How Many Numbers Are On A Roulette Wheel


Roulette is a game of chance played with a spinning wheel. The wheel is divided into 37 compartments, numbered 0-36, and is the same size for each one. In European wheels, there are no zeros. For American wheels, there is both a single zero (0) and double zero (00).

The number of slots or pockets on the wheel determines the type of roulette. European Roulette has 37, French Roulette has 37, and American Roulette has 38 pockets. For even money bets, the house edge is two point seven percent across all types of roulette. This means the house will always win a certain amount from each bet placed at the roulette table. For example, on an American roulette wheel, it would be five point twenty six percent for bets other than single zero or double zero.

The numbers around the outside rim of a typical roulette wheel are given values between 0 and 36. Some have an extra ‘double 00’ compartment, which is green. This changes odd/even bets, as zeros occur more often due to their doubled nature. This gives them less chances than other slots in terms of probability gaming results. The house edge takes more money and gives low returns when they hit, due to their doubled interest rate gain.

Number of Numbers on a Roulette Wheel

Roulette is a famous casino game. No wonder why there’re many versions of it! A roulette wheel’s key feature is the number of numbers appearing on it. Though they may differ, most roulette wheels have 37 or 38 numbers.

Let’s investigate further the number of numbers on a roulette wheel:

American Roulette Wheel

American roulette is the popular game of Las Vegas casinos. It uses a layout of 38 numbers – 0, 00, and 1 to 36. All the red numbers are next to the black numbers, creating the “red/black” symmetry. These numbers are placed evenly.

When playing American roulette, you can wager on one or more numbers (1-36), zeroes (0, 00), or a range of numbers. For example, you can bet on one number, two numbers (“split“), three (“street“), four (“corner“), six line (“six-line“), or twelve adjoining numbers (“first dozen“, “second dozen” or “third dozen“).

European Roulette has 37 slots numbered from 0-36, since it has only one green zero instead of two. The strategy for playing each vary as there’s no double zero option in European Roulette. This changes the payout calculations for this version.

European Roulette Wheel

The European roulette wheel is the most popular one found in casinos. It has 37 slots, numbered 1-36 and a single green 0. The other numbers alternate between black and red.

This combination of a single green 0 plus the even distribution of black and red pockets decreases the house edge, compared to American roulette.

Many casinos offer half the bet back if the ball lands on 0. This significantly reduces the house edge, particularly when betting on ‘even money’ like red/black or odd/even.

French Roulette Wheel

In Roulette, the wheel has 37 pockets. French Roulette has the same layout as American Roulette but with one zero pocket and one double zero pocket. This makes the game more unpredictable and increases the house’s edge.

European Roulette follows the same rules as French Roulette but with only one zero pocket. This gives players better chances of winning than with French Roulette which has two zeros.

American Roulette has 38 pockets; two zeros and numbers one to 36. This gives players unequal odds and a bigger house advantage than European or French Roulette wheels.

Number of Bets That Can Be Placed on a Roulette Wheel

A Roulette Wheel is filled with numbers. 0 to 36. Half of them red, the other half black. The 0 is green. You can bet on the slots and also on different sections of the wheel.

Let us explore the types of bets you can make:

Inside Bets

When playing roulette, you can choose an inside or outside bet. Each has its own betting box. Inside bets include numbers, groups of numbers & special characteristics. There are nine types of inside bets:

  • Straight Up: Bet on 1 number including 0 & 00.
  • Split Bet: Bet on 2 numbers; winnings at 17 to 1.
  • Basket Bet: Wager on 0, 1, 2 or 0, 00, 2; 6 to 1 winnings.
  • Street Bet: Bet on 3 consecutive numbers; 11 to 1 winnings.
  • Corner Bet: Cover 4 numbers; 8 to 1 winnings.
  • Six Line Bet: Bet on 2 streets; 5 to 1 winnings.
  • Trio or Basket Bets: Cover 3 incl. 0 or 00; 11/1 winnings.
  • Quad Bets :Cover 4 numbers as double street; 17/1 winnings.
  • Top Line Bets : Bet on 0, 00, 1 & 2 or 3; 6/1 winnings.

Outside Bets

Roulette has two kinds of bets, inside and outside. Inside bets are on the numbers on the board, 1-36 and a 0 or double 0 if it’s American roulette. These are higher risk, higher reward.

Outside bets don’t use any specific number and you bet on groups of numbers or colors. One type of outside bet is the dozen bet on 12 numbers. That covers 1/3 of all possibilities. Another is an evens or odds bet which covers all odd or even numbers. Other common bets include low or high numbers, red or black, and column/dozen/street bets with 12 options.

Most tables have minimum and maximum amounts for each spin. It’s in bold above the wheel. Some online roulette games let you make multiple outside bets on one spin to up your chances of winning. Check your local casino’s gaming regulations for more info. Generally, there’s no limit on how many outside bets you can make in one spin.


A roulette wheel usually has 37 numbers, including 0 and 00. This is the most regular type and is used in both American and European casinos. The European roulette has just one 0, while the American has two. Knowing which table you play on can help you bet more effectively. Some systems work better on certain wheels.

If you’re unsure of the game version, look for the 0 or 00 to figure out your odds.
