Can roulette be beaten at casinos? I've come download games 88 across the martingale system where you double up on your bets when you lose in order to win back your initial bet back. I know streaks of up to 10 are pretty common so I was thinking of maybe starting betting after there has been a streak of 4 reds or blacks etc and then start doubling on my losses. Occasionally I will come across a streak of 10+ I know but if I lose 6 times, stop at that count that as a loss. Basically hoping that my wins will be more than my occasional big loss, has anyone tried anything like this before, anyone won from it? I play European roulette so single "0" and if you do hit zero you get half your money back.
