The Table
Whether you're playing at a live casino or online, roulette tables have a distinctive layout. Though they might have slight design and style differences, all standard roulette tables have the same betting options and color schemes.
You make bets by placing chips on the spaces you think will win when the croupier spins the wheel. The distinctive American roulette table contains 50 betting spaces, laid out like so:
Numbers 1-36
These numbers appear in the main betting area, running left to right in ascending order, in three vertical columns on the main section of the table.
The following numbers are red: 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, and 36.
The following numbers are black: 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, and 35.
Numbers 0 and 00
In American roulette, these two numbers are colored green and appear at the head of the table, outside the layout for the 36 main black and red betting numbers.
The 2:1 Column Spaces
Located at the foot of the table outline, these depict the number column corresponding to each space.
The Dozens Spaces
Located at the left edge of the table in American roulette, these three spaces indicate the first, second, and last 12 numbers, situated into 3x4 numerical blocks to the immediate right of the space.
The 1-18 and 19-36 Spaces
In American roulette, these spaces are situated at the outside-most left edge of the table, located at the corners, opposite each other. Each betting space corresponds with the first or last 18 numbers in the main betting area.
Even and Odd Spaces
These areas sit opposite each other inside the 1-18 and 19-36 betting spaces.
Black and Red
Often displayed simply as a red diamond and a black diamond at the innermost two spaces on the left edge of the table, these diamonds symbolize a bet on red or a bet on black.
