Roulette is a wheel game. The wheel placed in a bowl spins on an axis. The wheel consists of 37 or 38 slots depending on the type of roulette:American roulette wheel contains 38 slots,European - 37.The numbers can be black or red. The 0 or 00 are green.Up to 8 people can play roulette at the same time.The rules suggest that the croupier spins the wheel of roulette in one direction and then rolls the ball around the edge of the wheel in the opposite direction.When the ball stops and falls at one of the slots the croupier announces the winners.You are to guess the number of the slot in which the ball will stop and to make the right bet. Before you start game, you buy chips from the croupier, and roulette chips are almost always different from all other chips in the casino. Each player is assigned his own color of chips so that the croupier knows who to pay off at the end of each spin. When the croupier announced "No more bets", hlayers cannot make bets.After the ball had stopped,the croupier puts a marker on top of the winning number on the table.If there are bets on that number,the marker is placed on top of the chips. The croupier sweeps off the table all losing bets and after that the winning bets are paid off.
We can find special rules for some casinos.

In Prison/En prison
When the ball falls on zero, red/black, odd/even and first half/last half bets will not be collected by the croupier - instead they will have to stay on the table - in other words they are in prison. In the next spin the players have a chance of winning their original bet back - if their bet wins they will get their original bet back but with no additional win. If the ball should land on zero once again the bets will remain in prison one more spin and so on. In prison rule is a considerable advantage for players because the house edge is reduced to 1.35%.

La Partage
In case the ball stops at zero slot, the croupier will not fully collect red/black, odd/even and first half/last half bets. The croupier will collect only a half of player's bets and will return the rest to the players. As well as the In Prison rule, the La Partage rule also reduces the casinos edge to only 1.35%.

The wheel is unbalanced.
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. But nowadays even if you try hard you will never find such a wheel. 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. If the casinos discover an unbalanced wheel, they immediately recalibrate it.
2. Another myth is that as more spins occur, players have a better opportunity of hitting a number that has not been hit yet.
This is absolutely false. Every number has the same chance of hitting-38:1. 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.

Today most gambling house odds are set by jurisdictions, and they have to be either 34 to 1 or 35 to 1. It means that the casino pays you or and you get to save your original bet.
The casino average or house advantage is the amount the player loses compared to any bet made. In case if a player bets on one number in the American game there is a possibility of 1/38 that the player wins 35 times the bet, and a 37/38 chance that the player loses.
The existence of the green squares are technically the only house advantage. Outside bets always lose in case if one or double zero come up. However, the casino also has an advantage on inside bets.
The house advantage should not be mixed up with the hold. The hold is the amount of money the table takes to change for chips, minus the chips taken away from the table. In other words, the actual "Win" amount for the gambling house. The Casino Control Commission in Atlantic City releases a monthly account showing the win/hold amounts. The average win/hold for double zero wheels is between 21-30%, more than 5.26%/2.70% of all players money since players are making repeated bets after winning and losing portions of their all money. It is called in the casino gaming industry as "Churning" and is mainly true of slot machine players who statistically end up losing all their bets.
A player with a certain total amount of money can not win or lose all his money very quickly, since the sum of all bets they make will be more than the sum of the money they really started with. The house advantage is applied to each bet made and not the all money. It means the player can end up losing much more than 5.26% of his original money.

There is a theory in the world of roulette that the roulette dealers are prepared at special school to throw the roulette ball in such a manner that the ball will stop on 0 or 00 on american roulette wheels. That assumption has been tried by some people who say it's real and that they know it is since they really visited such a school in order to find out. What for should "Croup" school train in it? Just hardly anyone wagers on 0 and double zero. Thus it is improbable for every spin to stop on zero or 00 still the ball may stop in the general zone of the 0 and 00.
If you have ever looked closely at a wheel you may have noticed something curious. You might have noticed that not only do the colors alternate the numbers as well alternate between even, odd, and high, and the 0 and 00 are crosswise from each other.
In the 12/6 playing system one is to pay attention to the numbers around the zero and double zero. First let's look at the 5 sections to the right of the 0 and the first 5 numbers to the right of the double zero that are 1, 13, 36, 24, and 3. These twelve numbers are the numbers which will make up your stakes. It is essential to remark that the numbers to the right of the zero and 00 are taken in case if the zero and double zero are at the head of the wheel from your vantage point.
So in the 12/6 playing system one will be laying split bets on the following numbers: 0, 00, 1, 2, 3, 4, 13, 14, 23, 24, And 35. These twelve sections that might be covered using 6 split bets are the reason for the title of this system. In case if you don'T know split stakes we'll offer you a quick refresher. A split bet is laying your roulette chip on the line separating the two numbers.
These bets include nearly a third part of the roulette wheel which indicates that you will almost have a one in three chance of winning on every spin. It is surely helped by means of the training of the croupier to attempt and hit those 0 and 00s. With the payoff of the split bets that is 17 to 1 you can get 1 of every 3 spins and nevertheless walk away having a nice small profit.
We advice that you begin the game at a table with a minimum bet of and when you win sum up the winning to the stake. Look for a busy table and choose a place near the center of the table. A dealer at a crowded table will perhaps take longer between spins and the center position will allow you to easily access your bets.
