Martingale simulator
The calculator above tells you how likely the killer streak is. The simulator lets you watch it happen: one click runs a full Martingale autobet session on dice, and every run is a fresh seeded session you can share.

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 martingale calculator
The calculator answers one question: how deep can your bankroll go before a losing streak wipes it out.
- Enter your bankroll and base bet. The ratio between them decides survival, not the absolute amounts.
- Pick your casino and win chance to load the real payout multiplier, then set the On-loss % separately — that split is the whole point of the tool. Watch the f* chip: it shows the exact On-loss % that fully recovers a loss at your chosen payout, so you can see at a glance whether your own setting under- or over-presses the ladder.
- Steps survivable and Last-step bet are the core: how many losses in a row the ladder absorbs, and the size of the final bet in it. It is usually the second number that shocks people.
- Balance utilization is the optimizer part: at 63% you can raise the base bet about 1.5× and still survive the same six losses — the ladder just fits your bankroll tighter.
- Sequence odds and Critical event translate risk into time: how likely the killer streak is within an hour at your betting speed.
- Profit per day is negative by default — that is the house edge working. Add your rakeback percent to see what it takes to break even.
- The progression table under the metrics lays the ladder out rung by rung: the bet, the money sunk by that point, and the chance a streak even takes you there.
- Set a target profit and the calculator shows your odds of banking it before the ladder breaks — Success probability against Risk of ruin.
Why check the numbers first
Martingale feels safe because each individual bust is unlikely. The calculator shows how unlikely — and what it costs to keep the streak survivable. The theory and the variants are in the martingale strategy breakdown, table limits for each site are in the dice game reviews, and the dice simulator lets you watch full sessions play out, bust included.
Does this work for games other than dice?
Yes. The math only needs a win chance and a payout multiplier, so roulette or crash bets fit too. The defaults just assume a dice-style 2× bet.
Why is profit per day negative?
Because every bet pays slightly less than fair odds — that is the house edge. No progression changes it. Rakeback is the one lever that can: enter your real rate and the calculator shows whether it covers the grind.
What is risk of ruin?
The chance your bankroll dies before it reaches the target. This calculator recounts the ladder after every won cycle, because a slightly bigger bankroll sometimes affords one more step. Fixed-depth calculators skip that and overstate the risk a little on the classic doubling ladder.
The payout is the casino’s — the ladder is yours
These are two different numbers doing two different jobs. The payout multiplier is priced by the casino — chance times payout nets out to the house edge on every bet, no matter what you do afterward. The On-loss % is yours to set: it is how hard the ladder presses after a loss, and it only has to match the payout at one specific point. At a 2× payout, doubling the bet happens to be exactly the recovery size, which is why classic martingale looks like a single rule. At any other payout m, full recovery needs an On-loss % of m/(m−1) — a different number for every multiplier.
That is what the f* chip is for. It computes m/(m−1) for whichever payout your casino and win chance produce, so you can set your own On-loss % against it instead of guessing. Match it and every recovered rung banks a clean, constant profit; go below it and a win no longer fully clears the previous loss; go above it and you are pressing harder — and risking more — than the recovery strictly requires.
FAQ
Is the payout multiplier the same as the martingale doubling?
No — they answer different questions. The payout multiplier is the casino’s price for the bet: chance times payout always nets out to the house edge, on every single wager. The on-loss percent is your strategy: how hard you press the ladder after a loss. The two only happen to coincide at a 2× payout, where doubling the bet is also exactly the recovery size. At any other payout m, full recovery of the last loss needs an on-loss percent of m/(m−1) — press less than that and a win no longer clears the hole; press more and you are overpaying to recover it.
What stops the ladder — bankroll or the casino?
Either one can, and the calculator prices both ceilings. Your bankroll runs out when the next rung’s stake is bigger than what is left — that is the survivable-steps number above. But some casinos cap the ladder first: Stake’s autobet enforces a $100,000 profit-cap rule, which at a 99× payout bet caps the maximum useful bet at roughly $1,020 — well before most bankrolls would. Whichever ceiling is lower is the one that actually ends your session.
Does rakeback make martingale profitable?
It can close most of the gap, never flip the sign on its own — and it depends on the program type. Wager-based programs (Stake VIP, Duelbits’ Ace’s Rewards, Shuffle, Roobet) pay back a percent of everything you stake, win or lose, so a martingale ladder’s huge total volume earns real rebate — that is the one lever that scales with the grind. Loss-based cashback (BC.Game, DuckDice) only pays back a slice of net losses, so it cannot be farmed by staking more; it just softens bad sessions after the fact. Enter your real rate and the calculator’s profit-per-day line shows the EV math directly.
Why does Profit-if-win drift when I change the on-loss percent?
Because the ladder table’s Profit-if-win column is only a flat, constant one base bet when your on-loss percent exactly equals the recovery value f* = m/(m−1) for the chosen payout. Set the on-loss percent below f* and each recovered rung banks less than a full base bet, because the escalation under-presses the hole left by the previous loss; set it above f* and each recovery banks more, because you are pressing harder than strictly needed to clear it. The column is drawn straight from the real cumulative stake at every rung, so it shows that drift honestly instead of assuming the classic 2× shorthand always applies.
Are these real casino numbers?
Yes. Every casino chip in the calculator — house edge, payout limits, max bet, profit caps — comes from the same live, audited preset data the dice simulator uses, not a generic textbook table. When a limit changes on a casino’s side, both tools update from the one source together.
