When you Find a Biased Wheel
Repeat the test if a wheel appears to be skewed. If you don’t do this, there’s still a chance the bias isn’t real—and this is necessary to confirm the bias. There is very little possibility that it is just coincidence if the test is successful.

Keep in mind to maintain as much consistency as you can. If nearly identical charts appear, you’ve almost certainly discovered a biased wheel.

Place your wagers to play the wheel, presuming that the conditions are as similar as possible. Keep a close eye on the wheel as you play to see if anything changes. Consider paying particular attention to elements like tilt, ball drop off spots, ball type changes, etc. The prejudice might disappear if circumstances change, at least until the circumstances return to how they were before.

When people talk about winning at roulette or gaining an advantage, one topic that always comes up is the idea of biased roulette wheels. Realistically speaking, you won’t uncover a bias towards red or black because you would need to clock at least 4000 spins to actually identify a pattern in a wheel.

You’ll at most discover a bias toward a particular group of numbers. Because the house edge in roulette depends on the chances consistently being 37 to 1 for each number, casinos do not want a biased wheel. The casino loses money if some specific numbers are paid out more frequently than they should be. A biased wheel differs from a fixed game of blackjack in this regard, although casinos don’t really care to fix any of their games as the house edge is favorable in every single one of them.

You should wager individual numbers as much as you can if you can discover a biased wheel and you have a sufficient amount of confidence in the bias. You don’t want to waste it on wagers with low payouts if you find yourself in a rare circumstance where you have an advantage over the casino. Dealer signature is something similar to wheel bias but not quite the same. Some roulette dealers have been spinning the wheel for so long that they consistently follow the same pattern and speed. As a result, it is possible that some numbers will appear more frequently than others.

It’s usually preferable to locate an older dealer who appears to be genuinely bored and to have been doing this for a while if you’re seeking for this type of advantage play. You don’t want a young person who is still learning how to spin the wheel. You need someone who has spun it so frequently that it is instinctive and foreseeable.

Biased Roulette Wheel?
Any roulette wheel that produces outcomes that are not consistent with what would be predicted by chance is referred to as a “biased wheel.” There are two possible ways for this to happen: either the casino can manipulate a wheel to produce non-random results, or a wheel may have flaws that cause biased outcomes.

Even though they are less frequent today, rigged wheels were a mainstay of underground casinos for the most of the first half of the 20th century. These wheels were used by the operators to cheat the public and accept more big bets than they should have.

Of course, this method was risky since irate customers who learned about these wheels would undoubtedly feel cheated. Even the majority of uncontrolled casinos eventually came to the conclusion that using such wheels was just not worth the risk because roulette tables are already profitable even without any rigging. Most people refer to accidentally biased roulette wheels that catch casinos off guard when they talk about biased roulette wheels.

Due to the complexity of roulette wheels, even a slight unbalance can subtly change the outcome, making certain areas of the wheel more likely to be the winner than others. Given that the casino’s house edge in roulette isn’t particularly high, even a slight bias occasionally allows players to gain the upper hand provided they know where to make their bets.

Biased Wheel Play Introduction
A wheel that has one or more numbers that are more likely to win is said to be biased. It happens as a result of a manufacturing flaw or normal wheel wear and tear. Although a bias can be seen on even brand-new wheels, it is more common on older ones. Other than color or number, everything that distinguishes one pocket from any other typically results in bias of some kind.

Biased wheels are uncommon, according to the majority of experts, although they do occur. Every wheel is biased to some extent because it is impossible to make a “perfect” wheel, but whether or not that bias is sufficient to offset the house edge depends on the wheel in question. The majority of the time it isn’t, but as was mentioned in earlier chapters, winning at roulette typically requires a variety of different strategies that all add to your “overall” edge.

A biased wheel is still beneficial even if it only gives you a 0.5% advantage. Despite the fact that the house edge is also quite small, the majority of other players can lose thousands of dollars very rapidly. It takes more than simply determining which numbers spin the most to identify and take advantage of biased wheels. There is a great deal more to it, as this chapter will reveal.

You can simplify your life by using the web software that is offered to gamers, which will perform a bias analysis for you. The bias will be included in the custom variations if it is statistically significant. Nevertheless, this part will describe how to identify and take advantage of a wheel bias without the use of any software.

Wheel Identification
Once a clocker has gathered sufficient data for a particular wheel, he or she must assess it to determine whether the wheel exhibits any biases. He or she must first identify the numbers that have happened in the data set the most frequently.

Any given number has a 1/38 chance of winning on a double-zero wheel, or once every 38 turns. The number that frequently wins would be occurring more frequently than usual. What frequency of occurrence a clocker would deem beyond the typical range for a random wheel may be a question. The solution is undoubtedly statistical in nature and related to confidence intervals and significance tests, which we will stay away from.

The following regulation has been proposed by industry experts:
One should pay more attention to a roulette wheel if a certain number wins 10 or more times in 200 spins and its two surrounding numbers also surpass the average of 5.3 wins in 200 spins (valid only for a double-zero wheel). If the number 17 appears 11 times in 200 spins, that occurrence won’t mean much on its own.

However, a clocker will undoubtedly need to look at that wheel if the surrounding digits also appeared at least seven times apiece. The likelihood of this specific winning number occurring is predicted to be 1 in 38, or 2.63% of the time. It is predicted that a number will win 11 times out of 200 spins (11 / 100 = 0.055), or somewhat more than twice the predicted rate. This does not demand attention on its own.

Actually, the wheel would still be regarded as random even if that number appeared twice as frequently. However, if both neighboring numbers also won more frequently than expected, this would support the existence of a normal distribution curve (a bell-shaped curve).

Is it feasible to use wheel bias in roulette to your advantage?
There is a discussion going on as to whether it is still possible to find and take advantage of a biased roulette wheel considering the developments in manufacturing technology and bias monitoring devices included into modern roulette wheels. It is unquestionably true that these technologies exist and that they make it much more difficult to successfully exploit wheel prejudice. However, there is reason to think that it may still be possible under specific circumstances:

• Most casinos, although not all, have bias detection systems in place.
• Because roulette wheels are expensive, casinos frequently utilize them, which raises the possibility that a large bias forms.
• Smaller venues may be more likely to use biased older, second-hand wheels and to do bias monitoring less frequently, if at all. This is because they lack the infrastructure of premier providers.
• Even if a bias is identified, the casino may not necessarily take immediate action unless they observe someone abusing it.

It is not at all simple, and you require the following in order to learn how to regularly win at roulette:
• Diligence – to monitor wheel performance over an adequate period of time to collect the necessary data for a representative statistical study.
• Statistical skills – to evaluate your results and decide whether you can use them to your advantage.
• the ability to take advantage of a prejudice that has been found.
• Discipline – must maintain your course of action until you see results (not gonna happen overnight).
• The majority of biases are small and only profitable in the long run, thus they require an initial investment.

Types of Bias
Pocket Bias: The ball will lean toward specific pockets.
Section Bias: It will favor certain wheel sectors.
Dynamic Bias: This prejudice only lasts for a brief period of time (usually a few hundred spins). It can be difficult to identify such a bias manually, but online custom variant software can do it for you. In most cases, you can foresee how a bias would develop and change your bets accordingly. This form of bias is completely ignored by “modern” wheel analysis software, which is to your advantage.

Examples of Biased Roulette Wheels
Players have taken advantage of rigged roulette wheels in casinos all around the world in a number of high-profile cases. In 1873, Joseph Jagger managed to win roughly £65,000 from the Beaux-Arts Casino in Monte Carlo, which is still arguably the first and most famous instance of a gambler winning big by studying the outcomes of a roulette wheel.

Jagger discovered that one of the roulette wheels in the casino had a blatant bias favoring a cluster of nine numbers by having six clerks to record the outcomes from all six roulette wheels. Jagger was occasionally forced into significant loses when the casino retaliated by shifting the position of the wheels. But ultimately, Jagger took home the prize, which is now worth more than £3 million (when adjusted for inflation).

In the 1990s, Gonzalo Garcia-Pelayo made comparable attempts to monitor the outcomes of the roulette wheels at the Casino de Madrid, which is a more modern example. Garcia-Pelayo eventually discovered a wheel with a bias, and over the course of several days, he was able to win more than one million euros.

When the casino discovered what he was doing, they tried to take legal action, but the courts rejected their case, concluding that Garcia-Pelayo had not broken any laws. They came to the conclusion that the casino was at blame for failing to maintain its roulette wheels.

Why Does Wheel Bias Suck in Modern Roulette?
If you could just document outcomes for about an hour on each wheel and finally uncover flaws, wheel bias would be fantastic. Then, by participating in the biased wheel game, you may win thousands or even millions of dollars.

Unfortunately, it will take much longer than 1-2 hours to complete this process. You are compelled to keep track of the outcomes for days or even weeks while looking for a biased wheel.

“You must record at least 500 spins per wheel if you’re searching for “section bias,” which is when a whole section is skewed. You’ll require 4,000 to 5,000 credible spins of data while looking for “pocket bias.” Because you may profit from single-number bets, you can make more money through biased pockets (35:1 payout). Section bias, however, is considerably simpler to identify, as can be seen.”

However, I don’t use the word “easier” lightly. It will probably take you roughly 10 hours to gather information on 500 wheel spins.

What if a biased wheel is not present? Perhaps even in the entire casino? Or on the subsequent wheel?

Starburst wheels add even another obstacle to your goal. Compared to earlier wooden wheels, this brand’s frets are made of metal, and it is considerably more robust. Nowadays, many casinos utilize Starburst products to guard against being beaten by players with an edge. To benefit from this strategy, you normally need to locate a casino with wooden wheels.

Why Casino Wheel Bias Technology is Inadequate
Most casinos have bias analysis equipment, however others don’t even have that. TCS John Huxley is currently the industry’s top provider of such technology. While some technology merely considers the winning number, others consider variables like wheel speed in conjunction with winning numbers.

Rarely does a casino’s software adjust for the many factors, such as the room’s temperature, the presence of the ball in play, the dealer, different combinations of wheel bases and rotors, etc. A serious player will gain from casinos’ conviction that their wheels aren’t skewed, especially those that just look at winning numbers. However, even if a casino is aware that a wheel has a bias, they frequently won’t take action until they detect someone is abusing it.

Summary
Finding wheel bias the conventional manner is a laborious task. In order to find a broken wheel, you must explore the casino and keep track of thousands of spins.

Michael Small suggests a far simpler method for identifying faulty wheels and making money. Simply keep an eye out to observe if the ball continues to fall from a specific area on the rim. The likelihood is that you won’t make much, if any, money using this technique either. However, Small’s guidance is entertaining to follow and leads you closer to recognizing prejudice.
