The Top 5 Roulette Systems That Can Earn You a Living at Real & Online Casinos

The no-nonsense guide to beating roulette. What works, what fails and why. Download FREE roulette systems that still work in today’s casinos.

Roulette is not the unbeatable game that most people think. But there are only a few approaches that actually work, and all are explained on this site. If you are tired of the rubbish written by people with no real experience and want the real facts about winning roulette, this is the site you’re looking for. Learn about the most popular professional roulette system.

Why Most Systems Eventually Lose

Losing roulette playerThe casino has an in-built advantage called the “house edge”. For example, a bet on number has a 1 in 37 chance of winning, but a win pays only 35 to 1. So even when you win, you still lose because the payout is unfair. Over time, the unfair payouts erode your bankroll. It’s much the same for other roulette bets. You can only overcome this by predicting winning numbers with better than 1 in 35 accuracy. In other words you must consider why the ball lands where it does, and predict future spins.

However, most roulette systems don’t even consider the “accuracy of predictions”. Most use ineffective and roundabout calculations based on patterns that only appear in old spins. Such systems neglect the real physical factors that determine the winning number.

Approaches That Don’t Work:

Betting progression: This is when you increase the bets to cover losses. It doesn’t work because every spin is independent, and when you change bet size, you are only changing the amount you bet on an individual spin. At first it’s hard to understand this concept because you may be stuck thinking “a good win will get back the losses”.

Thinking numbers are “due”: Nothing is ever “due” to happen. Even after 10 reds in a row, the odds of red or black spinning next are no different. If you don’t believe this, check records of thousands of spins and look for instances where 10 reds spin in a row, then check the amount of times red or black spins next. You’ll find the odds haven’t changed.

There are many other common misconceptions and ineffective approaches. Ultimately you can only beat roulette by increasing the accuracy of your predictions. How accurate do you need to be? . . . Well keep in mind the house edge is a small -2.7% so you only need to have slightly better than random accuracy. And this is quite easy to do.

What Does Work?

Anyone who says roulette can’t be beaten doesn’t know what they’re talking about. Roulette is being beaten every day, and in fact most casinos hire consultants to help them detect professional roulette players. Historically the only roulette systems that have consistently beaten roulette involve physics. That’s because the winning number is determined by a wheel and ball, and physics is the only science that can model and predict their behaviour. Sounds logical, right? Below are the top 5 methods that work:


Ranked 5th: Bias Analysis (exploiting wheel imperfections)

Roulette wheels have slight imperfections that make some numbers win more than others. This is called a “biased wheel”, and all wheels are biased to some degree. You may have heard of the “man who broke the bank at Monte Carlo”. His name was Joseph Jagger, and he won a fortune after discovering roulette wheels were biased. This approach to beating roulette has cost the casinos many millions. See the video below about a different team that won around $1M starting from only $2000:

Do biased wheels exist today? Certainly yes, although casinos monitor spin results and quickly replace any significantly biased wheels. However, the software casinos use to monitor their wheels require around 10,000 spins to analyze. The good news is advanced techniques can spot a bias in far fewer spins. This means you you find and profit from a biased wheel before the casino even knows about it.

  • Find and profit from biased wheels before casinos know about them
  • Get predictions before the ball is released


  • Beats only 2% of today’s wheels
  • Takes more time than other methods
  • Easy for casinos to notice your style of play
  • Casinos can move wheels if they detect you


Ranked 4th: Dealer Signature (consistent spinning dealers)

Many dealers tend to spin the wheel and ball at consistent speeds. This can lead to predictable patterns called “dealer signature”, which is why dealers are usually changed every 20-30 minutes. However, dealer signature doesn’t work on every wheel. You need the right combination of dealer and wheel.

Wheel dominant diamondThe principles are very simple. Firstly, consider that on most wheels, the ball will tend to hit some metal deflectors (diamonds) more often than others. These are called “dominant diamonds”. If you drew a chart showing which diamonds the ball hits, it would look like the image shown left.

Secondly, consider that the ball bounce is never completely unpredictable. For example, if you see where the ball hits the wheel (rotor), you can guess approximately where the ball will land. You wont have perfect accuracy, but you don’t need perfect accuracy.

Now say the wheel was always much the same speed, and the ball always did around 10 revolutions before hitting the dominant diamond. This means that the ball would be travelling a predictable distance, be falling in a predictable area, then bouncing a predictable distance.

Putting this all together, dealer signature requires you to first find suitable wheels. Then you need to find a suitable dealer for that wheel. There’s nothing difficult about it, and although it works, it has limitations.

  • Easy to use once you identify suitable wheel & dealer
  • Get predictions before the ball is released


  • Beats only 3% of today’s wheels
  • Time consuming to find suitable conditions
  • Easy for casino to change factors to make you lose
  • Slight changes in air pressure can cause patterns to change (even with same dealer)


Ranked 3rd: Visual Ballistics (using eyesight to predict winning numbers)

This technique uses your plain eyesight to estimate where the ball will fall. It’s not as difficult as you may think. In fact it’s quite easy.

Visual ballistics is very similar to dealer signature, except you predict the winning number near the end of the spin instead. For example, you make your prediction when there are about 5 ball revolutions remaining.

You can learn a simple visual ballistics system for free below:



  • Relatively quick to use
  • Requires 60 – 100 spins to evaluate each wheel


  • Requires late bets (after ball release)
  • Beats only 3% of today’s wheels
  • Easy for casino to notice your consistent behaviour


Ranked 2nd: JAA Cross Referencing (most popular professional system)

This is the most effective system that predicts winning numbers before the ball is released.

This method finds the relationship between the physical variables of the wheel, and the winning numbers. Basically it models “cause and effect”. After all, the winning number is never actually “random” – it’s due to physical variables such as the ball and wheel. Predicting the next winning number is more a matter of knowing how the variables affect the winning number. More importantly, the method allows you to predict winning numbers even when the variables are different (including when the dealer changes, or if the ball and wheel speeds are varied).

Ranked 1st: Roulette Computers (electronic cheating devices)

These are hidden electronic devices that measure the speed of the wheel and ball to predict the winning number. They are the most effective way to beat roulette, and are legal in approximately half of casinos. However, casinos can still ban you for using them, so they must be used discretely to avoid detection.

Is It Really Possible To Beat Roulette?

Real players beat it every day. You just don’t normally hear about it because 99.99% of players lose. But sometimes big wins make the news like the ones above. So of course casinos know all about it, but they understandably want to keep it low profile. But as long as the vast majority of roulette players lose, roulette will always be a profitable game for casinos.

Generally casino staff view professional players more as a nuisance than a serious threat. They know you can win a lot very quickly, but they rely mostly on detecting you before winning too much.

There are various steps casinos can take to make winning more difficult. But this tends to slow down the game and make spins less frequent. This ultimately loses the casino money because less frequent spins means less money wagered, and less revenue for them. So casinos rely more on detection of consistent winners than making winning impossible. If you are detected, the casino staff temporarily change procedures to make winning more difficult. For example, the dealer may call “no more bets” earlier, which makes techniques like visual ballistics ineffective. Then once you leave, normal procedure can resume. You can still sneak back in later.

But if you don’t get greedy by winning too much too soon, you can earn substantial profits without being detected.

How To Know If Your Casinos Wheels Can Be Beaten

The two simple tests below can determine how easily beaten your casino’s wheels are:

Wheel dominant diamondTest 1: Dominant Diamonds

Create a chart like the one shown right (for each direction), and place a dot next to each diamond the ball hits. You’ll find most wheels have particular diamonds that the ball hits most. The more dominant the diamond hits, the more predictable the wheel, although wheels can still be beaten even if there aren’t any dominant diamonds.

Predictable ball bounceTest 2: Predictable Ball Bounce

Observe how far the ball bounces after first hitting the wheel rotor. Measure the distance in pockets, and you’ll find that the ball bounces a predictable distance. The chart right shows typical results.

When you combine these two factors, you’ll see that where the ball first falls, and where it bounces is quite predictable. In fact it’s virtually impossible to have a roulette wheel with completely unpredictable spins. Remember that the house edge is only small (-2.7%) but it earns casinos millions. You only need slight accuracy to have an edge at roulette. This is why the casinos know their best defence is detecting consistent winners, but it’s easy for you to win $1,000+ per session without being detected.

Which System Is Best For You?

Most of the methods above are provided free. But the more powerful cross reference (JAA) and roulette computers are available only to purchasers. The roulette computers are the quickest and most profitable option, and are still legal in about half of casinos (mostly Europe). But legal or not, you can still be banned from casinos if caught using them. They can be used at some online casinos.

Most people prefer the cross reference system (JAA) because it is legal everywhere and can be used on a broad range of wheels, including wheels at many online casinos and automated wheels (where the ball is released automatically). It is very simple to use because automated software does the sophisticated analysis for you, and it gives you convenient betting charts that tell you when and where to bet.
