I am not a mathematician, so please correct me if I am wrong. It seems that the probability of winning twice in a row (in two spins) on one Double Street (Six Line, Sechser-Transversale) is almost similar to that of winning immidiately on one single number. 1/37 = 0.02702702702.
(6/37)^2 = 0.02629656683.
The difference is just 0.00073046019!!!!
It should be obvious that the two steps on DS give us many opportunities. Right after the first hit we don´t have to risk everything. We may choose be bet 1, 2, 3, 4, 5 or six chips right after the first hit.
There is, however, another difference (there is nothing like stating the obvious): It takes TWO spins (or more). I am painfully aware of the TIME factor. Visiting my favourite B&M Casino in my country only allows me to see approx. 120 spins (I´ve got a train to catch). I am sure that 120 spins
might not be sufficient. Next month, however, I am going to visit a Casino in Hamburg. I´ll be able
to see approx. 160 or more spins per visit.
So I have chosen to look at this number and TWO independent Double Streets (chosen at random).
My goal is to win twice in a row on one of these within 160 spins.
