Anti-Martingale (Paroli) for crash games

Anti-Martingale, also called Paroli or reverse Martingale, turns the doubling idea around. After a win you bet the full return on the next round. After a loss, or after a set number of wins in a row, you reset to the base bet. It’s part of our crash game strategy series.

How a cycle works at 2x

Step	Bet	If it wins	If it loses
1	$10	$20 returned	−$10, reset
2	$20	$40 returned	−$10 net, reset
3	$40	$80 returned, bank it, reset	−$10 net, reset

Your own money at risk is always $10 per cycle. The rest is “house money” from earlier wins, though it’s still your money once you’ve won it.

Streak odds

At 97% RTP and 2x:

• One win: 48.5%
• Two in a row: 23.5%
• Three in a row: 11.4%

So about 89% of cycles end in a $10 loss, or in a smaller banked gain if you stop early. The 11% that complete pay +$70.

Simulation results

$500 bankroll, $10 base bet, 2x target, three-win cap, 100 rounds, 10,000 sessions:

Median	10th pct	90th pct	Bust
$440	$200	$700	1.2%

Compare that with flat betting at 2x (median $460, range $340–$600) and Martingale (median $0, bust 50%). Anti-Martingale trades a slightly lower median for a fatter upside, without Martingale’s total-loss tail.

Tips

• Set the streak cap before you start, and stick to it.
• Lower targets (1.5x) make streaks likelier but smaller. Higher targets make them rarer and bigger.
• Compare the results with Martingale and the 1.20x comparison in the simulator.
