Roulette is a casino game named after the French word meaning little wheel. In the game, players may choose to place bets on either a single number, various groupings of numbers, the colors red or black, whether the number is odd or even, or if the numbers are high (19–36) or low (1–18).
Roulette players have a variety of betting options. Placing inside bets is either selecting the exact number of the pocket the ball will land in, or a small range of pockets based on their proximity on the layout. Players wishing to bet on the ‘outside’ will select bets on larger positional groupings of pockets, the pocket color, or whether the winning number is odd or even. The payout odds for each type of bet are based on its probability.
The roulette table usually imposes minimum and maximum bets, and these rules usually apply separately for all of a player’s inside and outside bets for each spin. For inside bets at roulette tables, some casinos may use separate roulette table chips of various colors to distinguish players at the table. Players can continue to place bets as the ball spins around the wheel until the dealer announces no more bets or rien ne va plus.Croupier’s rake pushing chips across a roulette layout
When a winning number and color is determined by the roulette wheel, the dealer will place a marker, also known as a dolly, on that winning number on the roulette table layout. When the dolly is on the table, no players may place bets, collect bets, or remove any bets from the table. The dealer will then sweep away all other losing bets either by hand or rake, and determine all of the payouts to the remaining inside and outside winning bets. When the dealer is finished making payouts, the marker is removed from the board where players collect their winnings and make new bets. The winning chips remain on the board.
Types of bets
|Straight/Single||Bet on a single number||Entirely within the square for the chosen number|
|Split||Bet on two vertically/horizontally adjacent numbers (e.g. 14-17 or 8-9)||On the edge shared by the numbers|
|Street||Bet on three consecutive numbers in a horizontal line (e.g. 7-8-9)||On the outer edge of the number at either end of the line|
|Corner/Square||Bet on four numbers that meet at one corner (e.g. 10-11-13-14)|
On the common corner
|Six Line/Double Street|
Bet on six consecutive numbers that form two horizontal lines (e.g. 31-32-33-34-35-36)
On the outer corner shared by the two leftmost or the two rightmost numbers
A three-number bet that involves at least one zero: 0-1-2 (either layout); 0-2-3 (single-zero only); 00-2-3 (double-zero only)
On the corner shared by the three chosen numbers
|First Four||Bet on 0-1-2-3 (Single-zero layout only)||On the outer corner shared by 0-1 or 0-3|
Bet on 0-00-1-2-3 (Double-zero layout only)
|On the outer corner shared by 0-1 or 00-3|
Outside bets typically have smaller payouts with better odds at winning. Except as noted, all of these bets lose if a zero comes up.
1 to 18 (Low or Manque), or 19 to 36 (High or Passe)
A bet that the number will be in the chosen range.
Red or black (Rouge ou Noir)
A bet that the number will be the chosen color.
Even or odd (Pair ou Impair)
A bet that the number will be of the chosen type.
A bet that the number will be in the chosen dozen: first (1-12, Première douzaine or P12), second (13-24, Moyenne douzaine or M12), or third (25-36, Dernière douzaine or D12).
A bet that the number will be in the chosen vertical column of 12 numbers, such as 1-4-7-10 on down to 34. The chip is placed on the space below the final number in this sequence.
A special bet that covers the numbers 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, and 34. It has the same payout as the dozen bet and takes its name from the zigzagging, snakelike pattern traced out by these numbers. The snake bet is not available in all casinos; when it is allowed, the chip is placed on the lower corner of the 34 square that borders the 19-36 betting box. Some layouts mark the bet with a two-headed snake that winds from 1 to 34, and the bet can be placed on the head at either end of the body.
In the United Kingdom, the farthest outside bets (low/high, red/black, even/odd) result in the player losing only half of his/her bet if a zero comes up.
