Widely separated tall smile logic to finish.#2: Web Paint-By-Number Robot (webpbn) on Jul 23, 2013
(the 17s in c31,32, 34,35 vs the 1|1s in r1-2 and the 3s in r18-19)
Found to be solvable with moderate lookahead by infrapinklizzard.#3: BlackCat (BlackCat) on Aug 12, 2017 [HINT]
Easy solve. Nice image. No need to look ahead or use smile logic. Just start with the longest number and build from there.#4: Joe (infrapinklizzard) on Aug 14, 2017 [HINT]
No, there is very definitely advanced logic needed. It is smile logic, a specific kind of edge logic. And it is at the end (as I stated), when there are still four long numbers that are all the same (17), so your comment makes no sense.
