The quickest way to understand the Martingale system is to watch the numbers move. Below are three progression tables, two worked session examples, and the total exposure at each step. You can reproduce every figure using the Martingale roulette calculator, and none of it changes the fact that a progression table does not make the system profitable.
Simple Martingale Roulette Example
The rule is simple: bet one base unit on an even-money outcome such as red. If you lose, double the next bet. If you win, collect the profit and reset to the base unit. Each completed cycle that ends in a win nets exactly one base unit, no matter how many doubling steps it took to get there. The catch is that every step you add multiplies both the stake and the amount at stake.
$1 Martingale Progression Table
| Loss Step | Bet | Cumulative Exposure |
|---|---|---|
| 1 | $1 | $1 |
| 2 | $2 | $3 |
| 3 | $4 | $7 |
| 4 | $8 | $15 |
| 5 | $16 | $31 |
| 6 | $32 | $63 |
| 7 | $64 | $127 |
| 8 | $128 | $255 |
$5 Martingale Progression Table
| Loss Step | Bet | Cumulative Exposure |
|---|---|---|
| 1 | $5 | $5 |
| 2 | $10 | $15 |
| 3 | $20 | $35 |
| 4 | $40 | $75 |
| 5 | $80 | $155 |
| 6 | $160 | $315 |
| 7 | $320 | $635 |
| 8 | $640 | $1,275 |
$10 Martingale Progression Table
| Loss Step | Bet | Cumulative Exposure |
|---|---|---|
| 1 | $10 | $10 |
| 2 | $20 | $30 |
| 3 | $40 | $70 |
| 4 | $80 | $150 |
| 5 | $160 | $310 |
| 6 | $320 | $630 |
| 7 | $640 | $1,270 |
| 8 | $1,280 | $2,550 |
The way you choose that first number is covered on the initial bet size page, and it matters more than most beginners expect.
Example: Winning After Three Losses
Say your base bet is $10. You lose spins one, two and three, betting $10, $20 and $40 for a running loss of $70. On the fourth spin you bet $80 and win, collecting $160. Subtract the $150 already staked on the first four bets and you finish the cycle $10 ahead: one base unit, exactly as designed. The sequence then resets to $10.
Example: Failing After a Long Losing Streak
Now imagine the same $10 base bet running into eight straight losses. By step eight the required bet is $1,280 and total exposure is $2,550. If either your bankroll or the table limits stop you before that winning spin arrives, the whole $2,550 is lost with no recovery. One failed sequence like this erases the profit from more than 250 successful $10 cycles.
Why the Required Stake Grows So Quickly
Doubling is exponential. Each step is larger than the sum of every step before it, which is why the cumulative exposure column climbs so steeply. This is also why the risk of ruin is concentrated in a small number of deep-streak outcomes rather than spread evenly across every spin.
How the Example Connects to Bankroll and Table Limits
The tables above show why bankroll planning is unavoidable. To survive eight losses at a $10 base bet you need over $2,550 available and a table that accepts a $1,280 bet. The bankroll requirements page turns this into a formula, and you can replay any of these sequences visually in the Martingale roulette simulator.
