What is the 1-3-2-6 System?
The 1-3-2-6 system is a positive progression designed to maximize winning streaks while limiting losses. You bet 1 unit, then 3, then 2, then 6 โ but only advance after a win. Any loss sends you back to step one.
The math: Total bet across all 4 steps = 12 units. Total return if all 4 win = 24 units. Net profit for completed cycle: 12 units. Maximum loss: 2 units (losing at steps 3 or 4 after earlier wins).
How the 1-3-2-6 Progression Works
| Step | Bet | If Win (Running Total) | If Lose (Result) |
|---|---|---|---|
| 1 | 1 unit | +1, go to step 2 | -1, restart |
| 2 | 3 units | +4, go to step 3 | -2, restart |
| 3 | 2 units | +6, go to step 4 | +2, restart |
| 4 | 6 units | +12, restart | 0, restart |
Key Insight
After winning steps 1 and 2, you're guaranteed profit even if you lose step 3 or 4. Won $1 + $3 = $4. Step 3 bet is only $2. Worst case: still +$2.
All Possible Outcomes
| Result Pattern | Net Outcome | Probability (48% WR) |
|---|---|---|
| L | -1 unit | 52% |
| W-L | -2 units | 25% |
| W-W-L | +2 units | 12% |
| W-W-W-L | 0 units | 5.8% |
| W-W-W-W | +12 units | 5.3% |
You profit in W-W-L (12%) and W-W-W-W (5.3%) scenarios. That's 17.3% of cycles. But the +12 unit jackpot makes the math interesting.
10,000 Cycle Simulation
We simulated 10,000 1-3-2-6 cycles at 48% win rate:
| Outcome | Cycles | Total Units |
|---|---|---|
| L (lose 1) | 5,198 | -5,198 |
| W-L (lose 2) | 2,507 | -5,014 |
| W-W-L (win 2) | 1,201 | +2,402 |
| W-W-W-L (break even) | 578 | 0 |
| W-W-W-W (win 12) | 516 | +6,192 |
| Net | โ | -1,618 |
Average loss: 0.16 units per cycle. House edge still wins, but losses are extremely controlled.
Real Session Scenarios
Scenario 1: The Jackpot
W-W-W-W. Four consecutive wins. Bets: $10, $30, $20, $60. Returns: $20, $60, $40, $120. Total bet: $120. Total return: $240. Net: +$120 (12 units).
Scenario 2: The Safety Net
W-W-L. Win step 1 (+$10), win step 2 (+$30), lose step 3 (-$20). Net: +$20. Locked in profit despite losing. System working as designed.
Scenario 3: Early Exit
W-L. Win step 1 (+$10), lose step 2 (-$30). Net: -$20 (2 units). This is the worst outcome per cycle. Happens 25% of the time.
1-3-2-6 vs Paroli Comparison

Frequently Asked Questions
Why 1-3-2-6 and not 1-2-3-6?
The 2 at step 3 creates a safety net. After winning 1 and 3, you've profited 4 units. Betting only 2 at step 3 guarantees +2 even if you lose. The sequence is specifically designed for this protection.
Should I continue after completing 4 wins?
No. Always reset to step 1 after completing the cycle. Greed turns winners into losers.
Can I use larger starting units?
Yes. The ratios stay the same. $50 base = $50, $150, $100, $300 sequence. Just ensure your bankroll supports the $300 step 4 bet.
What's the minimum bankroll needed?
At least 20 base units. With $10 base, keep $200 minimum. This covers multiple W-L cycles (worst outcome) without depleting your bankroll.
