How Many Numbers Does the Roulette Wheel have According to its Type?

The number of numbers that roulette has depends on the type of roulette it is.

  • French and European Roulette: it has a total of 37 numbers, ranging from 0 to 36. It is the most widespread roulette, and the most played in any casino. The house has an advantage of 2.7%.
  • American Roulette: it has 38 numbers, ranging from 0 and 00 to 36. The presence of the double zero gives an additional advantage to the banker.

Why do the Casino Roulette Numbers Have Such an Arrangement?

The arrangement of the numbers in the roulette wheel is not a whim, but a composition created by Blaise Pascal, its creator. This French mathematician created roulette with the aim of giving all participants the same chances of winning, while maintaining the same margin of opportunity for each one. It is a balanced layout that benefits all players equally.

However, Pascal's original design did not include 0 or 00, since at the time of creation there was no figure of the banker and only the players participated. The numbering does not follow any progression, that is, the numbers follow a random order. However, on the betting cloth they are placed in a rigorous order. This is due to the multiple bets and is intended to prevent the player from being able to use a single chip to bet on adjacent numbers on the betting mat and wheel.

Zero and Double Zero in Roulette

The 0 and 00 in roulette represent much more than just two numbers. The most important thing to keep in mind regarding the green squares of roulette is that, on the roulette table, you cannot bet on groups of numbers that include zero or double zero. These always go separately. This always gives an advantage to the house and the bank.

Now you know why the casino roulette numbers have this arrangement, and how this influences the odds of winning.
