This roulette strategy lives up to its name coincidence. (Zufall in German language)
The concept follows the idea of overcoming coincidence with coincidence.
Two simple chances are chosen at random
and the stakes get optimized to their difference rate if there are opposing opportunities.
(It would make no sense to put 16 pieces on black and 32 pieces on red at the same time.)
It always starts with 16 pieces per chance.
Then the bet is doubled on one chance and halved on the other.
This goes on as long as the opening balance ( on balance) is not exceeded,
in the event of a balance win, the whole procedure starts again from the beginning.
