The 1-3-2-6 system is a “positive progression”: you bet 1 unit, and only if you win do you move to 3 units, then 2, then 6. A loss at any stage sends you straight back to 1 unit. It is a staking pattern, not a selection system. It decides how much to bet, never which bet is likely to win.
What a cycle actually nets
Assume even-money bets at decimal 2.00 and a £1 unit. Every possible outcome of one cycle, worked out exactly:
- Win all four (1, 3, 2, 6): +1 +3 +2 +6 = +12 units.
- Lose the first bet: −1 unit, reset.
- Win, then lose at 3: +1 −3 = −2 units, reset.
- Win, win, then lose at 2: +1 +3 −2 = +2 units, reset.
- Win, win, win, then lose at 6: +1 +3 +2 −6 = 0 units, reset.
The headline number is the +12. The fine print is that three of the five possible outcomes lose or return nothing, and the losing outcomes cluster where you feel most confident – after a couple of wins, when the sequence has you staking the largest amounts.
Why it cannot create an edge
Every single bet you place carries the bookmaker’s margin. At a typical even-money-style price of 1.96 (a 2% margin), a 1-unit bet won at a true 50% chance earns 0.96 and a loss costs 1.00: expected value = 0.5 × 0.96 − 0.5 × 1.00 = −0.02 per unit. That is negative, and it applies whether the unit is your first bet of the sequence or your sixth.
The sequence changes the order and size of the bets. It does not change their price. The expected value of a cycle is the sum of the expected values of its bets, so the cycle is negative too. Bigger bets later in the sequence mean the margin costs more exactly when you are staking the most: a loss at the 6-unit stage is worth six times as much as a loss at the 1-unit stage.
What it is actually good for
Used as a discipline tool, 1-3-2-6 has real value: it fixes your stakes in advance, it stops you doubling after a loss (unlike negative progressions such as Martingale), and the reset rule gives you a natural point to stop and re-evaluate. Paired with a session loss limit – for example, stop after two losing cycles – it bounds how much a bad session can cost. That is the honest benefit: controlled downside, not manufactured upside.
If you use it
- Set the unit at 1-2% of the money you have set aside for entertainment.
- Decide the stop in advance (a number of cycles or a loss limit) and honour it.
- Never skip ahead in the sequence because you feel “lucky” – the sequence only works as written.
- Never increase the unit size to recover previous losses.
- Use the deposit and loss limit tools in your account. Our safer gambling page lists them.
Verdict
1-3-2-6 is a reasonable way to structure stakes, and safer than chasing or doubling. It is not a way to beat the bookmaker: the margin is in every bet, the sequence cannot remove it, and the +12 cycle needs four straight wins to arrive. If you bet, let the system manage the stakes and the stop, and treat the rest as entertainment with a negative expectation.
