Very nice!#3: Kristen Vognild (kristen) on Dec 16, 2018 [SPOILER]
It's hard to get an elegant spiral in square blocks, but I knew exactly what this was!#4: Norma Dee (norm0908) on Dec 16, 2018
Interesting.#5: Brian Howard (oduck83) on Dec 16, 2018 [HINT]
I needed a tiny bit of edge logic myself, in c1 and r40; I would be interested to hear if it is possible to do with only line logic.#6: Aurelian Ginkgo (AurelianGinkgo) on Dec 16, 2018
Very cool.#7: Joe (infrapinklizzard) on Dec 16, 2018 [HINT]
After purple logic (hints from the Hint button's purple arrow)#8: Brian Howard (oduck83) on Dec 17, 2018 [HINT]
Line Logic c2r33 = black (must be part of a 3)
Line logic c2r34 = White (the end of the 3)
Purple logic
Line logic r29c8 = black (must be part of a 3)
Line logic r29c7 = White (the end of the 3)
Purple logic to finish
Thanks, Joe -- it's obvious now. I forgot that the helper isn't clever about repeated clues (if something is a 3 or a 3, it doesn't realize that it's a 3...).
