The Wheel You're Sitting Down To
You sit at a roulette table in a casino and the first thing you notice is the wheel. On an American layout, that wheel has 38 pockets. The numbers run 0 through 36, and there are two green pockets: a single zero and a double zero. The presence of that second green pocket is the single fact that changes almost everything about how the game should be read, because it is not a neutral addition. It is an extra losing pocket on most bets, and it is the reason the American game charges a higher rate of loss than its European cousin.
The table itself mirrors the wheel. The betting felt shows the same numbers arranged in three columns of twelve, with the zero and double zero sitting at the head of the layout. Around those numbers sit the outside betting areas: red and black, odd and even, high and low, dozens, and columns. Every bet you can place is a wager on where the ball will land after the croupier spins the wheel in one direction and sends the ball travelling in the other.
What the Double Zero Does to the Odds
A European wheel has 37 pockets. An American wheel has 38. That one extra pocket is not cosmetic. On a straight-up bet covering a single number, a European wheel pays 35 to 1 against odds of 36 to 1. The American wheel pays the same 35 to 1, but the true odds against you are now 37 to 1. The payout did not improve; the difficulty did.
This is easiest to see on the even-money bets. Red and black each cover 18 numbers. On a European wheel, 18 red pockets and 18 black pockets leave only the single zero as the house's pocket. On an American wheel, the zero and the double zero are both green, which means both of them lose on red and both of them lose on black. The player still covers 18 numbers, but the wheel now has 20 pockets that beat the bet. The payout remains even money. The gap between the payout and the true odds is the house edge, and on the American layout that gap is wider on every bet that does not specifically include the double zero.
None of this changes the basic arithmetic of roulette. RTP and house edge sum to 100% for the same bet under the same rule set. A wider edge simply means the theoretical return over a very large number of spins is lower on the American wheel than on a single-zero wheel. In a short session, anything can happen. The wheel does not remember, and no pocket is ever due.
How a Round Plays
A round of American roulette has a clear sequence, and knowing it before you sit down prevents most of the confusion new players feel at the table.
First, you buy in. You place cash on the felt, never into the croupier's hand, and the croupier exchanges it for roulette chips. These chips are not the standard casino chips used at other tables. Roulette chips are colour-coded to you, and they have no denomination printed on them. Their value is set when you buy in, and they are worthless at any other table. When you finish, you must exchange them back at the roulette table before you leave.
Next, the croupier opens betting. You place chips on the layout. You may place as many bets as you like on a single spin, and you may combine inside and outside bets freely. Inside bets sit on the numbered grid or on its lines; outside bets sit in the boxes around the grid. While betting is open, you may move, add, or remove your chips.
Then the croupier closes betting, usually with a spoken call and a hand motion. From that moment, you may not touch the layout. The croupier spins the wheel and launches the ball. When the ball drops into a pocket, the croupier marks the winning number with a marker, clears all losing bets, and pays the winners. You do not collect your winnings until the croupier has finished paying; reaching onto the layout while chips are being paid is one of the fastest ways to irritate the table.
Only after all payouts are complete does the croupier open betting for the next spin. Your chips remain on the table until you remove them, and any winning bet that is not collected will be treated as a new bet on the next spin if you leave it in place.
The Bet Types and Where Their Edges Differ
Roulette bets split into two families. Inside bets sit on the numbered grid and pay more because they are less likely to win. Outside bets sit around the grid and pay less because they cover more of the wheel. The table below compares the main options on an American layout.
| Bet | What it covers | Payout | What changes on an American wheel |
|---|---|---|---|
| Straight-up | One number | 35 to 1 | Worse true odds: 37 losing pockets vs 36 on a single-zero wheel |
| Split | Two adjacent numbers | 17 to 1 | Same payout, two extra losing pockets |
| Street | Three numbers in a row | 11 to 1 | Same payout, edge wider than single-zero |
| Corner | Four numbers meeting at a corner | 8 to 1 | Same payout, edge wider than single-zero |
| Five-number | 0, 00, 1, 2, 3 | 6 to 1 | Exists only on American wheels; one of the worst bets on the layout |
| Red / black | 18 pockets of one colour | 1 to 1 | Both zero pockets lose; on a single-zero wheel only one does |
| Odd / even | 18 numbers | 1 to 1 | Same as red/black: both green pockets lose |
| High / low | 1-18 or 19-36 | 1 to 1 | Same as red/black: both green pockets lose |
| Dozen | 12 consecutive numbers | 2 to 1 | Same payout, edge wider than single-zero |
| Column | 12 numbers in one vertical column | 2 to 1 | Same payout, edge wider than single-zero |
The five-number bet deserves special attention because it exists only on the American layout. It covers the zero, the double zero, and the numbers 1, 2 and 3. The payout is 6 to 1, but the true odds against winning are worse than the payout implies, and the gap is larger than on any other single bet on the table. If you are learning the game, the simplest rule is to avoid it entirely. The even-money bets, by contrast, offer the gentlest rate of loss on the layout, but even they are more expensive on an American wheel than on a European one, because both green pockets stand against them.
The Decisions You Make
Roulette gives you no decisions after the ball is released. Everything you control happens before the spin. You choose which bets to place, how much to stake on each, and how long to stay at the table. No betting pattern changes the built-in edge of a negative-expectation game. A progression that doubles your stake after a loss does not remove the edge; it redistributes outcomes, so that most sessions end with a small win and a minority end with a large loss. The house edge on each bet remains exactly what it was.
What genuinely varies under your control is the rate at which you expose money to that edge. A session of straight-up bets on single numbers will produce long stretches of nothing and occasional large payouts. A session of even-money bets will produce frequent small wins and small losses, with the two green pockets quietly collecting on a regular basis. Neither approach is better in expectation; they differ in variance, not in return. The choice is about the shape of the session you want, not about improving the odds.
If the table offers a rule called surrender or en prison, read the posted rules before you rely on it. Some American layouts offer a version of surrender on even-money bets, where a losing bet to a zero pocket returns half the stake rather than the whole stake. Where it exists, it changes the effective edge on those specific bets. Where it does not exist, the bet loses in full. The rule is printed on the table or available from the croupier, and it differs from venue to venue.
Three Procedural Mistakes That Cost New Players
The first is touching chips after the croupier closes betting. The call is not a suggestion. Once the hand goes up and the words are spoken, the layout is frozen. A late bet or a moved chip will be returned or corrected, and repeated violations will get you a warning. Watch the croupier, not the wheel, for the close of betting.
The second is treating roulette chips like cash. They are not. They have no denomination, they are colour-coded to you, and they cannot be used at any other table or cashed at the cage. If you stand up and walk away with them, you are carrying plastic that has value only at the roulette table you just left. Exchange them before you leave the table.
The third is betting on the five-number basket because it sits at the top of the layout and looks like a natural group. It is not. It is the single worst bet on the American felt, and it exists only because the double zero creates a five-number cluster. If you want to cover the zeros, bet them as a split, which pays 17 to 1 for two numbers rather than 6 to 1 for five.
FAQ
Is American roulette harder to win than European roulette?
On a per-spin basis, yes, because the double zero adds a second green pocket that loses on most bets while the payouts stay the same. The difference shows up as a wider house edge on every bet except those that specifically include the double zero. In any single session, variance can overwhelm that difference, but over a very large number of spins the American layout returns less.
Can I bet on both zero and double zero at once?
Yes. The two green pockets sit adjacent on the layout, so a split bet placed on the line between them covers both numbers and pays 17 to 1. That is a far better way to cover the zeros than the five-number basket, which adds 1, 2 and 3 and pays only 6 to 1.
Why do roulette chips have no value printed on them?
Because they are assigned to you personally at the table where you bought in. The croupier sets their value when you buy in, and the colour lets the table track whose chips are whose. They cannot be used at other tables or cashed anywhere except the roulette table that issued them.
