Roulette Wheel & Table

Roulette is an iconic casino game that has a rich history, dating back centuries. French mathematician Blaise Pascal is credited with inventing the wheel that we now call ‘the roulette wheel’. He invented the wheel while attempting to create a perpetual-motion machine. Expectedly, he failed to defy physics, but something did come out of his invention: the spinning wheel that we now know roulette. The word comes from the French word ‘rouelle’, which means a wheel. Roulette is a diminutive of it, and the literal translation would be ‘a little wheel’.

He presented the game, and the first roulette wheel, even though simpler in design compared to the modern casino roulette wheel that we know today, had the same purpose: to determine the winning number in a game of chance.

While the original roulette wheel consisted of a wooden disk and slots where the ball would land in, the modern roulette wheel is constructed differently. It had 37 pockets, with numbers fro 1 to 36 and a single zero, mimicking today’s European and French roulette wheel. Players would place their bets in the roulette table and wait for the outcome after the dealer had spun the wheel. The principle is the same with the modern roulette game, and in this guide, we’ll discuss how the roulette wheel and the roulette table casino work. We’ll discuss how many numbers on a roulette wheel, how it works, and discuss the differences between the European, French, and American roulette wheel.

Decoding Numbers and Colors on the Wheel

The roulette wheel includes numbers 1 through 36 in alternating red and black segments. The European version features a single green '0' slot, whereas the American variant introduces an additional green '00' slot. These green segments denote the house advantage. Grasping this configuration aids players in making strategic bets and understanding the mechanics of the game.

The Main Components of the Roulette Wheel

The roulette wheel layout, table, and the roulette board have undergone various changes and refinements over time - both in terms of design and gameplay. For example, American roulette brought the addition of another zero, which unlocked additional betting options. The advancements in manufacturing technology have contributed to the evolution of the game, with many new features being introduced to both the roulette wheel and the game itself.

Due to the implementation of new betting options and with a goal to improve player experience, the casino roulette table has undergone several changes as well, although it still retains the essential layout and functionality.

By being the centerpiece of the game, the roulette wheel is the most important part. Although it might seem simple at first sight, it’s actually rather complex and delicate. It consists of over 300 parts that have to be individually manufactured and fitted. The mechanics of every roulette wheel in the world are similar, although the choice of materials can vary depending on the manufacturer.

Nevertheless, high-quality materials are crucial for constructing a reliable and long-lasting roulette wheel. The most commonly used materials are wood, metal, and acrylic, but ultimately, the look is the same for all the classic roulette variants. These are all the essential components of every roulette wheel.

wheel components 1 2 3 4 5 6 7 8 9 10 11 12 13 14
  • 1.Turret - The turret is the top part of the roulette wheel, and the part that the croupier touches to rotate the wheel. It’s typically made out of wood and it often features decorative elements and/or branding.
  • 2.Turret base - The turret base is the lower part of the turret that holds the turret and provides stability and support.
  • 3.Height Adjuster - This is a moving part that allows for the turret to be adjusted in height.
  • 4.Wheelhead - The wheelhead is also known as the rotor, and that’s the spinning part of the wheel. It’s a central component of the roulette wheel that rotates during gameplay.
  • 5.Ball Pocket - The pockets are the numbered compartments on the wheelhead where the ball comes to rest after each spin. Each pocket is assigned a specific number, and the arrangement of numbers follows a predetermined sequence, alternating between red and black roulette colors.
  • 6.Frets - The frets are metal dividers or partitions that are located between the numbered pockets. They help to define each pocket and deflect the ball.
  • 7.Upper Bearing - The upper bearing is placed where the wheelhead connects to the turret, and it consists of a set of bearings or bushings that facilitate the rotation around the spindle axis.
  • 8.Cone - The cone is the part that directs the ball towards the middle of the wheel. As the name suggests, this part has a cone shape and has a major purpose in how the roulette wheel works.
  • 9.Ball Deflector - As the name suggests, this part has the purpose of deflecting the ball while it’s moving on the roulette wheel. If you’ve seen the white ball jumping around while the wheel is spinning, it’s due to the ball deflector.
  • 10.Ball Track - This is the place where the ball moves while it’s on the roulette wheel. It’s a groove or a channel around the edge of the wheelhead where the ball travels during gameplay. It provides a smooth surface for the ball to roll along and helps guide its movement as it loses momentum.
  • 11.Lower Ball Track - This is the lower part of the ball track, and the place where the deflectors are located.
  • 12.Spindle - The spindle is a central shaft that connects the wheelhead to the bowl and the part responsible for the smooth rotation of the wheel. It ensures that the wheelhead spins freely and remains securely in place while the wheel is spinning.
  • 13.Bowl Rim - This is the central metal part that’s beneath the bowl.
  • 14.Lower Bearing - This part is typically located at the base of the wheelhead, where it connects to the spindle. It consists of a set of bearings or bushings that allow the wheelhead to rotate freely around the spindle axis while minimizing friction and wear.
  • 15.The Bowl - It’s the stationary part of the wheel that holds the wheelhead in place. It contains all the numbered pockets and provides a stable base for the spinning action of the wheelhead.
  • 16.Centerpiece - This is not a mandatory part of the roulette wheel, but a decorative part that some wheels have. It’s at the center of the wheelhead, which may include the casino's logo, branding, or other decorative elements.

Comparative Chart of Roulette Variants Wheel & Table Configuration

The world of roulette features distinct versions like American, European, and French, each offering a unique gaming experience. The chart below delineates the principal distinctions in wheel and table configurations among these variants:

Aspect American Roulette European Roulette French Roulette
Number of Pockets 38 (1-36, 0, 00) 37 (1-36, 0) 37 (1-36, 0)
Inclusion of Zero(s) 2 (0, 00) 1 (0) 1 (0)
Special Rules - - La Partage, En Prison
Odds and Probabilities Lower Higher Similar to European

American roulette is notable for its 38 pockets, including two zeros, which reduce the odds and probabilities compared to its European and French counterparts. In contrast, European and French roulette feature 37 pockets with a single zero, yielding higher odds and a more favorable house edge. Additionally, French roulette introduces special rules like La Partage and En Prison, providing further benefits to players under certain conditions. Recognizing these differences can guide players in making informed decisions and customizing their strategies to each variant's distinct attributes.

American Roulette Wheel & Table

The American roulette wheel stands out from all of its popular counterparts, particularly the European and French roulette wheels. It features a unique layout and has one additional pocket - the double zero (00). This is a key distinction that has several implications regarding the betting options, RTP and house edge, and overall gameplay.

Even though the roulette table rules are largely the same, there are some differences, such as the added basket bet. "How many numbers in roulette" is a common question asked by players who are curious about the layout and mechanics of the wheel, so we are here to inform you that this variant has 38 numbers.

The total number of pockets is 38, and the house edge is 5.26%. This means that the Return to Player ratio for American roulette is 94.74%, which is slightly lower when compared to European roulette.

Another key difference is the roulette layout of the numbers. The two zeroes - the 0 and 00 pockets - are arranged opposite from one another on the roulette table wheel, while the roulette board layout of the numbers follows this sequence, starting from the single zero (0) and moving clockwise:

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

As you can see, the high roulette table numbers are often stacked one to another, which is slightly different than the European roulette wheel. Although this difference doesn’t affect the overall gameplay, it’s a notable difference for players who want to bet on specific advanced bets such as the Voisins, Cylinders, and similar announced bets. That’s why, in most cases, announced bets are not allowed in American roulette games.

While there may be some differences in the design and layout of American and European roulette wheels, however, particularly regarding the number of pockets and the presence of the double zero pocket, there are generally no significant disparities in build quality between the two versions. Both American and European roulette wheels are subject to stringent quality control measures to ensure fairness, accuracy, and durability in gameplay. Casinos and live casino roulette providers invest in high-quality roulette wheels from reputable manufacturers to provide players with a reliable and fair gaming experience regardless of the version of the game being played.

European Roulette Wheel & Table

The European roulette wheel is the most common one in modern casinos - both online and land-based. It’s preferred by most players due to the higher RTP and the lower house edge it has when compared to the American roulette wheel. This is due to the fact that the European wheel has 37 pockets in total, with only one zero (0). The Return to Player ratio is 97.30%, which is higher when compared to American roulette, and the house edge is 2.70%. Notably, though, the payouts are the same for all the different bet types as with American roulette.

Notably, this wheel is preferred by most software providers of live dealer games as well, and most live casino roulette games use the European roulette wheel and the classic European roulette rules.

Another difference when compared to the American roulette wheel is the numbers on roulette wheel are arranged. Namely, this is the sequence of how the numbers are arranged, starting from the zero and moving clockwise:

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

In comparison to the American roulette wheel, the numbers are distributed across the wheel in a predictable and symmetric way, and the high numbers are not very close to each other. This, and the fact that there’s a single zero, opens up several betting opportunities that are popularly known as announced or called bets. These are some of the announced bets you can make when playing European roulette:

  • Neighbors bet (Voisins du Zero): With the Neighbors bet, you’re betting on almost half of the roulette wheel. Namely, you will bet on the 8 numbers of each side of the Zero, including the green pocket, so the total number of numbers covered is 17.
  • Tiers (Tiers du Cylindre): The Tiers bet covers one-third of the wheel, specifically the numbers opposite the zero - which is how it got its name.
  • Orphans (Orphelins): This bet covers the remaining numbers on the wheel that are not included in the Neighbors and Tiers bets. It includes the numbers 1, 6, 9, 14, 17, 20, 31, and 34.
  • Zero Game (Jeu Zero): The Zero Game bet focuses on the 0 pocket, so it’s similar to the Neighbors bet. However, here, you’re covering just 7 numbers in total, so the potential payout is much higher.

These advanced bets are typically facilitated by the presence of a racetrack betting area on the roulette table layout, which allows players to bet on specific groups of numbers, including announced bets that are usually called out when playing in a land-based casino venue.

French Roulette Table & Wheel

Although many considered it a separate roulette variant, French roulette is actually very similar to European roulette. They use the same single-zero wheel with 37 pockets, and the roulette wheel numbers follow the same sequence. The payout ratios are the same for every bet type, and you can place all the same bets as with European roulette. The most significant difference between the two is the implementation of two unique rules that are only available with this variant: the En Prison and La Partage rule.

When active, both of these rules apply to even-money bets only, including Odds/Evens, High/Low, and Red/Black. Due to these rules, the house edge of French roulette drops to just 1.35%, and with an RTP of 98.65%, this is the roulette variant with the highest Return to Player ratio. This is how both of these rules work:

  • En Prison: This literally translates to ‘imprisoned’. But what does it mean? Well, if you make an even-money bet and the ball lands on the zero, you don’t immediately lose your bet like with all other roulette variants. Instead, it’s ‘imprisoned’ for the next round. You effectively place the same bet without placing a stake, but if your bet loses a second time in a row, you lose your stake.
  • La Partage: La Partage means ‘to share’ in French, and that’s exactly how this rule works. It also applies to even money bets, and if the ball lands on zero, instead of losing your wager, you split it with the house.
