A zero can have a special settlement treatment on some roulette tables. The important question is the published rule for the particular wager, not whether the table looks French or uses French labels.
In its official roulette product overview, Evolution describes its French Roulette as single-zero and explains that La Partage returns half an even-money stake when zero appears. This article analyses that stated rule. It does not assume every table called French Roulette has identical terms.
A one-unit model
Assume a fair 37-pocket wheel, an even-money selection covering 18 pockets, and exactly the half-loss treatment described above. A one-unit stake produces a net gain of one unit on 18 outcomes, a loss of one unit on another 18, and a loss of half a unit on zero.
The expected net result is therefore (18 × 1 − 18 × 1 − 0.5)/37 = −0.5/37, about −0.01351 units per unit staked. Expressed as a proportion, the expected loss is approximately 1.35%. This is our calculation under the stated assumptions, not a forecast for any session.
What the calculation does not say
The chance of the selected even-money outcome in this model remains 18/37. The settlement on one other outcome has changed; the wheel has not gained additional winning pockets. Half a stake returned also means half a stake lost, not a full refund or a profit.
An expected value averages possible results using probabilities. It does not promise that a person will lose exactly that percentage, and it does not limit the size of an actual loss. A small sample can differ sharply from the average.
Show the exception accurately
A casino influencer explaining the rule should identify the eligible wager, wheel type and zero settlement before using a percentage. Do not extend an even-money exception to straight-up numbers or other wagers without evidence in that game’s rules. For footage with an unclear game identity, describe the visible return without asserting a universal rule. The useful lesson is precise accounting, not an invitation to gamble.
