How to Use

  • Step1
    Configure Your Settings
    Start by setting the following 4 items based on your bankroll.
    • Unit Amount: Enter your base bet (e.g. $10 or $50).
    • Currency: Select the currency you’re playing with.
    • Max Loss (Stop-Loss Limit): Set the maximum loss you’re willing to accept for risk management.
    • Starting Units: Set your initial bet level anywhere from 1 to 8 units.
      Starting at the default of 5 units is recommended.
  • Step2
    Start Betting with the Calculated Amount
    Tap “Start Game” and your first bet — based on your chosen starting units — will appear on screen.
    1. Place the displayed amount in your game.
    2. Tap [WIN] or [LOSE] on the tool based on the outcome.
    3. A loss increases your bet level by 1 unit. A win decreases it by 1 unit.
      Your current bet level is shown in real time in the “Current Bet Units” field.
      It displays in red when above your starting level and green when below.
  • Step3
    System Complete — Lock In Your Profit
    As wins accumulate and your bet level drops to 1, one more win brings it to zero — at which point the screen shows “Bet Amount Reached Zero! System Complete.”
    Even if you keep losing, the tool is designed to stop automatically one bet before your stop-loss limit is reached — so you can use it with confidence.

Tool Demonstration in Action

I actually used the tool and kept betting on Black in the Red/Black bet.

About the D’Alembert System

The D’Alembert system is a betting strategy built for the long game — bets go up by one unit after a loss and down by one after a win, keeping swings gentle and manageable.
For a manual walkthrough and a full breakdown of the logic, check out D’Alembert Betting System.
