Coming across a roulette wheel with a particular bias is nothing extraordinary. Casino staff don’t usually focus on this specific topic for obvious reasons and would also do anything to convince roulette players that a biased wheel is an infrequent occurrence. The reason is not far-fetched, and why they do that is that any bias, when discovered by a player, maybe indeed used to advantage and as a result, this would adversely affect casino gain.
Different wheel biases can be pinpointed. Some of these biases were caused by accident, others were a result of deliberate actions, while the third group of tendencies were introduced after years of heavy use.
The roulette wheel termed random when it is perfectly symmetrical, balanced and dimensional. For example, the width and depth of each roulette ball pocket should be the same, the frets have to be the same height and should also have the same stiffness, the roulette ball track should also be perfectly circular and flat, and the pocket pads need to be resilient equally.
The truth is, such a highest number on a roulette wheel doesn’t exist. Even those roulette wheels’ design may appear to have consistent manufacturing variances. That leads us to what is called “a random enough wheel.”
It doesn’t matter what inherent bias a wheel may have, it is not an easy task detect the bias wheel, while in many other cases, the preference is not very strong to neutralize the advantage of the house. A new roulette wheel shouldn’t just be random, but it also needs to be sufficiently jagged to help preserve the condition after many years of constant use.
A wheel that’s random enough when it is new doesn’t mean it is immune to flaws as it amortizes. The defects may be as a result of ordinary wear, deliberate actions, or accidental damage. Little anomalies during the construction may seem inferior when the wheel is not placed into service – it could lead to particular not-so-random features.
On the flip side, the number of wheels usually develop wear patterns, it could lead to various biases, most especially if those wheels have lacked ideal maintenance. These biases can be detected, and exploited, by vigilant players via methodical observation during gameplay.
As we’ve discussed earlier, the roulette ball tends to spin in the opposite direction to that of the wheel head rotation, because the number of players tends to believe that it is impossible for a roulette wheel to give more values to some numbers. Interestingly, it is not that hard to cause a wheel to favour different groups of numbers. A roulette wheel can also be intentional set to select black or red, odd or even numbers.
Ball Drop-Off Point
A unique feature of the older roulette wheel is that the roulette ball usually leaves the ball track from the same spot on the base of the bowl. It can also be as a result of slight warpage of the other circular path.
