was worried for a while, but eventually worked an end loose.
must have started out in the right place, because it was totally easy. Only cross hatching needed.
wow, once you get started it's completely easy
yep, pretty easy
looks like an interesting pattern
done.. that felt like it took too long
I like the pattern.
there, did today's and caught up in the archives - it's been a busy week! Have a nice weekend, everyone
It's funny how some days it takes me ages to do an Easy... yet today I managed this one quite quickly!!!
and it's medium!
I've been taking a very long time on this one.
Have a good weekend everyone
And I've made two mistakes.
Finally got it. No greens. Needed pairs. I was savoring being on the top row of the newbies, but it looks like I'll be moving to the bottom of the regulars.
Unique rectangles, conjugate chains, x wings... what a wonderful puzzle for Saturday morning.
yikes! Orange's comments are scaring me.... too early in the morning to conjugate
an x wing solves the conjugate chain (and the puzzle)
neither of which I understand, but that's ok!!!!
Difficulty score 30. I think that is too high. I found it very easy. Only techniques required are cross-hatching and virtual cross-hatching. No X-wings or other exotic strategies required.
Hi Doc, did you need greens? I have 14 filled and I am resisting the urge to go green.
Hmmm, I will keep trying...
Consider the upper right block and the lower left blocks. If you fill in a number in the top row, bottom row or the 1st or 9th columns, they could limit the potential locations of that digit in the 2 blocks to only 2 cells in a row.
Then you can use that fact to do virtual cross-hatching.
I just found a couple of 9s I had missed. Things are moving again.
I think the 9s were the first that I finished.
I could really use another 5
Once you get one 5, you get the rest pretty quickly.
Yes! Done, no greens!
The 4 in the bottom row broke it loose.
interesting looking puzzle. no outside edges
done. not too difficult
I just finished too. No greens!
It's funny to read how everyone else solved it - 9's first and trying to find the 4's and 5's... I had to have solved it in a totally different way.
I found the 2's first.
I did my first sudoku all by myself!!!
a little slow starting, but finished very quickly with no greens. Basic crosshatching didn't work, it needed some deduction -- for me it was the 2s that opened it all up
