Martingale System

The Martingale is a betting strategy where you double your wager after every loss. The logic: when you eventually win, the payout covers all previous losses plus a profit equal to your original bet. Start at $5, lose, bet $10, lose, bet $20, win. You've lost $5 + $10 = $15 and won $20, so you're up $5. Back to the start.

The problem is that losing streaks grow your bet exponentially. After 7 consecutive losses starting at $5, your next bet is $640. After 10 losses, it's $5,120. Table limits exist. Your bankroll has a ceiling. Your courage has a ceiling. And none of these protect you from a 12-loss streak, which is less rare than people think. On European roulette, a 10-loss streak on red/black happens roughly once every 773 sequences.

No betting system can overcome the house edge. The Martingale just rearranges the distribution of results: many small wins punctuated by rare catastrophic losses. Over enough time, the house edge grinds through. Try it in our Martingale Simulator to see exactly how quickly things go wrong.
