PanaloKO French Roulette: How La Partage and En Prison Work

French roulette is the single-zero wheel with a French-style layout and, at some tables, a rule that softens zero for even-money bets. The wheel has 37 pockets, one green, so the baseline house edge is 1/37, or 2.70 per cent. Before you sit at a table in the lobby’s Live game section, read its rules panel for the zero rule; the live casino rules hub covers the other tables you will see beside it.

French roulette layout in plain English

The even-money bets carry French names on a French layout. Each covers 18 of the 37 pockets and none covers zero.

Payouts match the standard single-zero table in Pragmatic Play’s Live Roulette help: 35 to 1 straight up, 2 to 1 on dozens and columns, 1 to 1 on even chances. The same text gives the single-zero game a theoretical return of 97.30 per cent. Everything below is worked out from that wheel, so you can check each figure with a calculator.

La partage: half the stake back on zero

La partage applies only to even-money bets. When the ball lands on zero, the house keeps half your stake and returns the other half. Here is a one-peso stake on red, worked out chance by chance:

Add it up: (18 x 2 + 1 x 0.5) / 37 = 36.5 / 37 = 0.9865, a 98.65 per cent return and a 1.35 per cent edge. That is half the edge of the plain single-zero wheel at 2.70 per cent. On a ₱100 stake, a zero hands back ₱50. Over 100 spins of ₱100 on red, the average cost falls from about ₱270 to about ₱135, and in the long run zero only comes up once in 37 spins, so the saving is felt as a slower drain rather than a visible win.

Roulette en prison: the stake waits one spin

The en prison rule also protects only even-money bets. When zero lands, your stake is held, or imprisoned, for the next spin. If your bet wins that spin the stake is released with no profit, and if it loses the stake is gone. Some tables apply the rule again on a second zero, so read the panel for the exact version.

On a ₱100 stake the outcomes after a zero are:

The maths lands in the same place. If a zero keeps imprisoning the stake until a decision, the held stake is worth V, where V = 18/37 + V/37. That gives V = 18/36, or 0.50, the same as la partage, so the return is again 98.65 per cent.

Which bets get the rule

Neither rule touches inside bets, dozens or columns. A straight-up number still loses its stake on zero and still costs 2.70 per cent. An American wheel has two green pockets, and any zero rule there is something to look for in the panel; the American roulette double zero page shows the 5.26 per cent that results.

If you like sector bets across the wheel, the roulette racetrack layout explains how those chips are placed. Those bets carry the full 2.70 per cent.

Check the zero rule before you stake

1. Open the rules or Bet Limits and Payouts window and search for la partage or en prison.
2. Confirm which even-money bets the rule covers.
3. If neither rule is listed, treat a zero as a full loss on every bet.
4. Set a stop point using the loss limit meaning before you place the first chip.
