The Betting Layout Looks Busier Than It Is
A roulette table can intimidate a first-time player. The felt is covered in numbers, red and black diamonds, and words like 'manque' and 'impair' on some layouts. But every chip you can place falls into one of two families: inside bets, which sit on the numbered grid, and outside bets, which sit in the boxes around the grid. The number of distinct ways to bet is finite, and once you see how the layout groups them, the whole table becomes readable in about five minutes.
The first thing to understand is that the wheel and the layout are two views of the same thing. The wheel is where the ball lands; the layout is where you state your prediction. Every bet is a prediction about where the ball will stop, expressed as a set of numbers. A bet on a single number covers one pocket. A bet on red covers eighteen. The payout shrinks as the coverage grows, because the bet becomes easier to win.
Inside Bets: The Numbered Grid
Inside bets are placed on the numbered part of the layout, the rectangle containing the numbers 1 through 36 arranged in three columns of twelve rows, with the zero (and double zero on an American wheel) sitting at the top. These bets cover specific numbers or small groups of them. They pay more because they are harder to hit.
A straight-up bet is a chip placed entirely inside one number's box. It covers exactly one pocket. A split bet sits on the line between two adjacent numbers and covers both. A street bet sits on the outer edge of a row and covers all three numbers in that row. A corner bet sits on the intersection of four numbers and covers that square. A six-line bet sits on the outer corner where two rows meet and covers six numbers. On American layouts, a five-number bet covers the zero, double zero, one, two and three, and it carries the worst odds on the table.
The payout for each inside bet is fixed by the table rules and printed on the layout or in the game information panel. The fewer numbers a bet covers, the larger the multiple it pays. A straight-up bet pays the most; a six-line bet pays the least of the standard inside bets.
| Bet name | Numbers covered | Where the chip sits | Relative payout |
|---|---|---|---|
| Straight-up | 1 | Inside one number's box | Highest |
| Split | 2 | On the line between two numbers | High |
| Street | 3 | On the outer edge of a row | Medium-high |
| Corner | 4 | On the intersection of four numbers | Medium |
| Six-line | 6 | On the outer corner between two rows | Low for an inside bet |
| Five-number (American only) | 5 | On the corner covering 0, 00, 1, 2, 3 | Worst odds on the layout |
Outside Bets: The Boxes Around the Grid
Outside bets sit in the boxes surrounding the numbered grid. They cover large groups of numbers and pay less than inside bets, because the probability of winning is higher. They are the bets most new players start with, and for good reason: they are simpler to read and their outcomes arrive more steadily.
The even-money bets are red or black, odd or even, and low (1-18) or high (19-36). Each covers eighteen numbers. The dozen bets cover the first, second or third block of twelve numbers. The column bets cover one of the three vertical columns of twelve numbers. On some layouts, you will also see announced or call bets such as 'voisins du zero' or 'tiers du cylindre', which cover fixed sections of the wheel rather than the layout. These are more common on European tables and may be placed through a separate racetrack-shaped diagram printed beside the main grid.
One procedural point matters here: a chip placed on the line between two outside boxes is not a valid bet. Outside bets must sit fully inside their box. A chip straddling the line between red and odd, for example, will be returned or moved by the dealer before the spin, because the table cannot interpret a half-outside bet.
| Bet name | Numbers covered | Payout type | What it means |
|---|---|---|---|
| Red or black | 18 | Even money | Ball lands on that colour |
| Odd or even | 18 | Even money | Ball lands on that parity |
| Low or high | 18 | Even money | Ball lands 1-18 or 19-36 |
| Dozen | 12 | 2 to 1 | Ball lands in that block of twelve |
| Column | 12 | 2 to 1 | Ball lands in that vertical column |
How the Wheel Type Changes Every Bet
Roulette wheels come in two main configurations, and the difference is not cosmetic. A European wheel has 37 pockets: the numbers 1 through 36 plus a single zero. An American wheel has 38 pockets: the same 36 numbers plus a single zero and a double zero. That extra pocket is the entire story of why the two games feel different.
The house edge on any roulette bet comes from the zero pockets. When the ball lands in zero, most outside bets lose, and most inside bets lose unless they specifically covered the zero. On a European wheel, one pocket out of 37 belongs to the house's advantage on those bets. On an American wheel, two pockets out of 38 do. The American layout therefore carries a larger built-in edge on the same bet, because the extra zero adds a losing outcome without adding a compensating payout.
This does not mean one wheel is 'better' in the sense of promising a win. It means the expected rate of loss differs. A player choosing between two tables should read the wheel type as a cost difference, not a luck difference. The wheel type is printed on the layout or shown in the game information panel, and the number of pockets is visible on the wheel itself before you sit down.
How a Round Runs
You buy in at the table by placing cash on the felt; the dealer exchanges it for roulette chips. Roulette chips are often colour-coded per player so the dealer can tell whose bets are whose when several people play the same numbers. You state your bet by placing chips on the layout before the dealer calls for no more bets.
The dealer spins the wheel in one direction and sends the ball travelling the other way around the outer track. When the ball drops into a pocket, the dealer places a marker on the winning number, clears all losing bets, and pays winning bets from the outside in. You do not touch your chips while the marker is on the layout. When the marker is removed, the next round opens and you may place new bets or adjust existing ones.
The sequence is the same online, minus the physical chips. You select a chip value, click the layout to place bets, and press spin. The software settles the round instantly and returns winnings to your balance. The bet types, payouts and wheel mechanics are identical; only the interface changes.
Three Procedural Mistakes That Slow New Players Down
The first is late betting. Once the dealer calls no more bets, any chip that lands on the layout is void for that spin. If your hand is still hovering when the call comes, you have missed the round. Decide your bet before the ball slows, not while it is dropping.
The second is mixing chip values without noticing. Online, the interface prevents most errors. At a live table, a stack of low-value chips placed on a straight-up number is a different bet from a single high-value chip on the same number. Count what you are putting down, and watch the dealer's confirmation before the spin.
The third is assuming a losing streak means a number is due. Each spin is an independent event. The wheel has no memory, and no sequence of reds makes black more likely on the next spin. The odds of any given bet are the same on every spin, set by the wheel's pockets and the bet's coverage, not by what happened in the last ten minutes.
FAQ
What is the safest bet in roulette?
No bet is safe in the sense of avoiding loss. The even-money outside bets cover the most numbers, so they win more often than inside bets, but they pay less and still lose to the zero pockets over the long run. The relevant comparison is the house edge on the wheel you are playing, not the name of the bet.
Can I bet on every number at once?
You can place chips on every number, but the result is a guaranteed loss on that spin. The total payout for the winning number will be less than the total amount you staked across all numbers, because the payouts are set below the true odds. The zero pockets make the gap wider.
Why do some roulette tables have a double zero?
The double zero is a feature of the American wheel configuration. It adds a thirty-eighth pocket, which increases the house edge on most bets compared with a single-zero European wheel. The wheel type is shown on the layout or in the game information panel, and it changes the expected rate of loss on every bet you place.
