The Wheel Is the First Difference You Notice
You sit down at a roulette table and the first thing that tells you which game you are playing is the wheel itself. An American wheel carries 38 pockets: the numbers 1 through 36, a single zero, and a double zero. A French wheel carries 37 pockets: the same numbers 1 through 36 and only a single zero. That one extra pocket is not a cosmetic detail. It changes the arithmetic of every bet on the layout, and it is the reason the two games feel different over a session even when the betting options look nearly identical.
The second difference is quieter. French roulette, as played under traditional French rules, attaches special conditions to even-money bets when the ball lands in zero. American roulette does not. Those conditions, called la partage and en prison, do not change what you are betting on. They change what happens to your stake after a losing spin, and that is where the real strategic difference between the two games lives.
Layout, Language and the Sequence of a Round
Both games use the same basic table: a felt layout with a grid of numbers and a set of outside betting areas for red or black, odd or even, high or low, dozens and columns. On a French table the layout is traditionally printed in French, so you will see Impair and Pair for odd and even, Manque and Passe for low and high, and Rouge and Noir for red and black. The American layout uses English throughout. The betting options themselves are the same categories; only the labels differ.
A round moves through the same stages in either game. You buy chips at the table, place bets before the croupier calls no more bets, watch the ball spin and settle, and then see losing bets cleared and winning bets paid. The croupier controls the pace. In French roulette the croupier traditionally uses a rake to clear and pay bets; in American roulette the dealer usually works by hand. That is a procedure difference, not a rule difference, but it changes the rhythm of the game.
The decision points are identical. You choose a number, a group of numbers, or an outside category, and you choose how much to stake. What differs is what the house keeps on average from each wager, and what protection a zero spin gives to your even-money money.
How the Extra Pocket Changes the House Edge
House edge is the mathematical advantage the operator holds on a given game, expressed as a percentage of each wager. House edge and RTP are complements: they sum to 100% for the same game under the same rule set. On a single-zero wheel, every bet loses at a slower expected rate than the same bet on a double-zero wheel, because the double zero adds one more losing pocket without adding any new winning combinations.
The exact percentage depends on the bet. The relationship, though, is constant: for the same bet under the same rule set, the American layout carries a higher house edge than the French layout. The difference is not a matter of opinion or table style. It is built into the wheel. A straight-up bet on a single number pays the same odds on both wheels, but on the American wheel that number has one extra competitor, the double zero, which never helps a number bet.
This does not mean a French wheel is generous and an American wheel is stingy. Both are negative-expectation games. The operator holds an edge on every spin in both formats. The French wheel simply holds a smaller edge, which means the expected rate of loss is lower for the same stake and the same betting pattern.
La Partage and En Prison: The French Even-Money Rules
The most misunderstood part of French roulette is what happens when you have an even-money bet on the layout and the ball lands in zero. On an American wheel, that even-money bet loses outright. On a French wheel under traditional rules, one of two things happens instead.
Under la partage, the house returns half your even-money stake immediately. You lose the other half. Under en prison, your full stake is held on the table, in prison, and carried to the next spin. If that next spin wins, you get the stake back without any winnings; if it loses, the house takes the whole stake. Some tables apply one rule, some the other, and some apply neither, so the only reliable way to know is to read the table rules posted at the specific venue or shown in the game information panel online.
Both rules reduce the house edge on even-money bets specifically, because they soften the loss on the zero. They do not change the edge on inside bets or on dozens and columns. A straight-up number bet on a French wheel does not get la partage protection. Only the even-money outside bets qualify, and only when the table runs the rule.
| Feature | French roulette | American roulette |
|---|---|---|
| Wheel pockets | 37 (single zero) | 38 (single and double zero) |
| Layout language | Traditionally French labels | English labels |
| Even-money bet on zero | La partage or en prison may apply | Loses outright |
| House edge on same bet | Lower for every bet type | Higher for every bet type |
| Betting options | Same categories, French names | Same categories, English names |
Bet Types and Where the Edge Sits
Both wheels offer the same families of bets. Inside bets sit on the number grid: straight-up on one number, split on two, street on three, corner on four, six-line on six. Outside bets sit around the grid: red or black, odd or even, high or low, dozens and columns. The payout odds are printed on the layout and are the same on both wheels for the same bet type.
What differs is the edge attached to each bet, and that edge is always higher on the American wheel because of the double zero. The difference is most visible on even-money bets, where the French rules can cut the edge further. On inside bets, the French wheel still holds a lower edge than the American wheel, but la partage and en prison do not apply, so the protection is absent.
Some players assume the safest bet is the one with the biggest payout, or the one that covers the most numbers. Neither is true. The relevant comparison is the house edge on the specific bet under the specific rule set, and the table above shows how the two wheels rank. No bet on either wheel has a positive expectation for the player.
Strategy Charts, Rule Sets and What Transfers
Roulette does not have a basic-strategy chart in the way blackjack does, because there is no decision after the bet is placed. The only decisions are which bets to make, how much to stake, and when to stop. What transfers between the two games is the arithmetic: the same bet costs less in expected loss on a single-zero wheel than on a double-zero wheel, and an even-money bet costs less still if the table runs la partage or en prison.
No betting pattern changes the built-in edge. Doubling after a loss, covering the layout with many small bets, or alternating red and black does not remove the house advantage. Those patterns redistribute when wins and losses arrive; they do not change the long-run average. The only structural choice that changes the expected rate of loss is the wheel you sit at and the bets you place on it.
If you read a strategy chart for roulette, it is almost always a staking plan, not a decision chart. A staking plan tells you how to size bets across a session. It cannot tell you which number will hit, and it cannot turn a negative-expectation game into a positive one. Treat any chart that claims otherwise as a description of variance, not a method.
Procedural Mistakes New Players Make
The first mistake is betting after the croupier has called no more bets. Once the call is made, the layout is closed, and a late hand over the felt will get pulled back. The second is placing an even-money bet on a French table without checking whether la partage or en prison applies, then being surprised when a zero spin settles differently from what they expected. The third is assuming the payout odds differ between the two wheels. They do not; the payout for a straight-up bet is the same on both layouts. What differs is the edge, not the prize.
Another common error is mixing chips from another table. Roulette chips are often colour-coded per player at the table, and they have no cash value away from that specific wheel. If you carry them to a different game, you will be sent back. Cash out at the table before you leave.
Which Wheel You Should Sit At
If both games are available and the table minimums are the same, the French wheel is the structurally cheaper game to play, because every bet carries a lower house edge and even-money bets may carry the zero protection. That is a statement about expected loss, not about winning. A single session can go either way on either wheel. The French wheel simply charges less for the same action over the long run.
The American wheel is not a trap. It is the same game with one more pocket and a higher price. Many players prefer it because it is the version they learned first, or because it is the only one available where they play. If that is your situation, the same logic applies: the lowest-edge bets on an American wheel are still the even-money outside bets, and the highest-edge bet is the five-number basket on 0, 00, 1, 2 and 3, which exists only on the American layout and carries a worse edge than any other bet on the table.
Before you sit down, read the posted table rules. They state the minimum and maximum stake, whether la partage or en prison applies, and any special conditions on the wheel. Online, the same information sits in the game information panel or the help file for the specific title. The wheel type is always visible, so you can tell at a glance whether you are looking at a single-zero or double-zero layout.
FAQ
Is French roulette the same as European roulette?
They share the same single-zero wheel, but the names are not interchangeable. European roulette usually means the single-zero wheel without the French even-money rules. French roulette means the single-zero wheel with the traditional layout language and, at many tables, la partage or en prison on even-money bets. The wheel is the same; the table rules may differ.
Which bet has the lowest house edge in American roulette?
The even-money outside bets, such as red or black and odd or even, carry a lower edge than inside bets on the American wheel. The five-number basket covering 0, 00, 1, 2 and 3 carries the highest edge of any bet on that layout. The exact figures are printed in the game rules for the table you are playing.
Can la partage make roulette a winning game?
No. La partage reduces the house edge on even-money bets when the ball lands in zero, but the game remains negative-expectation. The rule lowers the expected rate of loss on those specific bets; it does not create a positive expectation, and it does not affect inside bets at all.
