Six line bet in roulette: odds and payout on two rows
A six line covers two neighbouring rows, six numbers, and pays 5 to 1. It wins 16.22% of spins on a European wheel (1 in 6.2) and 15.79% on American, so the house keeps 2.70% and 5.26% of every stake.
Where the chip goes
Distinct placements: 11, one for each pair of neighbouring rows, from 1–6 to 31–36.
Odds and payout on both wheels
The win chance is pockets covered over pockets on the wheel. True odds are what the bet would have to pay for the house to make nothing; the gap between true odds and the actual payout is the edge.

The last row is where the expected loss grows past one standard deviation of luck; the house edge page derives it and compares every bet.
How often it hits
The chance of at least one hit in n spins is 1 − (1 − p)n. On average the bet comes in once every 6.2 spins on a European wheel. Half of all players see a hit within 4 spins, nine in ten within 14, and 99 in 100 within 27.
| Within | European | American |
|---|---|---|
| 1 spin | 16.22% | 15.79% |
| 5 spins | 58.71% | 57.65% |
| 10 spins | 82.95% | 82.07% |
| 25 spins | 98.80% | 98.64% |
| 37 spins | 99.86% | 99.83% |
| 50 spins | 99.99% | 99.98% |
| 100 spins | >99.99% | >99.99% |
| 200 spins | >99.99% | >99.99% |
Droughts
A drought is a run of spins without a hit. The chance that the next L spins all miss is (1 − p)L. Seeing a drought that long somewhere in a long session is far more likely, and the last column is computed exactly by dynamic programming over the current run of misses, not by simulation.
| Misses in a row | Next L spins | Somewhere in 1,000 spins |
|---|---|---|
| 12 | 11.965% | >99.99% |
| 19 | 3.468% | 99.81% |
| 31 | 0.415% | 48.84% |
| 49 | 0.017% | 2.63% |
| 74 | <0.001% | 0.03% |
Chance of being ahead after n spins
Flat stakes, the same bet every spin. After n spins with w wins the net is w × 6 − n stakes, and w is binomial, so these are exact sums. Breaking even counts as not ahead. The chances of winning page compares bets side by side and has a calculator for any session length.

Also called a double street
A six line is two streets under one chip, priced by the same formula as every other bet: 36 / 6 − 1 = 5 to 1. It is the largest inside bet. The next step up is a dozen at twelve numbers.
In the James Bond spread
The James Bond system puts 5 of its 20 units on the 13–18 six line, 14 on 19–36 and 1 on zero. Together they cover 25 numbers. The spread changes how often a session wins, not what each unit costs.
Systems built on this bet
Each runs over the same seeded sessions as every other system on the site. The figure is the result per $100 wagered on a European wheel.
| System | Per $100 wagered | In short |
