Are All Roulette Wheels The Same? Roulette Layout & Numbers

Welcome to our latest blog post at Easy Slots, where today we're unravelling the mysteries of the roulette wheel - a staple of casinos both online and land-based. 

If you've ever wondered whether all roulette wheels are the same, what makes up their layout, the total number of numbers found on roulette wheels, or if there's any pattern to said numbers, you're in the right place. Designed for beginners and seasoned players alike, we're breaking down these intriguing aspects in a way that's easy to understand. Read on to learn more. 

What Is The Layout of a Roulette Wheel?

The layout of a roulette wheel is not as mystifying as it first appears. Primarily, there are two types: the European and the American. 

  • European Roulette Wheel: This variant features 37 pockets numbered from 0 to 36. The numbers are randomly arranged in a non-sequential order and alternate between black and red, except for '0', which is green. This layout is designed to distribute odds and evens, highs (19-36) and lows (1-18), and colours as evenly as possible. 
  • American Roulette Wheel: The American wheel adds a twist with an extra pocket, making 38 in total. Here, you'll find an additional '00' pocket, also in green, alongside the standard 0 to 36 numbers. This extra pocket slightly alters the distribution of numbers, but like its European counterpart, it aims for a balanced distribution of colours, odds and evens, and high and low numbers. 

Both layouts are meticulously planned to ensure a fair game, with the main difference being the American wheel's extra green zero pocket. 

How Many Numbers Does a Roulette Wheel Have?

The numbers on a roulette wheel differ depending on the wheel type: 

  • European Roulette Wheel: This wheel is adorned with a total of 37 numbers. It starts with a single '0', which is distinctly coloured in green, and then stretches from 1 to 36. 
  • American Roulette Wheel: The American version adds a slight twist by featuring 38 numbers instead of 37. Alongside the European setup, it includes an additional '00' pocket, also in green. This means the American wheel hosts numbers from '0', '00', and 1 through 36. The inclusion of the '00' pocket is the primary feature that distinguishes the American wheel, slightly altering the game's odds. 

Both versions provide a thrilling experience, with the number of pockets playing a crucial role in the game's dynamics and odds. 

Is There a Pattern To Roulette Wheel Numbers?

As the roulette wheel spins, the arrangement of numbers may seem random at first glance, but there's method to the madness. Roulette wheels are designed to strive for balance, especially concerning the outside bets - colours, odds and evens, and high and low numbers. 

  • Colours: You'll notice that red and black numbers alternate as much as possible, with the green pocket(s) for '0' (and '00' in American roulette) breaking up the sequence. 
  • Odds and Evens: Similarly, there's an effort to alternate odd and even numbers, although this isn't as strictly possible due to the wheel's layout constraints. 
  • Highs and Lows: Numbers are also arranged to balance high (19-36) and low (1-18) numbers across the wheel. 

This deliberate arrangement ensures a fair distribution of outcomes for outside bets, adding depth and fairness to the game's strategy so that none of the numbers within these bets are clustered. 

How Is a Roulette Table Laid Out?

The roulette table is a meticulously organised betting canvas designed to complement the wheel and offer a variety of betting options. At its heart lies the numbered grid, containing the numbers found on the wheel, except they're in numerical order. It contains the numbers from 0 (and 00 in American roulette) through 36, laid out in three columns and twelve rows. 

Surrounding this grid are boxes for outside bets - bets that cover broader categories of numbers for increased winning chances, albeit with lower payouts. These include: 

  • Dozens: Bet on one of three groups of twelve numbers (1-12, 13-24, 25-36).
  • Columns: Choose one of the three vertical columns, each containing 12 numbers.
  • Red/Black: Bet on the colour outcome of the spin, regardless of the number.
  • Odd/Even: Wager on whether you think the winning number will be odd or even.
  • High/Low: Decide if you think the ball will land on a low (1-18) or high (19-36) number.

This layout offers players a diverse range of betting options, from specific numbers to broad categories. This variety is one of the reasons roulette is so popular; you can tailor the game to your preference by choosing the type of bet you wish to place. 


In conclusion, roulette wheels come in two main variants: the European wheel with 37 numbers and the American wheel with 38, the latter distinguished by an extra '00' pocket. 

Despite their differences, both are designed with a meticulous balance in mind, alternating colours, and attempting to evenly distribute odd/even, and high/low numbers across the wheel. This careful arrangement aims to ensure fairness and unpredictability in the game, particularly affecting outside bets. Whichever you choose to play, understanding these nuances can help round out your knowledge of this classic casino game to better understand its workings. 

However, no matter which wheel you choose to play on, it's important to remember that each spin is an independent event, and the chances of the ball landing in any given pocket on a wheel are the same on every spin. Therefore, roulette is a random game of chance, and there's no way to guarantee a winning spin. Please gamble responsibly.
