French Roulette Guide: La Partage, En Prison and Even-Money Bet Rules
French roulette usually uses a single-zero wheel and may include La Partage or En Prison rules. These rules can reduce the house edge on qualifying even-money bets to 1.35%, but they do not make roulette profitable or predictable.

Quick answer
French roulette is usually a single-zero roulette variant with special rules that may apply to even-money bets. La Partage returns half the stake when zero lands. En Prison holds the even-money bet for the next spin. When available, these rules can reduce the even-money house edge to 1.35%.
French roulette answer box
French roulette is strongest as a rules comparison page when it explains exactly where La Partage and En Prison matter: usually even-money bets only, only when the table displays the rule, and never as a way to make roulette predictable.
What French roulette is
French roulette normally uses the same 37-pocket wheel as European roulette: 0 and 1-36. The difference is the table language and, on some tables, zero rules that soften losses on even-money bets. The rules do not make roulette predictable or profitable.
La Partage vs En Prison
| Rule | What happens when zero lands | Usually applies to | House-edge caveat |
|---|---|---|---|
| La Partage | Half of the even-money stake is returned. | Red/black, odd/even, high/low. | Can reduce even-money house edge to 1.35%. |
| En Prison | The even-money stake is held for the next spin. | Red/black, odd/even, high/low. | Settlement and availability vary by table. |
| No special zero rule | The even-money bet loses when zero lands. | All standard bets unless table rules say otherwise. | Standard single-zero house edge is 2.70%. |

Which bets the French rules apply to
La Partage and En Prison normally apply only to even-money bets: red or black, odd or even, and high or low. They generally do not apply to straight-up bets, splits, streets, corners, dozens or columns. Always confirm the exact table rules before playing.
House edge comparison
| Variant or rule | Wheel | Bet scope | Typical house edge | Important caveat |
|---|---|---|---|---|
| French roulette with La Partage | Usually single zero | Even-money bets only | 1.35% | Only when the rule is active on the table. |
| French roulette with En Prison | Usually single zero | Even-money bets only | Can be equivalent to 1.35% | Settlement can vary, so read table rules. |
| European roulette | Single zero | Standard bets | 2.70% | Still negative expected value. |
| American roulette | Double zero | Most standard bets | 5.26% | The extra 00 raises long-run cost. |
French table terminology
French roulette tables may label outside bets in French. Manque usually means low numbers 1-18, Passe means high numbers 19-36, Pair means even, and Impair means odd. Terminology helps you read the table; it does not change the odds.
Betting systems still do not change the odds
Martingale, Fibonacci and other progressive systems can organize stake sizes, but they do not change roulette probabilities. Even with La Partage or En Prison, progressive systems can increase exposure, collide with table limits and create pressure to chase losses.
What to verify before playing French roulette
- Check that the table is actually labeled French roulette.
- Confirm whether La Partage, En Prison, both or neither rule is active.
- Confirm which bets the rule applies to.
- Check table limits and whether bonuses exclude roulette or count it at a reduced rate.
- Check legal availability and responsible gambling tools.
Common French roulette questions
Is French roulette better than European roulette?
French roulette can have a lower house edge on even-money bets when La Partage or En Prison applies. It is still a negative expected value gambling game.
Does La Partage apply to every bet?
No. It usually applies only to even-money bets, not inside bets, dozens or columns.
Do systems work with French roulette?
Systems do not change the odds. They can increase exposure and should not be used to chase losses.
