v�The main Features of System of Game In Donald-Natansona Roulette
Under any circumstances put on the red. We will assume that you have originally put 1 dollar. At loss black, increase the rate by unit, and if red - reduce by unit. But what to do to the player who has put dollar on red and won? As considered T.Donald, neither zero, nor negative rates do not happen, therefore the rate should remain invariable. And why? - Mathematician Natanson has thought. Also has tried - it has turned out rather interesting.
Not to recede from canons of initial system, after the rate on red and a prize, the rate needs to be reduced by unit. At the rate in, following it will be equal 0. The zero rate is an admission of the next start of a roulette. But thus you watch closely that will drop out, - that the nobility how to put next time. Let, the red again drops out. You again should reduce the rate as you have won. In that case your subsequent rate is equal-1. The rate on black will be the negative rate on red. Further in game one rule operates only: at loss black the rate increases, at loss red - decreases.
According to T.Donalda's system, at loss zero the following rate should be increased. r�r�s�r�r�s�r�r� has suggested to increase it on the module. In other words, the rate should be lifted on unit if it is positive, and to lower, if it is negative. However, zero prevents to define your income unequivocally.
Let's consider a variant when at loss zero the rate was positive. Then zero it is completely equivalent to the black.
Zero can drop out and at the negative rate. Now it is equivalent to the red.
Loss zero can occur and at the zero rate. Any variant of actions is possible: at rate lifting zero it will be equivalent black, at reduction - red. Remember statistics: if the red dropped out more often, than black, it is necessary to increase the rate if is more rare - on the contrary.
