With each loss, go up 10% rounded to the nearest non-zero bet unit, with
each win go down 10%. After you break even, then with each extra win,
return halfway back to the lowest bet.
This is identical to D’Alembert except that if you hit $20, you then
go up and down $2. If you hit $30, you then go up and down $3. Etc. Be
sure to keep track of your total since the last time you saw $1, and
reduce bets by 50% after each win that causes a total net win or that
breaks even.
The Ten Percent Solution is for D’Alembert players who never want to
give up, or for “cancellation” players who want to go the limit with
slightly less insanity. With the Ten Percent Solution, the higher you
play the more you might win-instead of being doomed to play higher and
higher with less and less hope or reason.
The Ten Percent Solution can be efficient. Be warned however that this
is not a low risk strategy. It is only “lower-risk play for high risk
players.” The Ten Percent Solution is not for those who lack
discipline.
