How does the Roulette Wheel work?

Roulette is a commonly found game at land as well as online casinos and has come to be identified as a game with a wheel of fortune. Basically, the Roulette game consists of two elements namely the wheel and table layout.

The Wheel – The game’s setup includes a wheel rotating on a circular base which is in turn divided into numbered compartments.

The Table – The table is laid out like a checkerboard of numbered boxes, in three columns and twelve rows, with the zeros at the top. The other boxes which allow the players to bet on a combination of numbers are laid out around the numbered grid.

Wheel Sequence

The numbering sequence on the two popular variations of the Roulette game i.e. American and European Roulette differ from one another in the positioning of the numbers on the wheel.

The Logic of Wheel Layout

The ordering of numbers on the Roulette wheel is in no way connected to their arithmetic value, instead, it is carefully designed to accomplish the below things at one shot.

  1. The numbers are arranged randomly with no relation between the numbers and the sectors, basically to confuse the players.
  2. The red and black coloured sectors are absolutely required to alternate on the wheel.
  3. The Low (1-18) and High (19-36) numbers are required to alternate as much as possible.
  4. The Even and Odd numbers are evenly distributed on the wheel, with not more than two even or odd numbers side by side.

American Roulette wheel

The American Roulette sequence goes as 0, 2, 14, 35, 23, 4, 16, 33, 21, 6, 18, 31, 19, 8, 12, 29, 25, 10, 27, 00, 1, 13, 36, 24, 3, 15, 34, 22, 5, 17, 32, 20, 7, 11, 30, 26, 9, 28 counter clock wise

European Roulette wheel

The sequence of the European wheel goes clockwise as 35, 12, 28, 7, 29, 18, 22, 9, 31, 14, 20, 1, 33, 16, 24, 5, 10, 23, 8, 30, 11, 36, 13, 27, 6, 34, 17, 25, 2, 21, 4, 19, 15, 32.

Parts of the Roulette wheel

The Diamonds

These are metal deflectors which are placed in various parts of the wheel to disrupt the path of the ball and are also known as disruptors.

The Ball track

This is a part on the outer rim of the circular base where the ball rolls. It is subject to wear and tear even though manufacturers take care to make it durable and as much crack free as possible.

The Rotor

This part is the inner part of the wheel which revolves with the compartments.

The Sectors

These are the pockets containing numbers into which the ball lands and the design of these are constantly modified.

The Base

This happens to be the outer part of the wheel, which is normally made from wood with a metal interior.

The Shaft

Also called as the spindle this is the shaft which supports the wheel rotor.

The knowledge of the wheel and the table layout goes a long way in helping the players to have a successful streak in the Roulette game.
