Roulette is a queen of casino games. Roulette is so popular due to its luxury,passion and simple rules. The world 'roulette' means 'a small wheel' in French. It was Blaise Pascal who introduced the primitive version of this game in the 17th century. Frenchmen Francois and Louis Blanc invented the single "0" roulette game in 1842. In the 19th century casino gambling was forbidden in France, that's why the game wasn't so well-known in France, but it was very popular in Hamburg and Germany. Later Francois and his son Camille were responsible for bringing the game of Roulette back to southern France for the Prince of Monaco, Charles III. At the beginning of the 19th century Roulette appeared at American casinos and gambling houses. The improvements were deleted, and a double "00" returned. The game became popular in the old west of America.

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. Players have a few seconds after the dealer spins the wheel. No more bets can be made after the dealer says “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. He then removes all of the losing bets. Then the winning bets are paid off and the dealer removes the market from the Roulette table. Players are not allowed to touch their chips during this time, or else they could be removed from the casino. Try to be polite and 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.

Jagger’s Wheel.
Unbalance wheel is a good thing for unfair gamblers. They turn it to their advantage in order to make some fast cash. The only problem is that today it is impossible to find and unbalanced wheel. Casinos, too, have heard the story of Joseph Jaggers and are constantly monitoring their wheels. Before every table is open to the public the wheel is checked and rechecked to make sure it is perfectly balanced. In the case of an unbalanced wheel they recalibrate it at once.
2. The number that haven’t been hit yet is more likely to come out.
It is not so. The chances of hitting any number is 38:1. Just because the number seven has not hit for hours, does not mean it will hit soon. Remember roulette is a game of chance and the odds are the same for every number with every spin of the wheel.

The Martingale is the best-known roulette betting system. There are a great number of variations of it. The principle is following: 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 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.
