Martingale is the most popular betting strategy in 21, but as Mr Blackjack shows, it includes considerable risk to most players.
For most players, Martingale does not work because they do not have the bankroll required to make this system profitable.
Martingale strategy is only profitable when you have a hefty bankroll to start with and do not mind risking extortionate amounts of money. For most players, this automatically makes Martingale a losing strategy for them.
Martingale requires players risk potentially huge sums of money on the basis they’re “due” to win a hand eventually. This can lead to chasing losses and tilting, so we would not recommend using Martingale to players.
Theoretically Martingale doesn’t fail because the odds of you losing every single hand are so low. However this doesn’t take into account bankroll sizes and bet limits at blackjack tables, which most players do not consider and result in Martingale strategy frequently failing them.
Reverse Martingale sees players increase their bet size when they win, and decrease them when they lose.
If players want a betting strategy, focus on systems that limit your downsides and maximize your winnings when you have the advantage in the game, like 1326 or 212. We always recommend players focus on perfecting their basic strategy and card counting skills over betting strategies though.
You need at least $200 to play Martingale for the lowest stakes blackjack tables, and several thousand for games with higher bet limits. These amounts are based on short sessions with the expectation that you might lose the entire amount if you have a cold streak.
