    The Top Guide to the Roulette Wheel

    The Player Guide to the Roulette Wheel & Table Layout


    Introducing the Roulette Wheel


    Roulette is a fascinating game of chance. It features a spinning wheel, a ball, inside and outside bets, and a croupier. Online Casino Karamba delves into the inner mechanics of this game with an interesting discussion of roulette wheel mechanics, the roulette table layout, and the rules of roulette. This guide serves as a value-added service for fans of the game!





    Karamba players are privy to many fascinating insights into the roulette wheel. There are multiple roulette game types available to players, notably classic Roulette, European Roulette, French Roulette, and American Roulette. Each roulette variant is crafted according to the specifications of the game in question. Wheels are designed in such a way that randomness is assured on every spin.

    Every roulette wheel is comprised of similar components, including a wheelbase, pockets where the roulette ball can land, a rotor, a ball track where the croupier spins the ball, and diamonds on the wheel. Each of these components serves a specific purpose. Players with an understanding of roulette mechanics will inherently appreciate the game more.

    We will explore each element of the roulette wheel in a structured fashion. The objective is to provide a basic understanding of roulette mechanics so that players can appreciate how elegant and seamless this game really is.

    The Roulette Base

    The outer element of the roulette wheel is known as the base. It is typically comprised of wood, and features a metal interior component. These robust bases are strong enough to withstand dings and dents, without damaging the interior mechanics of the roulette wheel. The most sensitive part of a roulette wheel is the ball track. A slight scratch, imperfection, or attachment can alter the randomness of outcomes.

    The Roulette Shaft

    The shaft of a roulette wheel is the part that supports the rotor. It is otherwise known as a spindle. Proper care and attention are needed to maintain the roulette shaft in impeccable working order. Bent spindles can result in biased roulette wheels, causing the roulette rotor to spin at an angle. There are several different roulette variants, notably European Roulette, French Roulette, and American Roulette. The European and French Roulette variants feature a similar wheel, since there are numbers 0 – 36. The American Roulette wheel features 0 and 00 as well as numbers 1 – 36.


    Roulette Pockets


    All the slots on a roulette wheel are known as pockets. The ball always comes to rest in one of these pockets. From a designer’s perspective, the roulette pockets are frequently changed to reflect the preferences of the casinos in question. In the old days, roulette pockets were deep. This ensured that the roulette ball didn’t bounce around too much and came to rest quickly. Unfortunately, this design resulted in less randomness and too much predictability at casinos.

    The depth of the roulette pockets is but one element to consider when determining the randomness of outcomes on a roulette wheel. Sometimes, other issues come into play such as the pocket separators. If these become loose, they can also absorb the ‘energy’ of the roulette ball and cause it to come to rest much more quickly. The ‘predictability’ of roulette spins can be offset to a degree by changing the design of the pockets.

    Over the years, many intuitive designs have been crafted including the Huxley Starburst design. Roulette tables with this design feature triangular pockets which cause ball deflection in one way or another. This eliminates the predictable element related to roulette gaming by generating a scatter movement of the ball. Some roulette aficionados believe that the triangular pockets may enhance predictability.

    Other design elements include scalloped pockets which are similar to low fret pockets. Nowadays, many casino operators utilise the low fret design in their roulette games. The randomness of a roulette spin is dependent on a host of factors. These include the deepness of pockets, the type of pocket separators there are used, and the dominant diamonds on the roulette wheel. We will address the diamonds in the next section.

    What Are Roulette Diamonds?

    Every roulette wheel has diamonds that protrude on the face of the wheel. These diamonds are designed to change the trajectory of the ball by placing an obstacle in the ball’s path. The dominant diamonds are the ones that have the most wear and tear on them. Nowadays, casinos routinely switch out their roulette wheels if they notice any imperfections on them since this can create biased outcomes.

    Dominant diamonds have typically been associated with predictability, yet this problem has largely been eliminated from bricks and mortar casinos. At online casinos like Karamba, players needn’t concern themselves with roulette diamonds since the outcomes are governed by random number generators (RNGs) and not physical imperfections on the wheel. Various other names have been given to roulette diamonds, notably deflectors, pins, stops, or slats.


    The Roulette Rotor

    The rotor is an important component of the roulette wheel. It includes the inner mechanism that moves along with the pockets in a roulette wheel. The weight of the roulette rotor is approximately 66 lbs. These components can be switched out for other roulette wheels that are similarly constructed. With the right parts, a precision-made roulette rotor can all but eliminate wheel bias in the game. Of all the parts of a roulette wheel, it is the roulette rotor that garners the most attention by the casino since it is a moving part that is subject to wear and tear, imbalances, and imperfections over time.


    The Roulette Ball Track

    The ball track refers to the path the ball travels on the roulette wheel. Land-based casinos use roulette wheels with wooden ball tracks. Most of the time, the roulette ball track is coated with an epoxy resin to strengthen it and make it impervious to scratches and imperfections. Ultimately though, the roulette ball track is subject to wear and tear.

    Well maintained roulette wheels are routinely switched out by casinos to avoid any predictability as a result of imperfections. One of the most durable surfaces for roulette ball tracks is the Velstone ball track. It is durable and capable of withstanding significant wear and tear as a result of the roulette ball, and the roulette dealer’s actions.

    Introducing the Roulette Table Layout

    Roulette players with an affinity for a specific game quickly become accustomed to the table layout. The American Roulette wheel differs from the European Roulette wheel which differs from the French Roulette wheel. It is important to understand the differences between roulette variants and their table layouts. Red and black colour configurations are an intentional inclusion on the roulette wheel. With American Roulette wheels, there are 38 pockets. These include the green 0 and the green 00, as well as numbers 1 through 36. The numbers on the wheel are designated as follows: 0-28-9-26-30-11-7-20-32-17-5-22-34-15-3-24-36-13-1-00-27-10-25-29-12-8-19-31-18-6-21-33-16-4-23-35-14-2.

    The European Roulette layout differs considerably from the American Roulette layout. For starters, there are just 37 pockets on a European Roulette wheel. This includes the green 0 and numbers 1 through 36. This means that there are 37 pockets on the European Roulette wheel as opposed to 38 pockets on the American Roulette wheel. The payout percentages on European Roulette are the same as they are for American Roulette, with the only difference being that there is an additional number on the American Roulette wheel. On European Roulette wheels, the numbers are designated 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. Players will notice that the order of the numbers differs from the order of the numbers on the American Roulette wheel.

    The roulette wheel is made up of different sectors. These are written out in French, since the game has a history that dates back several centuries in France. These sectors are reflective of groups of numbers, and combinations of bits. They include the following:

    Jeu 0 – this sector includes the following numbers on a roulette wheel: 12-35-3-26-0-32 and 15.
    Voisins du Zero – this includes the following set of numbers: 22-18-29-7-28-12-35-3-26-0-32-15-19-4-21-2-25.

    Orphelins – this rather limited set of numbers includes 1-20-14-31-9. There are also other Orphelins including 17-34-6.

    Tiers du Cylindre – these numbers include the following selections: 27-13-36-11-30-8-23-10-5-24-16-33.

    Another interesting selection of beds available to players is known as Neighbour Bets. With Neighbour Bets, players can place a wager 5 consecutive numbers.

On American roulette tables, this includes 0, 00 and Numbers 1 – 36. On European roulette wheels and French roulette wheels, this includes 0, and numbers 1 – 36.

Dozens of players are supported by this type of functionality.

    Players may find the sequencing of roulette wheels to be somewhat confusing; this is intentionally designed to be that way. There is no arithmetic value associated with the sequence of numbers. Besides for being somewhat bewildering, the sequence makes it difficult for players to find any correlation between numbers, sectors, or sections of the wheel. There is complete equality in terms of alternation between red and black numbers. All roulette wheels must have this alternating sequence to ensure that outside bets are associated with the right probability of outcomes. Players will notice that high numbers are flanked by low numbers and vice versa. This is done to prevent a concentration of high numbers, or low numbers in any specific sector of the wheel. In much the same fashion, odds and evens are evenly distributed to prevent any agglomeration of odds, or evens which would otherwise give the player an advantage over the house.

    While French roulette is touted as an entirely different game, it bears many similarities to European roulette. In fact, the European roulette wheel and the French roulette wheel are identical.

A good understanding of the table layout will serve players well when selecting their preferred roulette game. Many of the aforementioned elements are available in all versions of roulette, including online and land-based roulette games.
