principle on your own.

After playing a few rounds for free, you’ll see that all games can be boiled down the RNG – and the rest is just decoration. The software creates the cards or paylines, provides us with gameplay actions and decision, and, of course, it’s the RNG that ultimately decides if we win or lose.
How About Live Casino Games?
Liver dealer games have risen in popularity over the last five years and are worth looking at as these games diverge significantly from the RNG gaming we have come so accustomed to. Live games use real human dealers and croupiers, real cards and real tables. Thus, it’s impossible for RNGs to be used to create fair outcomes. Instead,live games use the same techniques as land-based casinos to ensure the result or each round of play is random.
However, to prevent card counting and other exploitative strategies, live card games use a freshly shuffled deck of cards for each hand. The results of live games are still ‘random’, of course, but they are not quite as random as a true RNG. Still, for the average player, you won’t notice a difference. Some live providers, such as Evolution, reassure players of fairness by using multiple camera angles in the name of transparency. Live dealer games are also considered when an auditor assess the fairness and authenticity of an casino site, so anything with a valid licence and a legal audit certificate is safe and secure.

Should RNGs Change My Playing Strategy?
If you are using a card counting strategy, then you should definitely scrap it if you’re playing online casino games. Counting theories rely on a pre-shuffled deck being used to completion in order to be able to predict the ‘value’ of all of the remaining cards by keeping a mental record of everything that has previously been dealt and is therefore ‘known’. RNG games do not work in this way. Every single hand is completely randomised, making counting strategies redundant.
Betting pattern strategies for roulette, such as martingale, can still be used in an RNG casino online, as they do not rely on measuring how hot or cold a table is. Betting strategies instead rely on mathematical principle and therefore a truly random result generated by an RNG is actually beneficial to the system.
How Does the RNG Affect the RTP?
Here’s where the seed comes in. RNGs are programmed to pick certain combinations of numbers to achieve a consistent return to player (RTP) rate. As of September 2016, online casinos are required to monitor the actual RTP of its games to make sure the RNG is not faulty. This is done by dividing the total value of all payouts of a machine or game by the total turnover it has accrued. The result should be as close to the theoretical RTP as possible. If it isn’t, then the RNG is reviewed and tweaked.
As the machines are constantly creating numbers, the timing of pressing the spin button on a slot machine changes the outcome of that round. Of course, the outcome is still random, so there is no skill involved, but a split second could be the difference between a big win or a loss. Over time, these machines pay at certain rates due to the probability of certain numbers cropping up. This is why it’s called a ‘theoretical RTP’. True RTPs are also often published by operators. The best online casinos use RNGs where these two numbers are identical.
RNG Gaming – Conclusion
Number Random Generator
RNG technology has been not allowed online casino gaming to be realised, but it made casino gaming a fairer practice. Once the restrictions shuffling cards of moving-part machines are taken away, game-makers can truly get creative with designs, safe in the knowledge that RNGs mean that a random, unpredictable result can be applied to almost anything.
