La partage
A French roulette rule that gives back half of an even-money bet when the ball lands on zero, instead of losing the full stake.
Key points
- When zero appears, the casino keeps half the wager and returns the other half to the player.12
- The rule reduces the house edge on even-money bets from 2.70% to 1.35% on a single-zero wheel.1
- La partage differs from en prison, where the stake is held for the next spin rather than split immediately.12
