Dive into the D’Alembert betting system, a method praised for its balanced approach to risk management. This strategy gradually adjusts bets, aiming for a safer gambling experience. Ideal for those seeking to extend their playtime while carefully navigating the ups and downs of casino games

Key information

  1. Fundamentals of the D’Alembert System: Named after French mathematician Jean le Rond d’Alembert, this is a negative progression strategy applied to even-money bets in games like roulette. It aims to mitigate losses and enhance winnings by adjusting bets based on the outcomes of previous rounds. Unlike the Martingale system, which suggests doubling the bet after a loss, the D’Alembert strategy advises increasing or decreasing the bet by a small, fixed amount.
  2. How to Apply the D’Alembert System: You start with a chosen initial bet and adjust your bet size by one unit after each game round, depending on whether you win or lose. The goal is to increase bets by one unit after a loss and decrease by one unit after a win, facilitating a slow progression in bet adjustments.
  3. Reverse D’Alembert System: As an alternative approach, the Reverse D’Alembert System advocates increasing the bet after wins and decreasing it after losses, aiming to capitalize on winning streaks.
  4. Effectiveness and Criticism: While some players advocate for the D’Alembert system for its structured approach to betting, critics argue that it cannot overcome the inherent house edge in casino games. Roulette outcomes are independent events, and thus, strategies based on the idea that wins and losses will eventually balance out may not be effective in guaranteeing profits.
  5. Legality: The D’Alembert system, like most betting strategies, is legal and accepted in casinos. It does not involve any form of cheating but rather a systematic approach to betting.
  6. Practicality and Risk Management: Although the D’Alembert system offers a structured way of betting, it’s crucial for players to gamble responsibly, set budgets, and understand that no betting strategy can assure consistent wins. The system can be applied not only in roulette but also in other casino games like baccarat and blackjack.
  7. Additional Roulette Strategies and Tips: Beyond the D’Alembert system, being informed about various bets in roulette, managing your bankroll wisely, and maintaining a realistic approach to gambling are essential strategies for enhancing your gaming experience.

Applying to Crash Games (e.g., JetX, Aviator, LuckyJet):

Crash games are online betting games where a multiplier increases until the game “crashes,” and you must cash out before that happens to win.

Strategy Application

  • Initial Bet: Choose a base amount (e.g., $5).
  • After a Game Crash (Loss): Increase your next bet to $6.
  • After a Successful Cashout (Win): Decrease your next bet to $5 (or $4 if following a win after an increase).

Example with JetX

GameOutcomeBet SizeNext Bet Size (Standard)
1Crash (Loss)$5$6
2Successful Cashout (Win)$6$5
3Crash (Loss)$5$6
4Successful Cashout (Win)$6$5

Key Points to Remember:

  • This strategy is legal and widely used in casinos.
  • It offers a systematic approach to betting, aiming for a slow and steady management of your bankroll.
  • No strategy guarantees consistent wins; roulette and crash games are games of chance.
  • Responsible gambling is crucial. Set a budget and stick to it.


The D’Alembert Strategy, whether in roulette or crash games, promotes a balanced approach to betting, increasing after losses and decreasing after wins. While it provides structure, remember the importance of managing your bankroll and gambling responsibly.


Which betting system is better Dalambert or Martingale ?

Deciding whether the D’Alembert or Martingale betting system is better depends on your goals, risk tolerance, and bankroll. Here’s a simple comparison:

Martingale System

  • Risk Level: High. Requires doubling bets after each loss.
  • Bankroll Requirement: High. You need a significant bankroll to sustain multiple losses.
  • Recovery Speed: Fast. A single win recovers all previous losses plus the original bet amount.
  • Best For: Players looking for quick recovery and who are comfortable with high risk.

D’Alembert System

  • Risk Level: Lower than Martingale. Increases bets by a fixed amount after a loss and decreases after a win.
  • Bankroll Requirement: Moderate. Less aggressive than Martingale, so it doesn’t deplete funds as quickly.
  • Recovery Speed: Slower. Gradual increases mean slower recovery of losses.
  • Best For: Players seeking a more conservative approach, with lower risk and steadier play.

Key Considerations

  1. Martingale is better for short-term play with a high-risk, high-reward approach.
  2. D’Alembert suits players looking for a less risky strategy, ideal for longer sessions with a moderate bankroll.
