===Outside bets===
Outside bets typically have smaller payouts with better odds at winning. Except as noted, all of these bets lose if a 0 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 [[parity (mathematics)|parity]]. [[Parity of 0|
Unlike in mathematics]], in Roulette 0 is considered neither even nor odd.
; Dozen bet: 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).
; Column bet: 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.
; Snake bet: 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 zig-zagging, 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 some casinos, the farthest outside bets (low/high, red/black, even/odd) result in the player losing only half of their bet if a zero comes up. This is known as the "halfback" or ''la partage'' rule. Others may use an "imprisonment" or ''[[en prison]]'' rule, wherein a loss on such an outside bet causes the player's money to be "imprisoned", and if the next spin would be a win for that bet, the player's wager is returned.
