Voisins du Zéro—French for “neighbors of zero”—is a traditional roulette call bet covering the large wheel sector around the single zero. It is associated with European/French roulette and is commonly selected from a racetrack layout or announced to the dealer where call bets are accepted.
The standard nine-unit Voisins package covers 17 numbers. It is not one exotic wager with one special payout. It is a bundle of ordinary inside bets placed together on a specific sector of the wheel.
The standard nine-unit placement
A common traditional Voisins du Zéro placement uses nine units like this:
| Placement | Units | Numbers covered |
|---|---|---|
| 0-2-3 trio | 2 | 0, 2, 3 |
| 4/7 split | 1 | 4, 7 |
| 12/15 split | 1 | 12, 15 |
| 18/21 split | 1 | 18, 21 |
| 19/22 split | 1 | 19, 22 |
| 25/26/28/29 corner | 2 | 25, 26, 28, 29 |
| 32/35 split | 1 | 32, 35 |
Total stake: 9 units.
Unique numbers covered: 17 of the 37 pockets on a single-zero wheel.
The double units on the 0-2-3 trio and the 25-26-28-29 corner are not decoration. They are what make the traditional package’s returns line up in a particular way across different winning areas.
Why this is a wheel-sector bet, not a layout-sector bet
Roulette numbers are arranged one way on the betting layout and a completely different way around the physical wheel.
Voisins du Zéro follows wheel adjacency. The covered numbers occupy the broad arc surrounding zero on the European wheel. That is why the package can look scattered when the dealer places it on the rectangular inside-bet grid.
This is also why the racetrack bet interface is so useful. The racetrack redraws the numbers in wheel order, allowing players to select sectors without memorizing every split and corner on the main layout.
A neighbor bet uses the same wheel-order idea on a smaller scale around one selected number. Voisins is a named, much larger traditional sector.
What happens when a covered number wins
Each chip in the package is settled according to the ordinary inside bet it represents.
On a standard single-zero table:
- a split pays 17 to 1;
- a trio pays 11 to 1;
- a corner pays 8 to 1.
Because the package contains nine units, the net result depends on which part hits.
If 0, 2, or 3 wins
Two units are on the trio. Each winning trio unit earns 11 units of profit, so the winning portion produces 22 units of profit. The other seven units lose.
Net result: +15 units.
If a split-covered number wins
One unit on the winning split earns 17 units of profit. The other eight units lose.
Net result: +9 units.
If 25, 26, 28, or 29 wins
Two units sit on the four-number corner. Each wins 8 units of profit, for 16 units total profit. The other seven units lose.
Net result: +9 units.
So the traditional package creates one higher-return section around the zero trio and a common +9-unit net result across the other covered numbers.
The nine-chip package still has ordinary single-zero roulette mathematics
Voisins can feel safer because 17 numbers are covered, but the player is also staking nine units per spin.
Using the standard placement above:
- 3 numbers produce +15 units net;
- 14 other covered numbers produce +9 units net;
- 20 uncovered numbers produce -9 units.
The expected value per nine-unit package is therefore:
EV = [3(15) + 14(9) + 20(-9)] / 37
EV = -9 / 37 ≈ -0.24324 unit
Relative to the nine units staked:
House edge = (9/37) / 9 = 1/37 ≈ 2.70%
So a standard Voisins package built entirely from ordinary European inside bets has the same basic 2.70% house edge as those component bets.
Coverage changed. Total stake changed. The underlying price did not become favorable.
“One unit on Voisins” usually means nine units of actual action
This is one of the most important practical details.
If a player says “Voisins for $5” in a setting where the phrase means a $5 unit, the total stake is normally:
9 × $5 = $45
A $25 unit means:
9 × $25 = $225
That is why players should confirm how the table quotes call-bet units. A named sector can sound like a single $5 or $25 wager even though the dealer is placing multiple chips.
The larger total action also affects session cost. At $5 per unit, 30 Voisins spins represent $1,350 of total wagers. At a 2.70% single-zero edge, the mathematical expected loss on that action is about $36.49, though actual results can be far above or below that figure.
The French name is traditional, but availability is local
Voisins du Zéro is a recognized classical roulette announcement. French casino regulation has historically named voisins du zéro, orphelins, tiers, and number finales among the classic roulette announcements; the French legal text is available through Légifrance.
That recognition does not mean every roulette table worldwide must accept the call in the same form.
Availability can depend on:
- whether the game is single-zero or double-zero;
- whether the table accepts announced bets;
- whether the property uses a racetrack layout;
- the minimum chip value for call bets;
- local gaming rules;
- whether the game is live, stadium, or electronic roulette.
On an electronic terminal, the software may display the exact total stake before acceptance. On a live table, the dealer may repeat the call and amount before placing the chips.
Voisins, Tiers, and Orphelins divide the wheel by geography
The three famous French sector names are easier to remember if you think in wheel geography:
- Voisins du Zéro covers the broad zero-side sector.
- Tiers du Cylindre covers roughly the opposite third of the wheel.
- Orphelins covers the “orphan” numbers left outside the two larger sectors.
They are not betting systems and they do not claim that one sector is due. They are shorthand for placing several inside bets efficiently.
Compare Tiers du Cylindre and Orphelins for the other named sections.
A wheel-section bet does not become predictive because recent spins clustered nearby
If several recent results landed around zero, a player may feel that the sector is “active.” Another player may reach the opposite conclusion and decide the zero side has already appeared too often.
Neither story changes the physical payout mathematics of a fair wheel.
Voisins is a coverage choice, not a forecast. It changes which 17 numbers have money on them and how much total stake is exposed. It does not make those pockets more likely because they appeared recently.
If a casino suspects a genuine mechanical bias, wheel defect, ball defect, or other integrity problem, that is an operating and regulatory matter—not the same thing as reading streaks on a public results board.
What the dealer has to get right
From the casino side, the difficulty is procedural rather than mathematical. A nine-unit call has to be placed quickly and accurately across several distant areas of the layout.
The dealer needs to know:
- the property’s accepted Voisins placement;
- the player’s unit size;
- whether the announcement arrived before betting closed;
- how the chips are identified if several players make call bets;
- how the winning piece is paid without overlooking losing components;
- whether the table uses lamers, racetrack indicators, or other local controls.
That is why announced bets are repeated back clearly in disciplined pits. A dispute after the ball lands is much harder to resolve than an amount clarified before no more bets.
The definition to remember
Voisins du Zéro is a named European roulette wheel-sector package, traditionally nine units covering 17 numbers around zero. The component chips are ordinary inside bets; the name is a convenient way to place them as a group.
The package increases coverage and total stake, not predictive power.
