Wheel Layout

The pockets are numbered from 1 to 36, alternating between red and black. There is a green pocket numbered 0. In American roulette, there is a second green pocket marked 00. Pockets are not in numerical order around the wheel. Some consecutive numbers are the same color.

Types Of Bets

Inside Bets :
• Straight: a single number. The chip is placed entirely on the middle of a number square.
• Split: a bet on two adjoining numbers, either on the vertical or horizontal (as in 14-17 or 8-9). The chip is placed on the line between these numbers.
• Street: a bet on three numbers on a single horizontal line. The chip is placed on the edge of line of a number at the end of the line (either the left or the right, depending on the layout).
• Corner (or square): a bet on four numbers in a square layout (as in 11-12-14-15). The chip is placed at the horizontal and vertical intersection of the lines between the numbers.
• Sixline (or 'sixaine'): a bet on two adjoining streets, with the chip placed at the corresponding intersection, as if in between where two street bets would be placed.

Outside Bets :
• Even Money Bets: a bet on 18 numbers. This is placed in the box representing the attribute (black/red/low/high/even/odd) that you wish to bet on.
• Group Bets: a bet on the first, second, or third group of twelve numbers.
• Column: a bet on all 12 numbers on any of the three vertical lines (such as 1-4-7-10 on down to 34). The chip is placed on the space below the final number in this string.

House Edge

The house average or house edge (also called the expected value) is the amount the player loses relative to any bet made, on average. If a player bets on a single number in the American game there is a probability of 1/38 that the player wins 35 times the bet, and a 37/38 chance that the player loses their bet. The expected value is:
-1*37/38 + 35*1/38 = -0.0526 (5.26% house edge)

For European roulette, a single number wins 1/37 and loses 36/37:
-1*36/37 + 35*1/37 = -0.0270 (2.70% house edge)

In roulette the house has the same edge on all other kinds of bets also, because the pay outs are always set as if the zero square(s) did not exist. The only exception are the five numbers bet where the house edge is considerably higher (7.89% on an American wheel) and the 'even money' bets in the some European games, where the house edge is halved because only half the stake is lost when a zero comes up.

The house edge should not be confused with the hold. The hold is the total amount of cash the table changes for chips, minus the chips taken away from the table. In other words, the actual "win" amount for the casino. The Casino Control Commission in Atlantic City releases a monthly report showing the win/hold amounts for each casino. The average win/hold for double zero wheels is between 21-30%, significantly more than 5.26%/2.70% of all players money because players are making repeated bets after winning and losing portions of their total money. This is known in the casino gaming industry as "churning" and is especially true of slot machine players who usually end up losing all their money.

A player with a certain total amount of money may not win or lose all their money instantly, such that the total of all bets they make will often be greater than the total of the money they actually started with. The house edge applies to each bet made; not the total money, which means the player can end up losing significantly more than 5.26% of his starting money. For example it is likely that a player with $100 making $10 bets on red will be able to bet more than 10 times, because sometimes he wins. He may end up betting a total of 20 times on red. This means the expected value is 20*$10*5.26% = $10.52, over 10% of his money is now in the 'hold' despite the game having a 5.26% house advantage. A player who continually bets until they run out of money will give the house 100% hold.

Called (Or Call) Bets

There are a number of series in roulette that have special names attached to them. These are placed by betting a set amount per series (or multiples of that amount). They are based on the way in which certain numbers lie next to each other on the roulette wheel. Not all casinos offer these bets, and some may offer additional bets or variations on these.

Voisins Du Zero ("Neighbors Of Zero") :
This is a name for the numbers which lie between 22 and 25 on the wheel including 22 and 25 themselves. The series is 22,18,29,7,28,12,35,3,26,0,32,15,19,4,21,2,25 (on a single zero wheel).
9 chips or multiples thereof are bet. 2 chips are placed on the 0,2,3 street; 1 on the 4/7 split; 1 on 12/15; 1 on 18/21; 1 on 19/22; 2 on 25/26/28/29 corner; and 1 on 32/35.

Tiers ("The third") :
This is the name for the numbers which lie on the opposite side of the wheel between 27 and 33 including 27 and 33 themselves. The series is 27,13,36,11,30,8,23,10,5,24,16,33 (on a single zero wheel).
6 chips or multiples thereof are bet. 1 chip is placed on each of the following splits: 5/8; 10/11; 13/16; 23/24; 27/30; 33/36.
A variant known as "Tier 5,8,10,11" has an additional chip placed straight up on 5, 8, 10 and 11; and so is a 10-piece bet.
This is also called the "Small Series" It includes the following wagers which are all Splits
5/8, 10/11, 13/16, 23/24, 27/30, 33/36

Orphelins ("Orphans") :
These numbers make up the two slices of the wheel outside the Tiers and Voisins. They contain a total of eight numbers, the Orphans comprising 17,34,6 and the Orphelins being 1,20,14,31,9.
5 chips or multiples thereof are bet. 1 chip is placed straight-up on 1 and 1 chip on each of the splits: 6/9; 14/17; 17/20 and 31/34.

"xx And The Neighbors" :
A number may be backed along with the 2 numbers on either side of it in a 5 piece bet. For example, "0 and the Neighbors" is a 5 piece bet with 1 piece straight-up on 3, 26, 0, 32 and 15. Neighbors bets are often put on in combinations, for example "1, 9, 14 and the neighbors" is a 15 piece bet covering 18, 22, 33, 16 with 1 piece; 9, 31, 20, 1 with 2 pieces and 14 with 3 pieces.
Any of the above bets may be combined, eg "Orphelins by 1 and Zero and the Neighbors by 1." The "...and the Neighbors." is often assumed by the Croupier
