In over two and a half decades in this business, we have had the opportunity to encounter customers interested in producing roulette wheels that would allow such manipulation. In this regard, some were willing to generously reward such functionality and even invest in comprehensive research and development. We have never complied with such requests, primarily because doing so would jeopardise our own reputation. However, even setting that aside, in the case of the ball ejection concept we use, achieving such functionality would be extremely complex. In the case of automated roulette wheels, where the ball’s movement is controlled via air jets and the ball is in constant view, this request would be somewhat easier to meet. Namely, with such automated roulette wheels, the movement of the ball is continuously controlled, which also results in noticeably unnatural behaviour, something players often notice. Therefore, the ball’s movement in the event of avoiding a specific number would not necessarily be as noticeable. In the case of electronic roulette wheels, where the ball is ejected through a tube and then moves uncontrollably until it lands in the winning number slot, it is a completely different matter. Theoretically, even in that case, it could be possible to influence the control of the winning number by adjusting the speed of the rotor. However, if we consider dispersed bet options like colour, and the well-known unpredictability of the ball bouncing off stoppers and dividers, implementing such a request in a way that would go unnoticed by the player remains practically an inapplicable theory.

It is crucial to understand that gambling games exist for the house to profit. If you are aware of this and have already decided to have some fun at the casino, roulette, especially electronic roulette with the ball ejection through a tube, logically represents the best choice, especially if you are betting on dispersed combinations like colour. The house edge, which stems from the zero, is still mathematically clear, but it is a transparent way for the gambling operator to cover its costs and make a profit. Therefore, if there is a way for us to harmlessly participate in gambling games, it is precisely with the automated roulette with the ball ejection from a tube, while being aware of the true nature of gambling games, regardless of the rigging of results.

Since the appearance of automated roulette, it has been experimented with different ball ejection concepts, including spring-mechanical ones similar to those we see in pinball machines. However, over time, two main systems remained in wider use, both of which use air pressure to eject the ball, namely compressor and fan systems.

Compressor ball ejection system

The movement of the ball is controlled by compressed air that is ejected in a controlled manner from several subtly placed nozzles. The advantage of this system is that the ball always remains in the player’s sight, which to a certain extent enhances the somewhat shorter game cycle. The key difference between this principle and the original game is the continuous management of the ball’s motion. Such a feature in the eyes of the player represents a potential disadvantage because the ball’s movement is clearly unnatural and raises the suspicion of active manipulation of the outcome of the game. Another disadvantage lies in the sophistication of the system, which due to its complexity is more susceptible to breakdowns and, above all, the need for periodic maintenance of the air compressor, and on top of that, potential challenges related to the placement and noise of the compressor.

Fan ejection system

After reading the winning number, the ball is being “swallowed”, i.e. it is taken by gravity to the starting block located inside the device, from where it is then thrown out onto the balltrack through a spirally formed tube with the help of a centrifugal motor – a fan. Once dropped onto the balltrack, the ball continues to move freely on its way to the final winning number. In this case, the ball is normally out of the player’s sight for a few seconds, although by adding a second ball to the system, this can be avoided in such a way that the second ball flies out in sync with the fall down of the first.

Conclusion

With a compressor ejection system, the ball is normally in the player’s sight all the time and is usually ejected in a different direction each time. But on the other hand, the continuously controlled movement of the ball arouses suspicion among the players about the manipulation of the result, and the sophisticated system, which requires periodic maintenance and frequently relocated compressor station, complicates the operators’ job.

Automatic roulette cylinders with a fan ball ejection system may or may not have a bilateral ball ejection function – because of the ball supply pipe they are often slightly larger in diameter, and in the case of using only one ball, it is not in the player’s sight all the time. However, the movement of the ball is free and natural, the system is robust in its conceptual simplicity, and does not require displaced elements and periodic maintenance.
