Martingale System
The Martingale is perhaps the most famous betting system. It requires doubling your bet after every loss, theoretically recovering losses with a single win. Mathematically, this works in theory with unlimited capital and no betting limits. However, practical constraints make it problematic. Table limits prevent indefinite doubling, and a prolonged losing streak can exceed your bankroll. The expected value remains unchanged—the system merely redistributes when wins and losses occur.
