With an increase on loss, every extra loss multiplies the next bet. The base bet decides how many losses your balance absorbs before the next bet is bigger than what you have left.
A quick example
Balance $100, base bet $0.10, increase 100%: you survive 9 losses. The 10th bet would be $51.20. Halve the base bet and you survive one more loss.
Rule of thumb
Pick the streak you want to survive first, then work back to the base bet. Our free loss streak calculator does this math for you.
