The roulette wheel is an archetypal symbol in the gambling world. Doesn’t an image of a roulette wheel pop up in your mind when you think of a casino or a gambling establishment, be it online or offline? To a beginner, the roulette wheel could seem very complicated with so many numbers and colours that mean something. However, to the experienced players, it only signifies a brilliant potential to win big. The secret to enjoying a good roulette game is to first understand the roulette wheel properly, along with the logic of this game and how it is designed.

It is commonly believed that the positioning of all the numbers is random, as it also seems that way when you first look at it, but the truth is very different. The positioning of the numbers varies between different game variations, for example, in European and American roulette, and it is undoubtedly done that way for a reason.

The Sequence in American Roulette Wheel 

American roulette is said to have the highest house edge as compared to all other roulette games at 5.26%. It is because there is an extra numbered slot, which is represented by the ‘double zero’. Because of this addition, the total number of the roulette wheel pockets is 38 instead of 37 as in the standard roulette wheel versions. In the American The sequence, in this case, is laid out as follows:

0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 24, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, and 2.

The Sequence in European Roulette Wheel

 The European Roulette Wheel is the more popular one of the two and has 37 numbered pockets, which includes the numbers 1 – 36 and also a single zero. Due to this single zero, the house edge is much lower as compared to the American one with an average of only 2.7%. Therefore, the European roulette wheel offers new winning potential than its American counterpart. The sequence of the numbers in this one is displayed as follows:

0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10,5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26

The Logic Behind the Layout of the Roulette Wheel

The number sequence on the roulette wheel is designed carefully to achieve various things and is not random at all.

Red and black are always placed alternately – Be it any roulette wheel you decide to play, two adjacent pockets would still be of different colours. There is no roulette wheel, which would have adjacent pockets with the same colour.

Low and high numbers are placed alternately – The European roulette wheel would seldom feature low and high numbers placed next to each other, except 5 and 10. In the American roulette wheel, in contrast, usually high numbers are placed next to low numbers, making the European version the more balanced of the two. 

Distribution of odd and even numbers is even along with the roulette wheel – Normally, there should not be over two odd or even numbers placed next to each other on a European version. The roulette wheel is as complicated as it is exciting and fascinating. You can choose to play online roulette in various online casinos which enable you to enjoy a game in precisely the same manner as in a brick-and-mortar casino.

 Construction and Trustworthiness of a Roulette Wheel

Though there are multiple popular manufacturers of roulette wheels, there are some essential requirements for constructing a professional roulette wheel. They are as follows:

The weight of the wheel should be distributed evenly throughout.

The wheel and ball should be made of non-magnetic substances to avoid any interference from magnetic sources.

The cylinder must rotate and be able to move freely of its own accord. However, all the affixed parts of the roulette wheel should be secure while being free from movement.

The ball pockets or different compartments on the roulette wheel track or the wheel ring should adhere to the following rules:

Each compartment or pocket must have the same dimensions as every other compartment.

The compartments should be evenly spaced out.

They must enable the roulette ball to land and rest smoothly and adequately within the compartment.

If even one of these conditions is not met to the fullest, then you would have an intentionally rigged roulette wheel, which could be controlled by the casino. There are cases, where such a biased or defective wheel could not have caught the attention of the casino owners, which is when some expert players could take advantage of it.
