Roulette rules

Roulette drops a ball on a spinning wheel, and you bet on the number of the pocket where it stops.

Updated:2026-10-03

Key points

  • You bet on the number where the ball will stop, and a win pays out.
  • Bets range from a single number to red or black, and the fewer numbers a bet covers, the more it pays (a single number pays 35:1, red or black 1:1).
  • Zero is neither red nor black, so even-money bets such as red, black, odd and even lose when it comes up.
  • The house edge is 2.70% at a single-zero table and 5.26% at a double-zero table (0 and 00).

How a spin goes

  1. Place chips on the layout. Players are responsible for placing them correctly
  2. The dealer spins the ball against the direction of the wheel
  3. While the ball is spinning the dealer calls “No more bets”. No bets after that
  4. The winning number is announced and a marker (the dolly) is placed on it
  5. Losing bets are collected, then winners are paid

The numbers are 1 to 36 (18 red, 18 black) and a green 0. Tables differ in how many zeros the wheel has and in what happens when zero comes up (Zeros and zero rules).

Signals and etiquette

  • Roulette chips have no printed value. Each player gets a color, worth the buy-in divided by the number of chips. You cannot use the same color as another player at the table
  • Once “No more bets” is called while the ball spins, do not place bets
  • A marker (the dolly) goes on the winning number, losing bets are collected, then winners are paid
  • Check yourself that your chips are placed where you intend

Bets and payouts

A bet pays “36 ÷ numbers covered − 1”. Every bet has the same house edge; only how often it wins and how much it pays differ.

Bet Numbers Pays Chance to win (single zero)
Straight 1 35 2.70%
Split (two neighbors) 2 17 5.41%
Street (one row) 3 11 8.11%
Corner (four at a corner) 4 8 10.81%
Six line (two rows) 6 5 16.22%
Dozen, Column 12 2 32.43%
Red/Black, Odd/Even, 1-18/19-36 18 1 48.65%

Example. A corner covers 4 numbers, so it pays 36 ÷ 4 − 1 = 8 (8 to 1). Bet 10 and a win gives you 80 (and your 10 back).

Exception: the five-number bet on 0, 00, 1, 2 and 3 that exists only at double-zero tables (first five, TOP LINE on the table) pays 6 to 1 and has a 7.89% house edge, more than the 5.26% of the other bets.

What happens when zero comes up differs by table (Zeros and zero rules). Betting systems (such as doubling after a loss) cannot overcome the zero.

Zeros and zero rules

  • La partage: when zero comes up, even-money bets such as red or black get half the stake back.
  • En prison: when zero comes up, even-money bets such as red or black go in prison. If the next spin wins, the stake comes back; if it loses or zero comes up again, it is lost.

The number of zeros on the wheel, and what happens to even-money bets (red, black and so on) when zero comes up, differ by table. The two right-hand columns are house edges.

Table Pockets Even-money bets Other bets
Single 0 37 2.70% 2.70%
Double 0 38 5.26% 5.26%
Triple 0 39 7.69% 7.69%
La partage 37 1.35% 2.70%
En prison 37 1.39% 2.70%

At Single 0, Double 0 and Triple 0 tables, even-money bets lose when zero comes up. The en prison rule is explained below.

Triple 0

With three zeros every bet costs the most (3/39 = 7.69%). A bet on the three zeros 0, 00, 000 (Green) pays 11 to 1.

Example. A bet of 10 on a straight loses 0.27 per spin on average at a Single 0 table, and 0.77 at a Triple 0 table. About three times as much.

Check the actual order on the casino’s wheel.

En prison

When zero comes up, even-money bets are not lost but go “in prison” (left on the table with a marker). If the bet wins on the next spin, the stake comes back (no payout); if it loses, it is lost. A second zero on that spin also loses it.

Example. 10 on red, and zero comes up: the bet goes in prison. If red comes next, the 10 comes back. If black or zero comes, the 10 is lost.

A bet in prison is worth 18/37 of the stake (the chance of winning the next spin), so the house edge is about 1.39%, a little more than la partage (1.35%). Some tables keep sending the bet back to prison on every further zero, which costs a little less (about 1.37%).

Call bets

Call bets cover a section of the wheel (an area) in one go. They are used at single-zero tables: you name the bet and the dealer lays out the chips in a fixed pattern.

Name Area Chips
Voisins du Zéro The 17 pockets around zero (22 to 25) 9
Tiers du Cylindre The 12 pockets opposite zero (27 to 33) 6
Orphelins The remaining 8 pockets 5
Jeu Zéro The 7 pockets right by zero (12 to 15) 4
Neighbours A number and two on each side 5

Placement.

  • Voisins du Zéro: 2 on 0-2-3, splits 4/7, 12/15, 18/21, 19/22, 32/35, and 2 on the 25-26-28-29 corner
  • Tiers du Cylindre: splits 5/8, 10/11, 13/16, 23/24, 27/30, 33/36
  • Orphelins: a straight on 1 and splits 6/9, 14/17, 17/20, 31/34
  • Jeu Zéro: splits 0/3, 12/15, 32/35 and a straight on 26
  • Neighbours: 5 straights

They are all combinations of standard bets (straights, splits, corners and so on), so the house edge is the single-zero 2.70%. It stays the same at la partage and en prison tables, because no even-money bet is involved.

Example. Six chips of 1 on Tiers. If 27 comes up, the 27/30 split pays 17 to 1 for +17, the other five chips are lost, and the total is +12.

Betting an area does not make winning any more likely.
