Puzzle #49: Slitherlink; Liars
I'm not sure how much I will post in the next week or so. I will be flying out to Hungary on Sunday to participate in the World Sudoku Championships and World Puzzle Championships.

Took me a couple days and a couple lurches, but I solved it. (After you find the four problem areas in C3-6, prove that R7C3 isn't lying.)
ReplyDeleteSo, how's Puzzle 50 coming along? Is it going to be a doozy?
Solved this one now when revisiting it. Nice one. Towards the end, I liked how the "negative" logic made the solution unique.
ReplyDeleteHi.
ReplyDeleteI've found the four problems in C3-6 as cyrebjr explained, but I can't manage to prove that R7C3 is true.
Can you give me a little hint ?
Thanks anyway !
Power of posting !
DeleteFound an incoherence between the diagonal 3s pattern and the right 0 on row 7.
