# Roulette Calculators That Predict Winning Numbers

You may have read about players winning vast sums with hidden calculators. “Roulette calculators” is another name for roulette computers.

## The Basics Of Roulette Calculators

Essentially they are hidden electronic devices that measure the variables of the roulette wheel. Most commonly, the variables are the ball speed, the rotor speed, and the deceleration rates of each. At least this is how a typical roulette computer works.

Usually to determine the rotor and ball speed, the player clicks a hidden button. This button is usually hidden under the player’s toe, inside their shoe. You may assume that the ball or wheel is too fast for the players clicks to have any accuracy. Generally most players are able to make timings within 50 ms accuracy. This is usually fine when the rotor is slower. But errors in calculations snowball over time, and especially with faster rotors.

## Timing Errors and Inaccuracies

There are a few ways to deal with timing errors, as discussed below.

Firstly, the player can take timings of multiple revolutions. If only one revolution is timed, the errors can be manageable. Essentially if calculations are based on inaccurate measurements, then inevitably the predictions won’t be accurate.

Secondly, multiple players can be used to take timings of the same revolutions. For example, the players may require a very early prediction. Perhaps they only have time to measure the speed of one ball revolution. A single player measuring such timings with a hidden button cannot be accurate. However, two or more players measuring the speed significantly reduces errors in calculations. As far as we are aware, the only roulette calculators that have this ability are here.

## Ineffective Calculators

To this point, the only roulette calculators discussed are roulette computers. But there are in fact many different types of calculators, although most have little to no effect. These are the typical calculators used for online casino roulette, where there is no physical roulette wheel.

An example of a completely ineffective calculator is one which tracks repeat numbers. For example, it’s a common misconception that hot numbers are more likely to repeat. A hot number is basically a number that has spun more frequently than others, at least in recent times.

A hot number calculator is the simplest example. There are considerably more complex calculators, which are equally ineffective. It is common gambler’s fallacy when the player thinks a pattern exists, which does not exist in reality. A simple way to determine if a theory is fallacy, is to test carefully. But you can’t just test with short-term data. Short-term results are meaningless and subject to variation. Basically in the short term, anything can happen.

The emphasis of testing should be on whether or not the best selection method increases the accuracy of predictions. Put into a practical context, you’d know there are thirty-seven numbers on the European roulette wheel. So statistically, if you bet on one number, you would win an average of one in thirty-seven spins. The payout is just 35-1, which means payouts are unfair. This is the house edge of -2.7%. So even when you win, you still lose because the payouts are unfair.

So how can you overcome the unfair payouts? The only way is by increasing your accuracy of predictions, to be significantly better than random. In this case, random is one in thirty-seven.

## Determining The Accuracy Of Calculators

Testing roulette computers is very tricky business. You need to know exactly what you are looking for. As a general rule, testing any method, including roulette computers or calculators, you need to compare statistical averages to long-term results in trials. It is important to understand the roulette odds for comparison.

If for example you only considered thirty-seven spins, while betting on just one number, you may win three or so times. If you calculate your success rate, it would appear that you had an edge over the casino. If a different player on another table used the same system, they may get zero hits in thirty-seven spins, indicating their system didn’t work at all. If you base success rates only on the bare results such as this, you won’t have a clear understanding of the effectiveness of your system or calculator.

Typically with calculators such as roulette computers, the success is measured in a direct number hit rate. For example, one in fifteen spins. This means the player can expect approximately one win every fifteen spins, if they were betting only one number. Again this data alone is insufficient to measure accuracy. Therefore not only the direct number hit rate is considered, but also how frequently the ball landed close to the predicted number. If this information was placed on a chart, the effectiveness of a roulette computer is easy to see and verify.

In most cases, the chart will display more than one area where the ball is landing. These areas are called peaks. It is not uncommon to have two or three peaks on a chart. Usually the number of peaks corresponds to the number of dominant diamonds. A dominant diamond is simply a metal deflector that the ball hits more frequently than others.

To better understand the effect of dominant diamonds, consider the following. If you have a wheel at home, keep the rotor static and do not spin it. Just spin the ball very softly. After around ten or so spins, you will find the ball tends to hit specific diamonds more than others. Note the number under a particular diamond. For example, number 0 may be at a specific point. Again keep the rotor static and do not spin it. After each spin, measure the distance in pockets between your reference number, and the winning number. Place these distances on a chart with the x-axis values being 0 to 37. You will find almost always the number of dominant diamonds corresponds to the number of peaks on your chart. So if you have two particular diamonds that are always hit by the ball, you will have two clear peaks on your chart. The main difference in real play is the rotor is spinning too, but the physics is all the same.

Testing roulette calculators like roulette computers is far more involved, because there is far more to consider than plain statistics. Firstly you need to determine if the method of timing acquisition is accurate. Already with manual clicks of a hidden button, there is around 50 ms of error. While this can be reduced with methods such as multiple clicks and multiple revolutions, there is still some error. But with a correctly designed calculator, the overall errors from timings are negligible. There are also various other problems that need to be solved by accurate algorithms and calculations. For example, the ball deceleration rate is not linear, and is subject to constant change. Therefore robust methods must be used to test such algorithms. Further details of testing is beyond the scope of this article.
