The Banned Roulette System

Is there a banned roulette system that wins so much that casinos won’t tolerate the player? Actually yes, there are quite a few. To see the top 5 roulette systems that a casino may ban you for using, visit Generally the term used for a roulette system that works is called an advantage play system. The term advantage play is not necessarily reserved for roulette, and is used by casino staff to define a system or strategy that provides the player with a legitimate advantage, hence the name advantage play.

Which are the banned roulette systems?

Before learning how to play roulette professionally, understand there’s a difference between casino cheating and advantage play. Cheating is any approach or method that is against the law. Casino rules and law are different things. For example, a casino may forbid the use of electronic prediction devices such as roulette computers. But the law may not state that electronic devices are illegal. Perhaps a law may only state that no method or technology may be used to force casino game outcomes. In such a case, the roulette computer would be illegal to apply although the casino specifically forbids them. This means that the casino can ban you if they catch you using a computer, but that’s all that can happen. You can’t be charged for a crime when there is no law that forbids your behavior.

Can you be banned just for winning?

Most casinos are private property, and the casino staff can ban you for any reason they like. They don’t need to give you reasons. But if the casino is owned by the government, typically they can’t ban you unless you are breaking the law. There are many cases I could refer to, but one that stands out is a group of roulette wheel bias players that played in Spain.

Essentially they determined physical flaws in roulette wheels to find which numbers are most likely to spin. They were not breaking any rules or laws, and the casino knew they had no legal excuse to ban them. Before attempting to ban the players, first the casino tried applying countermeasures, which are designed to make the players lose. Unfortunately for the casino, the countermeasures not work, and the players continued to win. Eventually the casino was forced to ban the players and forcibly remove them. The players won a court case which forbid the casinos from banning the players. However, the players became so well-known that the casino was able to track their behavior, and apply more effective countermeasures. All the casino needed to do was regularly change their wheels and parts of the wheels, which made analysis for roulette wheel bias impractical. For example, a wheel bias may be attributed to the rotor, which is the spinning part of the wheel. On many wheels, they look identical to that of other wheels. Now if a casino changes the rotor between different wheels, the professional team has no idea if the same rotor was being used as yesterday. Of course they could analyse thousands of spins to see if a physical bias still exists. But before they collect all spins, the casino could easily change the rotor again. So basically in this case, although the casino couldn’t legally ban the players, they didn’t need to. All they needed to do was apply increasingly effective countermeasures that make the players lose, or at least make their system impractical.

Is there a roulette system that wins no matter what casinos do?

The casino has the ability to do just about anything they want. If a player is winning large sums, the casino can easily close any wheel that the player bet at. But this is not without consequence, because a closed table means other players won’t be able to play. This is just one example, but with modern day advantage play techniques for roulette, a casino cannot apply countermeasures without risking lost revenue from normal players.

I’ll give another example. In about half of the world’s casinos, roulette computer devices are legal. They can be considered the most common banned roulette system, although they’re actually a cheating device. These are electronic devices that time the roulette wheel and ball to predict the winning number. A well-designed roulette computer can beat just about any roulette wheel design. But to use them, the player needs to take the timings of the rotor and ball just after the ball has been released. Then the player receives a prediction, and they have a short time in which to make their bets. Most casinos do allow best to be placed after the ball is released, and this makes them vulnerable to roulette computer teams. The reason that casinos allow late betting is because it means more players place bets on the table, and more players lose. So late betting overall increases the casino’s revenue. The only time the average casino will stop late betting is when they suspect a player is using a roulette computer. The change to the normal procedures will only occur until the suspected player either starts to lose or leaves. Then the casino can resume normal procedures to maximise their revenue.


Most people with no real knowledge of winning roulette will assume you cannot beat roulette. But the fact is there are many legitimately effective systems and techniques that beat the casino at their own game. Winning is not the real problem – it is avoiding detection, but I’ll explain that later. The real professionals in the industry that assist casinos to detect professional players understand the new and more effective strategies are being developed by professional teams. It is a constant cat and mouse game where the players find a new way to win, and the casino consultants and their staff find new ways to limit losses for casinos. Is there any way for casinos to completely stop consistent winners? Arguably yes, but again realistically it comes at a cost of reducing the casino’s overall revenue.

Realistically, at least in the foreseeable future, professional roulette players will continue to exist. But also casinos are getting smarter, and roulette wheel designs are improving to reduce the predictability of spins. This means that winning roulette is becoming increasingly difficult. Considering all factors, roulette is still likely to be a viable and practical income source for some time to come. This is because even today’s best technology is quite beatable with the right technology and strategies. In my experience, any roulette wheel can be beaten one way or another. It’s more a question of practicality and the amount of time it takes.

One of the notoriously difficult wheels to beat is the slingshot wheel by Cammegh. Generally this type of wheel is very well designed and to a large degree randomises the winning number. In my experience, approximately 10 to 20% of these wheels can be beaten at least in a practical way. However, the edge may be only very small such as 2 to 5%. By some standards, this may still be large considering blackjack card counting players get excited over a 1% edge. Some of my recent developments involved a careful study of the slingshot wheels, and I found an anomaly that can be exploited to increase the predictability of the spins. This has now been incorporated into new algorithms for my Hybrid roulette computer. It uses a very rare anomaly that is usually only seen with the slingshot wheel, or at least similar designs. Any roulette computer using a standard algorithm will significantly lose accuracy without the updated algorithm. Depending on the individual wheel, the difference in edge can be between no edge at all, and a 50% edge.

What is the future of banned roulette systems?

Not a lot is likely to change anytime soon. Perhaps there will always be ways to beat roulette, because changes that make winning impossible ultimately reduce the overall revenue of the casino. Still the best way for a casino to protect its revenue is to monitor players for consistent winners. Everything players do is recorded with state-of-the-art surveillance video. And the casino staff a rewind and play recorded video to have at least a reasonable understanding of what the play is doing to win. They don’t need to know all the details though. For example, if the player is winning with late roulette bets, and the casino only needs to call no more bets before the ball has been released. At least until the player leaves.

It’s much like a mouse in the pantry. Every now and then, it may sneak in and steal some cheese. Sure you can set lots of traps and do all kinds of thing to completely get rid of mice. But if you had traps everywhere, your cat’s tail or even your finger may eventually get caught in the trap too. So there would be consequences of setting traps everywhere. In the case of casinos, it is losing more revenue from normal players. It is much smarter for casinos to monitor consistent winners, and only then set the traps (countermeasures).

For players, it becomes essential to avoid detection in the first place. Considering the amount of players in typical casinos, and the amount of money floating around, it becomes quite easy for well-organised professional teams doing considerable sums without ever being noticed. It’s the same case for American roulette or European, the matter where you play. All casinos read from the same book, so to speak.

The conclusion? Advantage play for roulette will be alive and well for some time to come. There will always be a banned roulette system as long as casinos don’t like to lose.
