Still not usefull, but now i change strategy

Now iI go for a new algorithm. When there are no progress I will
find 2 empty fields in the same row and find the possibilities
for those eg. fields 2 and 5 can both bee 6 and 9.Then i will try
6->[2], 9->[5] if that's not ok then 9-[2], 6>[5]

I think this must work

Now it solve all 6, but with help from 4 Human Guess!

Still not usefull.

Will try to uptimize performance.
