Martingale vs Anti-Martingale vs fixed auto-cashout at 1.20x

Martingale vs Anti-Martingale vs a fixed 1.20x auto cash out: fixed 1.20x gives the smoothest ride, Martingale posts the best top-end sessions and Anti-Martingale caps every losing cycle at one base bet. This is the head-to-head comparison promised in our crash strategy pillar. We played all three at a 1.20x auto cash out with the same R2,500 bankroll and R50 base bet, over 10,000 simulated sessions each.

Every worked example on this page is in rand. The standard setup is a R2,500 session bankroll and R50 base bets (2%), the same ratios as our simulations. Funding a session? Ozow instant EFT is the quickest way in for most South African players.

Why 1.20x?

1.20x is one of the most-searched targets because it “almost always” lands. At 97% RTP:

• P(reach 1.20x) = 0.97 ÷ 1.2 = 80.8%
• Profit per win: R10 on a R50 bet
• Loss per miss: R50

So you need five wins to cover each loss, and five wins in a row at 80.8% happen only about 34% of the time.

The three systems

• Fixed: bet R50 every round.
• Martingale: after a loss, multiply the bet so one win recovers the loss. At 1.20x pure doubling doesn’t recover the loss (a R100 bet only wins R20), so true 1.20x Martingale needs ×6 escalation. Our simulator uses classic doubling, which recovers only partly at low targets. That makes the “recovery” weaker than people expect.
• Anti-Martingale: after a win, the next bet is the full R60 returned; reset after three wins or any loss.

What the numbers say

1. The typical session lands in the same place because each strategy bets a similar total at the same 97% RTP. Your choice is about how the session feels.
2. Martingale stretches both ends. Its best sessions beat flat betting (R2,710 vs R2,660), its rough ones dip lower (R1,840 vs R2,060), and a 0.5% bust rate is the price of that upside.
3. Anti-Martingale keeps losses capped at one base bet per cycle. At 1.20x the streak bonus is modest (three wins grow a R50 stake to R86.40), so it shines more at 2x and above.

Verdict

At 1.20x, flat betting is the smoothest default and a great place to start. Martingale gives you the best top-end sessions: pair it with a stop loss so a rare long run of reds can’t take the whole bankroll. Want upside with every loss capped? Anti-Martingale is your pick.
