A betting system where you double your bet after every loss, attempting to recover losses with one win.
The Martingale system is a progressive betting strategy: you double your bet after each loss, so that one win recovers all previous losses plus your original bet amount. It's the most well-known betting system and one of the most dangerous.
The problem with Martingale is that it requires an unlimited bankroll and no table limits — neither of which exists. A losing streak of 7-8 bets can require wagers exceeding table maximums, leaving you unable to recover. At a $10 starting bet, 10 consecutive losses would require a $10,240 bet.
Martingale does not change the house edge. Over time, you will lose exactly what the math dictates. The system just changes the distribution of outcomes: many small wins and rare but catastrophic losses.
You bet $10 on black at Harrahs roulette. It loses, so you double to $20. Loses again — $40. Then $80, $160, $320. After six straight losses you are $630 in the hole and must bet $640 next to recover $10 profit.
The strategy collapses against table limits and bankroll depth. A $10 minimum, $500 maximum roulette table caps the Martingale at six doubles — and the probability of six reds in a row on an American wheel is 1.9%, which happens multiple times per session. Over 1,000 spins, a Martingale player typically wins 98% of sessions by $10 and loses 2% by $630, netting a loss equal to the house edge (5.26%). The system does not beat negative EV; it just concentrates losses into rare catastrophic nights.
