It is not fun start with one units win five times and lose five. The total is a loss.
Some call red plus and black minus and if they win with 1 units on the table they switch color.
I do not know if they reverse the system as well.
I think it is not a very good system as the bets may be low, the bankroll can still decrease heavy.
I am now investigating progressions for EC, and it is not easy to find a good one. I play one now
have done 1815 spins and is up 2571 units on a zero wheel. The basic is to increase the bet slow and parlay.
The longest round was 40 spins. One thing I have seen is the total bets are 10 times the net.
I will try it until 10000 units won or loss of the same. (10000 units equals 100 Euro). I like to test using play.
The reason is a stream of numbers in 1000 or more, will never show up twice. It is combinations of astronomic height, like all atoms in known universe. And only one of them is importent, the stream I face at playing.
Try numbers from a casino, shift one step (start play from the second number), the result can be much different.
