The act of doubling, at each stake, that which has been lost on the preceding stake; also, the sum so risked; -- metaphorically derived from the bifurcation of the martingale of a harness. Called also Martingale strategy. Such a betting strategy does not change the overall likelihood of winning, but in a short run it increases the probability of winning a small sum, balancing it against an increased probability of losing a large sum.

A betting system in which the player starts with a small wager on an even money game. If he wins he stops playing. If he loses he doubles his bet. If he wins the second bet he walks with a profit of his original wager. If he loses the second bet he doubles his wager again. The player will keep doubling his wager as long as he keeps losing. The ultimate result will either be a net win equal to his original wager or a loss of his entire bankroll. The Martingale is one of the oldest and certainly the most famous betting system. I personally I have seen players using it at Internet casinos numerous times. It is deceptive in the short run because it usually does win. However in the long term it loses, as all betting systems do. The big losses eventually add up to more than all the small wins.

This is a betting system based on 'doubling up'.
