The roulette table layout

The numbered grid

The conventional roulette layout places 1 through 36 in 12 rows of three numbers. Reading across the first row gives 1, 2 and 3, then 4, 5 and 6 in the next row. The three long columns contain 1, 4, 7 and so on, 2, 5, 8 and so on, and 3, 6, 9 and so on. Each column contains 12 numbers.

Lines and intersections

A chip inside a number’s box selects that number. A chip on a valid shared boundary selects a split. At an intersection of four numbered boxes it selects a corner. Street and six-line positions cover a complete row or two adjacent rows. Because placement carries meaning, a small movement can select a different group. Inspect the highlighted coverage before confirming a bet in a practice app.

Zero and the outside areas

The zero area sits at the end of the grid. American layouts include both 0 and 00. Dozens divide the numbered grid into 1–12, 13–24 and 25–36. Other outside areas group red, black, odd, even, low and high numbers. Zero belongs to none of those six groups. See bets and payouts for the corresponding payout sizes and the American first-five exception.

Table neighbors and wheel neighbors

Adjacent printed numbers are not necessarily adjacent pockets on the wheel. A split follows the table’s valid shared lines. A wheel-neighbor wager follows the physical pocket sequence instead. Check which kind of selection an interface is showing before using it. Begin with the first-round walkthrough, compare wheel variants and use the calculator for the probability of a selected standard group. This guide describes conventional layouts, while individual tables may use different orientation or special rules.

Read the grid in either orientation

A screen can rotate the felt without changing its rows and columns. The first four rows below show the pattern, which continues through 34, 35 and 36.

The 1–2 edge forms a split, as does 1–4. The intersection of 1, 2, 4 and 5 forms a corner. A street selects 1, 2 and 3 together; a six line selects 1 through 6. Diagonal contact between 1 and 5 does not form a conventional two-number split.

The first dozen spans these four rows and all three columns. A column instead follows every third number through the whole grid. Selecting a dozen and a column can cover shared outcomes. See overlapping bets before adding their probabilities.

Read the highlighted selection

Confirm its numbers and total stake before placing a chip. A racetrack shortcut may create several wagers at once rather than one chip where you touched. Its selection follows wheel order, which is separate from the grid. Zero-area placements can differ between single-zero and double-zero tables, so check the displayed rule instead of extending the numbered pattern into the green area.
