The Martingale system first came into prominence back in the 18th century, with people using it as a strategy to make a profit from casino games like roulette. The theory behind it is simple, requiring you to double your stake after any losing bet and repeating this up to the point you back a winner. In order for the mathematics to work, each wager must be a single bet at odds of Evens or greater to ensure that you will eventually make a profit. For example, the Championship in England regularly produces drawn matches throughout the course of the season. Odds for draws are usually 2/1 or higher, meaning you will eventually make a profit if you adhere faithfully to the Martingale system.
