Just a few numbers would help out quite a bit. I've gotten this far. I can't really think of anything else logical except guessing. Am I missing something blatantly obvious?

Thanks

Hi Studville.

Welcome to this forum. Tip: you have a naked pair in box 5 that allows some eliminations in column 5 and in .... Good luck.

Well focusing in on box 5... I know rows 4 & 6 have to be either a 2 or 3. But afterwards, I try to figure out the rest of column 5 and it leads me in a circular logic.

hi studville,

it's called box-line interaction -

what are the possibilities for r3c5 ?
( after eliminating 2 and 3 which must be in c5 of box 5 )

Carcul and Pat,

You are my saviours. Whenever I get stumped... I tend make things harder than they should be... I totally didn't think about "scanning" across row 3 (only possibility being 7). Thanks a lot. I look forward to learning more techniques from here in the future -- I'm hooked.
