D'Alembert vs Martingale: which wins in crash games?

D’Alembert vs Martingale: Martingale wins on the typical session, D’Alembert busts less often. D’Alembert says add one unit after a loss and take one unit off after a win, never going below one unit; Martingale says double your stake after every loss and go back to one unit after a win. In our 1,000-session test at 2x auto cash out with GH₵20 units and a GH₵1,000 bankroll, D’Alembert finished on a median of GH₵620 (44.9% busts) and Martingale on GH₵920 (46.5% busts). Here is the full comparison for Ghanaian players. Both are part of our crash game strategy guide.

D’Alembert vs Martingale: the rules

• D’Alembert: add one unit after a loss and take one unit off after a win, never going below one unit.
• Martingale: double your stake after every loss and go back to one unit after a win.

Both are negative progressions: they raise the stake after losses to win it back. The difference is how fast the stake grows.

How fast the stakes climb

After a run of losses at 2x, your next stake is:

Losses in a row	D’Alembert next stake	Martingale next stake
3	GH₵80	GH₵160
5	GH₵120	GH₵640
7	GH₵160	GH₵2,560

That growth rate decides everything. Our Martingale strategy crash guide explains why doubling recovers fastest and why it needs the deepest bankroll.
