Done, I should have resisted the greens a little longer...
it was easy after a good night sleep
have a great day everybody
done. no green. slowed down after 18, but missing digit scans finally got it.
Brittle is there any hints at all? hidden pairs that kind of thing?
done... used greens about halfway through
sorry, herinfernallady, working on something else and didn't see your question
here's how i did it: lately i start by wandering the board, filling in what i can in 3x3s that have at least 4 or 5 filled in (mostly cross-hatching); then i might do this again to pick up any newly obvious numbers. The goal is to get low-hanging fruit and easy-up the board a bit. Then i either scan rows and columns for missing numbers, normally limiting this activity to those with at least 5 numbers filled in. Then cross-hatching to get more "gotta-be" numbers. Then do some more of all of the above, since it sometimes snowballs. I look for some naked pairs, which often will tell you what another box or two are. Today i did all that, it went quickly up to 18 filled in, but then i and had to bring the missing digit scans down to rows/cols with 4 numbers filled in. Once i got another one or two it all (slowly) opened up.
no greens, nothing really fancy. just patience.
done with a shopping break in the middle
WOW thank you Brittle im still learning this one
maaaaart's a bunny bear and he's o.k.
he cutes all night and he cutes all day
allo hurshy :)
terminate... no greens
but it took a while to see the naked pair
you know, only in a sudoku grid is it ok to go looking for a naked pair ;)
What a pleasure it was to find that the naked pair wasn't a couple of old men. Done without greens (finally)
done, used a couple of greens to get going, sorry i did that, cause it was a sure breeze after that
Rats. Some mistake.
17. Stuck. Too sleepy to continue now.
Done, no greens. But I had a "guess" in the form of a poorly analyzed unique rectangle.
I don't think I ever came across those naked guys.
