1-3-2-6 Roulette System: Lock In Profit With a Positive Sequence
Stake 1, 3, 2 then 6 units across four consecutive wins, banking profit partway through. A positive progression that keeps losses tiny and lets a hot streak pay.
- Type: positive progression
- Risk: low-moderate
- Best bet: even-money
The 1-3-2-6 is a fixed positive progression for even-money bets. You bet 1 unit; each win advances you to the next number in the sequence (3, then 2, then 6), and any loss resets you to 1. Because you only ever risk the base unit after a loss, and you lock in a guaranteed profit once you reach the third step, it has low bankroll pressure. It still carries the house edge, so the long-term expected value is negative.
Quick facts
| System type | Positive progression (fixed sequence) |
|---|---|
| Best known use | Riding a four-win streak on even-money |
| Typical bet type | Red/black, odd/even, high/low |
| Progression style | 1 - 3 - 2 - 6 units, reset on loss |
| Risk level | Low-moderate |
| Bankroll pressure | Low - losses cost the base unit |
| Table-limit pressure | Low - capped four-step run |
| Main weakness | Needs a full streak for the big payoff |
How the system works
The numbers 1, 3, 2 and 6 are units staked on consecutive wins. Win all four and you have gained 12 units for a maximum exposure of 2 units of your own money, because after the second win you pocket enough to cover the rest of the run. A loss at any step returns you to a 1-unit bet.
Step-by-step example
Unit = $5:
| Step | Bet | Win returns | Running profit |
|---|---|---|---|
| 1 (1u) | $5 | $10 | +$5 |
| 2 (3u) | $15 | $30 | +$10 (bank $10, keep $20 working) |
| 3 (2u) | $10 | $20 | +$20 |
| 4 (6u) | $30 | $60 | +$60 - sequence complete |
Notice that after step 2 you have locked in a profit, so even a loss on step 3 or 4 cannot turn the sequence into a net loss.
Best bet types for the system
Even-money outsides are the only sensible choice, since the sequence assumes a 1:1 payout and a near-50% win rate to give the streak a realistic chance of forming.
What happens during a losing streak
Very little. Each loss simply costs one base unit and resets the sequence. A cold run drains the bankroll slowly at the base rate, with no escalation - the opposite of Martingale's behaviour.
Bankroll and table-limit risk
Both are low. The largest bet in a $5-unit run is $30, so table limits are irrelevant and the bankroll erodes gently. The cost is opportunity: long stretches without a four-win streak pay nothing while the edge quietly applies.
European vs American roulette impact
Four-win streaks form a little less often on American wheels (47.4% even-money win rate vs 48.6%), and the edge is nearly double. Use European or French La Partage wheels.
Strengths and weaknesses
Strengths
- Losses capped at one unit
- Profit locked after step two
- No table-limit risk
- Simple fixed pattern
Weaknesses
- Big payoff needs a full streak
- Long dry spells erode funds
- Discipline to reset is essential
- Negative expected value
Who the system may suit
Cautious players who want low catastrophic risk and a clear, fixed plan, and who are happy to bank profit at step two rather than gamble it all on the final bet.
Who should avoid it
Players who cannot resist altering the sequence mid-run, or who expect frequent big wins - completed four-win runs are uncommon.
Testing advice
Decide whether you will bank after step two and stick to it. Compare its gentle curve with Paroli and Parlay in the showdown, and confirm the even-money EV with the odds calculator.

Frequently Asked Questions
Bet 1, 3, 2, 6 units on consecutive wins, banking the run after four. Any loss resets to 1 unit, and profit is locked after the second win.
Bankroll pressure is low - losses cost one unit and profit is secured early. It is still negative-EV long term.
Even-money bets, where the near-50% win rate gives the four-win run a realistic chance.
A loss on step one or three costs 1-2 units; a loss on step four still leaves the locked-in profit.
No. It shapes how wins compound but not the odds. Long-term EV stays negative.
