Also a 679 XY wing pivoted in R3C9 eliminating 7 in R1C2 solves it.

I lost track of the number of XY wings I used to 'clean up' this puzzle before finding the one that cracked it (a 134 pivoted in R6C6). In terms of VH techniques, this was about a 5 stepper for me. I' ...

Ahhhhhhhhhhhhhhhhhhhhhhh.

Thanks Marty

Sorry, I'll try copying the grid again.

I must be missing something here. I saw the first two XY wings mentioned by Clement, which gave me the following grid.

I certainly wasn't complaining. I enjoy a challenging puzzle. It was just that on this occasion, I thought I was blind to the obvious (which often happens!). As it turned out, I was not alone. Phew - ...

I am relieved to read the comments above! I've just solved this one and thought I was making an absolute dog's breakfast of it. As it happened I went down the X wing, XYZ wing, XY wing path - but is w ...

The same naked triple occurs in Box 2 - with the same result.

A five minute puzzle that almost solved itself. Very few unsolved cells after basics, needing a a 246 XY wing to clinch it.

Two steps for me: 258 XYZ wing centred on R8C3 which opens up a 578 XY wing centred on R9C3.

If you start in the top left corner on your search for XY wings, you'll solve it in a flash.

Also a 468 XY wing centred on R1C4 provides a solution. Since after basics this puzzle comprises only 1s, 4s, 6s, and 8s, I suspect that there are several solutions. I'll leave it to others to find th ...

The puzzle for a particular day becomes available according to local time. The time stamps are GMT, I think (or is that called UTC these days?).

Clement, in Tanzania, must do the puzzle shortly aft ...

I just did this puzzle (a little late) and went to the forum expecting to see complaints about how easy it was.

Looking at Keith's 'after basics' grid, there is a one step 158 XY wing pivoted on r9 ...

The shortest day on this side of the globe, and the longest puzzle, for me at least. Look carefully for hidden pairs in this messy puzzle. I missed one and wasted at least 30 minutes searching for 'ad ...

Thanks Marty. The other mistake I made was saying that R6C3 becomes the pincer. It's actually the pivot. Not the computer, not my typing, just a fuzzy brain Confused

(smiley intended!)

That smiley should be '8'. Don't know how that happened; must be the computer, couldn't possibly be my typing skills!

Are you referring to:
r4c3 (A), r4c5 (*), r6c3 (B), r6c6 (C)?
Must the XY Wing (679) removes the common digit '7' from r4c5?

Hi Ema,

You're correct but you're not quite there yet. There i ...

And there's a good ol' XY wing (679) for those of us who, for no particular reason, prefer to avoid uniqueness solutions.

Thanks Wendy. Rolling Eyes
