Labouchere Calculator

The Labouchere system plays a written line of numbers: bet the first plus the last, cross both off on a win, append the loss on a loss. This calculator prices a real line against a real casino — the exact chance it completes, where a losing streak kills it on your bankroll or the table max, and why no autobet can run it for you.

01Casino

No autobet can run this system. Labouchère needs list memory — cross off two numbers on a win, append the loss on a loss. No dice autobet has it, and Stake’s strategy builder has no variables either (checked live, July audit). Manual play only — or watch our simulator below run it in code.

Illustrative math, not advice: the house edge stays negative in both directions, and no line changes that. Preset limits and edges load from the same audited data as our dice simulator; the Generic chip is yours to fill in.

No casino autobet can execute this system — a simulator can. The strategy is preloaded below: pick a casino and hit RUN to watch the line grow and clear on a real seeded session.

Illustrative RNG simulation — every run is a fresh random session, not a prediction or a profit guarantee. Payout multipliers are rounded the way each casino’s own panel displays them: that is a model of what the panel shows, measured in-account, and not a rounding we have confirmed against a settled bet.

How to use the Labouchere calculator

  • Write your line. The default 1-2-3-4 targets $10 — a completed cycle banks the sum of the line at even money.
  • Pick your casino. Limits and house edge load from the same audited data our dice simulator uses.
  • Choose the direction. Classic crosses numbers off on wins and chases losses; Reverse crosses off on losses and caps one cycle's damage at the line's sum.
  • Set your win chance, bankroll and planned bets. The headlines show the exact completion odds and where the worst-case streak dies.
  • Read the table before you play: every step of a pure losing streak shows the bet, the money committed, and the odds of getting that deep.

Classic vs Reverse

Classic Labouchere chases losses: a loss appends its amount to the end of the line, so the line grows every time you lose. A win crosses off the first and last numbers instead, so the line clears one pair at a time. Completing it — crossing off the whole line — banks the sum of the original line at even money.

Reverse Labouchere flips the append/cross rule: a win appends its amount to the line, and a loss crosses off the first and last numbers. That caps the damage of any one losing streak at the line's sum, since losses only ever shrink the line — but a win streak keeps extending it, so a hot run can outrun the table max just as a bad one can in Classic.

Neither direction can be automated: dice autobets have no list memory, and Stake's strategy builder has no variables. The badge above the calculator is not marketing — it's the audit result. Our simulator runs the system in code, which is the only way to watch it play out.

Note: the completion odds use an unlimited-bankroll model — that’s the honest label for what every Labouchere simulator silently assumes. The ladder table and the survival number are where your real bankroll and the casino’s real table max enter. Where no table max is published, the tool says so rather than inventing a cap.

FAQ

Why can't any autobet run Labouchere?

Labouchere needs list memory — the system has to remember a whole line of numbers, cross off two on a win, and append one on a loss. We audited the autobet builders on the major casinos, including Stake’s, and none of them expose variables or list state; they only chain simple bet-size rules. That leaves manual play as the only way to run it at a casino — and our simulator below, which runs the system in code.

What does "the table max breaks the bookkeeping" mean?

It means the casino’s bet limit clamps a bet the line calls for, and that clamped bet no longer covers the pair it was supposed to cross off. Labouchere’s bookkeeping assumes every bet gets placed at full size; once the table max caps it, the line can grow on losses faster than a capped win can clear it — the system quietly stops matching its own math.

Does completing the line really bank the line's sum?

Yes, at even money: crossing off the whole line means every number in it was covered by a matching win, and the total banked equals the sum you wrote down. That identity is real math, not a promise — it only holds at an even-money payout. The parity line in the calculator gates the claim the moment your payout moves away from even money.

Where do the limits come from?

The same live casino data that powers our dice simulator — table max, minimum bet and house edge, pulled from published, audited sources and checked against the casinos’ real games.
