Roulette Wheels and Tables: Learn The Differences In This Guide

Seeing a roulette wheel for the first time can look a little daunting to new players, especially if they are unfamiliar with the game’s rules. Additionally, the existence of several roulette variations makes the situation even more confusing. All of them feature different types of bets and odds, so players must familiarize themselves with each wheel and table layout.

In this article, we’ll look through the different wheel and table layouts of four roulette variations and touch upon the well-known announced bets.

All Roulette Wheel Layouts 

There are two different roulette wheel layouts — European and American. From European roulette emerged two spinoffs, namely French and triple zero roulette, with the two variants having additional double and triple zeros. The differences between them affect the odds and your gambling experience significantly. 

Although all types of roulette include the same number of red-black pockets, single zero roulette has a different average return than double or triple zero.

Below, we will explore the specific features of four roulette wheels.

European Roulette Wheel

The European roulette wheel has 37 pockets (numbers from 1 to 36 and a single green zero pocket). As there is no particular pattern to the sequence of numbers, predicting where the ball will land is more challenging.

When you look at the wheel, it appears as an odd-even pattern without any relation between the numbers.

In addition, the adjacent figures come in a red-black format, with no clear sequence. There is only one significant exception with 5 and 10, but the rest alternate between low (1–18) and high numbers (19–36).

Plus, the even and odd numbers are equally distributed, so two of either will never appear in a sequence.

American Roulette Wheel

The numbers also show random number sequences, so players can’t notice any discernible pattern.

French Roulette Wheel

French roulette is considered advantageous for real money players. This wheel resembles the European roulette wheel but has a lower house edge of 1.35%, thanks to its En Prison and La Partage rules, which are exclusive to this roulette variant.

The wheel has 37 divisions — from 1 to 36 and a green single zero pocket).

Triple Zero Roulette Wheel

The third zero raises the house edge from 5.26% to 7.69%.

Announced or Call Bets

Image of Announced or Call BetsAside from the standard inside and outside roulette bets, there is another category — announced bets, also known as call bets. Players place them on a racetrack, an oval-shaped area away from the main betting board.

Call and announced bets are similar in how they are both made on the racetrack and have to be announced. However, the difference is that the latter requires you to lay your chips down on the racetrack while announcing your bet, and the former doesn’t.

They are also known as French bets because of their names:

  • Jeu Zero
  • Le Tiers du Cylindre
  • Orphelins
  • Voisins du Zero

They require players to put chips down on different points on the racetrack to cover a series of numbers or even entire sections of them.

You must know where to lower your chips when making an announced bet. Some wagers are easier to perform and understand, like Tiers du Cylindre, which requires you to lay down the chips on six different splits. Orphelins is also a relatively simple bet. You must put one chip on number one (straight up), plus one chip each on four different splits. Jeu Zero covers seven numbers on the racetrack closest to zero. Players have a total of four chips where one is put on number 26 (straight up), and the other three on three splits each.

Other call wagers, such as Voisins du Zero, are more complex. It involves betting on 17 different pockets (numbers from 22 to 25), and its difficulty lies in the multi-chip trio and corner wagers.

Roulette Table Layout

All roulette table layouts have 36 numbers in 36 pockets, split into three columns of 12 numbers, with the addition of single, double, or triple zero squares sitting on top. The French version has a slightly different layout because it features bet names in French. Nevertheless, these minor differences don’t impact the return-to-player ratio.

You can place wagers on any of these squares and make different combinations. The squares are linked by the grid lines between them, so players bet on multiple consecutive numbers, two neighboring squares, and more. 

Additionally, the table consists of 18 red and 18 black numbers. You can place 50:50 wagers that the winning number will be black or red, odd or even. Plus, you can bet on low (1–18) or high numbers (19–36) or whether the winning number appears in a particular section. 

European Roulette Table Layout

In European roulette, the odds aren’t 35:1 but 36:1 once you add the green zero segment and get 37 pockets in total. This is where the casino’s advantage comes from. It is also possible to bet on the zero and return your chances to 35:1. However, if the zero wins, all bets on other numbers, red or black, odd or even, lose.

American Roulette Table Layout

American roulette has worse odds because the two-zero segment complicates things. As a result, your chances of hitting a number are 37:1 instead of 35:1, which is a significant disadvantage.

French Roulette Table Layout

On the other hand, French roulette favors players. There is one green zero pocket like in European roulette. However, the players have an advantage in French roulette because if the green zero wins, they do not necessarily lose their 50:50 wagers. As long as the La Partage rule is in place, players will receive half of their losing chips back.

Alternatively, if the En Prison rule is applied, all chips are locked in place for another spin. If you win, you get your chips back.

Number Sequences

Image of Number SequencesPlayers often find it confusing that the numbers on the wheel don’t follow a certain sequence. The scattered design makes it harder for players to keep track of the numbers they want to bet on.

Similar roulette wheel types have identical spreads of table numbers. Additionally, manufacturers and game developers do not determine the order.

In the case of American and European roulette wheels, numbers alternate evenly between red and black. However, the distribution goes beyond the colors since the wheel ensures a balance between high, low, odd, and even pockets.

In addition, there must be an alternation between high and low numbers. This distribution is better on the European wheel but still equally challenging to learn for new players.

What is the difference between the American and European wheels? There is a slight difference between the European and American roulette wheels.

What is the most popular type of online roulette wheel? The most popular is the French roulette wheel. There are two reasons for this — advantageous outside bets and the single-zero wheel, which has the fewest roulette numbers. Alternatively, gamblers will opt for European roulette with the same wheel type.
How should beginners approach roulette wheels? You should first understand the basic rules of the variant you want to play. In addition, you should place your bets during the available time period. Lastly, you should wait until the dealer spins the ball and distributes the winning chips if the ball lands on one of the winning slots.
