Among all the casino games roulette is classic. In any full service casino in the United States besides blackjack and craps you'll find roulette which is more popular in France where it is historically a cultural part of the gambling scene. Roulette was popular in Europe since the 18th century and today it is played online all over the world.Modern roulette has been around since at least 1796, when the game was played in Paris in almost exactly the same form it's played today. Multiple games gave birth to roulette. An Italian ball game called "biribi" was also popular in France in the early 18th century, and it was combined with another wheel game that involved colors but not numbers to make a modern roulette game. The English game "Roly-poly" which consisted of black and white slots was launched in 1720. So we can consider roulette a fusion of birib and Roly-poly.Understanding a game is the first step down the road of enjoying a game. And although knowledge of the game won't change your strategy or your chances of winning, it will increase the amount of pleasure you take away from the tables.

There is also the European wheel or the Single Zero roulette or sometimes French Rouletteis similar to the American wheel.
The greatest difference between the European and the American wheel is the fact that European wheel only has a single zero - whereas American wheel has a single zero and a double zero.
The European table is more beautiful in symmetry while the American table is more practical during play because the red/black and odd/even are placed right next to each other, and the first18/last18 betting spots are placed right next to the single numbers.
The European single zero offers the player better odds than the American wheel with it’s single and double zero.
American roulette wheel is divided into 38 numbered slots:numbers 0 to 36 and 00. The betting layout consists of every individual number as well as a host of "outside" or combinations of numbers. After the players make their bets the dealer spins the wheel and a ball and after several seconds the ball will land in one of the numbered slots.

As a gambler you know that when playing Roulette there is a certain period of time in which you can make bets. In between each spin of the wheel, the dealer normally gives all of the bettors about 60 seconds to place their bets. When the dealer spins the wheel, you still have a few seconds to place a bet. As soon as the dealer raises his hand and says “no more bets” players can make no more bets. After the spinning ball lands in one of the pockets, the dealer will put a market on the corresponding number on the table. Then all the losing bets will be removed from the table. After that, he will pay off the winning bets, and remove the marker from the table. Players are not allowed to touch their chips during this time, or else they could be removed from the casino. Above all else, just be courteous. Make sure that you are respectful to the dealer and the people around you, and also offer the dealer a small tip every 10th spin or so. The last advice here is avoid drinking alchocol.

One of the most popular betting systems in roulette is the Martingale. There are a great number of variations of it. The main idea of the system is that when you win, you pocket your bet. But when you lose, you double the size of your previous bet.By doing this in case you win, you get back your previous loss and one more unit.And so on.
The Martingale System works great only in case you have an infinite bankroll and no betting limits.
Another popular roulette system is the d'Alembert system. This system assumes that after a win, a player is less likely to win again.So after a win, you subtract a chip from your bet. The d'Alembert system also assumes that you are less likely to lose after a losing spin, so in that case, you add a chip to your bet. The fact that the roulette wheel has no memory and each spin is an independent trial with exactly the same odds of a win or loss is the previous spin is a weak point of the system.

The numbers 1 through 36 are divided evenly among red and black "pockets" on the Roulette wheel. The pocket is an area, in which the ball can land. In addition to the 36 red and black pockets, there are either 1 or 2 green pockets, containing the number zero and double zero (00) on the roulette wheel.
A roulette dealer (usually referred to as "croupier" spins the wheel counter clockwise and releases what is usually a plastic ball along the track that runs along the top of the wheel's cavity. The wheel loses speed and as a result the ball comes down from the track, bounces a little and then lands in one of the pockets.
