How Does a Roulette Wheel Work?

3 min read

Roulette is a French name which means a small wheel. It is a gambling game where players bet depending on colours or numbers.  Players may opt to place a bet depending on a singular number or a group of numbers. Players also bet on whether a number is odd or even or if the colour is red or black. 

In other instances, players bet depending on high or low numbers. High numbers range between 19 and 36, and low numbers range between 1 and 18. This article will clearly explain how a roulette wheel works. 

European Roulette

This is also known as the French roulette wheel and has a single zero that corrects the effect of variance.

Just like in American roulette, the zero slots are coloured green, and the other numbers are divided into two. 

18 numbers are black, and the other 18 numbers are red. It has an advantage averaging to 2.7%. European roulette is the most common wheel with the maximum number of games played on it.

American Roulette

An American roulette wheel has 38 pockets in total and it has 00 as an additional number. There are 18 red pockets and 18 black pockets. Also, there are two green pockets numbered 0 and 00, placed on the opposite side of the device. One advantage of the American version is that it pays handsomely up to 5.26% since there is an additional slot numbered 00. 

Another difference between the European roulette and other roulette is the arrangement of numbers on the wheel.

Wheel Layout

In both American and European roulette, the order of the numbers on the wheel is different from their actual arithmetic sequence. 

This is meant to add to the confusion. As a result, it becomes very hard for a player to understand the relationship between numbers and sectors, which makes it even harder to win on a particular number or a sector. 

However, more experienced players find it easier to figure out the sequence of all numbers and sectors in their minds. The only way to grasp this information is to play more games so that the numbers become familiar.

  • Alternating Colours: Also, there are different colours on adjacent numbers. This further adds to the complexity of the visual arrangement and makes it harder to process the information.
  • Alternating Numbers:High numbers and low numbers alternate as much as possible. This, however, is not the case in the European roulette wheel between numbers 5 and 10. Under American roulette, many sectors following each other have low numbers or high numbers, making it of a perceived lower    standard compared to the European wheel.
  • Even Numbers And Odd Numbers: Odd numbers and even numbers are also distributed evenly. This means that there should be no more than two even numbers or odd numbers following each other.

The Wheel

The majority of casinos use a big wheel of diameter ranging between 25 to 32 inches. The balls are also proportional to the size of the wheel and its pockets. Casinos use small and big balls in a single day to confuse players. Casino balls are made of ivory or Teflon. 


The numbers and colours are mixed up to bewilder the players completely. This is because all businesses aim to make a profit, and casinos are no exception. By playing more frequently, youll get to know how the game goes, and you will have better chances of winning. Playing more games on roulette wheels gives you a chance to internalize the layout of the wheel. Try your luck at online roulette game
