La Partage is a roulette rule that returns half of an eligible even-money stake when the ball lands on the single zero. The other half is lost. It normally applies only to red/black, odd/even, and 1–18/19–36 wagers on a French or selected European roulette game.
Plain Talk
“La Partage” means “the sharing.” When zero lands, the eligible stake is split between the player and the house.
Suppose you bet $40 on red:
- Red lands: you win $40 profit.
- Black lands: you lose $40.
- Zero lands under standard European rules: you lose $40.
- Zero lands with La Partage: you lose $20 and receive $20 back.
The rule does not change the wheel, the 1-to-1 payout, or the probability of red. It changes only the loss on zero for the listed even-money wagers.
| Bet type | Normal result when zero lands | La Partage result |
|---|---|---|
| Red or black | Full stake lost | Half lost, half returned |
| Odd or even | Full stake lost | Half lost, half returned |
| 1–18 or 19–36 | Full stake lost | Half lost, half returned |
| Dozen or column | Full stake lost | Normally no La Partage treatment |
| Straight-up or split | Full stake lost | Normally no La Partage treatment |
A current French Roulette rule page states that the player loses only half of an even-money bet when zero is the result. Nevada’s approved Roulette rules provide the standard single-zero wager and payout framework against which special rules should be compared.
Where You See It
La Partage is most strongly associated with French roulette. It also appears on selected European roulette tables and live-dealer games. The table layout, help screen, or posted rules should state whether it applies.
Do not assume that every single-zero wheel offers La Partage. Many European roulette games use the normal rule in which zero takes the entire even-money stake. The wheel can look identical while the settlement rule is different.
The rule is less common on American double-zero and triple-zero games. If a product advertises a similar refund on another wheel, read the exact conditions rather than assuming traditional French settlement.
Why It Matters
On a standard single-zero wheel, an even-money bet wins on 18 pockets and loses on 19 pockets because zero is outside red/black, odd/even, and high/low. The full zero loss creates a house edge of 1/37, or about 2.70%.
La Partage turns the zero result into a half loss. The win and ordinary loss probabilities cancel, leaving only half of one unit lost over 37 equally likely pockets. The house edge becomes about 1.35% on qualifying bets.
This is a genuine rules improvement. It is not a betting system and it does not predict spins.
Formula and Expected Cost
For a one-unit even-money wager on a single-zero wheel:
Standard settlement:
EV = (18/37 × +1) + (19/37 × -1) = -1/37
House edge ≈ 2.7027%
La Partage settlement:
EV = (18/37 × +1) + (18/37 × -1) + (1/37 × -0.5)
EV = -0.5/37 ≈ -1.3514%
| Total even-money action | Standard expected loss | La Partage expected loss |
|---|---|---|
| $500 | About $13.51 | About $6.76 |
| $2,000 | About $54.05 | About $27.03 |
| $10,000 | About $270.27 | About $135.14 |
Actual session results can be far above or below those averages.
Example
You place $60 on odd at a table offering La Partage.
The ball lands on 0. The dealer divides the wager:
- $30 is collected by the house.
- $30 is returned to you.
If the next spin is odd, that does not recover the previous $30 automatically. Each completed spin is settled under the posted rules.
Now suppose you placed $60 on the first dozen instead. Zero normally loses the full $60 because dozens are 2-to-1 wagers, not even-money wagers.
La Partage Versus En Prison
Both rules soften the zero result on eligible even-money bets, but the procedure differs.
| Rule | What happens on zero | When the result is final |
|---|---|---|
| La Partage | Half is returned and half is lost | Immediately |
| En Prison | The stake is held for another spin | After the later qualifying result |
Under common single-zero versions, both rules produce an effective house edge of about 1.35% on the eligible wagers. En Prison can involve more procedural detail because the original chips remain marked or restricted until the next outcome.
Read En Prison for the separate rule.
From the Casino Side
La Partage is straightforward mathematically but requires precise table procedure.
Dealers and supervisors need to confirm:
- the table actually offers the rule;
- the wager is an eligible even-money bet;
- zero is the winning number;
- the stake can be divided into valid chip amounts;
- any odd chip or non-divisible amount is handled under house procedure;
- the half return is not confused with a win.
Clear signage matters because a player moving between roulette tables may expect the same zero settlement everywhere. The dealer should announce zero and apply the rule consistently before clearing or returning wagers.
Electronic games should show the half-loss transaction clearly in the credit meter and game history. A player should be able to distinguish the amount returned from a prize.
Common Misunderstandings
“La Partage applies to every outside bet.” Usually no. Columns and dozens are outside bets, but they are not even-money bets.
“Half my bet back means I broke even.” No. Half was returned and half was lost.
“French wording means the wheel has better numbers.” No. The standard French wheel still has 37 pockets. The improvement comes from settlement.
“A Martingale becomes safe with La Partage.” No. The rule lowers expected cost but does not remove table limits, bankroll risk, or losing sequences.
“Every European roulette game uses it.” No. Availability is product- and table-specific.
Hard Truth
La Partage is one of the few roulette conditions that cuts the mathematical price of a wager. It still leaves a negative expectation and cannot turn progression betting into an advantage.

FAQ
Does La Partage apply when double zero lands?
Traditional La Partage is associated with a single-zero French or European game. A double-zero product would need its own explicit rule.
Can I choose La Partage after zero lands?
Normally the table rule applies automatically. It is not a decision made after the outcome.
What happens to an odd chip that cannot be divided exactly?
House procedure controls. The minimum chip denomination and published rule should prevent or explain an indivisible settlement.
Is La Partage better than standard European roulette?
For eligible even-money wagers, yes. It halves the long-run house edge from about 2.70% to about 1.35%.
Does it improve straight-up bets?
No. A straight-up number normally loses in full when another number, including zero, wins.
Deeper Insight
La Partage shows why game selection matters more than betting pattern. A player can use the same $10 red wager on two visually similar single-zero tables and face different expected costs solely because one table returns half on zero.
The relevant comparison is:
Expected loss = total eligible action × applicable house edge
A slower game with La Partage can reduce expected hourly cost twice: through the lower edge and through fewer completed wagers. Neither factor guarantees a winning session.
