Batman!

Widely separated tall smile logic to finish.

(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.

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.
