What is a Biased Roulette Wheel?

There are all kinds of stories and movies about people beating the casinos using high-tech gadgets and phenomenal mind power. Among the “theories” demonstrated in these fictional tales are those using “biased wheels” to win at roulette. Many wonder if this is a valid way to beat the system, and the answer is a bit complicated.

Anyone with roughly one hundred hours of spare time will be able to eventually find out if they can win a ton of money from biased wheels. Why do they require one hundred hours? That is the amount of time most experts believe it will require to record the data and results about the four thousand spins it takes to determine if a wheel is biased.

“If” a wheel is biased? That’s right, your one hundred hours may show you that the wheel you have been watching and documenting is right on tracked and not worn out or biased in the very least. Not sure what a biased wheel is? Basically a biased wheel is one that turns up a number against the established odds. For instance, a player wanting to know if a wheel was biased could watch the game and record the outcome of one thousand consecutive spins, and then review their data to identify every number that appeared more often than every one in thirty-seven spins.

Why thirty-seven? The standard American wheel has thirty-seven spaces. Mathematically that means that each number should appear, on average, one time for every thirty-seven spins. So, the player who watches for James Bond’s favorite number – red seventeen – and sees it come up one out of every twenty spins may have found themselves a biased wheel.

It is only “may have found themselves a biased wheel” because they only recorded one thousand spins, and mathematical theory usually demands far more information and statistics than such a slim sample. This is the reason that experts say that it takes about four thousand spins to tag a biased wheel.

Okay, so has anyone ever successfully identified and used a biased wheel for profit? Yes they most certainly have. Because roulette wheels get so much use and subsequent wear and tear it is quite likely for them to develop a bias. If you add to that the high cost of a new roulette wheel, it becomes even more likely that they can be found. Additionally, some casino owners have asserted that the habits and patterns of their own croupiers, or dealers, can cause a wheel to become biased as well.

The best examples of successful use of biased wheels have always involved teams who monitor and track wheels and then make a few targeted and hugely profitable attacks. The earliest known instance of biased wheel identification took place in the early 1800s. A man named Joseph Jaggers took his own team to Monte Carlo where they clocked every wheel in the city. They then made targeted visits to the wheels and amassed an enormous sum, over three hundred thousand dollars, before heading home.

More recently a single man named Gonzalo Garcia-Pelayo clocked in hundreds of hours monitoring all of the wheels at a casino in Madrid. He used his home computer to analyze the data on each wheel, which then showed him which were biased. He then enlisted his family to visit each of the wheels and over the course of a few years they took in over one million Euros in winnings. While the family was eventually found out, they were not cheating or breaking any laws so all charges were dropped and they kept their winnings!
