Here you can learn what all the terms and slang means when used in roulette. I can be a good idea to have a basic knowledge of roulette terms when reading roulette strategies so you easily understand them.
Types of Bets
These bets are so called inside bets, where you bet on numbers.
Straight (or Single) : a single number bet. 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 the 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 four numbers.
Six line (or Double Street): 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.
Trio: a bet on the intersecting point between 0, 1 and 2, or 0, 2 and 3 (single-zero layout only).
Basket (or the first four) (non-square corner): a bet on 0, 1, 2, and 3 (single-zero layout only).
Basket: a bet on 0, 1, and 2; 0, 00, and 2; or 00, 2, and 3 (double-zero layout only). The chip is placed at the intersection of the three desired numbers.
Top line: a bet on 0, 00, 1, 2, and 3 (double-zero layout only). The chip is placed either at the corner of 0 and 1, or the corner of 00 and 3.
Outside bets typically have smaller payouts with better odds at winning.
1 to 18 (Manque): a bet on one of the first low eighteen numbers coming up.
19 to 36 (Passe): a bet on one of the latter high eighteen numbers coming up.
Red or black (Rouge ou Noir): a bet on which color the roulette wheel will show.
Even or odd (Pair ou Impair): a bet on an even or odd nonzero number.
Dozen bets: a bet on the first (1-12, Premiere douzaine (P12)), second (13-24, Moyenne douzaine (M12)), or third group (25-36, Dernière douzaine (D12)) of twelve numbers.
Column bets: 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 sequence.
Snake Bet: Essentially a special dozen bet consisting of a bet of the following numbers: 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, and 34. Some gambling “experts”[who?] consider it a so-called sucker bet as they claim that the player has to bet a unit on each of those numbers, yet this theory (as with many gambling theories) is not true as any bet on the table has exactly the same house edge. However, some casinos which allow the snake bet (not all casinos do) allow the table minimum to be bet on the snake by placing the bet on the lower corner of the 34 spot which touches the 19-36 even money bet. On some layouts the “snake bet” is marked and depicted as a two-headed snake, with one head at one end of the “body” above and to the left left of the 1 and the other at the end of the “body” below and to the left of the 34. On these layouts the bet is placed on one of the heads.
