I think it is hard, but my difficulty score is only 29!
I have resorted to green and it is still looking tough.
yes, I am doing my partial greens and still getting nothin'.
It would help if I could fill in the green numbers correctly.
yes, I have had that problem more than once.
There's a bottom left number that opens up a lot ..
Is it a number in the range from 1 to 9?
gee, I hope so
It is ..
I like to think outside the box.
Think in the center column ..
And that was it ..
This is just too much green. I'm starting over.
well, that didn't really help
My difficulty score program agrees that this should be ranked "Hard", but I am going to resort to "Expert" techniques to solve this one.
I think I'm going to have to resort to plugging and hoping for the best. :-) Or maybe I'll go get a snack & then see if I can think any better.
Where do you find the difficulty rankings, and where do you find the techniques to solve? I have been solving fairly steadily using greens
drwho comes up with them. you can click on his profile & find a link.
"them" being the difficulty score. not sure where the techniques are.
There are some explanations of techniques at my web site too. The only expert technique I have explained there is the Alternating Inference Chain technique. In theory you shouldn't need it for this puzzle.
Good grief, that was ugly. I think I had to use 3 check points. I must have a different style of play not conducive to that one, because I thought it was much worse than the experts and super-hard mediums.
I think there is a hidden triple that I overlooked that is the key to the whole thing.
There is a fairly obvious hidden pair I missed, but that doesn't break things open by itself.
Actually, the hidden pair does break things open in an indirect way! There was also a hidden triple that I did see, but that wasn't much help in solving this one.
terminate.. no greens
that hurt the brain cells a bit
slowly but surely ...
done with lots of greens
how do you decide if something is a fairly obvious hidden pair or a fairly shy naked pair?
