A six-line bet is a roulette wager on six numbers across two adjacent horizontal rows. It is also called a double street. The chip is placed where the two rows meet at the outside edge of the number layout, and the bet usually pays 5 to 1.
Plain Talk
A six-line bet is two street bets joined together. Instead of covering one row of three numbers, it covers two neighboring rows: for example, 1-2-3-4-5-6 or 13-14-15-16-17-18.
It hits more often than smaller inside bets, but the payout is smaller. That does not make it a better bet mathematically. It makes it a lower-volatility version of inside roulette play.

| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Six-line bet | Six-number inside bet | Outside edge of number grid | Covers two adjacent streets |
| Double street | Another name for six-line bet | Dealer/player language | Same bet, different wording |
| 5 to 1 | Usual payout | Roulette paytable | Lower payout for wider coverage |
| Hit frequency | How often the bet wins | Roulette math | Higher than small inside bets |
Where You See It
You see six-line bets on the outside edge of the inside number grid. A chip is placed between two streets to cover all six numbers in those rows. In online roulette, this position often highlights six numbers before the bet is confirmed.
Why It Matters
The six-line bet matters because it is the widest normal inside bet. It gives the player six covered numbers while still feeling like a number-grid bet, not a broad outside bet.
That creates a common trap: players see more hits and may mistake that for stronger math. But on a standard wheel, the house edge is still driven by the zero or zeroes.
Example
A player puts $10 on the six-line covering 25-26-27-28-29-30.
If any one of those six numbers lands, the player wins $50 profit. If any other number lands, the player loses $10.
On a European wheel, the bet covers 6 of 37 pockets. On an American wheel, it covers 6 of 38 pockets.
From the Casino Side:
From the casino side, six-line bets are fast to book but can create layout congestion, especially when players stack multiple chips over neighboring streets, corners, and splits. Dealers must announce, mark, pay, and clear them cleanly.
For surveillance, the concern is not that the bet is mathematically unusual. The concern is placement accuracy, late betting, dealer error, payout error, and disputes over whether the chip was meant as a street, corner, or six-line wager.
Common Misunderstanding
The biggest misunderstanding is that a six-line bet is “almost an outside bet.” It is still an inside bet because it sits on the number grid and pays according to covered numbers, not broad categories like red/black or dozens.
Another misunderstanding is that it reduces the casino edge. It reduces swing compared with straight-up bets, but it does not remove the built-in disadvantage.
Hard Truth
A six-line bet can make roulette feel calmer, but the wheel is still charging the same price for the spin.

The six-line bet shows how roulette changes volatility without changing long-term disadvantage. Six covered numbers create more wins than a straight-up bet, but the payout is adjusted downward.
Formula / Calculation
| Wheel | Winning numbers | Usual payout | House edge |
|---|---|---|---|
| European roulette | 6 / 37 | 5 to 1 | 2.70% |
| American roulette | 6 / 38 | 5 to 1 | 5.26% |
Expected value for a $1 American six-line bet:
EV = (6/38 × $5) - (32/38 × $1)
EV = -$0.0526
Formula Explanation in Plain English
Six numbers win $5 each way, and the rest lose $1. The payout looks balanced until the zero pockets are counted. Those pockets are what keep the casino edge in the game.
