The roulette wheel is, of course, designed so that it can be played continuously. The production follows standards that have been in place for decades. On the other hand, there are not enough technicians who can cleanse and restore these devices. And when roulette is neglected, two problems can arise.
Roulette is a wooden bowl
The roulette wheel itself consists of a wooden bowl in which the rotating head turns. The head or headstock sits on a fixed shaft, and special bearings ensure smooth rotational movement. The height regulator together with the upper roulette tower ensures stability.
If the wheel is imperfectly balanced, it will start to bias gently to a certain side and favour a specific group of numbers. Each number has a case below it with small wooden bars on both sides, thanks to which the ball stops at a given place after turning the roulette wheel. However, as the unbalanced roulette wheel is lower in one area, the ball will likely stop there more often.
A similar situation occurs when the roulette pockets or bars are loose. When the roulette ball hits a stable place, it bounces off with greater force. When parts of the field are flexible, the ball does not bounce as strongly and remain in one area.
How does such roulette look like?
Biased roulette, a nightmare for casino operators, often has two or three adjacent loose pockets. In such roulettes, the ball remains on the pockets or stops in a specific part. Let’s look at an example. Let’s say the loose numbers are 31 and 18 and at the same time 18 and 6. In all probability, the ball will then fall on numbers 18, 6, 21, 33, and 16. (Assuming the roulette wheel spins counter clockwise.)
When the roulette wheel spins in one direction and the ball in the opposite direction, the pockets are released naturally due to the ball landing in the opposite direction on the field. It is, therefore, understandable that roulettes need regular maintenance to prevent these problems. Once the roulette wheel is neglected, players will be happy to take advantage of these roulettes.
Which has happened several times in history. One of the best-known cases is the story of Joseph Jagger, who, at the end of the 19th century, searched French casinos for these biased roulettes and won considerable money on them.
