Roulette Analysis

Welcome to Roulette Analysis

Roulette Analysis App
Our roulette analysis App is a professional tool. The software analyses the results of spins in a roulette game. In the case of real wheels the software exposes any sector bias that may be present. In the case of animations, based upon pseudo random number generators, the software identifies repeating patterns. The object being to gain an edge over the casino.

New in Version 2.0
This Version of our Roulette Analysis App builds on version 1.0 with a few new features. Version 1.0 concentrated on the analysis of real wheels and identified sector bias. Version 2.0 does the same but now includes powerful statistical analysis applicable to on-line animated games which use computer generated pseudo random number generators. You can now record up to 2000 spins in one session. The analysis algorithm continues to be developed and improved. In the case of the Iphone/Ipad, the user interface has been changed. Errors in the last 10 spins can now be corrected. You no longer need to be connected to the internet to display wheel bias graphically. The bias graph is generated on the Iphone so the app is now completely portable to any casino. The Mac/Pc version has been changed in the same way but includes the archiving feature whereas the Iphone/Ipad version does not.

Roulette Wheel Analysis - What's it all about ?
Traditional roulette games are played in real casinos using real wheels and real croupiers. Real wheels are mechanical devices that are supposed to be "fair". A fair wheel will, over time, result in every number from 0 to 36 appearing with a probability of 1 in 36. This means that over time the odds that a single number will appear is 36 to 1. The problem for the punter is that even given a fair wheel, the payout is actually 35 to 1. This gives the casino an edge and in the long run the casino can't lose. These odds are made even worse for a punter using an American wheel. American wheels have 00 as well as 0, so the odds are even more in favour of the casino.


In recent times casinos, and other organisations, have seized the opportunity to take the roulette game on-line. The transition started with the development of computer software that mimics a roulette table as an animation. They even created sounds that mimic the noise of a spinning ball and the noise made when it dropped into a slot. This is nonsense of course. The roulette table animation could simply by replaced with a box. The random number just appears in the box. This has nothing to do with the real game of roulette.

A variation of the online game came when pneumatic wheels were developed. The wheel is spun automatically at regular intervals and the ball propelled by a blast of air. This mechanism could be on-line 24/7 without the expense of a real person.

Yet another variation was the web cam in a real casino. The web cam, with sound, gives a sense of the atmosphere in the casino with real croupiers and punters placing bets. Online bets are synchronised with the game at the table. The best example of this is Some organisations broadcast on terrestrial TV. A real person is on hand to spin the wheel but bets are placed online. The table is located in a TV studio rather than a real casino.

To sum up you have 3 choices. Either a real wheel spun automatically A real wheel in a studio or real casino spun by a real person or an animation and computer generated pseudo random number.

Roulette Systems
The only guaranteed system is the Martindale system. This system is very simple. You make an evens bet and if you lose you double your bet. So if you bet red and you win, you double your money. If you lose you repeat the bet with double the stake. If you win you get back your original stake and you are back to square one. If you lose you keep doubling up until you are guaranteed to eventually win and get your stake back. The only draw back is that you have to keep doubling your bet. The stake can become astronomical very quickly. On a run of reds for example you could be staking thousands of dollars in order to get back where you started. However you are guaranteed to get back where you started but only in a game which allows unlimited bets. The Martindale system was shut down a long time ago by casinos by placing betting limits. If you are on a table with a limit of say $500 and play Martnidale you are guaranteed to lose all your money sooner rather than later.


The layout of the roulette table is designed quite specifically to deceive the punter. The layout of numbers on the roulette table bares no relation to the layout on the actual wheel. The casino gives the impression that there is any meaning to the term 1st dozen, odds, streets etc. Any bets based upon these groupings are no more that a random selection of numbers. Any system that's based upon such groupings has no meaning whatsoever.


How can the punter win in the long run ?
The punter can only get an edge over the casino by identifying weaknesses in the apparatus and then exploiting that weakness.

Lets consider firstly a real wheel.

The only way to win is to get an edge over the casino. In other words beat the fixed odds over the long term. This can only be done by analysing the wheel in order to predict with accuracy which slot the ball is going to land in next. Slots on a roulette wheel have nothing whatever to do with numbers. They are positions in space on a wheel. The wheel has fixed mechanical characteristics. For example: the diameter of the wheel is known, the distance between slots is known. If every mechanical parameter about the wheel is known, the application of Newton's laws of motion would allow you to calculate, with certainty, where the ball will land next. Just as Newton's laws predict the motion of the planets.

Such wheel analysis goes back many years. There are stories of clever individuals timing the speed of the wheel and doing calculations based upon the wheels dimensions etc. Of course this was in real casinos and it didn't take long for the casino owners to become wise to this practice. They ejected anyone suspected of being a wheel analyser. The one thing wheel analysers were looking for was a fixed wheel. A fixed wheel is one that displays a bias towards one sector of the wheel. If a wheel analyser could identify a biased wheel they simply bet on the sector and thats how they gained an edge on the casino and won in the long run.

It may be wrong to suggest that casinos deliberately fixed wheels but in the early days mechanical engineering was not as accurate as now. With the technology available then it would have been common for a wheel to be naturally biased. Casinos deploy a number of techniques to thwart real wheel analysers: hazards are a placed in the path of the ball on the wheel surface, croupiers are changed at regular intervals, the ball is spun clockwise then anti-clockwise, the frame that displays the numbers on the wheel is moved around, wheels are moved from one table to another when the casino is closed.

We must emphasis that analysing a real roulette wheel is a complex task. You will need to record many sessions at a particular wheel in order to identify a definite fixed biased there. If you do find such a wheel then you will make some winnings. A repeating bias pattern is the holy grail of real wheel analysis and is hard to find.

Casinos go to great lengths to ensure that the result of the next spin is a truly random event.

What about on-line games that use animations ?

As we have said before, these games have nothing to do with real roulette. They simply display the results from a pseudo random number generator. Pseudo random number generators are pieces of computer program that generate random numbers. The key word here is 'pseudo' because they are not pure random number generators at all but are inevitably based upon deterministic algorithms. Of course there is no concept of sector bias because there is no wheel. However the weakness lies in repeating patterns. If you can identify repeating patterns of behaviour then these can be exploited. Pseudo random number generators can get stuck in patterns. The most common one is repeating numbers.

On-line games using auto wheels

The auto wheel presents a good opportunity for the punter. Unlike a real wheel, operated by a human being, the auto wheel has a predictable pattern of behaviour. If you watch an auto wheel carefully you will notice that the wheel spins at the same speed, the ball always starts from the last winning slot and is spun alternately clockwise then anti-clockwise. These are predictable initial conditions. The only randomness in the system is created by the hazards in the ball's path.

Which game should you play ?

This is difficult as each format has it's own weaknesses. One thing has become clear though. The initial enthusiasm for on-line computer animation and pseudo random numbers has given way recently to real wheels with real croupiers. There is a reason for this. The traditional roulette wheel (assuming it's fair) with a human operator, is the best random number generator. We have analysed hundreds of sessions from different online casinos and we have come to the same conclusion. The casino has the best chance of winning if the wheel is truly random.

Having said that if our software reveals that a real wheel is very random then a statistical bet based upon vacant numbers could give you an edge. If the weel is displaying transient sector bias it's probably not a good idea to bet on it.

There is also another reason for not choosing to bet on real wheels - it's a slow process. This is especially true if the online casino is broadcasting on television at the same time. These television shows are a waste of time. However it's worthwhile spending time analysing the wheels as you may find one that does have a bias. If you prefer to bet on real wheels the auto wheel may be the best choice because they are more deterministic and the game moves more quickly.

One thing to keep in mind though is the location of the wheel. If the wheel is in a studio it's easy for the casino to switch wheels. You would not be aware of this. Your analysis of the wheel is useless if the wheel was switched. The only way to guarantee that you are analysing the same wheel is to be in a real casino or to be watching a web cam of a real casino.

We have analysed hundreds of sessions and our conclusion is that the online game which uses a computer animation and a pseudo random number generator is the best option.

We have come to this conclusion for a number of reasons. You have to think about your objective. The objective is to win as much money as possible in the shortest possible time - not to play the game of roulette. The rapid turn around of spins in these games works in your favour because you have to record the results of many spins before you can identify any pattern. In a real casino with a real wheel this could take hours.

This is a factor we haven't mentioned yet - the time involved in analysing a wheel. Wheel analysis is only practical using a computer and in order to identify any bias or patterns you need to analyse many spins and many sessions. A real casino would not allow you to use a computer at a roulette table but there is nothing to stop you writing down results and using a laptop in a quiet corner. Our software is ideal for this and the Iphone version could be used at a table without raising any suspicion. In reality it's most likely that you would be playing an online game in the comfort of your own home.

How can the punter win in the long run ?
Assuming that you have recorded many sessions at the same wheel you may find that a regular pattern becomes clear. In the case of a real wheel, our software identifies the same wining sector in each session. Certain numbers appear more often than others in the case of an animation. This is called a permanent bias and is caused by a fixed or faulty wheel or a random number generator with a software bug. In this case you have found a sure bet and could win a lot of money.

Our research has clearly demonstrated that real wheels and pseudo random number generators can get stuck in transient patterns. This is not uncommon in random systems in nature. These patterns can last quite a long time in a session. Our software identifies these transient effects. We use a mathematical technique known as 'linear regression'. Linear regression is a way of predicting trends in apparently random data.

How does our software help ?
Set Analysis
The software makes three sets of predictions. Repeating numbers, Vacant numbers and Sector bias. The sector bias is calculated from the beginning of the session so every result is included in the calculation. If the bias remains fixed on a particular sector for hundreds of spins and is always the same every time you analyse the same wheel then you have a real winner – no doubt a doctored wheel or in the case of an animation, hacked software.
Repeating Numbers
This set of numbers contains all those numbers that don't appear in the list of vacant numbers. It's impossible to predict repeating numbers directly because there is no clear reason for picking one number that has appeared 10 times over one that has appeared 6 times.
Vacant Numbers
This set of numbers contains all those numbers that have not appeared at all. This calculation cannot be done from the start of the session because a point will be reached when every number has appeared at least once. The calculation therefore is based upon a moving window. When all the numbers have appeared, the window shifts in the result history to the point where 18 vacant numbers can be identified. The reset point is determined by the number in the “Reset at” box. We have found that the optimum reset point is when there are 5 numbers left in the prediction. This is especially true if you are analysing an animation.
As you enter more and more results you will see the bank increasing or decreasing as each prediction yields either a win or a lose. This value will fluctuate but over time a trend will occur. This trend can be used to help you chose whether to bet or not. The trend is calculated by a mathematical process known as “linear regression”. This is a powerful tool used extensively to predict future outcomes based upon seemingly random data. The software does two trend calculations. The left hand one is the trend from the start of the session. The right hand one is the trend over the last 10 results. A strong and sustained positive trend in both values is a good indicator.
Bias Graphs
To help you visualise any bias in the wheel we present the data graphically. The graph displays data in different ways which depend upon the “wheel type”. If this is set to “real wheel” the graph shows the predicted sector. If it is set to “animation” the graph shows the actual number of times each number has appeared. If the wheel is perfectly random and a large number of spins have been recorded the graph will look irregular and will not display any significant peaks or troughs. If your graph looks like this after about 100 spins then walk away. There is no point betting on a truly random wheel as the statistics are always in favour of the casino. If on the other hand the graph shows a distinct peak then the wheel is exhibiting a bias towards that sector or a particular number.
You can enter up to 2000 results for a given session.
We have analysed hundreds of sessions from different wheels and different online games. Most real wheels display a bias towards one sector or another and animations based on computer pseudo random generators tend to produce more repeated numbers. In order to maximise your chance of identifying a likely candidate the software lets you archive each session. Each archived session can be associated with a particular casino and or wheel. When you have amassed a large number of sessions you can analyse all the sessions. If you then view the bias you may see a definite trend either towards a particular number in the case of an animation or a sector in the case of a real wheel.
