After the initial line/color logic, simple edge logic on the 7 clue in column 20. And then I'm not sure how to finish it.#3: David Bouldin (dbouldin) on Aug 2, 2012 [HINT]
David - what is the next advance step?
C13R16 and C15R16 can't both be black, so C11R16 has to be black.#4: Tom O'Connell (sensei69) on Aug 2, 2012 [HINT]
why can't both be black, David?#5: David Bouldin (dbouldin) on Aug 2, 2012 [HINT]
they would violate R20.#6: Kurt Kowalczyk (bahabro) on Aug 2, 2012
you can look at it from R20 as two-way logic with dots if you'd prefer.
yep, david's right, and it's completely solvable by logic. I scratched my head for close to 15 mins before seeing it. good puzzle, david!#7: Web Paint-By-Number Robot (webpbn) on Aug 2, 2012
