I set Payout Multiplier on 9 which corresponds to 11% Win Chance. Then I start betting with less than 1% of my balance and I double the bet amount every fifth bet or in other words every time after four consecutive losses.
This is almost same as mine. But my win chance percentage is 50%, I set 5% increase on both win/lose result. I just stop the auto roll once i hit 7-10 win streak, But my strategy is not working at all times. I set this strategy once i hit 6 lose streak first in manual mode so that the longest win streak has a high chance to hit on following roll.
