Test the D'Alembert betting system with our free interactive simulator. Explore this linear progression strategy that's considered less risky than Martingale while still facing the mathematical house edge.
Increase bet by one unit after loss, decrease by one unit after win
Linear progression makes it less aggressive than exponential systems
Even gentle progression cannot overcome the house edge
Increase your bet by one unit after a loss, decrease by one unit after a win. This system aims to balance wins and losses over time.
Named after French mathematician Jean le Rond d'Alembert, this system is based on the equilibrium theory that wins and losses should eventually balance out.
The system increases bets by one unit after losses and decreases by one unit after wins, creating a much gentler progression than exponential systems. However, it still cannot overcome the fundamental mathematical advantage held by the house.
While D'Alembert is less aggressive than other systems, it still cannot overcome the house edge. This simulator demonstrates why even the most conservative betting progressions fail long-term. Use for educational purposes only.
