I've never been a Roulette player but a friend was talking about the Martingale strategy. You bet totally on red or black and after you lose you double the bet until you win. The whole thing based on your color will eventually come up and you will win your original bet amount. Did some research and the odds of the same color coming up 5 times in a row is 2.4% I know this strategy is used in Blackjack, but was wondering if anyone has had any luck with this strategy in roulette. Thanks in advance!
