Due to the absence of gaming control board inspections in some US gaming establishments, it is possible that all Roulette wheels found in illegal gambling halls could be rigged. It is important to be suspicious about wheels found in any state, except Nevada and New Jersey.
There have been many ways to gaff the roulette wheels since the inception of the game, and some of these are still in use today.
Let’s now discuss the most common methods of rigging a roulette wheel. This is a part of casino practice, particularly at disreputable gambling establishments.
A method to rig a roulette wheel is to determine where the ball will rest on the wheelhead. This is a preferred method. Untrue casinos employ a technique called ball trip. It involves the premature dislodging of the roulette ball from the track so that it settles in a desired area of the wheelhead. This is a common practice for both roulette players and casinos.
The majority of reputable casinos have installed plastic security shields around the roulette wheels. This prevents any gamblers from using ball tripping techniques. Ball tripping is still possible at illegal casinos or establishments located outside Nevada and New Jersey.
Mechanically rigging the wheel
There are many ways to rig a roulette wheel, but the most common is the use of a trippin placed inside the ball track.
If a dealer wants to move the ball off the track, he/she could do so using a level below the edge of the roulette table. This lever can be attached to a cable that is then connected to a spring-loaded pen. The pin can then be projected very thinly onto the track. The pin can be used to force the ball onto the wheelhead by tripping it as the ball spins about the track.
The dealer will often try to get the ball to settle in the single zero or double zero pocket. The dealer will make an exception if there have been large bets placed on these numbers or if someone has bet on either the center or left column.
If the dealer is skilled in visual tracking, he/she may attempt to direct the ball towards a section of the wheelhead where there has been less betting activity. This skill has been demonstrated by some dealers to be quite skilled. It may even lead players to believe that these dealers can aim the ball once it is released. Without the trip pin, a dealer will not be able to direct the ball exactly where he/she wants.
A brake can be fitted to some wheels, which can slow down the wheelhead’s rotation. This “additional element” allows a skilled dealer to sync the speed of the wheelhead and that of the ball so that the wheelhead is correctly positioned whenever it comes in contact with the trippin.
Although it may be obvious, if the trip pin is not well-made, it can be difficult to spot. The trip pin is not visible by players at the table because it is on the side of . The pin is thinner than a 6-inch sewing needle, and the hole in the ball track wall is often very small. It is also partially hidden under the rim of the ball track, making it difficult to see its “modification”.
Some casinos offer a more complex scheme.
The small blocking pins will be used to rig the wheels. Each one is placed at the pocket’s front wall. Two hidden levers will also be found under the roulette table at dealer’s side. The one in red will control the pins, and the other in black, respectively. The levers can be moved by dealers to extend the pins and stop the ball from sinking into the particular set of pockets (red or black). Players will have difficulty identifying them as the pins only protrude during wheelhead rotation.
This scheme is more complicated than a single trippin and is therefore susceptible to failure (jamming). Dealers often use this method of wheel rigging against players who have a tendency to place bets on color.
Another wheel gaffing scheme is the “set wheel”. Casinos can set such wheels to favor certain pockets by increasing or decreasing the distance between the pocket separators. One set of pockets can be made wider while another set will be narrower. These wheels have alternate pockets separators attached to the hub. The dealer can control the width of the alternate pockets by turning the hub in either direction. This is similar to blocking pins.
