The payout is fixed, but the wheel under it is not
A six-line bet, sometimes called a double street, places a single wager across six numbers arranged in two adjacent rows of three. The chip sits on the outer corner where the two rows meet. The payout for this bet is 5 to 1: a winning spin returns five units of profit for every one unit staked, plus the original stake comes back. That ratio does not change between wheels or casinos, because it is built into the geometry of the bet itself.
What does change is the chance that the bet wins. On a European wheel with 37 pockets, six numbers out of 37 win. On an American wheel with 38 pockets, the same six numbers face one extra losing pocket, the double zero. The payout is identical on both wheels. The player's expected loss per unit wagered is not. That distinction, between a fixed payout and a wheel-dependent probability, is the first thing to hold onto when comparing any roulette bet.
Where a six-line bet sits on the layout
Roulette inside bets are defined by how many numbers they cover and how they are positioned on the felt. The six-line covers two streets at once. A street is a single row of three consecutive numbers, such as 1-2-3 or 4-5-6. Placing a chip on the line at the end of a row covers that street. Placing it on the corner where two rows meet covers both streets, six numbers in total.
The bet loses unless one of those six numbers appears. Zero and double zero are not covered unless the player places a separate wager on them. That matters because the zero pockets are exactly where the house edge lives on the layout.
Inside bets compared
Every inside bet pays according to the number of pockets it covers, but the payout is always slightly short of what a fair wheel would offer. A straight-up bet on one number pays 35 to 1, yet on a European wheel the true odds against winning are 36 to 1. The gap between the payout and the true odds is the house edge.
| Bet | Numbers covered | Payout | True odds against (European wheel) |
|---|---|---|---|
| Straight up | 1 | 35 to 1 | 36 to 1 |
| Split | 2 | 17 to 1 | 17.5 to 1 |
| Street | 3 | 11 to 1 | 11.33 to 1 |
| Corner | 4 | 8 to 1 | 8.25 to 1 |
| Six line | 6 | 5 to 1 | 5.17 to 1 |
The table shows why no inside bet is better than another in the sense of removing the edge. The six-line bet wins more often than a straight-up bet, but it pays proportionally less. A player covering six numbers with a single six-line wager faces the same house edge as a player covering six numbers with six separate straight-up bets, assuming the same wheel and the same total stake. What changes is variance: the six-line bet produces smaller, more frequent swings than a single number.
How the wheel changes the same bet
The European wheel has 37 pockets and a single zero. The American wheel has 38 pockets with a single and double zero. The six-line bet covers six numbers on either wheel. The payout stays 5 to 1. The extra pocket on the American layout means the bet wins slightly less often, which increases the house edge on every inside bet, including the six-line.
Some tables offer a rule variant that changes how losing bets behave when the ball lands in zero. On certain European tables, a rule may return half the stake on even-money outside bets when zero appears, or hold the stake for the next spin. That rule applies to outside bets such as red or black, not to inside bets like the six-line. A player checking a table's edge should read the posted rules for that specific table, because rule variants change the arithmetic even when the payout ratios stay the same.
The sequence of a round
A roulette round moves through a fixed sequence. The dealer opens betting, players place chips on the layout, and the dealer closes betting before the ball is released. Once the ball is in motion, no further bets may be placed or changed. The ball settles in a pocket, the dealer marks the winning number, and losing chips are cleared before winning bets are paid.
For a six-line bet, the player places a single chip on the outer corner where the two chosen rows meet. If any of the six numbers in those rows wins, the dealer pays 5 to 1 on that wager. If the ball lands elsewhere, the chip is collected with all other losing bets. There is no decision point during the spin itself. The only choices happen before the dealer closes betting: which numbers to cover, how many units to stake, and whether to combine the six-line with other wagers.
What players commonly misread
The first mistake is treating the 5 to 1 payout as a statement about how often the bet wins. Six numbers out of 37 on a European wheel means the bet loses 31 times and wins 6 times across a representative run of 37 spins. The payout does not compensate for those 31 losses. The second mistake is assuming that covering more numbers reduces the house edge. It reduces the frequency of losing spins, but the payout shrinks in proportion, so the expected loss per unit wagered stays the same on a given wheel.
The third mistake is placing a six-line bet without checking which wheel is in play. The same wager on an American layout carries a larger house edge because of the double zero. A player who wants to know the exact edge for the table in front of them should look at the wheel itself: 37 pockets means a single-zero wheel, 38 means a double-zero wheel. That single observation changes the arithmetic more than any choice of inside bet.
FAQ
Does a six-line bet pay differently on an American wheel?
The payout is the same 5 to 1 on both wheel types. The difference is the chance of winning, because the American wheel has one extra pocket that the six-line bet does not cover. That extra pocket increases the house edge without changing the payout ratio.
Can I place a six-line bet that includes zero?
No. The zero and double zero sit apart from the numbered rows, so a six-line bet cannot include them. A player who wants to cover zero must place a separate wager on it, and that wager carries its own payout and its own probability.
Is a six-line bet better than three split bets covering the same numbers?
Both approaches cover six numbers and both carry the same house edge on the same wheel when the total stake is equal. The difference is in how the payouts arrive. A six-line bet pays once at 5 to 1 when any covered number wins. Three split bets pay individually at 17 to 1 on the winning split while the other two lose. The expected loss is the same; the sequence of wins and losses feels different.
