excellent exercise in smile logic!

That it is!

Found to be solvable with moderate lookahead by gator.

I wish I could say it was just smile logic, but that is a leap too far.

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.

I enjoyed the extended smile logic and the symmetry of the logic, without the solution being *fully* symmetric. Well done.
