Biased Roulette Wheel: Analysis, Techniques , and Exploits



Theoretically, roulette should be a guaranteed source of income for casino owners. The house advantage will eventually become apparent, and this game will continue to generate profits for as long as a casino is operational. Even while some players may succeed from time to time, the casino is going to win in the long run.

However, when an establishment has a biased roulette wheel, this theory is rendered useless. Experienced players have frequently discovered and taken advantage of biased roulette wheels throughout the past 200 years, beating the house and making enormous gains over the course of weeks, months, and even years.

The industry is now more secure than ever and there are many regulations in place that govern the market, including roulette games. These regulations make the games ethical, and, to a certain extent, fair. There are many online roulette New Jersey websites and they are regulated by the Division of Gaming Enforcement, which takes care of the players and providers.

That being said, history is filled with instances of casinos providing roulette games that are biased in one way or another. Let’s first take a look at what is considered to be a biased wheel.

How Can a Roulette Wheel be Biased?

Any roulette wheel that produces outcomes that are not purely governed by chance and the results are manipulated in any way is referred to as a “biased wheel.” There are a couple of possible ways for this to happen: either the casino can manipulate a wheel to produce results that are not random, or a roulette game may have flaws that cause biased outcomes.

Even though they are less frequent today, rigged wheels were a cornerstone of underground casinos throughout most of the 20th century’s first half. These wheels were used by the operators to cheat the public and accept bigger bets than they should have. Of course, this method was risky since irate consumers who learned about these roulettes would undoubtedly feel cheated. Most of the uncontrolled casinos finally came to the conclusion that using such wheels was just not worth the risk because roulette tables are already profitable even without any manipulation.

When people talk about roulette wheels that are biased most people refer to accidentally biased roulette wheels that catch casinos off guard. Due to the complexity of roulette wheels, even a slight unbalance can change the outcome, making a ball more likely to land on certain areas of the wheel. 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.

Most Infamous Biased Roulette Wheels

In 1873, Joseph Jagger managed to win roughly £65,000 from the Beaux-Arts Casino in Monte Carlo, which is arguably the earliest and the most famous instance of a person winning large by studying the outcomes of a roulette wheel. Jagger discovered that one of the roulette wheels at the casino had a blatant bias favoring a cluster of nine numbers by having six clerks record the outcomes from all of the roulette wheels. Jagger occasionally lost a lot of money 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.

In the 1990s, G.Garcia-Pelayo made similar attempts to monitor the outcomes of the roulette wheels at the Casino de Madrid. Garcia-Pelayo eventually discovered a wheel with a bias, and over the course of many days, he was able to win more than €1 million. When the establishment discovered what the player 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 establishment was at blame for failing to maintain its roulette wheels.
