Predicting Roulette Numbers & How Roulette Computers Work

Ah, games of chance. We’ve all fallen prey to their allure, the temptation of a big win, the excitement of not knowing. However, as much as these games have seduced us, the desire to cheat at them is equally attractive. It’s not gambling if we can predict the outcome. It’s smart investing. Thus, people have always looked into ways to tip lady luck in their favor. Today, this is a real possibility when it comes to prognosticating in what pocket will the little white ball land, thanks to the innovation of roulette computers.

Methods to Predict Roulette Numbers

Perhaps, you’re thinking, there is no way to predict the outcome of a roulette spin, it’s too random and that it involves too many factors. Nevertheless, it is physics, something proven by a 19th-century gambler, Charles Jagger, who used his engineering know-how to detect bias in a roulette wheel. Due to years of experience with textile machines, he identified that at one wheel, the ball had a higher likelihood to land on specific numbers. It did, and he earned the moniker – the man who broke the bank at Monte Carlo.

Others have attempted to manipulate the game using less sophisticated methods, such as the application of magnets, and padding pockets. Less scientific approaches, ones that rely on cunningness and trickery. Although, in more recent decades, modern devices have found an implementation in the forecast of roulette games. In the mid-1970s, a French team devised a system where they could send a pre-tampered ball into a controlled spin via a radio signal, and it would land within six numbers, with an accuracy of 90%.   

Today, the methods used have gotten far more sophisticated thanks to video technology and computer processing.

What Are Roulette Computers?

Roulette computers are devices that measure ball deceleration and bounce in an attempt to calculate the number the ball will stop on. Technically, they’ve been around since 1963, when MIT mathematics professor, Edward Thorp, created and used one with success in Las Vegas. They made headlines again in 2004 when a Hungarian woman and two Serbian friends implemented a roulette computer to clean out London’s Ritz Casino for £1.3 million.

How Roulette Computers Work

These gadgets do not interfere with the game; they are merely tools that provide an edge in guessing the result through the help of a hidden camera that feeds information to a computer. A user films the spin of the wheel and clicks a button as the ball passes a reference point. This notifies a computer equipped with image-recognition technology of the ball’s speed and timing. The player continues to press the button from multiple revolutions to supply the software with adequate data so that it can provide a precise guess. These gadgets do not work at online casinos because digital roulette games incorporate Random Number Generators, and it’s impossible to predict their behavior.

Are Roulette Computers Legal?

The waters are muddy on this issue. Many jurisdictions define cheating as using a method that influences or alters the outcome of a game. Roulette computers do not do this, so they’re legal? Right? Not exactly. Gambling laws differ, and because these devices remove the randomness of the game, some places do not allow their use. Furthermore, casinos are private businesses, which means that they have the right to decline service. According to estimates, about 60% of jurisdictions in the world forbid the use of these gadgets.

Hybrid Roulette Computer

Hybrid is the most advanced system on the market. It requires a three-player team and costs around $80,000 to license. It’s designed for high-stakes games and has capabilities such as automatic wheel and speed detection, auto-hidden camera-aiming, and accurate prediction within three seconds of ball release. Though accuracy rates vary, the typical edge is between 40 – 120%. It’s a superior product to the Remote Uber Roulette Computer or the Two-Player Uber Roulette Computer.

Roulette Computers on eBay

If you can think of a product, someone likely has it for sale on eBay. You can find virtually anything on the consumer-to-consumer sales site, and these devices are no exception. However, when searching for them, you can use the term Roulette Predictor. Don’t expect many. These are complex systems that cost thousands.

Roulette computers on Amazon

Sadly, even though Amazon has almost everything humankind needs, you won’t find a Roulette Computer on the platform. Nevertheless, many books are available on the site that can advise on the use of appropriate strategy, the mathematics behind complex bets, and how to maximize your chances when you’re at the roulette table.

Roulette Strategies vs Computers : Bonus Tips To Win

Bonus Tips To Winning at Roulette: Strategies or Computers?

Roulette table and wheel with bettors

Roulette’s among the most popular of the classic table games casinos provide. Players often dream of coming up with an approach to give themselves an edge over the house, but are mathematical strategies or computers more effective, and how do they work? Read on to find out.

Roulette Strategies

The idea of using cunning strategies to finish ahead in the casino is obviously appealing, but (perhaps excepting card counting in single deck blackjack and “advantage play”) they tend not to work. Nevertheless, here’s a look at some strategies people may adopt when playing roulette. Be aware though, this is advice for “gamblers”, not professional advantage players.

The Martingale system can be used in various games, and for roulette would typically be used on a black/red type bet. The player puts down a stake. If they win, they pocket the profit and play again. If they lose, they make a second bet of a similar nature and double the stake. Rinse and repeat until they finish ahead.

This sounds tempting, like it might work, for a while. The odds on losing a substantial number of 50/50 type bets (red or black in this instance) are pretty long. So most of the time you will finish ahead.

There is a downside to the Martingale strategy, however, which is that it’s completely insane. What you’re doing is increasing the chances of finishing ahead by a small amount. You’re also making it so that if you lose, you lose a massive amount of cash. Yes, the odds are against that happening, but if it happens you’ll lose many times your original stake. Casinos have limits placed on wagers, so even if you have infinite funds you’ll hit the ceiling sooner or later and be unable to keep doubling.

What Martingale does is make it so that the vast majority of the time you’re a tiny bit ahead, and if you get unlucky then you lose a fortune. Don’t do it.

When it comes to beating the house, online gamblers do have some opportunities not available to those in brick-and-mortar casinos. Betting using no deposit promotions, such as those from allow the possibility of winning cash without having to actually risk any. If you fancy a crack at betting for money but dislike the risk aspect, this might be the way to go. Be sure to check out the terms & conditions of these no deposit bonuses – some online casinos do not allow you to bet on roulette with a no deposit casino promo and could confiscate your winnings.

Another strategy is the D’Alembert betting system. This involves a stake increasing each time a loss is suffered. So, a losing pair of bets would see a starting stake of $1 on black or red, rising to $2 for the second bet and, when that fails, increasing to $3. If the third bet comes off, the stake declines to $2. Should the starting bet win, the stake stays at $1.

By rising through addition rather than doubling this avoids a skyrocketing stake, as can happen with Martingale. But it still means chasing losses by raising stakes. Likewise, it still entails a higher chance of finishing ahead by a small amount coupled with a low chance of losing a large sum (again, not quite as bad as the Martingale approach).

Ultimately, trying to beat a casino mathematically is always doomed to failure because the games are specifically designed to give the house an edge. The numbers aren’t on your side.

Roulette Computers

You may be wondering what roulette computers are. Essentially, they’re devices designed to predict what number will come up next, using calculations based upon the deceleration and position of the ball. Predictions are approximate but are intended to narrow the possible results substantially enough to be useful.

It’s important to understand that there’s a rough area that’s more probable where the ball will end up. This is far from 100% accuracy (which is no bad thing as you’d stand out like a sore thumb getting the number right every time). Fortunately, the rewards that can be won are significant so narrowing the field of possibilities to that extent makes finishing ahead very likely over a session.

The obvious question is: do roulette computers work? The short answer is yes. As you may have guessed, there is a but. The problem is that casinos, quite understandably, are not keen on players using devices that shift the house edge so that the players become likelier to finish ahead than behind. Get caught using such a device and you will be banned.

On legality: it’s reckoned roulette computers are legal in roughly half of casinos. It’s a matter of whether a jurisdiction views illegality by influencing outcomes (which the computer doesn’t do, it’s merely a predictor).

The computer isn’t carried about by the player. Instead, phone camera footage of the roulette wheel is sent to the computer, that sends back the necessary information to the player. Of course there are many other types too.

There is a hefty price tag, which will run you to thousands of dollars, and perhaps tens of thousands. This is not for a casual gambler.

Another potential pitfall is untrustworthy sellers. The technology is reliable, but with high price tags and the matter being discreet, it’s one that does see dubious sorts selling computers that don’t work. Be wary, including reviews which can be bought and paid for. One way to try and get around this problem is to insist on a personal demonstration on a wheel of your choice.

Strategies Vs Computers

You won’t get banned for using a strategy like Martingale, although you might get pitied by savvier gamblers.

Another advantage that a computer has over an individual using strategies is that a team of a few people can use the same computer, and cover a larger number of bets to increase even further the chances of finishing ahead.

Perhaps the telling point is that they’re banned. Card counting in blackjack is another practice that isn’t exactly welcomed by casinos (although as it’s done purely by mental arithmetic and memory it’s harder to spot outright unless the player is mumbling the count to themselves). If the casino doesn’t want you doing something that’s because it shifts the odds to your advantage.

On the convenience front, you only need internet access. You don’t have to actually go into the casino yourself, but simply have everything done remotely, with others placing bets.

It is possible to get carried away, though. Win a fortune in a short space of time and you’ll be detected pretty quickly, as the Ritz Players found out in 2004.

In essence, the difference is that strategies are free, don’t work, and casinos don’t mind you using them; computers do work, come with a price tag, and you’ll be banned if you get caught.

Whether a computer in itself is worthwhile depends a lot on how much you’re willing to bet (no point spending on one for a $10 profit), and how comfortable you are with doing something you know will get you banned (if you are caught).

Roulette Computer Myths & Facts

This article explains the common myths of roulette computers.

Myth 1: They Are Illegal.

Actually they are LEGAL in about 60% of jurisdictions. Every jurisdiction is different. Gaming law is usually state law, not national. So it can even be legal in one state, but not another – within the same country.

How can this be legal? After all, wouldn’t casinos push to make them illegal if they stand to lose money?

Many casinos have indeed lobbied to make roulette computers illegal. But the push is not as urgent or dramatic as you may think.

Basically every casino is aware of the existence of roulette computers, but they don’t fully understand them. Nor do they need to. To make roulette computers ineffective, casino staff need only close bets before the wheel is spun. It sounds like an easy solution, but this would lose the casino even more money, so they don’t do it. I’ll explain more about this later on. For now I’ll focus on the legalities.

Most gaming laws define cheating as anything that:

  1. Wins money from deception, or
  2. Influences game outcomes.

Roulette computers do neither. They merely predict spins.

It’s quite easy to check your jurisdictions gaming laws. See a list of gaming authorities.

One example of deception is placing a winning bet on the table after the ball has landed. Cheating players have one fortunes with this particular approach. It requires distracting and deceiving the dealer. Although roulette computers are hidden, the advantage they achieve has nothing to do with deception.

An example of influencing game outcomes is tampering with the wheel or ball. For example, some players have previously used discrete air blowers to influence spins. Again, roulette computers do not influence spins. They merely predict spins.

Myth 2: Casinos Will Eventually Close Betting Before Spinning The Wheel

Roulette computers can’t work if bets are closed before the wheel is spun. However, casinos know that doing this for all players ultimately loses the casino money.

This is because many players prefer betting after the ball is released. The reasons for this are varied. For example, some players believe dealers can influence the winning number, and deliberately avoid the player’s bets. This is not realistically possible, and is discussed in detail in another article here.

Additionally, by allowing players to make bets while the wheel spins, the game is sped up, and more bets are placed on the table. And since the vast majority of players do not use a roulette computer, the casino maximizes their revenue by allowing late bets. This is why almost every casino allows late betting (bets after the wheel is spun).

Casinos know that if they suspect a player of using a roulette computer, they need only close bets earlier until the player either loses or leaves. Then normal procedures can resume.

Does this mean game-over for computer players? No. A well-organised roulette computer team can easily earn large sums without ever being detected. The procedures and techniques to avoid detection are beyond the scope of this article. It’s something only disclosed to our players. It’s not difficult to earn a few thousand dollars, then leave before the casino suspects anything. A roulette computer player may only make ten or so bets before leaving with a profit.

Online casinos are a bit different. They tend to adopt a more cautious approach to the threat of roulette computers. This is why most live online roulette casinos don’t allow betting after the wheel is spun. After all, online casinos cannot physically see you, and are at a disadvantage when detecting roulette computer players.

Myth 3: The Computer Must Be Visible, or Near The Wheel.

I’m not sure why, but many people seem to believe a roulette computer must sit on or near a wheel to work. But actually they are never visible to casino staff.

Roulette computers are easy to hide. They can be hidden just about anywhere, and are never in open view of the casino staff. Usually they are hidden in a pocket.

Most roulette computers use a hidden cable with a small button on the end. The button is usually pressed by your toe as the wheel and ball complete revolutions. The time between these clicks is what establishes the wheel and ball speeds.

The button can be hidden in many different places. For example, the player can hide various hidden buttons throughout their body and clothing. If they are sitting, it might be on their knee. Or it could be on the end of the jacket sleeve.

Our most sophisticated computers don’t need hidden buttons at all. They use a hidden auto-aiming camera which transmits encrypted video through the Internet to a server. The server then analyses a video to determine wheel and ball speeds. Predicted numbers are then transmitted back to the players in the casino to bet. The player with the hidden camera could be 30 feet away from the wheel, playing on a slot machine like book of ra deluxe, never suspected of being part of an elaborate roulette computer team.

Myth 4: Casinos Can Search You And Find The Computer

If you are using a roulette computer where it is legal, casinos do not have the legal right to search or detain you. This would require the presence of law enforcement officers such as the police.

If you are playing where it is legal, it is unlikely you will ever be searched. It doesn’t mean it can’t happen though. As far as I’m aware, in the fifteen years that I’ve been operating roulette computer teams, I’ve only ever known of three teams to be caught.

The first was a lone player in an Australian casino, who won approximately $200,000 over a few months. What got him caught was staff noticing him tapping his foot. I suspect he became complacent, which is likely to happen after months of winning. He should have been using a toe switch, with the correct shoes to hide movement of his toe. Roulette computer application is illegal in Australia, so he was going to be charged. But the charges were eventually dropped, reportedly because he was a tourist, and prosecution would be “messy”.

Secondly, a group of players won £1.3 million in the London Ritz casino. The winnings were achieved over a three-day period. Casino surveillance staff suspected the players were using a roulette computer. The police were called to review footage, and the three players were detained (with no charges). Various electronic gadgets were confiscated. However, the players were not charged because they did not break any laws. Since then, the local laws were changed to make roulette computers illegal. But later the computers became legal again because of gambling deregulation. The police stated that casinos would be required to “police themselves”.

Only one of my players has ever been caught. He was applying the computer illegally in an Asian casino. He too was not charged, and was fortunately released only with a warning.

Anyway back to my original point. A typical computer is never visible to casino staff. The only way casinos will know for sure you’re using a roulette computer is if they physically search you, and your physical equipment is obvious. It would then be difficult to explain why you have a peculiar looking custom electronic device.

This is why the majority of our roulette computers are made from modified mobile phones. After all, they are the perfect disguise. You can even make phone calls on them.

Our most sophisticated roulette computer is a perfectly normal-looking mobile phone, with no additional equipment such as wireless earpieces. Furthermore, the phone can be completely encrypted, and even wiped remotely. This means that if you are physically searched, and the phone is carefully inspected by the manufacturer, absolutely nothing can be found to incriminate you.

However, although we could easily use roulette computers illegally (and never be caught), we don’t. Firstly, I personally earn enough without needing to break laws. And secondly, there are plenty of legal places to play.

Myth 5: If You Are Caught, You’ll Be Taken Out Back and Bashed.

This could happen if you are caught in an illegal underground Romanian casino run by the mob. But I have never heard of it happening. As far as I know, it has only ever happened in the movies.

The reality is if you are suspected of using a computer, all the casino does is instruct the dealer to close bets earlier. Then when you leave, normal procedures resume. This means the casino continues to allow late bets, which maximize their revenue.

Myth 6: If They Really Worked, Casinos Would Be Out Of Business

Roulette computers may be the quickest and most profitable way to beat casinos. However, there are many other legitimately effective techniques, which beat a variety of other games – not just roulette.

The most common term for such techniques is “advantage play”. Casinos are of course aware of how their games are vulnerable to professional players. This is why most casinos employ consultants, which advise their staff on how to detect and deal with professional players.

The simple fact remains that casinos know some advantage players may slip through the cracks, and remain undetected. So it is the job of the surveillance staff to detect such players before they do too much damage. Therefore it’s not so simple for players to walk up to any wheel and win millions. The chances are you will be detected before winning millions. And then the casino need only close bets earlier, until you leave.

This is why I’ve said many times beating wheels is not the problem. The real problem is avoiding detection. Some players have indeed won millions in short spaces of time. But this is rare. Most roulette computer players earn between $1,000 to $10,000 per session. And this is done right under the nose’s of casino staff. Consider the amount of money moving around the table. It’s not so hard to blend in. Also consider that a roulette computer player may only make ten or so bets before leaving with a profit. Then you can understand why it is not at all difficult to earn significant profit, without ever being detected.


Casinos of course know about roulette computers. But most staff only have a vague idea of how they work, and what the technology can do. Usually, everything they have learnt is from casinos consultants who are paid to educate staff. But the consultants themselves usually only have vague understanding. More specifically, they are only aware of older technology, and the basics.

One particular casino consultant said it best: “The players know more about beating the games than us. This is because they are the ones spending the most time and effort to beat the games. As long as this is the case, advantage play will be alive and well for some time.”

It doesn’t mean casinos won’t continue to protect their games. After all, no casino tolerates a consistent winner, regardless of how you win. The first and the best line of defense for any casino is vigilance surveillance, then neutralizing any threat as quickly as possible. In the case of roulette computers, it means closing bets earlier until the player leaves.

It isn’t so simple to make roulette impossible to beat with a roulette computer. It’s actually far more difficult to develop a truly unpredictable wheel, than it is to achieve sufficient accuracy with a computer. In a separate article, I will discuss the various technology casinos and wheel manufacturers have used in attempt to neutralize the roulette computer threat. Essentially their best technology, while very rare, does least reduce the effectiveness of roulette computers (usually halves the edge, which is still ok for computer players). But the downside is it ultimately loses the casino revenue, because players feel the spins are being manipulated, don’t trust the wheel, and inevitably don’t play. This is why such technology is not widely used by casinos (it ends up costing the casino even more).
