The bet that covers the wheel's zero neighbourhood
When a player at a roulette table says "voisins", they are not naming a single number. They are buying a package of bets that covers the section of the wheel where the zero sits, plus the numbers clustered immediately around it. The full name is voisins du zéro, French for "neighbours of zero", and it exists as a standard wager in many European casinos because the layout of the wheel makes that section a natural grouping.
The bet is fixed. The numbers it covers do not change from table to table, and the way the stake is divided does not change either. What changes is only how much the player puts down, because the total stake is always split into a set of smaller bets in fixed proportions. Understanding that split is the whole skill of the bet.
What the bet contains
Voisins du zéro covers 17 numbers: the zero itself and the 16 numbers that sit closest to it on a European wheel. On the physical wheel, the sequence runs 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, 25. A player who places this bet wins when any of those 17 pockets comes up.
The stake is not placed as a single 17-number wager, because no such chip exists on the standard layout. Instead, the total amount is divided across a combination of smaller bets that together produce the coverage. The standard division is expressed in multiples of a base unit, and the same proportions apply whether the player is betting small or large.
The package contains three kinds of wager: a straight-up bet on a group of single numbers, split bets on pairs, and corner bets on squares of four. The single numbers receive a larger share of the total stake than the splits, and the splits receive a larger share than the corners. The result is that a win on any covered number pays a different amount depending on which of the three bet types that number belongs to.
How the stake is divided
Every voisins du zéro bet is built from nine smaller bets. The total stake is divided into a fixed number of units, and those units are distributed as follows: two units go on the zero as a straight-up bet, one unit goes on each of five split bets, and one unit goes on each of three corner bets. The player does not choose this division; it is part of the bet's definition.
The split bets cover the pairs that sit adjacent on the wheel: 4 and 7, 12 and 15, 18 and 21, 19 and 22, and 32 and 35. The corner bets cover the squares 25-26-28-29, 2-3-5-6, and 17-18-20-21. The straight-up bet covers only the zero.
Because the stake is divided this way, a player who announces "voisins" with a total stake of nine units is effectively placing one unit on each of the nine component bets. A larger total stake simply multiplies every component. The player does not need to place nine separate chips; at tables that offer announced bets, the dealer places them on the layout from the player's single instruction.
Announced bets versus table bets
Voisins du zéro belongs to a family of wagers called announced bets, or call bets. These are wagers that a player declares verbally rather than placing chip by chip. They exist because the numbers they cover are grouped by their position on the wheel, not by their position on the betting layout, and the layout does not offer a convenient single chip for that grouping.
Announced bets are not available at every table. They are common on European-style roulette, where the wheel has 37 pockets and a single zero, and they are typically handled by the dealer or croupier rather than the player. On tables that do not offer announced bets, a player who wants the same coverage must place each component bet manually, which is slower and easier to get wrong.
The distinction matters for two reasons. First, an announced bet is a verbal instruction, so the player should confirm the total stake before the ball is released. Second, the bet is settled as a package: the player wins or loses on the whole combination, and the payout depends on which component bet the winning number belongs to.
| Component | Numbers covered | Units of stake | What it is |
|---|---|---|---|
| Straight-up on zero | 0 | 2 | A single-number bet paying 35 to 1 |
| Split 4/7 | 4, 7 | 1 | A two-number bet paying 17 to 1 |
| Split 12/15 | 12, 15 | 1 | A two-number bet paying 17 to 1 |
| Split 18/21 | 18, 21 | 1 | A two-number bet paying 17 to 1 |
| Split 19/22 | 19, 22 | 1 | A two-number bet paying 17 to 1 |
| Split 32/35 | 32, 35 | 1 | A two-number bet paying 17 to 1 |
| Corner 25/26/28/29 | 25, 26, 28, 29 | 1 | A four-number bet paying 8 to 1 |
| Corner 2/3/5/6 | 2, 3, 5, 6 | 1 | A four-number bet paying 8 to 1 |
| Corner 17/18/20/21 | 17, 18, 20, 21 | 1 | A four-number bet paying 8 to 1 |
The table shows the standard nine-unit construction. If a player announces a total stake of 18 units, every component doubles; if the total is 45 units, every component is multiplied by five. The proportions stay fixed.
What a win pays on each number
The payout on a winning voisins du zéro bet depends on which number arrives, because the covered numbers sit in different component bets. The zero pays the most, because it carries two units on a straight-up bet. A win on the zero returns the straight-up payout at 35 to 1 on two units, plus the player's stake on that component, while the other eight components lose.
The five split pairs pay at 17 to 1 on one unit each. The three corner squares pay at 8 to 1 on one unit each. In every case, the other eight components of the package lose. The player should read the net result as the payout on the winning component minus the seven or eight units lost on the others.
This is the key difference between a package bet and a single wager. A single straight-up bet on one number either wins or loses in full. A voisins du zéro bet almost always has a losing component, even when the player wins, because only one component can hit on any spin. The net return on a winning spin is therefore smaller than the gross payout on the winning component.
Where the house edge sits
Voisins du zéro is not a different game and it does not carry a different house edge from the rest of the roulette table. It is simply a combination of standard bets, and each component bet carries the same edge as any other bet of its type on a European wheel. The package does not alter the mathematics of the wheel; it only groups a set of numbers for convenience.
On a European wheel, the single zero produces the same house edge on every bet that pays at the standard odds for its coverage, and the voisins package is built entirely from such bets. The player's expected loss over time is the same as if they had placed the same nine bets individually. The package changes the rhythm of play, not the underlying rate of loss.
An American wheel, with its extra double-zero pocket, changes the picture. The voisins du zéro grouping is defined around the European wheel's zero neighbourhood, and the American wheel's number sequence is different. A player who tries to reproduce the bet on an American layout is not playing the same package, and the extra pocket increases the house edge on every component. The bet belongs to European roulette, and that is where its standard form applies.
How a round plays out with this bet
A player who wants to place voisins du zéro buys in at the table, waits for the previous round to settle, and announces the bet with a total stake before the dealer calls for bets to close. At tables with announced bets, the dealer places the nine components on the layout. At tables without them, the player places each component manually, which is why the bet is far more common where announced bets are offered.
Once the ball is released, no further changes are allowed. When the ball lands, the dealer marks the winning number, clears the losing components, and pays the winning component at its standard odds. The player's net result is the payout on the winning component minus the stake on the eight losing components.
The bet is settled every spin. It does not roll over, and it does not carry any special status. A player who wants to keep the coverage must announce it again on the next spin with a fresh stake. The package is a convenience, not a contract.
Mistakes new players make with call bets
The first mistake is announcing a total stake without knowing how it divides. A player who says "voisins" and pushes forward a stack of chips may not realise that the total is being split nine ways, and that the payout on a winning number depends on which component that number belongs to. The remedy is to confirm the total and the division before the ball is released, and to ask the dealer to explain the component bets if anything is unclear.
The second mistake is assuming the bet covers half the wheel. It covers 17 numbers on a 37-pocket wheel, which is close to half but not exactly half, and the coverage is not evenly distributed. Some numbers carry a larger share of the stake than others, so the bet does not behave like a simple even-money wager. A player who expects a near-50% win rate with a flat payout will be surprised by the actual distribution of wins and losses.
The third mistake is carrying the bet to the wrong table. Voisins du zéro is a European-wheel bet, and it is not standard on American roulette. A player who asks for it on an American table may be told it is not offered, or may be offered a different grouping that does not match the European definition. The player should check the wheel type and the table's announced-bet policy before sitting down.
What the bet is and is not
Voisins du zéro is a fixed package of nine bets covering 17 numbers around the zero on a European wheel. It is a way to buy a specific section of the wheel in one instruction, and it is settled exactly like the individual bets that make it up. It does not change the house edge, it does not guarantee any outcome, and it does not make the zero section more likely to hit. It is a convenience for players who want that coverage without placing nine separate chips on every spin.
The bet is worth understanding because it appears often in European roulette, and because it teaches something about how roulette bets are built. Every wager on the layout is a claim on a set of numbers, and every claim pays according to how many numbers it covers. Voisins du zéro is simply a pre-packaged claim, and the player who understands its components understands the whole table a little better.
FAQ
Is voisins du zéro the same as tiers du cylindre?
No. Both are announced bets on a European wheel, but they cover different sections. Tiers du cylindre covers the 12 numbers opposite the zero on the wheel, while voisins du zéro covers the 17 numbers around the zero. They are separate packages with separate component bets.
Can I place voisins du zéro on an online roulette game?
Some online European roulette games include announced bets as a selectable option, often on a separate racetrack display that mirrors the wheel. Where the option exists, the software places the nine component bets automatically. Where it does not exist, the player must place each component manually on the standard layout.
Why does the zero pay more than the other numbers in the package?
Because the zero carries two units of the total stake on a straight-up bet, while the split and corner numbers carry one unit each. A straight-up bet also pays at higher odds than a split or a corner, so a win on the zero produces a larger gross payout than a win on any other covered number.
