Martingale

Risk · High Negative Progression
In one paragraph

Double your bet after every loss to recover all prior losses plus one unit. Simple in theory, devastating in practice: a 7-step losing streak at 1x base risks 128 units to win one.

How the ladder moves

7 published steps · one unit = the base bet
1 lost 2 lost 4 lost 8 lost 16 lost 32 lost 64  

Win and loss are not recorded anywhere — they are read off the sequence. On a negative progression a bigger next bet means the one before it lost, and a smaller one means it won. The last step has nothing after it, so it carries no mark.

Works because

  • Extremely simple to execute manually or via autobet
  • Wins frequently in short sessions — satisfying short-run feel
  • Pairs well with rakeback: instant RB can offset the negative EV on low-edge dice
  • Works on virtually every provably-fair dice game

Breaks because

  • Catastrophic risk of ruin during any moderately long losing streak
  • Hidden max bets on Stake and others silently cap the bet before recovery is possible
  • Exponential bankroll growth requirement makes deep sequences impractical
  • Shadow autobet-stop limits truncate sequences mid-run on some platforms

No rakeback rate is published here, so $10.00 per $1,000 wagered is the gross edge — the real cost can only be lower, and we cannot say by how much. The published ladder reaches 64× the unit: run from this casino’s own $0.01 minimum that step is $0.64, against a $100,000 table max.

One seeded session, sampled at 12 points — the shape this system makes, not a forecast. It is not an average and not a projection: the dashed line is the $100 it started from, and the same settings run again land somewhere else entirely.

Variants

Common variants include the Grand Martingale (double + add one unit per step) and the Mini Martingale (cap at 3–4 steps to limit ruin). Both shift the risk/reward tradeoff but do not eliminate negative EV.

Problems & limits

Negative EV on any house-edge game without rakeback. Each doubling step risks exponentially more to recover one unit — table limits and hidden max bets cap recovery before the bankroll is restored.

FAQ

3 questions
What bankroll do I need to run Martingale safely?
You need at least 127x your base bet to survive a 7-loss sequence, and 255x to survive 8. Most practitioners use 500–1000x and cap at 7 steps to avoid the hidden max bet wall.
Does Martingale work on crypto dice?
In the short run it creates steady wins, but the math is unchanged: each session has the same negative EV. It only becomes net-positive if your rakeback percentage exceeds (house edge × turnover), which requires a very high instant rakeback casino.
Why does my autobet stop early on Stake?
Stake's autobet has an undocumented session-length limit that silently halts progression mid-sequence. You must restart the session manually or switch to a casino without this restriction.
