Play Roulette Using the La Partage Rule
This guide explains how the La Partage rule works on a single-zero roulette table, which bets it covers and what it does to the house edge. It is written for players in Ireland who already know red from black but want to understand why a French table can cost them less over time. We set out the rule, compare it with standard European roulette, walk through finding and using it online, and correct a few common myths about what the rule can and cannot do for a session.

What the La Partage Rule Actually Does
La Partage, French for “the sharing”, is a rule used on single-zero roulette tables, usually sold as French roulette. When the ball lands on zero, any even-money bet loses only half its stake, and the other half goes back to the player.
Even-money bets are the outside bets that pay one to one: red or black, odd or even, and low (1-18) or high (19-36). A €10 bet on red that meets a zero costs €5 rather than €10, and the round is over for that chip.
The effect on the house edge is exact, and it is worth working through once. A single-zero wheel has 37 pockets, so on a normal table the zero takes the whole even-money stake about once in every 37 spins, which gives the casino an edge of 2.70%. La Partage halves that loss on zero, so the edge on those bets falls to 1.35%, or one in 74. Over €500 of even-money stakes, that is a long-run average cost of about €6.75 instead of €13.50 — an average across many spins, never a forecast for one evening.
The rule changes nothing else.
Straight-up numbers, splits, dozens and columns keep the standard 2.70% edge, because La Partage does not apply to them. A table labelled “European” does not guarantee the rule either, so the game’s help panel is where a player confirms it.
La Partage Against Standard European Roulette
Both games use the same 37-pocket wheel; the difference sits entirely in how even-money bets settle on zero. The figures below come from the published mathematics of the single-zero wheel.
French table with La Partage | Standard European table |
|---|---|
| Half of an even-money stake returned on zero | Whole even-money stake lost on zero |
| 1.35% house edge on even-money bets | 2.70% house edge on even-money bets |
| 2.70% on inside bets, dozens and columns | 2.70% on inside bets, dozens and columns |
| 98.65% theoretical return on even-money bets | 97.30% theoretical return on even-money bets |
| Same 35 to 1 payout on a single number | Same 35 to 1 payout on a single number |
| Fewer tables carry the rule online | Found in nearly every game lobby |
How to Find and Use a La Partage Table
Finding the rule takes a minute of reading rather than any skill at the table. Online lobbies group roulette games by studio, and French roulette usually sits beside European and American versions under similar artwork.
The name on the tile is not enough. Some games called French roulette use En Prison instead, which holds the stake for one more spin rather than splitting it, and a few apply neither rule. The game’s rules or help screen states which applies, and that text is what decides the house edge, not the title.
Once the rule is confirmed, using it is passive: the software or the croupier returns the half-stake automatically when zero lands.
The player’s only real decision is where to put the chips. Because the rule protects even-money bets alone, a player who wants the 1.35% edge has to keep stakes on red or black, odd or even, or low or high. Spreading chips across numbers puts most of the money back at 2.70%.
Four Steps to a La Partage Spin
The procedure below applies to RNG and live French roulette tables alike, since the rule works the same way in both.
- Step 1
Open the French roulette section
In the casino lobby, search for French roulette rather than browsing the general roulette list. Single-zero tables are the only ones where La Partage is offered, so American double-zero games can be skipped entirely. - Step 2
Read the game's rules panel
Open the help or info screen and look for the words La Partage. If the panel names En Prison or no zero rule at all, the even-money edge differs from the 1.35% figure. - Step 3
Place an even-money outside bet
Put your chips on red, black, odd, even, 1-18 or 19-36. These are the only bets the rule covers; inside bets, dozens and columns stay at the normal 2.70% house edge. - Step 4
Check the settlement after zero
When zero lands, confirm that half of each even-money stake was returned to your balance. The game history or bet log normally shows this, which is useful if a result looks wrong.
Myths and Limits of the Half-Back Rule
La Partage lowers the price of playing even-money bets; it does not make roulette beatable. The casino keeps a 1.35% edge on every one of those bets, and no staking pattern changes that average.
Betting systems are the common confusion here. Doubling after a loss, as the Martingale does, alters how wins and losses cluster in a session, yet each spin still carries the same edge, so the long-run cost per euro staked stays at 1.35%. Table maximums and a finite bankroll mean a long losing run ends the progression anyway.
Zero is not “due” either.
Every spin of a fair wheel is independent, so a zero that has not appeared for a hundred spins is no more likely on the next one. The rule simply softens the damage when it does arrive, and the 1.35% figure only appears over thousands of spins. A single session proves nothing about the rule, good or bad, because short-run results swing far wider than the edge itself.
Players in Ireland can also use deposit limits and time-outs, which most operators offer in account settings, to keep play inside a budget set in advance.

La Partage Roulette: Common Questions
What does La Partage mean in roulette?
It means “the sharing” in French. When zero lands, even-money bets lose half their stake and the other half is returned to the player.
Which bets does La Partage cover?
Only even-money outside bets: red or black, odd or even, and 1-18 or 19-36. Numbers, splits, dozens and columns are settled normally when zero lands.
What is the house edge with La Partage?
On even-money bets it is 1.35%, half the 2.70% of a standard single-zero table. All other bets on the same table keep the 2.70% edge.
Is La Partage the same as En Prison?
No. En Prison holds the whole stake for another spin instead of returning half at once. Its edge is 1.35% or about 1.39%, depending on how a second zero is handled.
Does every French roulette game use La Partage?
No. Some use En Prison and a few use neither rule. The game’s rules or help panel states which applies, and that text is what counts.
Can La Partage help a betting system win?
No. It lowers the average cost of even-money bets but leaves the casino with an edge on every spin. Systems such as the Martingale change session swings, not the long-run average.

What we check first is whether the help panel names La Partage explicitly. The wheel looks identical on both tables, so the only gain lies in that line of rules text. For a player who sticks to red or black, it halves the long-run cost; for a number player, it changes nothing.
