Roulette table layout

The roulette table layout at a glance

Every roulette layout, felt or on screen, has three zones. The number grid holds 1 to 36. The zero box sits at the head of the grid, holding 0 (or 0 and 00 on American tables). The outside area runs along the side and foot of the grid with boxes for the bigger group bets. Many online and European tables add a fourth zone, the racetrack, an oval that shows the numbers in wheel order for sector bets.

The grid is the key to everything. Numbers are laid out in twelve rows of three, counting across and then down: 1, 2, 3 in the first row, 4, 5, 6 in the next, and so on to 34, 35, 36. Each row of three is a street, and each of the three long lines of twelve is a column. Unlike the wheel order, which scatters numbers for balance, the layout keeps them in counting order so bets are quick to find. Our roulette hub links every bet covered here.

The roulette number grid, row by row

Here is the grid as it sits on a single-zero table, with zero above row 1. Each row is a street; the columns read downwards.

Notice rows 4 and 10, where two blacks sit side by side (10 and 11, 28 and 29). That is where the colour pattern flips: from 1 to 10 and 19 to 28, odd numbers are red; from 11 to 18 and 29 to 36, even numbers are red. The colours are the same on European and American tables.

What each column and dozen on the layout covers

Dozens split the grid crossways into thirds (rows 1–4, 5–8 and 9–12). Columns split it lengthways. Both cover 12 numbers and pay 2 to 1, and both lose on zero. But their colours don't split the same way.

Every dozen is split evenly between red and black, but the columns are lopsided. This is purely how the colours fall; it doesn't make any column more or less likely to win. A column is still 12 in 37 on a single-zero wheel, the same as a dozen bet.

Where to put chips for inside bets on the layout

Inside bets are placed on the grid itself, and the exact spot of the chip tells the croupier or software which numbers you mean.

A split can be sideways (17 and 18, in the same row) or lengthways (17 and 20, in the same column). Zero can be split with 1, 2 or 3 because it borders the first row. For the full details of each, see the straight up, split, corner, six line and basket and top line pages.

The outside betting areas on a roulette table

Outside bets sit around the grid, each with its own clearly marked box. They cover more numbers, so they win more often and pay less.

• Column boxes (often marked "2 to 1") at the foot of each column, beyond 34, 35 and 36.
• Dozen boxes (1st 12, 2nd 12, 3rd 12) running alongside the grid.
• Even-money boxes beyond the dozens: 1–18, Even, Red, Black, Odd and 19–36.
• On French layouts the even-money boxes may carry French names: Manque (1–18), Passe (19–36), Pair (even), Impair (odd), Rouge (red) and Noir (black).

On a single-zero wheel the even-money boxes win 18 times in 37 and pay 1 to 1; dozens and columns win 12 times in 37 and pay 2 to 1. All of them lose when zero lands, unless the table uses La Partage, which returns half of an even-money stake.

European, American and French roulette table layouts compared

The grid of 1 to 36 is the same on every standard table. The differences are at the head and in the extras.

The American zero box is the giveaway. If you see a 00 next to the 0, you're at a double-zero table and every bet costs nearly twice as much. Evolution's American Roulette (opens in a new tab) shows the 00 on both wheel and layout. See European against American roulette and European against French roulette for side-by-side costs.

The racetrack: a second layout for wheel bets

The racetrack is an oval printed or displayed beside the grid. It shows the numbers in wheel order rather than counting order, split into named sectors: voisins du zéro, tiers du cylindre and orphelins, with jeu zéro inside voisins. Tapping a sector places the full package of chips for that call bet on the main grid for you. Pragmatic Play's Mega Roulette (opens in a new tab), for example, lists racetrack bets for Zero Game, Tiers, Voisins and Orphelins.

The racetrack is a shortcut, not a different game. Wizard of Odds gives each call bet the same 2.70% edge as any other single-zero bet. The neighbours bet is placed here too: pick a number on the oval and it covers that number plus the pockets either side.

How to place a bet on an online roulette layout

1. Check the table limits shown in the corner of the screen or in the game information.
2. Pick a chip value from the chip tray at the bottom of the layout.
3. Tap the spot for your bet: a number, a line, a corner, a row edge or an outside box.
4. Tap again to add more chips to the same spot, or use undo to remove the last one.
5. For call bets, open the racetrack and tap the sector or number.
6. Check your total stake before the countdown ends; bets lock when betting closes.

Since 17 January 2025, autoplay is banned on all online casino games in Great Britain, but a re-bet button that repeats your last layout is allowed because you still press it every round. Non-slot games must also allow at least 5 seconds per game cycle, according to the Gambling Commission's speed of play decision (opens in a new tab). The £5 and £2 stake limits apply to slots, not roulette, so table limits are set by each game. Our guide to choosing table limits helps you match them to your budget.

Combining layout areas: does it change the odds?

The lopsided columns tempt some players into combination bets, such as black plus the middle column (which holds eight blacks). Here is what £10 on black and £5 on column 2 actually does on a single-zero wheel, £15 staked in total.

Average it across all 37 numbers: (8 × £20 + 10 × £5 + 4 × £0 − 15 × £15) ÷ 37 = −£15 ÷ 37, about −41p a spin. That is exactly 2.70% of £15. The overlap changes how often you win and by how much, but not the cost. The same is true of any spread on the layout, including so-called systems; see roulette betting systems and roulette myths.

Roulette table layout tips for new players

• Check the zero box before anything else: one zero is cheaper than two.
• Learn the row edge. Chips on the outer edge of the grid cover a street or six line, not a single number.
• When betting on a busy live table, confirm your chips have landed on the right line.
• Use the racetrack for sector bets rather than placing nine chips one by one.
• Remember that winning outside bets in a venue may stay on the layout for the next spin unless you collect them.
