The martingale system is a doubling up strategy primarily used on Roulette but you could also use it in other games a little more loosely like Blackjack. The concept is simple, you start with a single bet and if it loses you then place the bet again but double the stake. You carry on doubling your stakes to you win and then you revert back to the single bet and start the sequence again from the beginning. Each time you win you have made a single bet win.
