Martingale starts with one unit on an even-money bet such as red. Double after a loss. After a win, return to the $1K base. A win on any allowed step recovers previous losing stakes in that cycle and leaves $1K net.
The following table assumes every earlier bet in the cycle lost. Cumulative exposure shows the sum lost if the current bet also loses; the winning-cycle result includes all preceding losses.
| Cycle bet | Required stake | Loss if all so far lose | Cycle net if this wins | Table status |
|---|---|---|---|---|
| 1 | $1,000 | $1,000 | +$1,000 | Allowed |
| 2 | $2,000 | $3,000 | +$1,000 | Allowed |
| 3 | $4,000 | $7,000 | +$1,000 | Allowed |
| 4 | $8,000 | $15,000 | +$1,000 | Allowed |
| 5 | $16,000 | $31,000 | +$1,000 | Allowed |
| 6 | $32,000 | $63,000 | +$1,000 | Allowed |
| 7 | $64,000 | $127,000 | +$1,000 | Allowed |
| 8 | $128,000 | $255,000 | +$1,000 | Allowed |
| 9 | $256,000 | Not placed | Cannot continue | Blocked: exceeds $200K |
RISK $255K. TARGET $1K.
Eight losing bets cost $1K + $2K + $4K + $8K + $16K + $32K + $64K + $128K = $255K. The next required $256K stake exceeds the $200K per-spot ceiling, even if you have enough money left.
You need at least $255K available at the beginning to fund all eight allowed bets on that losing path. A smaller bankroll stops the cycle earlier. Staking the maximum $200K after eight losses would recover only $200K on a win, leaving the cycle $55K down.
Each red bet wins on 18 pockets and loses on 19, because zero also loses. Eight consecutive losses from a specified starting point have probability (19/37)8, about 0.48%. That is not the chance of encountering a losing run somewhere in a longer session, which is a different calculation.
PRACTISE THE STOPPING RULE.
The 8-spin limit means eight bets in a single uninterrupted loss progression, not an eight-spin maximum session length. A win restarts the sequence. Stop if your bankroll or the spot cap cannot fund the next prescribed bet.
Our pattern calculator repeats a fixed stake, so it does not automatically run a Martingale progression. Use it to inspect a single step, or use the simulator’s Martingale system controls to practise changing stakes. The wheel remains independent on every spin.
Martingale is one of the best-known roulette betting systems because a successful cycle usually earns a small fixed amount. That pattern of small cycle wins comes with occasional large losses. The 2.70% house edge still applies to the total amount wagered.
