How to Use Roulette Wheel Bias Today

Roulette Wheel Logo And Table

Roulette isn’t the first game that people come running to when they’re looking to beat the casino. After all, roulette doesn’t have a commonly-known advantage play technique, like blackjack (card counting).

Nevertheless, this game can be beaten through wheel bias. This advantage gambling method has helped some players win millions of dollars.

The catch, though, is that wheel bias isn’t as easy to pull off these days. In fact, some players don’t think that it’s possible at all.

But you actually can still use wheel bias to earn profits today. I’ll explain how after I discuss more on the technique itself.

How Does Wheel Bias Work?

Wheel bias involves looking for roulette wheels that favor certain pockets and sections. For example, you may discover a wheel that sees the ball go into the 16-4-23-35-14 section a disproportionate amount of times.

This bias occurs when wheels suffer wear and tear and aren’t as random as they’re supposed to be. This phenomenon can occur through a number of ways, including unequal pocket sizes, deformed balls, a shaky wheel shaft, or loose frets.

Of course, the casino doesn’t put a blinking sign next to biased wheels. They normally don’t know about such wheels if they’re still on the floor.

Instead, you need to put the work into figuring out if a casino has one or more biased wheels. Some claim that you can even spot wheel imperfections with a trained eye.

But even if you do think you’ve found an imperfection, you must record results for a measurable amount of time. After all, it’s difficult to notice a deformed ball or shaky wheel shaft before the casino does.

The amount of data you need depends on whether you’re looking for bias towards specific pockets or sections. The latter doesn’t require as much data because it’s easier to spot a biased section than single pockets.

Here’s an example on how you can record data for section bias:

  • You track 1,000 spins.
  • You put the data into a spreadsheet.
  • You discover that a section of 10 numbers between 27 and 6 is biased.

You need to analyze the wheel a lot longer to find out if certain pockets are off. Some believe that you need anywhere between 5,000 and 10,000 spins’ worth of data to discover pocket bias.

Of course, the benefit to looking for individual biased numbers is that you can make more money. Single bets pay out at 35 to 1 when you win.

Why Was Wheel Bias More Common Decades Ago?

As mentioned before, some people have become millionaires through wheel bias. However, these stories seem more like ancient legends than feats that can still be accomplished today.

For example, an English engineer named Joseph Jagger made a £65,000 profit (£7 million) while playing roulette in Monte Carlo. He took advantage of a biased wheel at the Beaux-Arts Casino before the employer switched around the wheels to throw him off.

In the 1990s, Gonzalo Garcia-Pelayo made over €1.5 million at a combination of Spanish and Las Vegas casinos. His story was documented in a History Channel documentary called Breaking Vegas: The Roulette Assault.

Jagger and Pelayo aren’t the only players who’ve won big through roulette. But stories of heroic winners are becoming less common today.

What’s changed from the nineties and beforehand? The roulette wheels.

Casinos used to feature wooden wheels that were more exploitable.

In recent years, they’ve rolled out Starburst wheels. Developed by John Huxley, the Starburst model features metal frets and shallower pockets. These two features help eliminate two of the main sources for bias.

British casinos were the first to roll out Starburst wheels. They did so after finding that they were losing a bunch of money to roulette players in the 1980s.

Atlantic City and Vegas casinos have since followed suit. Therefore, you’ll have a tougher time finding a beatable roulette game today than ever before.

Casinos Have Stepped up Their Game These Days

Starburst roulette wheels aren’t the only things that gambling establishments have changed. Nowadays, casinos run regular inspections on roulette wheels to ensure they’re running properly.

Staff members are trained to look at the wheel shaft, frets, pockets, balls, and more. They’re very good at identifying when one or more of these elements are out of whack.

They also electronically monitor results. You’ve probably noticed electronic boards near roulette wheels that display the last 10 or 20 numbers.

These boards serve two purposes:

  • To prevent wheel bias
  • To cater to players who like gambling based on past results

Between the combination of more frequent inspections and better equipment, casinos do a better job of stopping wheel bias than at any other point in history.

Finding Biased Roulette Wheels Today

TCS John Huxley provides revolutionary wheels and equipment that help casinos prevent advantage play. Nevertheless, modern technology hasn’t completely closed out the chance of bias.

This tech mainly concentrates on winning numbers over a long period of time. It doesn’t, however, keep track of various factors that can lead to biased numbers (e.g. ball, casino temperature, shaft).

Sometimes, casinos will still keep biased wheels on the floor even if they know about them.

They’d rather only take action if somebody exploits a wheel instead of adding an expensive replacement.

That said, wheel bias is still possible to some extent. Here’s a recap of certain factors that can lead to a biased wheel:

  • Bent frets — Over time, frets can become bent or suffer other damage.
  • Deformed balls — A ball can suffer nicks or even complete design flaws. Such balls make a rattling sound on the track.
  • Deformed ball track — Sometimes, the entire ball track will be messed up. In these cases, the ball will make a rattling sound at specific points on the wheel.
  • Flawed wheel shaft — The wheel shaft can become uneven over time and slightly shift the wheel toward a certain section.
  • Older wheels — Some casinos still opt for classic roulette wheels that aren’t as costly. These don’t have metal frets and shallow pockets, leaving them more susceptible to bias.


Roulette wheel bias certainly isn’t as easy to pull off as it was decades ago. Casinos have taken big steps to cut off this advantage play technique.

For starters, most gambling venues now employ Starburst wheels. These feature shallower pockets and metal frets in an effort to prevent wear and tear.

Casinos also perform regular inspections on their wheels. Staff members look for various flaws that could lead to wheel bias each day.

Gambling establishments also have electronic boards that track results. These boards feed the casino data, which they can use to figure out if any pockets or sections are biased.

These factors make it harder to earn money from wheel bias than in the past, when players like Joseph Jagger and Gonzalo Garcia-Pelayo made fortunes. Nevertheless, this advantage play technique is still possible to some degree.

The key is to understand some of the factors that can cause wheel bias.

These include damaged frets, deformed balls, older wheels, flawed wheel shafts, and damaged ball tracks.

Assuming you can master spotting these imperfections, or perceived imperfections, then you can move on to recording results. The point of recording spins is to gather enough evidence to confirm the bias.

You’ll need at least 500 to 1,000 spins to find section bias with any degree of success. Anywhere from 5,000 to 10,000 spins can provide you with pocket bias.

Unfortunately, finding such wheels is harder than ever before. But you can still do it by sticking to tried-and-true methods and putting enough work into the matter.
