The Martingale wins small on most sessions and loses big on the rest. The average result stays negative because the house edge never changes — the progression only moves risk into a fat tail.
The Martingale doubles your stake after every loss so that one win recovers all prior losses plus one unit. It wins small amounts most of the time, which makes it feel unbeatable — until a losing streak arrives.
Run a session and watch the bet size climb: 1, 2, 4, 8, 16… A run of six or seven losses pushes the next bet past the table limit or your bankroll, and a single bad session erases every earlier gain. The house edge never changed.
FAQ
- Does the Martingale system work?
- Not in the long run. It trades many small wins for rare catastrophic losses, and table limits guarantee you eventually can't place the bet needed to recover.
- How many losses in a row does it take to bust?
- From a £1 base with a £250 table limit, eight consecutive losses ends the progression. On even-money bets that happens roughly once every 250 sessions.
- Does it change the house edge?
- No. Every individual bet carries the same edge; the progression only reshapes the distribution of outcomes.
