Star Ratings (the "short story")

Ratings for various elements. To know why ratings are as such, you need to read this whole chart and understand the differences between devices.

Accuracy: how accurate predictions are on common modern wheels

Practicality: how practical it is to use in real casino conditions

Early predictions: how early predictions can be, while maintaining accuracy

Stealth: how difficult an experienced user is to detect for casino staff (higher rating means more difficult to detect)

	Accuracy	Practicality	Early Predictions	Stealth
Remote Hybrid (ours)
Remote Uber (ours)
Uber two-player (ours)
Uber single-player (ours)
Lite two-player (ours)
Lite 1 single-player (ours)
Basic Computer (ours)

NOTE: The differences in accuracy are more apparent on wheels that are more difficult to beat. For example: on an average modern wheel in casino conditions, the less effective computers may have no accuracy at all, whereas the more powerful computers cn achieve a 1 in 10 hit rate (one win per 10 spins if you bet only 1 number).

Furthermore, the more sophisticated computers are easier to use. For example, the Hybrid version uses a hidden camera and equipment to automatically measure wheel and ball speed, and predict the winning number. This is considerably easier and more accurate than the other computers, which rely on you clicking a small button typically hidden under your toe. The "toe switch" versions (all except Hybrid) all use sophisticated algorithms to make timing errors insignificant. The Uber and Uber Remote V2 also use manual clicks of hidden buttons, although multiple players can take timings simultaneously, which eliminates any significant timing errors.

Ultimately the more sophisticated the roulette computer, the quicker, more accurate, easier and therefore more profitable it is to use.

Hardware & General Description

Modified mobile phone: modified to ensure suitability of hardware.

Timing accuracy within 1ms.

Almost identical to the "Remote Hybrid" except ball and rotor timings are measured using clicks of a hidden button (usually in shoe). A hidden camera is not used.

Timings can be taken by 1 to 4 individuals simultaneously, to ensure virtually error-free timings. Only 1 players is needed.

Timings are transmitted via wireless Internet to the server with minimal buffering to ensure timing accuracy.

The server calculates predictions and relays them to any amount of players.

Image recognition hardware and software: aim a camera and predictions are made automatically.

Timing accuracy within 1ms.

One or more hidden cameras stream live video via wireless Internet to the Hybrid server, which calculates predictions and relays them to any amount of players.

No sensitive equipment is ever taken inside the casino. The main equipment ever taken in the casino are standard smartphones (1 per player).

Modified mobile phone: modified to ensure suitability of hardware.

Timing accuracy within 1ms.

Modified mobile phone: modified to ensure suitability of hardware.

Timing accuracy within 5ms.

Same Spin Testing

This is a simple test where the same spin on DVD is repeatedly predicted. If the computer cannot accurately process timings, the predictions will be significantly different each time.

This is not a test of prediction accuracy. It tests only the ability to deal with timing errors from the player clicking the hidden button. Basically the tighter the groupings, the better.

This testing was done by connecting all three devices to the same switch, then predicting the same spin. This way each computer received exactly the same data to process.

Same spin testing

The Hybrid computer takes automated timings with no significant errors. It processes video at 30 FPS although it detects the ball and rotor position multiple times for each revolution. This virtually eliminates timing errors. So if it predicts the same recorded spin, the prediction is the same each time.

Wheel Timings Data Acquisition:

This is how the computer knows what the wheel and ball timings are

Manual clicks (subject to human error) although it has exceptional error correction.

The 2-player version allows the second player to take timings, which halves timing errors.

Ball and rotor timings are measured using clicks of a hidden button (usually in shoe).

Timings can be taken by 1 to 4 individuals to ensure virtually error-free timings. Only 1 is needed.

Image recognition hardware & software: a hidden camera and image recognition equipment automatically determines wheel and ball speed. There is virtually no error in timings.

Manual clicks (subject to human error) with reasonable error correction

Does the computer predict which diamond will be hit, which part of the diamond will be hit, and how the ball will hit the rotor?

Most computers incorrectly assume the ball is going to hit the wheel rotor (the part with the pockets) at a point where the ball reaches a certain speed. This is incorrect because the ball may hit a vertical diamond, or a horizontal diamond, or it may not hit any diamond at all. Whatever the case, the ball's behavior is very different for each type ball fall. A computer that does not account for different types of ball falls will produce virtually random predictions on modern whee4ls. In fact this is designed to be the case for modern wheels - it is the very purpose of vertical and horizontal diamonds.

YES. It can predict which diamond will be hit, and the part of the diamond that will be hit (accurate to within 1/3rd of a diamond), and the manner in which the ball will fall (under reasonable conditions).

In other words, if the ball clips a horizontal diamond then lands on the other side of the wheel, the computer predicts this. Or if the ball misses all diamonds completely, the computer will adjust for the different type of ball fall.

NO. It assumes the ball will fall exactly the same way irrespective of whether the ball hits a vertical or horizontal diamond, or if the ball doesn't hit any diamond at all.

Accuracy Vs Wheel Tilt Charts

These charts show the accuracy of each computer with relation to wheel tilt. Only a correctly constructed computer will increase in accuracy as wheel tilt increases. This is very important because most wheels are neither tilted or level (neither perfect or heavily flawed)- they are in fact somewhere in-between which makes computer design far more complex. The green area shows the degree of tilt for most wheels. The relevance of these charts is very important to understand.

Accuracy chart

The green area shows the area for 95% of wheels. Accuracy increases as wheel tilt increases. The computer deals with level wheels, heavily tilted wheels, and semi-tilted wheels. Approximately 95% of wheels are semi-tilted

Accuracy chart

Competing chart

The green area indicates 95% of modern wheels, where accuracy is minimal. This is because the computer incorrectly assumes the wheel is either:

1. Physically perfect (which it never is), or

2. Heavily flawed (which it very rarely is).

In reality, most modern wheels have slight imperfections, but these subtle flaws make an enormous difference to where the ball will actually fall.

In reality, most modern wheels have slight imperfections, but these subtle flaws make an enormous difference to where the ball will actually fall.

Wireless Capable

Without wireless capabilities, only single user application is possible. This means you need to take timings of the wheel, then quickly place bets all by yourself. This means you can't stand at the betting table where you need to be. Furthermore, you will be looking at the wheel then making sudden late bets, which very easily reveals to casinos that you are a roulette computer user. Professional computer teams MUST use more than one player to ensure covert application.

YES (only for 2 player version).

The wireless is encrypted and uses frequency hopping technology so transmissions appear as random static. It is almost impossible to detect.

Range of 30m with perfect sound quality

YES

The wireless is encrypted and uses frequency hopping technology so transmissions appear as random static. It is almost impossible to detect.

Remote version: Unlimited range (uses mobile internet connection)

YES

The wireless is encrypted and uses frequency hopping technology so transmissions appear as random static. It is almost impossible to detect.

Remote version: Unlimited range (uses mobile internet connection)

YES (only for 2 player version)

The wireless is encrypted but does not use frequency hopping. It is still very difficult to detect.

Range of 30m with perfect sound quality

Ability to beat Automated Wheels

Automated wheels typically have in-build "countermeasures" that are supposed to make roulette computers ineffective. However, in most cases, the countermeasures are actually ineffective.

YES, plus it includes features to assess whether or not the automated wheel has countermeasures, and to what degree.

YES, but only about 10% of them.

Quick Resuming of play on each day

For a typical roulette computer, to set up for each new wheel and begin obtaining accurate predictions, you need to have calibrated over approximately 15-30 spins. In a real casino environment, this may take up to an hour before you even make a single profitable bet. "Quick Resuming" enables the player to resume "profitable play" without needing to repeat the setup process each and every day. Typical computers require setup on each new day because the ball deceleration rate of the ball will vary on different days. This is because of air pressure variations on different days.

YES, once you have set up for a wheel and calibrated over about 30 spins, you do NOT need to repeat the process on each new day of play. To setup completely for each new day, you need only 1-5 spins.

NO, you must completely re-do everything from the start each time you play.

Ability to determine where ball will actually fall from the ball track, even when the ball gradually changes the distance it travels (air pressure variations)

The ball's deceleration rate is constantly changing, so the computer must adjust or the predictions will gradually become less accurate. This is a critical feature and without it, you will often achieve no accuracy.

YES, tuning is done automatically while you play. Accuracy is confirmed by audible beeps at the precise moment when the ball is predicted to fall.

The variation of the ball's deceleration rate is automatically learned.

YES, tuning is done automatically while you play. Accuracy is confirmed by audible beeps at the precise moment when the ball is predicted to fall.

The variation of the ball's deceleration rate is automatically learned.

YES, tuning is done automatically while you play. Accuracy is confirmed by audible beeps at the precise moment when the ball is predicted to fall.

The variation of the ball's deceleration rate is automatically learned.

Ability to make predictions when the ball is at the same speed

On wheels with particularly deformed ball tracks, accuracy is greatest when the ball reaches a specific speed. By isolating the ball speed, accuracy can be improved.

YES. The feature can be toggled ON/OFF. When it is ON, accuracy can be maximized. When it is OFF, predictions can be obtained at any point in the spin to ensure you receive a prediction at the latest point in the spin possible.

Ability to generate predictions
"anytime" in the spin

If a computer simply continues to calculate timings after each click you make, and only gives a prediction when the ball reaches a particular speed, very often it will be incapable of giving any prediction on spins. This means you can spend hours in the casino with very few predictions.

YES, for level, tilted and semi-tilted wheels. The user can instantly switch to different modes (isolating ball speed, or "anytime" predictions) without significant loss in accuracy.

How the player is told where to bet

Wireless earpiece (covert audio): single number, OR any amount of numbers you want (so for example the computer can announce 1,2,3,4,5,6,7 or more numbers very quickly). This is important as you don't need to memorize the wheel layout, and begin profiting in less time.

Speakerphone (audio): excellent for practicing, OR

Vibration mode (covert): Vibrations can be used many different ways defined by the user. With the vibration feature, you can set the computer to vibrate when the prediction is above the winning number (as Forester's FFV is used), although this is no different to his FFZ, and very impractical). So if you use the vibration feature, it can be used in a variety of much more practical ways. The user can select the desired option and switch between them instantly

Speakerphone (audio): excellent for practicing, OR

Speakerphone (audio): excellent for practicing

Vibrations only

Variable Vibration Intensity and Duration

YES, you can make vibrational pulses have any duration or intensity you like

N/A (no vibration)

Prediction Process

What is required to make one prediction

Single player version: Two wheel rotor clicks (either full, half revolution, or two revolutions), and either 2,3,4,5 or 6 ball clicks. The order of which is clocked (timed) first can be set by the user (either ball or wheel rotor first).

Two player version: Two wheel rotor clicks (either full, half revolution, or two revolutions), and either 2,3,4,5 or 6 ball clicks. The order of which is clocked (timed) first can be set by the user (either ball or wheel rotor first) OR both players can take timings of the wheel at the same time. This feature enables players to achieve accurate predictions in as little as 1 second after ball release. No other computer has this capability.

You have a very broad range of options to suit any conditions. It is very important to have flexible options, otherwise you will often not get predictions in time.

When the spin begins, one or more players begin clicking a hidden button as the ball and green zero complete revolutions, ntil a prediction is received.

The wheel and ball can be timed independently and simultaneously, but between 1 and 4 players. The more players that take timings, the earlier and more accurate predictions are. Rarely is more than 1 "clocker" is needed (the player taking timings), but the recommended amount of clockers is 2.

Stand near the wheel with the hidden camera. A remote user can adjust aim. When the ball is released, the computer automatically predicts the winning number and sends any amount of bettors the numbers to bet on.

There is very little players at the table need to do. They mostly just focus on betting.

Two wheel rotor clicks (full revolution) and 3-4 clicks for the ball. You then receive the prediction via wireless earpiece.

Take timings for the ball only until the vibration occurs. Note the number under the reference point then place your bets.

Application requires more of an element of skill than our other versions do.

Ability to operate even when you can only see part of the wheel

Rarely do you have a perfectly clear view of the wheel. Computer use must be practical in such situations.

YES, you only need to see the ball and zero pass.

YES. User doesn't even need to look at the wheel.

YES, you only need to see the ball and zero pass.

YES, but for proper application you will need to accurately memorize the wheel layout.

Number of players that can receive predictions with wireless versions

The purpose of using wireless technology (legally) is so not one specific player is looking at the wheel while winning big (to avoid suspicion). If only ONE operator can receive predictions, there is little point to using wireless technology. Multiple player ability is "must have" for serious players.

2 for the two-player version, although additional accessories can be purchased which enable more players.

Unlimited

2 for the 2-player version

1 for the 1-player version

N/A (no wireless)

Number of signal bursts required for prediction

The less sophisticated the wireless technology, the more signal bursts are required, and the easier the signals are to detect

Single player version: 1 burst. The only wireless signal ever sent is an extremely short burst of data that tells the 2nd player where to bet. There are no emissions at all during the timing process.

Two player version: 1-2 bursts

1 burst

Single player version: no wireless

Two player version: 1-2 bursts

N/A (no wireless)

Wireless Encrypted

YES, plus frequency hopping is used to ensure emissions are virtually undetectable. Additionally, the wireless is completely invisible to network scans.

YES (wireless applies only to two-player version)

N/A (no wireless)

Variable Sound Volume and Induction Loop signal strength

Induction loop signals are easily detected if the signal intensity cannot be adjusted.

YES. Adjust to your comfort levels, and to minimize radio emissions from the induction loop. The loop can be detected but only at very close range, and you'd know if someone got that close to you. If you prefer to use no induction loop, this device can rely predictions entirely from phone vibrations.

YES. Adjust to your comfort levels, and to minimize radio emissions from the induction loop.

N/A (no audio)

Wireless Earpiece & Induction loop

YES. Can produce predictions with a wireles earpiece (with induction loop), or via phone vibrations (without induction loop).

YES

YES (each phone sends audio to only one player. so the 1-player version sends audio to 1 player only, and 2-player version gives predictions to 2-players)

YES

Tuning (very important):

Without tuning, predictions are called "raw predictions". Tuning is essential for accuracy.

Visual, Manual, Advanced Automatic Tuning, and Dynamic Algorithms.

Manual with in-built charts: the computer builds a scatter chart for you that you can observe anytime. You observe the charts and rotate predictions to tune manually. The tuned predictions are rotated a set number of pockets. If the wheel is outside a speed range you set, the computer notifies you.

Advanced Automatic Tuning: using proper statistical analysis, the computer will automatically tune the computer for you as you play. If the wheel is outside a speed range you set, the computer notifies you.

Dynamic Tuning: The greater the wheel speed, the further the ball will come to rest from the point of "raw prediction". The "dynamic" feature will automatically tune for each spin based on the speed of the wheel when the ball is predicted to fall. For example, if the wheel timing is 4000MS, then the ball may come to rest +5 pockets from the "raw prediction". If the wheel speed is 3000MS (faster), the ball may come to rest at +15 pockets from the raw prediction. This is a 10 pocket difference. Without this feature, ordinary computers would give predictions as if the wheel speed were the same every time, which it's not. Without this feature, even if a computer perfectly predicted where the ball will actually strike the wheel rotor, the difference in wheel speed between spins may make other computers almost completely ineffective.

Visual, Manual, Advanced Automatic Tuning, and Dynamic Algorithms.

Manual: You manually create charts and rotate predictions to tune manually. The tuned predictions are rotated a set number of pockets.

Risk Assessment

Lets you know when a prediction is likely to be inaccurate due to various factors

YES

It tells you if timings are likely to be inaccurate. It also accurately assesses whether or not the resulting prediction is less likely to be accuracy (adjustable tolerance settings)

YES

It tells you if timings are likely to be inaccurate. It also accurately assesses whether or not the resulting prediction is less likely to be accuracy (adjustable tolerance settings)

YES

It tells you if timings are likely to be inaccurate. It also accurately assesses whether or not the resulting prediction is less likely to be accuracy (adjustable tolerance settings)

Adjusted predictions based on wheel rotor speed

Most computers tune the computer based on the assumption the wheel is the same speed on every spin, which is not the case.

YES, you can set tuning settings so the computer adjust the prediction for specific wheel rotor speeds. This ensures accuracy is optimized over any wheel rotor speed. This can be done with automatic or manual settings.

YES, you can set tuning settings so the computer adjust the prediction for specific wheel rotor speeds. This ensures accuracy is optimized over any wheel rotor speed.

In-Built Scatter Analysis

Where the ball falls and actually strikes the rotor (part with pockets) is NOT necessarily going to be where the ball actually comes to rest. So the computer needs to make adjustments and determine where it will bounce to.

YES, scatter chart and in-built automated statistical analysis of the scatter chart. You do not need to leave the roulette wheel to manually analyze the chart and specify the tuning settings - it is all done automatically.

You can also see all data on charts with detailed analysis to determine your edge.

Ability to make accurate predictions with 8-10 revolutions before the ball falls on level wheels

YES, such early predictions are possible for all wheels providing the ball track is not too deformed (creating far too erratic ball behavior).

NO, unless the wheel is very heavily tilted.

Can take timings of partial revolutions

Without this feature, predictions are given significantly later on slow wheels (rotor).

1 player version: YES, but with significantly decreased accuracy unless the wheel is slow.

2 player version: YES, and both players can take timings of the same spin, which virtually elminates errors even when timing partial revolutions.

YES, and it can use up to 4 different "clockers" (players who take timings) to almost elminate timing errors.

YES. It only needs to see about 1 second of rotor motion, and the green zero can be in any visible location.

Ability to test accuracy of samples before play

This helps you confirm the sample data you obtained is accurate.

YES, You can monitor the ball fall time accuracy. But this is only suitable for heavily tilted wheels. On most wheels, you will not have any knowledge or warning of more subtle errors that have a large impact on prediction accuracy. These issues are resolved as the computer learns the ball deceleration, and updates all data retrospectively. So if the computer learns it was previously incorrect, it automatically updates all previous data and learns from its mistakes.

YES (audible beeps heard and/or vibration felt when ball is predicted to fall). This allows you to instantly test samples for accuracy rather than play 30+ spins only to find out your samples are inaccurate.

It saves precise data on how accurate ball deceleration calculations were. It can either automatically adjust, or be manually adjusted. This ensures the ball deceleration rate is correctly modeled.

NO, if your samples are inaccurate, you wont know until you play 30+ spins

YES

Independently tested

YES, it was sent to a well-known and trusted member of vlsroulette.com who validated our claims. The tester stated the following:

"I can assure you that what I tested was legit, and keep in mind that I was testing on one particular diamond for testing purposes, I could have tested any other diamond but we tested only one,and the test was not to test predicted numbers but only a diamond, and the test was accurate.

And to cap it all, Steve put me in contact with one of his players here in my country and we met up and discussed the computer and he was getting very good results. I can not let out what we discussed, but I can tell you that you would have to be very serious about playing this way and if applied correctly with timing in placing your bets you would do very well, thats all I can tell you"

But keep in mind you don't need to take anyone's word about anything. We provide free trials and public demonstrations where you can do any reasonable testing you want, and on any wheel.

Why Some Computers Are Ineffective

Generally you get what you pay for. There are some major differences between computers that affect overall accuracy and practicality. Below are some of the problems roulette computers must overcome:

Problem 1: HOW the ball will fall

Especially on modern wheels, the ball does not hit a vertical diamond, then be deflected predictably down on nearly every spin. This may have been the case with wheels 10 years ago, but it isn't anymore. On modern wheels, even if a computer correctly predicts where the ball will lose momentum and fall, predictions will not be accurate. Why not? Because the ball may hit a horizontal diamond and be deflected to the other side of the wheel. The ball may clip a horizontal diamond, then hit a vertical diamond. The ball may hit a vertical diamond solidly. It may even completely miss all diamonds. Whatever the case may be, the different types of ball falls often have completely different outcomes.

Putting this into perspective, for a computer to beat modern wheels, it must know not only where the ball will fall, but also HOW it will fall. Our computers are only ones available that determine not only which diamond will be hit, but which part of the diamond will be hit, and the resulting manner in which the ball falls.

Problem 2: WHERE the ball will fall

Ball tracks have many imperfections that appear subtle, but they actually have an enormous influence on where the ball will actually fall from the ball track. Every roulette computer except ours assumes the ball will either:

a. Fall from the ball track at one particular point most times (called a "tilted" wheel and they are quite rare), OR

b. That the wheel is absolutely perfect and that the ball will simply fall from the ball track merely when it reaches a certain speed.

There are numerous factors that determine where the ball is going to fall, and when. See below the three types of wheels you will encounter:

LEFT: The black dots represent where the ball loses momentum and falls from the ball track for each type of wheel (this is just where the ball loses momentum and falls, NOT where it actually strikes the rotor). Heavily tilted wheels are very difficult to find, and level wheels are even rarer. Almost every wheel is semi-tilted, and on such wheels, every computer except ours has a dramatically reduced edge. Specifically that is because 94% of wheels are too tilted to be considered level, but too level to be considered tilted. In most cases, the resulting accuracy for simplistic computers is no better than random.

Problem 3: Air pressure and ball deceleration rate variations

In any environment, air pressure gradually varies over time. When air pressure varies, the deceleration rate of the ball, AND the speed at which the fall falls from the ball track also varies. This means the overall distance the ball will roll will also vary. A player can no more change air pressure than they can change the weather. Significant air pressure variations often occur within approximately 30 minutes, but the change occurs gradually.

Consider the following example: if the ball was released at a particular speed, the ball may complete 18 revolutions before falling. Now if the ball is released at the exact same speed just one hour later, even a very slight air pressure variation may mean the ball will complete 21.3 revolutions before falling - that's a difference of 3.3 whole revolutions, and about 4 extra seconds before the ball falls.

Here's how this will affect affect accuracy if the computer does NOT account for the air pressure variations:

i. If the wheel is tilted: the computer will have an error of about 4 seconds. But the degree of error will not remain consistent, so accuracy rates will gradually decline. When the computer attempts to determine what pocket will be under the dominant ball drop zone when the ball falls, the computer can be way off target. On most tilted wheels, you will still have an edge, but the edge may be half of what is possible.

ii. If the wheel is level: results would be disastrous - the computer will be up to 3.3 whole revolutions off-target. If the degree of error was consistent, there wouldn't be a problem. But in reality the degree of error will change: from 0.1, to 0.2, to 0.3, etc. In such a case, achieving any kind of accuracy would be virtually impossible. This is not even taking into account the various other points raised on this page, in particularly than a discrepancy of even 1cm may make it impossible for the computer to know which diamond will be hit, and which part of the diamond will be hit.

iii. If the wheel is semi-tilted: basically much the same as the level wheel, the degree of error would vary. The results would likely be no better than random.

For a computer to make adjustments for air pressure variation, it must use polynomials. Polynomials are mathematical equations used to generate a "best fit" curve to model the deceleration of the ball.

LEFT: The blue dots represent the actual ball timings. the red line is the "best fit" polynomial curve. The polynomial curve can be seen on our computers in the settings. You can see that despite the obvious timing errors (blue dots) the polynomial curve is smooth and accurate.

As air pressure naturally varies in the casino environment, the ball's deceleration rate will naturally change too. Even a very slight change in ball deceleration rate may make the ball travel several additional revolutions. See the chart below for explanation:

Air pressure variations affect distance ball travels LEFT: In both of these charts, the ball is released at exactly the same speed. The difference in air pressure and therefore the ball deceleration rate is only marginal between each chart. However, even very small deceleration rates make a large difference to the overall distance traveled by the ball.

The yellow area shows the additional difference traveled. Within only 30 spins in the casino (about an hour), this difference in distance is often over 3 revolutions.

Problem 4: Varying ball bounce and scatter with different wheel speeds

When the wheel spins at different speeds, the ball of course behaves differently. In fact, even an imperceivable difference in wheel speed may mean the ball bounces to the opposite side of the predicted area on the wheel.

For now let'sassume a computer perfectly predicts where the ball falls, and how it falls. So let's assume the computer knows exactly which pocket the ball will first hit when it falls. Of course the ball will bounce off the initial pocket before coming to rest elsewhere, but for now we're just talking about where the ball first hits on the rotor (called the "rotor strike point").

With the exception of our computer, every computer assumes the ball will bounce the same distance from the rotor strike point irrespective of the wheel rotor speed. So let's say we charted the distance between the rotor strike point to where the ball actually landed, we would expect the chart to look like below:

LEFT: This is called a ball scatter chart. On the horizontal axis, the value of "0" is where the ball actually hits the wheel rotor (the part with the pockets). You can see the ball bounces and comes to rest approximately 10 pockets from the rotor strike point. Most roulette computers conduct analysis based on the assumption that the wheel rotor speed is exactly the same every time. This incorrect assumption alone often makes some roulette computers completely ineffective.

So while a typical scatter chart initially sounds good in theory, the reality is when the wheel is at different speeds, the ball may behave completely differently. Especially on modern wheels, even the slightest difference in wheel speed can mean the ball bounces an extra 12 or more pockets - modern are designed this way. In such cases, if the computer assumes the wheel is spinning at the same speed every time, accuracy may be no better than random. Our most advanced computers automatically adjust predictions based on the wheel speed of individual spins.

You get what you pay for:

Our roulette computers are the only ones that correctly address all of the above problems. We do not develop our technology as a hobby, or with the primary purpose of selling it - we develop our technology primarily to use it ourselves, and it is a multi-million dollar business for us. We have invested considerable resources to ensure our technology is literally as good as it can be.
