Found to be solvable with moderate lookahead by gator.#4: Gator (gator) on Apr 26, 2017 [HINT]
I wish I could say it was just smile logic, but that is a leap too far.#5: Susan (Susan) on Jun 20, 2017 [HINT]
After the line logic, consider R2C4 to be black. This makes R1C4 and R2C3 dots. But R1C3 would have to be black making row 1 invalid. So R2C4 is a dot. LL
Now do the same logic above with R6C4, and you will see this is also a dot. LL to finish.
Nice puzzle.
I just took it that it was symmetrical, that got me there with very little logic at all. Of course, that assumption might not have been accurate.#6: Andrew Schultz (blurglecruncheon) on May 15, 2021 [HINT]
I enjoyed the extended smile logic and the symmetry of the logic, without the solution being *fully* symmetric. Well done.
