Roulette is a game of chance found in casinos around the world. Its name stems from the French expression for “small wheel”. The players at a Roulette table lay their wagers on either a single number or array of numbers, on black or red pockets, or even or odd numbers. The game starts when the dealer spins the wheel clockwise and the ball counterclockwise in the angled round path circling the wheel. If the ball falls in a pocket that matches the players’ bet, he wins. The European-style Roulette wheel has thirty-seven slots, whilst the American-style wheel has thirty-eight slots.

The origins of the game of Roulette date from eighteenth-century France.  The Roulette wheel is thought to originate from a combination of English, Italian and French board games. When the American Roulette wheel was first invented, it had the numbers one through twenty-eight with a single zero, a double zero and a bald eagle in its slots. In the early nineteenth century, roulette gained widespread fame in the casinos all over the world.  In the 1860s, Monte Carlo has become the center of gaming for the higher European social classes, where single-zero Roulette became the most popular casino game.  At the same time in the Western Hemisphere, double-zero roulette continued rule the market. Now, numerous players call Roulette “King of the casino games” due to its historical connection to the fashionable casinos of Monte Carlo. By the start of the twenty-first century, Roulette has been established in hundreds of casinos.

The game of American Roulette game typically uses a double-zero wheel. This variety of the game strays from the conventional French style and is a very easy version. Pockets on the roulette wheel are numbered one through thirty-six, with the two green pockets labeled “0″ and “00″.   Roulette games have set amounts for the lowest and highest bets permissible.  Players make ‘inside’ and ‘outside’ bets on their chosen numbers. Payouts for each scenario are based on its odds. For “inside” bets, the dealer may use a variety of colored chips to differentiate between the players.

A Roulette table’s cloth that displays the bets is called a “layout”. French-style roulette tables have one zero and American-style “layouts” have zero (“0″) and double zero (“00″). On American Roulette tables, the wheel is located at the end of the table, while the French tables station the wheel in the middle of the table with “layouts” on the sides.  This style of “layout” is seldom seen away from Monte Carlo. Roulette bets come in a variety of classes. Straight, Split, Street, Corner, Six Line and Trio bets are all of the major “inside” bets (bets placed “inside” the layout grid).  “Outside” bets (bets placed “outside” the grid) have better odds to win, as do the “dozens” and “columns” bets.

At first, the set-up the early gambling houses used was to put the odds at 27:1.  In recent years, the casinos have set the odds at 34:1 or 35:1. The money that each player loses over the long run is called the “house advantage” or “house edge”. The green slots on the roulette table symbolize this advantage.  Players can bet a fixed amount during play or can bet various amounts in different spots on the layout.  However, some casinos may have different betting rules.
