American Roulette Wheel 

The American Roulette is a version of the game that has 38 total digits. Among all of the game’s variants, this is the one that gives the house the highest advantage of 5.26%. In this version, there are two green slots, with one zero and a double zero. The highest number on a roulette wheel is 37.

If you look at the wheel and start at the single zero, the order of the numbers on the roulette wheel

is as follows:

  • 0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1,
  • 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, 2

European Roulette Wheel

This is the classic roulette wheel layout used in many casinos. Unlike the American Roulette wheel layout, this one only has 37 digits. It only has one green slot where the Zero is placed. With this set-up, the house profit is 2.70%.

If you start counting the number in from the green slot clockwise, the order is as follows:

  • 0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10,
  • 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26

Bets Based on Wheel Sectors

The typical betting strategy in a casino for a roulette player is to place a wager on a number. But the game has evolved, and experts can call bets according to the groupings of the numbers. This kind of bet is called a “Call” or “Announced bet”.

They are only playable on the European roulette wheel and the French version of the game. Also, the Announced bet cannot be found on the betting table because the arrangement of the numerals are different between the betting table and the roulette disk.

If you bet your chips on a sector, you are not just betting on one number but a group of them, which means you need a huge capital to make this wager. The types of bets and the numbers they cover are:

  • Jeu Zero or Zero Game – 12, 35, 3, 26, 0, 32, 15
  • Voisins du Zero or Neighbours of Zero – 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, 25
  • Orphelins or The Orphans – 17, 34, 6, and 1, 20, 14, 31, 9
  • Tiers du Cylindre or Thirds of the Wheel – 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33.

ball lands on any of the slots covered by your sector, you win the corresponding prize for that number only.

The Logic of the Wheel

The numbers on the disk were not placed there randomly. It was carefully designed to make it balanced. It is like the arrangement of the letters on your computer keyboard — they are placed there because it is easier to type words that use a set or group of letters most of the time.

The sequence of the numbers is trying to accomplish the following things:

  • Confusion

It would be difficult to memorize the sequence and prevent gamblers from picking specific sectors. To the untrained eye, it looks random enough, and one cannot say that there is a bias in the game. If you order the numbers from 0 in ascending order, there is a big chance that a player will split that disk in his head into groups.

If he/she observes that the ball keeps on landing on a particular group, he/she will call it out and disturb the game. Thus, the player can make false accusations that the game is rigged, even if it is not. So to prevent this bias, the numbers were spread out in a specific fashion as it is much more difficult to create groupings if the numbers seem randomly arranged.

  • Proper Alternate Design

If you observe the wheel, red and black slots are alternate. No two colours are side by side. Next, the low and the high numbers also alternate. Low numerals are put beside high numerals to improve the balance of the spread of the numbers. The odd and even numerals are also spread out. In the European layout, you will not see more than two even numbers side by side.

Summary

Roulette is one of those games that have evolved over hundreds of years. Today, the wheels you see are carefully crafted and designed to provide the maximum balance in the game. What this means is that the results of where the ball drops are truly random.

If the black slots were put together, then winning would be a breeze as it is easier to land on either black or red, as there is a little possibility for the ball to skip that colour if it is already bouncing in that colour group. But if they alternate, the ball may still drop on black or red for as long as it is bouncing, so no one really knows what the outcome is going to be.
