This one is not solvable with logic. It definitely requires guessing.

I was able to get a fair portion with edge logic, including 9 of the 11 in the top row and a few others squares, but then got completely stuck. I was able to make a few "logical assumptions" that let me solve it.

Stinks. Impossible!

Agreed with 1-3: Guessing is necessary.

Found to have a unique solution by Gator.

Like Adam, I did edge logic for awhile, then got stuck on the right side. With very heavy concentration, I was able to think ahead about 5 steps to rule out a move, and then was able to feel sure about the alternative. But thinking ahead THAT far is not practical. It hurt my brain. My logic is done for the rest of the day. Now I can only use my illogical intuition. :-)

Intuition is logical! It's just free of having to be conscious of every step ("unconscious cognition"). On this one, the "guessing" I used would probably be properly termed induction—I guessed there were pixels where the design implied they would probably be. To me, "logic alone" means using only deduction.

Induction probably is easier to use with intuition than deduction, though.

That analysis does not seem like something that should come from an NP like me. Hm.

You don't need any guessing when you know, in which language the title is and what does it mean :)
