I follow the streaks and martingale plus a unit when I play. I like to find single zero video roulette and start at 1 dollar and grind away at a $100 dollar profit. Takes a bout an hour of play.
Single zero so key to those quick video schemes.
Had one in tahoe I ran like 3 different betting schemes and hit streaks every time.
The ROI though, as you start churning over and over. I've bet a lot to win a little or lose a little, and basically earn points...lol. The ultimate grind. They treat those video roulettes like slot machines when it comes to tallying player points. In Lake Tahoe it's +EV.
I also agree, you have to stay low on the dollar amounts or the machine treats you differently. At least that's my experience with literally every piece of software you find in a casino.
I don't use much martingale straight up, using more betting patterns, but either way, it's a progressive betting scheme.
