The roulette wheel is a magnificent work of art. Each wheel is individually crafted. And each wheel is an absolutely perfect tool, a tool that, if not perfectly tuned, will work poorly and increase/decrease the actual chances of winning for both the player and the casino.
On a roulette wheel, any physical imperfections can lead to a bias towards a single number, or even a group of numbers. Since roulette wheels are made for long-term use, they can be biased for decades.
Very few technicians are capable of cleaning and refurbishing roulette wheels. And casinos tend to neglect regular maintenance. In brick-and-mortar casinos, you can find roulette wheels with two different problems.
A roulette wheel consists of two basic parts – a heavy wooden bowl with a track for the balls, and a heavy metal spindle that rotates within the bowl. The spindle sits on a solid base and moves effortlessly thanks to bearings. The spindle uses a height adjuster and an upper turret to keep the wheel stationary.
Unbalanced wheels
If the wheel is unbalanced, the head itself dips slightly along the numbered section. The numbers on the roulette wheel are framed by a pocket that holds the ball. As the ball slows down, it jumps over the numbers and into the pocket. If the wheel is tilted to one side, the ball will have a harder time getting over the rim of the wheel. The result? The ball will land more often in the lower part.
Even a slight flaw can skew the roulette wheel. In this case, let's assume that the skew concerns a stretch of five numbers - 31, 18, 6, 21 and 33. A player who bets on these numbers will win more often than he would when playing normal, unbiased roulette.
To exploit this flaw, a player would have to watch hundreds and hundreds of spins and look for a visible bias. Some biases are hard to spot with just the naked eye, but experience will come in handy. Again, to win money, a player must only bet on the spot where the bias is visible, within 4 to a maximum of 6 numbers around it.
Loose frets
A similar situation occurs when the rails or wooden slats inside the roulette wheel become loose. With each spin, the ball lands on the rail, which bounces it back onto the wheel, sometimes several times in a row, until it lands on a number. However, if the rail is loose, the ball does not bounce as much as it should. Instead, it bounces around the bowl, often landing on one or more numbers. In general, the ball is more likely to land on numbers around the rail that is loose.
It is ideal for a player to find a roulette wheel that allows at least two to three frets. In such a case, the ball will often land on a specific spot, regardless of the dealer's roll. The player's goal is to discover such an anomaly and then repeatedly bet on a given roulette wheel to win 4 to 6 numbers.
A roulette wheel with loose frets around the numbers 31 and 18, as well as 18 and 6, gives an increased chance of landing the numbers 18, 6, 21, 33, and 16.
Since the roulette wheel spins in the opposite direction to the ball, the frets simply loosen over time. Some casinos ignore these potential changes and, again due to a lack of service, leave skewed roulette wheels available.
If you have the patience to detect any of these flaws, you will have the opportunity to deprive the casino of very large sums of money. And some roulette systems will also help you in this .
