Winning at roulette

Player earnings

Bet on a number (straight) → 35 times the bet
Bet on two numbers (split – example: 7-10) → 17 times the bet
Bet on three numbers (street – also called “full cross”: eg 7-8-9) → 11 times the bet
Bet on four numbers (corner/square: example: 25-26-28-29) → 8 times the bet.
Bet on six numbers (six line/double street, also said “simple cross”: example: 13-14-15-16-17-18) → 5 times the bet
Bet on twelve numbers (dozen or column: example: 1-34 column or dozen 1-12) → 2 times the bet
Bet on a simple chance or eighteen numbers (Black – Red – Pair-Impair – Manque – Pass) → 1 time the ber
Bet on twenty-four numbers (two adjacent columns, the first twenty-four (1-24) or the last twenty-four (13-36), these bets being placed astride the columns or dozens) → half bet

When zero lost the bets placed on the many opportunities (that is to say, all bets on the numbers, from full to dozen). Bets played on simple chances:

in English roulette (most played in French casinos) lose half their value (the bank cautioned half)
in French roulette are “trapped” and the next draw determines if the player gets his bet (if its mere luck is taken) without payment, or if it is lost. If the next draw is a new 0, it will take two consecutive draws mere chance concerned that the player can recover his bet and so on.
in American roulette is lost. This is also true for the double zero (00)

These gains are rated out recovery of the original bet. That is to say, for example, for making “split”, you win 17 times the setting + the initial bet.

Another example: by betting € 2 in game on a number (build in “straight”) and the same number comes 70 € are earned and the initial bet (2 €) is recovered. So we get € 72 in total.

More generally, the gain is computed such that the expected value is zero for the game with 36 numbers; adding zero helps make the game favorable to the bank. This gain can be calculated by the following formula: where n is the number of winning numbers for the last question (straight, split, horse …).

Manque means betting on the numbers 1 to 18.
Pass means betting on the numbers 19 to 36.

Casino earnings

The casino collects all losing bets (unless resukts “0” where bets on simple chances are “imprisoned”)
In French roulette, there are 37 boxes, or the casino redistributes 35 times the stake (plus the bet itself) for the payment of a “atraight”.
In French online roulette, for the bets on straight number, the casino is paid not for the losses of the players, but for his earnings! The casino only pays 35 times the bet when there are 37 numbers. Zero is considered a misfortune by the player, as he is the artifice that allows the casino to take the “house advantage” it deserves. In reality, the player pays the casino when he wins, and when it loses its go to the “Pot”.

Game rules

Prior to the games

Before opening the game table, the dealer announces ostensibly in front of responsible for the game room and the chef, the account and the total of all the chips at face value of the bank roulette.

From that moment, when a player is in, the dealer openly announced that the English roulette table is open and that games are possible with the announcement: “Place your bets”.

Games

Since the announcement of the dealer “Place your bets”, all of the players around the table can make their bets.
The dealer catches the ball roulette.
It launches roulette in the opposite direction when she turned
He presses the ball against the channel surrounding the wheel and spear in the direction opposite the direction of rotation of the wheel. The ball shall be 3 rounds of the cylinder for the game to be valid
Before the ball does come experience one of the brass elements disrupting the path of the ball before falling into the roulette wheel, the dealer announces pointedly: “No more bets.”
Therefore, except under the direction of the dealer or his head, no bet may be placed.
As soon as the ball lands in one of the boxes, the dealer announces the winning number and the simple gains associated.
The dealer raises a weight, called dolly, on the winning number and performs payroll of winning bets. Gains “straight”, “split”, “street”, “square” and “six line” are announced openly and tokens are transmitted directly to players. Other payroll (columns, dozens and simple chances) are placed next to the wager value.
Made the paydays, the dealer withdraws the dolly number and openly announce “Place your bets”. Therefore, winning bets placed on the table can be taken by the players.

The above sequence is codified for the English roulette. It is much the same in the French roulette. However, in this latest version, there is no dolly, and one of the croupiers announces the winning number by pointing the box on the table with a rake.

Hazards

The ball falls in the cylinder between when the dealer catches it and its launch at the bottom of the rigole. The dealer announces ostensibly “No more bets.”

The dealer takes the ball and places it in the box corresponding to the previously released number without stopping the rotation of the cylinder
The dealer re-performs the faceoff procedure: taking the ball and change the rotation of the cylinder
As soon as the ball is rotated, the dealer announces pointedly that everything is ok

A player too far from a box launches token, but he can not or does not reach the desired position

The dealer asks the player to announces his bet. The dealer moves the token accordingly. He announced openly that he placed the token

The dealer or his head would check for a maximum bet wagers

The dealer announces pointedly: “I check the stake of …”. He removes the stake and place before him, he made the ostensible counting the number of tokens and replaces the stake. If chips are on-number, they are given back to the player.

The dealer checks the number of tokens for a payment

The dealer announces pointedly: “I withdraw the stakes … for the count.” He removes the weight, takes the pile of chips and places them in front of him. He pointedly counts down, and rests the chips on the box so that all players can verify afterwards the account and place the weight on the pile. It then performs the payment.

A player would make a token change while the ball rotates

The dealer announces ostensibly “Change after the game.” The payment finished, the dealer proceeds to exchange

The same number comes out twice

After announcing the winning number, the dealer announces pointedly that it is same number

The dealer makes a mistake (error in the payment, error in the announcement)

He gets orders from its leader and corrects his mistake.

Other rules

The dealer can not take anything from hand to hand. The player must first drop its token on the carpet before the dealer can take it.
The dealer must, before and after the launch of the ball or when he touched a token (for payment, investment or exchange), show the players that he has nothing in his hands.
In English roulette, in some casinos, it is indicated that the announcements are prohibited. This means that the player can ask the dealer to perform an entire placement obeying an announcement (for example, “the third in two parts”, “figure 9”). The dealer may however conclude a placement if and only if the player has started itself, then setting out orders like “fill in the third,” or “complete the figure of 9”.

Different types of roulette

(French Roulette “Caro Development”, https://commons.wikimedia.org/wiki/File:Roulette_casino.JPG)

French or European roulette, with a cylinder with 37 numbers, face value identical tokens to all players who are allowed unlimited. Usually, several sitting dealers perform the operations with rakes.
English roulette, which is identical to the French roulette, but operates differently (limited number of players, a token of color assigned to each player, one standing dealer animating the game table).
American roulette, which differs from the other 2 by the cylinder whose numbers are distributed differently and has a more issue: the double zero.
Mexican roulette, which is a replica of American roulette, but with a triple 0 surcharge.
German roulette, which combines features of the French and English roulette: the chips have face values, but each player can ask them to be differentiated (patterned chips: strips, peas etc.), and a single dealer standing animates the table.

Payment reports of the winning chances are the same for these 3 games, it is clear that Mexican roulette is the worst roulette for the player.

Martingale, betting systems

Mathematicians have explored different ways to beat roulette. These set of methods have different names: Martingale, delivery system, Hawks method, Labouchere method, method of D’Alembert, attack. Some of these methods allow to beat roulette: all differ and may require (theoretically) infinite wealth. Casinos have introduced setting limits (or maximum bet) to prevent the use of these systems therefore becoming inoperative. With a balanced roulette player expectancy of gain is always strictly negative.

A famous anecdote took place at the Monte Carlo Casino in Monaco August 18, 1913 which has been designated subsequently by the term bettor‘s error. On this occasion, the black color is out 26 times at the wheel, resulting in huge losses for players who were betting consistently on the red thinking that the probability of such a series is very low. Yet the probability is the same for each draw with less than 50% chance of seeing the ball settle on the black or the red (in fact, there is a green box, for 0, and 18 black and 18 red ).

Three call bets or announced bets are mainly used on the English and French roulette:

Voisins du zéro (neighbors of zero), played 17 numbers with 9 chips to place on horseback, cross and square (0/2/3-4/7-12/15-18/21-19/22-25/29 et 32/35).
Le tiers du cylindre (Thirds of the wheel), 12 numbers played with only 6 chips on horseback (5/8-10/11-13/16-23/24-27/30-33/36).
Orphelins (orphans, 8 numbers played with 5 chips (1-6/9-14/17-17/20-31/34).

Each announcement requested to the dealer will be placed “on horseback”, that is to say with the minimum of required pieces.
