The bet that straddles two rows
On a roulette layout, the numbers sit in a grid of three columns and twelve rows. Most bets land on a single number, a single row, or a single column. A line bet is different: the chip sits on the outer corner where two adjacent rows meet, and it covers all six numbers in those two rows at once. That is what "on the line" means in roulette. It is sometimes called a six-line bet or a double street, and it is one of the inside bets, meaning it is placed on the numbered part of the layout rather than on the outside sections for red/black, odd/even, or high/low.
The placement is precise. The chip goes on the line at the end of the layout, where the two rows you want to cover meet the outer boundary. If it sits even slightly off that intersection, the dealer will read it as a different bet or ask you to move it. On a crowded table, the croupier may place the chip for you if you say the bet out loud, but knowing where it belongs keeps the round moving.
What a line bet covers
A line bet covers six numbers: the three numbers in one row plus the three numbers directly above or below them. For example, a chip placed on the line between the rows containing 1-2-3 and 4-5-6 covers all six of those numbers. If any one of them comes up, the bet wins. If any other number, the zero, or the double zero on an American wheel comes up, the bet loses.
The payout is fixed at 5 to 1. That means a winning line bet returns five units of profit for every one unit staked, plus the original stake back. The payout is the same on European and American wheels, but the odds of winning are not, because the American wheel has one extra pocket. The payout does not change; the chance of hitting one of your six numbers does.
How the house edge differs across the layout
Every bet on a roulette table carries its own mathematical edge, and the edge depends on the wheel type. On a European wheel with 37 pockets, a line bet covers six winning numbers out of 37, so it wins with probability 6/37. The 5-to-1 payout is slightly short of what a fair game would pay for that probability, and that shortfall is the house edge. On an American wheel with 38 pockets, the same bet wins with probability 6/38, and the edge is larger because the extra double-zero pocket takes away winning chances without changing the payout.
| Bet type | Numbers covered | Payout | Where it sits on the layout |
|---|---|---|---|
| Straight up | 1 | 35 to 1 | Directly on one number |
| Split | 2 | 17 to 1 | On the line between two numbers |
| Street | 3 | 11 to 1 | On the outer edge of one row |
| Corner | 4 | 8 to 1 | On the intersection of four numbers |
| Line (six line) | 6 | 5 to 1 | On the outer line between two rows |
| Column or dozen | 12 | 2 to 1 | In the outside boxes |
| Red/black, odd/even, high/low | 18 | 1 to 1 | In the outside boxes |
The table shows why the line bet is a middle ground among inside bets. It covers more numbers than a street or corner, so it wins more often, but it pays less when it does. That trade-off is the whole structure of the layout: more numbers covered means a smaller payout, and the house edge remains built into every one of those payouts.
The sequence of a round from buy-in to settlement
You buy in at the table with cash, and the dealer converts it into roulette chips. These are not the standard casino chips used at other tables; roulette chips are colour-coded to each player so the dealer can tell whose bets are whose on a crowded layout. You cannot cash roulette chips at the main cage. They must be exchanged back at the roulette table before you leave.
Once you have chips, you place them on the layout before the dealer calls for no more bets. The ball is already travelling around the wheel in the opposite direction to the wheel's spin. When the ball drops into a pocket, the dealer marks the winning number, clears all losing bets first, and then pays winning bets. A line bet that wins is paid at 5 to 1, and your original chip stays on the layout until you pick it up or the next round begins. If you do not touch it, it rides as the same bet for the next spin.
Where new players go wrong with a line bet
The first mistake is placement. A line bet chip must sit exactly on the outer boundary line between two rows. If it drifts onto the corner of four numbers, it becomes a corner bet covering only four numbers. If it sits on the line between two numbers, it becomes a split. The dealer reads the chip's position, not your intention, so a sloppy placement changes the bet, the coverage, and the payout.
The second mistake is assuming the payout changes with the wheel type. A line bet pays 5 to 1 on both European and American wheels. What changes is the probability of winning, because the American wheel adds a double-zero pocket. A player who moves from a European to an American table and keeps the same bets is accepting a larger house edge on every one of them without any increase in payout.
The third mistake is treating the line bet as a hedge. Because it covers six numbers, some players think of it as a safer version of a straight-up bet. It wins more often, but the payout is correspondingly smaller, and the house edge is unchanged. No combination of line bets, street bets, and outside bets removes the built-in edge on a negative-expectation game. The bets redistribute when and how much you lose or win in the short run; they do not change the long-run average.
Reading the table before you sit down
Before you place a line bet, check two things on the table itself. First, check the wheel type. A European wheel has a single zero and 37 pockets; an American wheel has a single zero and a double zero and 38 pockets. The layout usually shows the zero or zeros at the top of the numbered grid. Second, check the table minimum and maximum. A line bet is a single wager covering six numbers, so it counts as one unit toward the minimum, but the maximum applies to the total on that bet position. The posted limits are on a sign at the table, and they differ between tables and venues.
Some tables also have a racetrack layout for call bets, which are announced to the dealer rather than placed by hand. A line bet is not a call bet; it is placed directly on the main layout. If you are at a table with a racetrack, ignore it for this bet and place your chip on the numbered grid.
The decision points in a single spin
From the moment the dealer opens betting to the moment the next spin begins, you face a small number of decisions. The first is whether to bet at all. The second is which bet type to place, and the line bet is one option among many. The third is how much to stake on it, within the table limits. The fourth is whether to leave a winning bet in place for the next spin or take it down. None of these decisions changes the house edge on the bet you have chosen. They change your exposure, your session length, and the shape of your short-run results.
If you want to know the exact house edge for a line bet on the wheel in front of you, the arithmetic is simple: the payout is 5 to 1, the wheel has either 37 or 38 pockets, and the bet covers six of them. The edge is the difference between the true odds of winning and the payout the table offers. You do not need to memorise a percentage; you need to know the wheel type and the payout, both of which are printed on the table or visible on the wheel.
FAQ
Is a line bet the same as a street bet?
No. A street bet covers three numbers in a single row and pays 11 to 1. A line bet covers six numbers across two adjacent rows and pays 5 to 1. The chip positions are different: a street sits on the outer edge of one row, while a line sits on the outer boundary between two rows.
Can I place a line bet on the zero?
No. The zero and double zero sit outside the twelve-row grid, so no two-row combination includes them. A line bet always covers six numbers from the main grid. If you want to cover a zero along with other numbers, you would need a different bet type, such as a split or a straight-up bet on the zero itself.
Does a line bet win more often than a dozen bet?
No. A line bet covers six numbers, while a dozen or column bet covers twelve. The dozen bet wins more often and pays 2 to 1, while the line bet pays 5 to 1. The trade-off between coverage and payout is built into the layout, and the house edge remains on every bet regardless of how many numbers it covers.
