The green pocket is a separate outcome, not a colour you can bet on
A roulette wheel carries either one green pocket or two. On a European layout the single zero sits in green; on an American layout a zero and a double zero both sit in green. The ball landing there is not a near-miss on red or black. It is its own result, and the table treats it as one.
That matters because most of the bets players make are not bets on a number. They are bets on a category: red or black, odd or even, high or low. When the ball lands in a green pocket, none of those categories has won. The zero is neither red nor black, neither odd nor even under the common table convention, and it sits outside the high and low ranges. Every one of those bets loses.
The reason the pocket exists is structural. The wheel needs a result that belongs to the house on the even-money propositions, because those propositions otherwise pay exactly what they take. Without a green pocket, a bet on red would pay 1:1 against a 50% chance, and the operator would hold no mathematical advantage on that wager. The zero creates the gap between the true odds of an event and the payout odds the table offers.
What settles as a win, and what settles as a loss
The moment the ball drops into a green pocket, the dealer announces the number and places the marker on the layout. Settlement then follows a fixed order: inside bets are paid first, then outside bets are collected. A bet placed directly on the zero, or on a combination that includes the zero, is an inside bet and can win. Everything else loses.
On a European wheel, a straight-up bet on zero pays 35:1, the same as any other single number. A split covering zero and one, or zero and two, or zero and three, pays 17:1. A street covering zero, one and two, or zero, two and three, pays 11:1. On an American wheel the double zero works the same way, and a five-number bet covering zero, double zero, one, two and three is available on many layouts; it carries a worse edge than any other bet on the table because it pays 6:1 against five winning pockets out of thirty-eight.
| Bet type | What it covers | What a green pocket does to it |
|---|---|---|
| Straight-up on zero | The zero pocket only | Wins, paid at 35:1 |
| Split including zero | Zero plus one adjacent number | Wins, paid at 17:1 |
| Street including zero | Zero plus two adjacent numbers | Wins, paid at 11:1 |
| Red or black | Eighteen pockets of one colour | Loses; zero is neither colour |
| Odd or even | Eighteen pockets of one parity | Loses; zero is treated as neither |
| High or low | Eighteen pockets in one range | Loses; zero is outside both ranges |
| Dozens or columns | Twelve numbers in a block or line | Loses unless the zero is included in the block |
Why the number of green pockets changes the edge
Every bet on a roulette table carries a house edge, and the size of that edge depends on how many pockets the wheel has and how many of them the bet covers. The presence of a second green pocket does not change the payout on any bet. It changes the probability that the bet wins, because the wheel now has one more losing pocket for every wager that does not include it.
A European wheel has 37 pockets and a single zero. An American wheel has 38 pockets and a double zero. The extra pocket increases the house edge on the American layout, as the reference material on roulette wheel types states. The comparison below shows how the two layouts differ for the main bet categories.
| Bet | Payout | Winning pockets, European (37) | Winning pockets, American (38) |
|---|---|---|---|
| Straight-up | 35:1 | 1 | 1 |
| Split | 17:1 | 2 | 2 |
| Street | 11:1 | 3 | 3 |
| Corner | 8:1 | 4 | 4 |
| Six line | 5:1 | 6 | 6 |
| Dozens or columns | 2:1 | 12 | 12 |
| Even-money bets | 1:1 | 18 | 18 |
The payout column is identical on both wheels. What differs is the denominator: the same number of winning pockets sits inside a wheel with one more losing pocket. The even-money bets show the effect most clearly. On a European wheel, eighteen winning pockets out of thirty-seven leaves nineteen losing pockets. On an American wheel, eighteen winning pockets out of thirty-eight leaves twenty losing pockets. The bet pays the same either way, so the American version loses more often for the same return.
Rules that soften the loss on a green pocket
Some European tables, and a smaller number of American ones, apply a rule that changes what happens to an even-money bet when the ball lands in a green pocket. The two common forms are la partage and en prison.
Under la partage, the player receives half the even-money stake back immediately. The other half is collected. Under en prison, the full stake is held in place, or imprisoned, for the next spin. If the next spin wins, the stake returns without profit; if it loses, the stake is collected. Both rules apply only to the even-money propositions, and only when the zero, not the double zero, is the pocket that landed. A table offering either rule reduces the cost of the green pocket on those specific bets, but it does not change the settlement of any inside bet or any dozen, column, or other outside bet.
The rule in force is printed on the table layout or posted on the placard beside the wheel. A player who wants to know which rule applies should read that placard before buying in, because the difference changes the expected cost of every even-money wager.
The sequence of a round, from buy-in to settlement
A roulette round runs through a fixed sequence, and most procedural mistakes happen because a player acts outside that sequence. The dealer closes betting before the ball slows, and any chip placed after the call is returned or pushed back. A player who does not know where their bet sits on the layout can misread a losing number as a winning one, because adjacent numbers on the wheel are not adjacent on the felt.
The buy-in happens at the table, not at the cashier. The player places currency on the felt, and the dealer exchanges it for roulette chips. These chips carry no denomination printed on them; their value is set by the player at the buy-in and marked by the dealer. They are valid only at that table, and they must be exchanged for regular casino chips before leaving. A player who walks away with roulette chips cannot cash them at the cage.
Once the chips are in hand, the player places them on the layout before the dealer calls no more bets. The dealer spins the wheel and releases the ball in the opposite direction. When the ball drops, the dealer marks the winning number, clears the losing bets, and pays the winners in order. The player then either leaves the chips in place for the next spin or collects them.
The three procedural mistakes that cost new players most often are betting after the call, misreading the layout, and treating roulette chips as cash chips at another table. Each is avoidable by watching one round before playing and by keeping roulette chips at the table until they are exchanged.
What the green pocket means for a session
The green pocket is the mechanism by which the even-money bets carry a house edge, and it is the reason a roulette session is a negative-expectation game. No betting pattern changes that. A player who doubles an even-money bet after a loss is placing a larger wager on the same probability; the green pocket is still there on the next spin, and the edge on that spin is unchanged. The zero does not become due, and a run of red numbers does not make a green pocket more likely.
What varies under the player's control is which bets they place and how long they play. A straight-up bet on a single number pays more when it wins and loses far more often. An even-money bet loses less often but pays only the stake back. The choice between them is a choice about how the session's variance will feel, not a choice that changes the long-run direction of the game.
Roulette is a game of independent spins. The wheel has no memory, and the green pocket has no schedule. The only certainty is that every spin carries the same probabilities, and that the green pocket, whenever it lands, settles the table exactly as the layout says it will.
FAQ
Does the ball landing on green affect the next spin?
No. Each spin is independent. The green pocket has the same probability on the next spin as it had on the previous one, and no sequence of red, black, or green results changes that. A player who believes the zero is due after a long absence is applying a pattern to a process that has none.
Can I bet on green as a colour in roulette?
No. The colour bets are red and black only, and the green pocket is outside both. A player who wants exposure to the zero must bet on it as a number, either straight-up or as part of a split, street, or other inside combination that includes it. The payout then follows the standard inside-bet schedule.
What is the difference between la partage and en prison when zero lands?
Both rules apply only to even-money bets and only when the single zero lands. La partage returns half the stake immediately and collects the other half. En prison holds the full stake for the next spin: a win returns the stake without profit, and a loss collects it. A table offering neither rule collects the full even-money stake when the zero lands.
