Ruud has certainly ramped up the difficulty level this week. 20 steps so far and very little progress. This one may well take all week - I don't think I'll be attempting Ruud's promised V2!

I hope not! How are you getting on?Cathy wrote:This one may well take all week
27 "Cathy" steps are normally equivalent to 50 of anyone else's, so it sounds like you've almost made it!CathyW wrote:27 steps now but not much further on.
Thanks Mike! Time to enter all candidates on my grid then so I can chip away at them.mhparker wrote:Hope I've motivated you a bit there!
Mike forgot to add it was so narrow that only he and Cathy could find it. Me and Para had to claw up a rock cliff around N9. Was a really tough, fun challenge. Thanks Ruud.mhparker wrote:This V1 wasn't too bad. There was quite a narrow solving path at the beginning, .

Not me I'm afraid Cathy. But this is a link about nice loops notation Mike gave me once. About time I studied it.CathyW wrote:Can someone help with AIC notation?
NOTE: no 5 in r6c9. Already went in step 20. Also, can't have repeats on outies of n9: forces that repeated digit into r7c7 since 12(3) sees both outies and the cages from two outies cover the rest of the cage except r7c7.Cathy wrote:28. O-I N9: r6c9 + r9c6 - r7c7 = 0
-> r6c9 + r9c6 = r7c7 -> min 2, max 9
-> r6c9 = (13457), r9c6 = (1..8), r7c7 = (2..9)
I think this should be r7c5.sudokuEd wrote:37c. no 1,5 or 8 in r6c5
