What changes between roulette types
The first thing to understand is that most of the game is identical across every variant. A ball spins in a wheel, you place bets on where it will land, and the payout for a correct single-number bet is the same on every standard layout. What differs is the number of pockets on the wheel, a few table rules that can return part of a losing bet, and the betting layout itself. Those differences are enough to change the house edge on the same bet by a meaningful margin.
Roulette variants are not separate games. They are the same game with different equipment and, in one case, different settlement rules. The wheel type is the biggest divider, and the table rules sit on top of it.
The three main wheel and table types
When a casino floor or an online lobby lists roulette, it is almost always one of three configurations: European, American, or French. European and French share the same 37-pocket wheel with a single zero. American adds a second zero pocket and carries a higher house edge on nearly every bet as a result.
| Feature | European | American | French |
|---|---|---|---|
| Pockets | 37 (0-36) | 38 (0, 00, 1-36) | 37 (0-36) |
| Zero pockets | Single zero | Single and double zero | Single zero |
| House edge on even-money bets | Higher than French | Highest of the three | Lower, when special rules apply |
| Layout language | Usually English | English | French labels on the table |
| Special rules | None standard | None standard | La partage or en prison on some tables |
The extra pocket on an American wheel is the single most important fact in this comparison. A European wheel has 37 pockets; an American wheel has 38. That one added pocket increases the house edge on the American layout, because the payout for a winning number does not grow to match the lower probability of hitting it.
What French rules do
French roulette is not defined only by the wheel. It is defined by what happens after the ball lands in zero when you have placed an even-money bet such as red or black, odd or even, or high or low. On a standard European or American table, that bet loses outright. On a French table with the right rules, one of two things happens instead.
Under la partage, the operator returns half of the even-money wager immediately. Under en prison, the full wager is held on the table for the next spin. If the next spin wins, the wager is returned without profit; if it loses, the wager is collected. Both rules reduce the expected loss on even-money bets specifically. They do not change the edge on inside bets.
Not every table labelled French offers these rules. The table's felt, the game information panel, or the help text in an online game states which rule applies, if any. A French-language layout without la partage or en prison is just a European wheel with different labels.
How the betting layout divides the game
Every roulette table separates bets into inside and outside categories. Inside bets sit on the numbered grid and pay more because they win less often. Outside bets sit around the grid, cover larger groups of numbers, and pay closer to even money. The distinction matters because the house edge is not identical across every bet on the same table.
| Bet type | What it covers | Payout | Edge behaviour |
|---|---|---|---|
| Straight up | One number | Highest fixed payout | Same house edge as most inside bets |
| Split | Two adjacent numbers | Half of straight-up payout | Same house edge as most inside bets |
| Street | Three numbers in a row | Lower than split | Same house edge as most inside bets |
| Corner | Four numbers in a block | Lower than street | Same house edge as most inside bets |
| Six line | Six numbers in two rows | Lower than corner | Same house edge as most inside bets |
| Even-money outside | Red/black, odd/even, high/low | 1:1 | Lower edge; reduced further by French rules |
| Dozens and columns | Twelve numbers | 2:1 | Higher edge than even-money outside bets |
On a standard wheel without French rules, the house edge on most inside bets and on the dozens and columns is the same, while the even-money outside bets carry a lower edge. The American wheel raises the edge across the board. The five-number bet found only on American layouts, covering 0, 00, 1, 2 and 3, carries a higher edge than any other bet on that table, because its payout does not match the true odds of the five pockets it covers.
The sequence of a round
A round moves through a fixed sequence whether you are at a physical table or an online one. First you buy in or load a balance. At a live table you place cash on the felt and receive colour chips that belong only to you at that table; online, you select a chip value from the cashier display. Then the betting window opens, you place wagers, and the dealer or software closes the window with a call of no more bets.
The ball is released in the opposite direction to the spinning wheel. When it drops into a pocket, the dealer places a marker on the winning number, clears all losing bets first, and then pays winners. Online, the software performs the same steps instantly and shows the result in the round history. Your balance updates only after losing bets are collected and winning bets are paid.
At a physical table, you must exchange colour chips back for cash-value chips before leaving, because colour chips have no value at the cashier cage. Online, the balance is just the balance.
Where the house edge comes from
Roulette does not hide its edge in complex strategy. The edge is built into the mismatch between the payout and the true odds of a bet. A straight-up bet on a European wheel pays 35 to 1, but the true odds against any single number are 36 to 1, because there are 36 other pockets. The operator keeps that difference over the very large number of spins that the return-to-player percentage describes.
That is why the wheel type matters more than any betting pattern. No sequence of bets changes the number of pockets on the wheel. A player choosing between variants is choosing between different expected rates of loss on the same wagers, not between different games.
What new players get wrong at the table
The most common procedural mistake is placing a bet after the dealer has called no more bets. Late bets are returned or, at a busy table, simply not booked, and the player can miss the spin while arguing about it. The betting window is short, so place outside bets first and inside bets after.
The second mistake is treating colour chips as cash. A player who walks away from the table with colour chips has left value behind, because those chips must be converted before they mean anything at the cage. The third is not checking the table minimum before buying in, which leads to a stack of chips that cannot cover the bets the player intended to make.
A fourth mistake is more conceptual: assuming the French label means the better rules. It does not, unless the table explicitly states la partage or en prison. The label alone changes nothing about the edge.
FAQ
Which type of roulette has the lowest house edge?
A single-zero wheel with la partage or en prison on even-money bets has the lowest expected loss among standard variants. A single-zero wheel without those rules still carries a lower edge than a double-zero American wheel, but the French rules reduce the edge further on the bets they cover.
Can I play French rules online?
Some online tables are labelled French and implement la partage or en prison, while others only use the French layout language. The game information panel or help file states which rule applies. If the rule is not named, the table settles a zero on even-money bets as a loss like any other European table.
Does the type of roulette change how I should bet?
The mechanics of each bet are the same across variants. What changes is the expected rate of loss on every wager, because the wheel has a different number of pockets. A bet that covers the same numbers costs more in expectation on an American wheel than on a European one, so the variant choice is itself the biggest decision before any bet is placed.
