The 1-3-2-6 system is one of the oldest staking plans in betting, built around a simple idea: only increase your stake after a win, and drop straight back to your starting unit after any loss. It’s a positive progression, the opposite approach to systems like Martingale.
Loading calculator...
This calculator lets you run the sequence live, round by round, so you can see exactly how your stake, cumulative profit, and stage position move as wins and losses come in β instead of just reading about the pattern in the abstract.
It’s built for anyone using or considering the 1-3-2-6 system for even-money or near-even-money bets, and wanting a clear, real-time view of how it behaves.
π How to Use the 1-3-2-6 Calculator
Set your base unit stake, your currency, and the decimal odds you’re betting at. The stage reference table below updates instantly to show all four stake levels at those settings.
Click “Win” or “Loss” after each round exactly as it happens β the calculator advances, resets, or completes the sequence automatically based on your input.
Your cumulative profit and full round history update on the right after every click, and “Reset Sequence” starts a fresh run without losing your unit and odds settings.
π’ Calculator Fields Explained
Base Unit – your starting stake size, representing “1 unit” in the 1-3-2-6 sequence.
Currency – the currency symbol applied throughout the calculator.
Odds Being Bet – the decimal odds you’re betting at for each round in the sequence.
Win / Loss buttons – record the outcome of the current stage and advance the simulator to the next round.
π° Understanding the Results
| Result Field | What It Means |
|---|---|
| Stage (1 of 4) | Your current position in the 1-3-2-6 sequence |
| Next Stake | The stake required for the upcoming round at your current stage |
| Cycles Completed | How many full 1-3-2-6 sequences have been won start to finish |
| Cumulative Profit / Loss | Your running total across every recorded round so far |
| Round History | A log of every round’s stage, stake, result, and profit contribution |
A completed cycle is the system’s signature scenario, and it’s flagged directly in the round history whenever it happens.
A single loss at any stage resets the sequence entirely β the system does not “remember” progress from a prior partial run.
This reset behavior is exactly what limits the system’s downside compared to negative-progression systems like Martingale, but it also means a losing run never compounds stake size.
Only four consecutive wins complete one full 1-3-2-6 cycle β a single loss anywhere resets everything back to 1 unit.
π Calculation Formulas
| Stage | Stake (in units) | Condition to Reach It |
|---|---|---|
| Stage 1 | 1 unit | Start of sequence, or after any loss |
| Stage 2 | 3 units | After winning Stage 1 |
| Stage 3 | 2 units | After winning Stage 2 |
| Stage 4 | 6 units | After winning Stage 3 |
Profit per round is calculated as stake multiplied by (decimal odds minus one) on a win, or the full stake lost on a loss β standard even-money-style profit math applied at whatever odds you enter.
The 3-then-2 dip between Stage 2 and Stage 3 is deliberate: it locks in some profit from the first two wins before risking a larger Stage 4 stake.
This built-in profit-protection step is a defining feature that separates 1-3-2-6 from a simple doubling or tripling progression.
π Practical Examples
Example 1 β Full winning cycle: At a 10 unit base and 2.00 decimal odds, four straight wins (1, 3, 2, 6 units) produce a total profit of 120 across the cycle.
Example 2 β Loss on Stage 1: A single loss at Stage 1 costs exactly 1 unit (10), and the sequence immediately resets to Stage 1 for the next round.
Losses early in the sequence are cheap by design β the largest stake only appears after three consecutive wins.
Example 3 β Loss on Stage 4: Winning Stages 1-3 nets a running profit, but a loss on the 6-unit Stage 4 bet costs 60 units, which can erase most or all of that running profit.
Example 4 β Mixed run: Win, Win, Loss, Win, Win, Win, Win across seven rounds still ends with one completed cycle and a net positive result, despite the loss in the middle.
A loss on the final 6-unit stage can wipe out the entire profit built up over the first three winning stages.
π‘ Tips & Best Practices
Decide in advance whether you’ll follow the sequence exactly on every bet, since deviating mid-run undermines the system’s built-in risk structure.
Use the Reset Sequence button between genuinely separate betting sessions, not mid-sequence, so your history stays a true record of one continuous run.
Remember the system controls bet sizing, not bet selection β it doesn’t improve the accuracy of the underlying picks in any way.
Track multiple runs over time rather than judging the system from a single sequence, since any four-stage run is still a small sample.
Running a hypothetical sequence through the simulator before betting real money helps you understand the system’s rhythm without any risk.
Keep your base unit size proportionate to your total bankroll, since Stage 4 requires six times your starting unit at risk.
- Best suited to even-money or near-even-money markets
- Designed to protect capital during losing runs, not to guarantee profit
- Works with any odds, though the profit math changes with the price
If you’re new to progression systems generally, running several full sequences through this simulator before betting real stakes builds useful intuition.
β οΈ Common Mistakes to Avoid
Increasing the Base Unit Mid-Sequence
Changing your base unit partway through an active sequence breaks the intended stake ratios between stages and distorts the system’s risk profile.
Adjusting your base unit mid-sequence turns a controlled progression into an inconsistent, unplanned staking pattern.
Set your base unit before starting a run and leave it fixed until that sequence resets or completes.
Treating the System as Guaranteed Profit
No staking pattern changes the underlying probability of winning any individual bet β the sequence only controls how stakes scale with results.
A progression system manages stake sizing, not win probability β it cannot turn a losing selection process into a profitable one.
The system’s value lies entirely in disciplined bet sizing, not in any predictive edge over the market.
Restarting the Sequence After a Win Instead of a Loss
Some bettors mistakenly reset to Stage 1 after a win rather than advancing to the next stage, which defeats the compounding structure entirely.
Resetting after a win instead of a loss is the single most common way bettors misapply this system.
The sequence only resets on a loss; a win always advances forward through the stages.
Ignoring the Impact of Odds Below Even Money
The system’s classic profit figures assume roughly even-money pricing β using it at significantly shorter odds changes the profit math substantially.
Always enter the actual odds you’re betting at rather than assuming a flat 2.00 default applies to every market.
π― When to Use This Calculator
Use this tool any time you’re running or testing a 1-3-2-6 sequence and want a live, accurate view of stage position, stake size, and cumulative results as they happen.
A staking system’s real behavior only becomes clear when you watch it play out round by round, not just read its stage list on paper.
It’s also useful for reviewing a past betting session retroactively, entering each round’s actual result to see the sequence’s cumulative effect after the fact.

Decimal Odds – total payout per unit staked, including the stake itself.
Cumulative Profit – the running total gain or loss across all recorded rounds.
Bankroll – the total amount of money set aside for betting activity.
Variance – the natural short-term unpredictability of streaks of wins and losses.
Even Money – odds of roughly 2.00 decimal, where profit approximately equals stake on a win.
β Frequently Asked Questions
What happens if I lose on the very first round?
You simply lose your 1-unit base stake, and the sequence stays at Stage 1 for the next round since there’s nowhere lower to reset to.
This is the cheapest possible loss in the entire system, which is intentional β early losses are meant to be low-cost.
Does the 1-3-2-6 system work with any odds, or only even money?
It can be used at any odds, but the classic profit expectations associated with the system assume prices close to even money.
At significantly shorter odds, the profit from winning stages shrinks relative to the loss risked at Stage 4, changing the system’s overall risk-reward balance.
Always check the actual profit figures for your specific odds rather than relying on generic even-money examples.
What’s the difference between 1-3-2-6 and Martingale?
Martingale increases stakes after losses to chase back previous losses, while 1-3-2-6 only increases stakes after wins, resetting immediately on any loss.
This makes 1-3-2-6 considerably less risky to a bankroll during a losing streak, since stakes never escalate while losing.
Can I complete more than one full cycle in a row?
Yes β after a completed cycle, the sequence simply restarts at Stage 1, and a new cycle can begin immediately with the next round.
Consecutive completed cycles compound significantly, since each full cycle multiplies rather than adds to the bankroll’s growth.
Should I stop after a loss on Stage 4, or keep going?
The system itself simply resets to Stage 1 after any loss β whether to continue betting afterward is a personal bankroll and discipline decision, not part of the formula.
Some bettors set a fixed number of cycles or a session loss limit in advance, rather than deciding in the moment after a costly Stage 4 loss.

The 1-3-2-6 calculator is useful for tracking, but I’d only touch this with no-KYC crypto betting platforms using provably fair algorithms. Traditional fiat sportsbooks running this system? The house still has an edge on every single bet, and the sequence just masks that reality with prettier profit charts. Bitcoin wallets + Cloudbet or similar operators where you can verify the math yourself, that’s where positive progression actually means something. Fiat casinos? They’re collecting your data, running RNG blackboxes you can’t audit, and the 1-3-2-6 framework doesn’t change the fundamental math working against you. Speed matters tooβcrypto withdrawals settle in minutes, not the 3-5 business day delays traditional operators hide behind. If you’re serious about this system, ditch the regulated gatekeepers and use platforms where the math is transparent.
Regarding your point on provably fair verificationβyou’re right that cryptographic transparency is a meaningful advantage for certain operators. That said, the 1-3-2-6 system’s mathematical properties remain independent of the underlying bet verification method. The calculator itself works identically whether you’re using a no-KYC platform or a regulated operator: positive progression still requires four consecutive wins to complete a cycle, and a single loss at any stage resets back to 1 unit. What changes between platforms is regulatory oversight, withdrawal speed, and odds consistency, not the progression logic itself. Worth noting that UKGC-regulated operators (DraftKings, Bet365) actually offer better odds consistency and RTP transparency than many no-KYC platforms, which sometimes quote inflated decimal odds to attract players. The speed advantage you mention is real for crypto withdrawals, but traditional operators now offer same-day bank transfers in most jurisdictions. If your primary concern is edge verification, comparing the actual odds offered on equivalent matchups between platforms matters more than the betting framework you choose.
