📚 What is the D’Alembert System?

The D’Alembert system was developed by French mathematician Jean le Rond d’Alembert in the 18th century. It is based on the belief that probabilities balance out over time and proposes a “gentler” betting progression than the Martingale.

🔧 How It Applies to Roulette

This system is used for near-50% bets (Red/Black, Even/Odd). The mechanics are simple:

• If you lose, increase your bet by one unit.
• If you win, decrease your bet by one unit.

The goal is to return to balance by slowly recovering losses.

🧠 What Logic Supports It?

D’Alembert believed in the balance principle: after many losses, wins should follow. But this ignores the statistical independence of each roulette spin.

📉 System Flaws

• 1. Smooths risk, but doesn’t eliminate it: Losses still add up, just more slowly.
• 2. Balance is an illusion: Roulette doesn’t correct past outcomes. Each spin is independent.
• 3. False sense of security: Because it’s less aggressive, players may let their guard down.

📊 Practical Example

You start betting 1 unit:

• Lose → bet 2
• Lose → bet 3
• Win → bet 2
• Win → bet 1

It works if wins alternate with losses. But with long losing streaks, the system still collapses.

🚫 Myths About Its Safety

Many believe D’Alembert is “safer” because bets don’t grow exponentially. But in reality, it still doesn’t change the house edge and can lead to long, unrecoverable losing streaks.

💡 Conclusion

The D’Alembert system is less aggressive than others, but that doesn’t make it effective. Based on a flawed idea of balance, it ultimately suffers from the same core issue: believing a progression system can beat a statistically unfavorable game.
