In roulette everything depends on chance. Trying to keep the house edge to a minimum is almost all you can do from a strategic point of view. There are special rules in casinos which directly affect on the edge.
The first strategy in roulette is the 'surrender' option. This rule is applied to outside bets such as odd/even, red/black, and high/low. In case the ball falls on 0 or 00 you lose half your bet,but not the whole betting. This affects the house edge considerably; after all it is the 0 and 00 which account for the high house edge in the first place. Even though the payoffs aren't as great for outside bets,you are improving your odds substantially by finding a table with the ‘surrender' rule.
Rather interesting point is the 0 and 00. It is better that you look for tables with only one 0 - European tables. Primarily found in Europe, these tables offer a much more attractive house edge from the player's point of view. With a European table to play on you are reducing the house edge from 5.26% to 2.7%. Physically European roulette tables are found more often in Europe, but in the ‘online world’ gambling they are just a click away.

Casino is mostly associated with roulette. Roulette is so popular due to its luxury,passion and simple rules. If you translate the word of “Roulette” from French you will get “small wheel”. It was Blaise Pascal who introduced the primitive version of this game in the 17th century. Later the single zero Roulette appeared. It was introduced by Francois and Louis Blanc. The game wasn't then very popular in France as any form of gambling was considered illegal, but Roulette was well-known in Germany and Hamburg. Later the game of Roulette was brought back to France and the Prince of Monaco loved this game a lot. 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.

Roulette is a wheel game. The wheel placed in a bowl spins on an axis. The wheel is divided into slots: American roulette wheel into 38, European - into 37.The numbers can be black or red. The 0 and 00 are considered green.8 players can participate the game at the same time.Accordind to the rules 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.After the ball had fallen at one of the slots and stopped, the croupier announces the winners.The aim of roulette is to guess the number of the slot in which the ball will stop and to make the right bet. When you first sit down at a roulette table, you'll need to buy chips from the croupier, and roulette chips are almost always different from all other chips in the casino. Each player has chips of his own color that's why the croupier knows who to pay off at the end of each spin. A player is allowed to bet until the croupier announces, "No more bets."After the result of the spin is determined, the croupier puts a marker on top of the winning number on the table.The marker is placed on top of the chips, if there are bets on that number. Then all losing bets are swept off the table before the winning bets are paid off.
Some casinos have special rules.

In Prison/En prison
In case the ball stops at zero slot, the croupier will not collect red/black, odd/even and first half/last half bets, they will 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. As this special rule reduced the casinos edge, it's greatly to the advantage for the players.

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%.

One question that usually arouses if people consider winning at the game of roulette is biased roulette wheels. To truly discover a bias in a wheel, you'D be required to clock at least 4000 spins before determining a real pattern, and realistically speaking, you won't find a bias towards red or black. At best you'Ll find a bias toward a particular group of sections.
Casinos don't wish to have a biased roulette wheel, because the casino edge at the game of roulette relies on the odds making up 37:1 For every number over time. When certain particular numbers appear more often than they are to, the gambling house loses money. Gambling houses don't in fact have any benefit in fixing any games because the casino edge is in their favor on all of them. If you are able to find a biased roulette wheel, you should bet specific numbers. In case if you're in a situation where you get an advantage over the casino, you don't want to dissipate it on stakes with small winnings.
One thing resembling wheel bias croupier signature. Some roulette dealers have been spinning the ball for so long that they do it in exactly the same manner and at exactly the same speed every time. This produces a situation where a group of numbers can come up much more often than others.
So if you're trying to find that kind of advantageous playing it's best to find an older croupier who looks really bored, as if he has been doing it for long. You don't wish one who's rather inexperienced and simply learning in what way to spin the wheel. You want somebody who's spun it that many times that it has got instinctive and expected.
As this would take about 4000 spins to determine some patterns on a roulette wheel, that would require a considerable amount of time to trace that many spins. Perhaps 100 hours or so. You would be better off learning to count cards or play poker really well instead of attempting to gain advantage looking for a biased wheel or a croupier having a signature.

Today most gambling house odds 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 (also called the expected value) is the amount the player loses compared to any bet made, on average. 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 green squares on the Roulette wheel and on the table 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 since the pay outs are always set at 35 to 1 in case if you mathematically have a 37 to 1 probability at winning a straight bet on one number.
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. 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%, much more than 5.26%/2.70% of all players 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 bets they make will often be more than 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.

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. Depending on the Roulette variation there is one or two green pockets with 0 or 0 and 00.
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. As the wheel loses velocity the ball is pulled down off of the track and bounces around until it settles into a pocket.
