Perhaps if you tried it with paper instead...#2: Joe (infrapinklizzard) on Dec 13, 2019 [HINT]
This is not "much guessing". There is only one bit of advanced logic needed:#3: Web Paint-By-Number Robot (webpbn) on Dec 13, 2019
After LL
EL 4 r17 limits it to [c3-7] so r17c4 must be black
LL to finish.
Found to have a unique solution by infrapinklizzard.#4: Web Paint-By-Number Robot (webpbn) on Dec 13, 2019
Found to be solvable with moderate lookahead by infrapinklizzard.#5: Michael A Rodgers (marodgers) on Jul 22, 2020 [SPOILER]
Maybe a bird or a chick?#6: BlackCat (BlackCat) on Aug 29, 2020
Very odd.#7: Andrew Schultz (blurglecruncheon) on Dec 16, 2022 [HINT]
Yes, this looks like an origami bird from what I remember. Mine came out more crumpled.#8: Joe (infrapinklizzard) on Dec 16, 2022 [HINT]
But I'm wondering if any moderate lookahead is needed. Joe's logic works right. But after the hints give out (14%) there were a bunch of 1's to fill in.
Then with 57% the hints gave nothing but R5C14 was a dot.
It's a bit tricky but I rechecked and got through with just line logic twice. I'd rather punt & make sure I'm not seeing things before changing the solvability.
You are correct. r5c14 is the key to a LL solve.
(the black pixel at r5c16 must be either the 2 or the rightmost 1 in that line. Either way, r5c14 must be white)
