1-3-2-6 Calculator: The Controlled Streak System

The 1-3-2-6 system bets in a fixed sequence—1 unit, 3 units, 2 units, then 6 units—resetting after any loss or completing all four wins. Our calculator reveals why this structured approach limits maximum loss to 2 units while chasing 12-unit profits on winning streaks.

What Is the 1-3-2-6 System?

The 1-3-2-6 is a positive progression betting system where you follow a fixed sequence of bet sizes: 1 unit, then 3 units, then 2 units, then 6 units. Any loss resets to the beginning. Complete all four wins and pocket 12 units profit before resetting.

Quick Answer: 1-3-2-6 = bet 1 unit, win → bet 3, win → bet 2, win → bet 6, win → collect 12 units, reset. ANY loss = reset to 1 unit. Max loss: 2 units (if lose on bet 3 or 4). Most losses: 1 unit. Four wins needed for full profit. Structured, predictable progression.

How 1-3-2-6 Works

The Sequence Explained

1-3-2-6 progression:

Step 1: Bet 1 unit
WIN → Step 2: Bet 3 units (1+2 profit = 3)
WIN → Step 3: Bet 2 units (lock 4 profit)
WIN → Step 4: Bet 6 units (2+4 profit = 6)
WIN → Collect, reset

Total if all 4 win:
Won: 1 + 3 + 2 + 6 = 12 units

Loss Scenarios

Where losses hurt:

Lose at Step 1: -1 unit
Lose at Step 2: -2 units (won 1, lost 3)
Lose at Step 3: +2 units (won 4, lost 2)
Lose at Step 4: 0 units (won 6, lost 6)

Key insight:
Max loss is 2 units
Steps 3-4 use house money

Why 2 Before 6

The strategic dip:

1-3-2-6 vs 1-3-4-6:

Step 3 = 2 units (not 4)
Locks in 4 units profit
If Step 3 loses: Still +2 units

Conservative protection
Before the big Step 4 bet

Probability Analysis

Four-Win Probability

Chances of completing cycle:

At 48.65% per win:
Win 1: 48.65%
Win 2: 23.67%
Win 3: 11.52%
Win 4: 5.60%

Only 5.6% complete full cycle
But outcomes vary at each step

Expected Value Breakdown

EV per starting cycle:

Complete (5.60%): +12 units
Lose Step 4 (5.92%): 0 units
Lose Step 3 (12.15%): +2 units
Lose Step 2 (24.98%): -2 units
Lose Step 1 (51.35%): -1 unit

Weighted EV:
(0.056 × 12) + (0.059 × 0) + (0.122 × 2)
+ (0.250 × -2) + (0.514 × -1)

= 0.672 + 0 + 0.244 - 0.500 - 0.514
= -0.098 units per cycle

Same house edge, different structure

Loss Distribution

Common Mistakes

1. Wrong Sequence

Mistake: 1-2-3-6 or 1-3-4-6 Problem: Different risk profile Fix: Exactly 1-3-2-6

2. Not Resetting

Mistake: Continuing after loss Problem: Breaks the system Fix: Any loss = back to Step 1

3. Chasing Completion

Mistake: "I need to finish the cycle" Problem: Each bet is independent Fix: Reset immediately on loss

4. Wrong Unit Sizing

Mistake: $50 base with $200 bankroll Problem: Only 4 max-loss cycles Fix: Base = 1/20+ of bankroll
