Martingale strategy for crash games

The Martingale strategy in crash games turns a run of losses into one clean win: double after every loss, and the next 2x cash out wins it all back plus one base bet. It’s the oldest strategy there is: double your stake after every loss and go back to the base stake after a win. In crash games you pair it with a 2x auto cash out, because at 2x one win exactly recovers all previous losses plus one base bet. It’s part of our crash game strategy series. Here’s how to set it up and size it right.

How Martingale works at 2x

Round	Bet	Result	Running total
1	$10	Lose	−$10
2	$20	Lose	−$30
3	$40	Lose	−$70
4	$80	Win (2x)	+$10

Every cycle that ends in a win nets exactly +$10. That’s why it feels unbeatable at first.

Where it breaks

The bet doubles every loss: 10, 20, 40, 80, 160, 320, 640. After six losses you’ve staked $630, and the seventh bet needs $640 more. With a $500 bankroll you can’t place it, and the cycle ends in a large loss.

At 97% RTP you lose at 2x 51.5% of the time:

Losses in a row	Chance per cycle	Total staked
4	7.0%	$150
5	3.6%	$310
6	1.9%	$630
8	0.5%	$2,550

Each cycle is short, so you play many cycles per session. A 1.9% event in each of 50 cycles happens at least once in about 61% of sessions.

Simulation results

$500 bankroll, $10 base bet, 2x target, 97% RTP, 10,000 sessions:

• 100 rounds: median $0, bust rate 50.3%, but the 90th percentile finished at $1,030
• 1,000 rounds: bust rate 94.3%

The upside is real but rare. The downside arrives more often than it feels like it should.

Table limits

Casinos cap the maximum bet. Even with an unlimited bankroll, a long enough streak hits the cap, and from that point you can’t recover. The cap is one reason Martingale can’t work even in theory.

If you still want to try it

• Treat the whole bankroll as the stake, and expect to lose it.
• Use a stop-loss in auto-bet so you don’t refill and keep doubling.
• Compare it with Anti-Martingale, which keeps each loss to one unit, or flat betting at a fixed auto cash out.
