Martingale Definition

The martingale system refers to an investor increasing their stake on a new bet each time they lose. The logic is that eventually a bet will win and the money lost will be earned back in addition to winnings.

Example

A prime example of the martingale system in betting could be used with roulette. A punter could place a bet on red and each time it loses, he or she doubles the bet so that when it finally wins the money is made back.
