La partage is a rule that activates on even-money bets when zero is spun. Instead of the full stake being lost, the table returns exactly half to the player and retains the other half. No second spin is required. The player makes no decision. Payout of the half-return happens immediately as part of the zero resolution, and the round ends for that chip.
This split applies to red, black, odd, even, high, and low even-money bets. If zero appears on any of these sections, players receive 50% of their chip value back. A 1,000-satoshi chip on red when zero is spun returns 500 satoshis. Share availability at crypto.games/roulette/bitcoin depends on the table configuration in use.
How does La Partage reduce the house edge?
On a single zero wheel without any special rules, zero produces a full loss on all even-money bets. It appears once every 37 spins on average and contributes the entire 2.70 per cent house edge that applies to those bet types. La partage changes the cost of zero from a full loss to a half loss.
Zero still appears at the same frequency. Nothing about the wheel changes. What changes is how much the player forfeits when it does appear. Across many sessions, the expected loss on even-money bets is cut in half because the zero result now costs 50 per cent of the stake rather than 100 per cent.
- Without la partage: zero appears, full stake lost. Average cost per zero event equals the full bet amount.
- With la partage: zero appears, half stake returned. The average cost per zero event equals half the bet amount.
House edge drops from 2.70 per cent to 1.35 per cent on even-money bets under la partage. Bets on other sections of the table, including straight-up, split, street, corner, column, and dozen, are not affected. La partage applies exclusively to the six even-money sections.
La partage and en prison compare
- Resolution timing. La partage settles immediately on the zero spin. En prison holds the stake for a second spin before resolving.
- Return certainty. La partage guarantees 50 per cent back on zero. En prison produces either full return or full loss, depending on the following spin.
- La partage removes variance from zero outcomes. En prison adds a full-stakes resolution event to each zero occurrence.
- Long-run edge. Both rules reduce house edge on even-money bets from 2.70 per cent to approximately 1.35 per cent when calculated across large sample sizes.
Players who prefer predictable session behaviour benefit more from la partage because each zero result ends with a known 50 per cent partial return. Players who accept variance in exchange for the possibility of a full stake recovery may prefer en prison, where it is available.
La Partage comes from French roulette traditions, which most commonly appear on European or French layout tables. Providers do not always activate it, and it is generally listed in the rules section instead of the main layout. When the player confirms the rule is active before placing chips, they can avoid taking advantage of benefits that don’t apply to their specific table.
