Martingale ( blackjack)




1. One of the oldest betting progressions in existence. It requires a player to double the size of his bet after a loss and to continue doubling his bets until a win is achieved, resulting in a profit equal to the size of the original bet. It is impossible to win in the long run using this system.

2. Often used as a term for any system which requires increasing a bet after a loss. It is not a winning method of betting in any form.
