In the world of casino games, roulette is a classic. Roulette is an obligatory element, along with blackjack and craps,in any full service casino in the United States, but in France it's much more popular as roulette is a cultural and historical part of the gambling scene. Roulette was popular in Europe since the 18th century and today it is played online all over the world.Roulette was played in Paris since 1796 and nowadays it almost has't changed. Roulette had its origins in multiple other games. In the early 18th century in France was popular "biribi" - an italian ball game which was combined with another wheel game where colors, not numbers were used. In 1720 in England people began to play "Roly-poly" which consisted of black and white slots. So roulette could possibly be considered a hybrid of both birib and Roly-poly.To understand a game is to enjoy it.Only in case you understand game you can enjoy it. 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.

Every gambler knows that he can make bets during a certain period of time. In between each spin of the wheel, the dealer normally gives all of the bettors about 60 seconds to place their bets. Even after the spin of the wheel you have a few seconds to make a bet As soon as the dealer raises his hand and says “no more bets” players can make no more bets. When the balls drops into a slot on the roulette wheel, the dealer will place a marker on the table that corresponds with the slot that the ball dropped into. Then all the losing bets will be removed from the table. Then the winners get paid and the marker is removed from the table. After the stop of the ball nobody is allowed to touch the chips. Otherwise he can be femoved from the table. 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.

The wheel is not well balanced.
Of course there always exists a chance that the wheel is not balanced well. That’s why there are unfair gamblers who use it if they notice that the wheel is unbalanced. The truth is the unbalanced roulette wheel no longer exists. The story of Jaggers is well-known among casinos, that’s why they examine the wheels all the time. The wheel is checked several times before it is open to public. In the case of an unbalanced wheel they recalibrate it at once.
2. Most gamblers believe that with every new spin the chances of the ball landing in the number that has not been hit yet become much higher.
This is absolutely false. The probability to hit a number every spin is the same 1 out of 38. If the ball hasn’t landed in this very number for a long period of time it doesn’t mean that it is more likely to do it in a short while. Roulette is a pure game of chance. With every spin the chances of hitting any number are 38:1.

One of the most popular betting systems in roulette is the Martingale. It varies greatly. You should follow such principle: if you win, then 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 are not limited in your bankroll and betting.
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.
When all bets are made the dealer spins the wheel counter clockwise and then the ball is released along the track. 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.
