NOT Logical. SO VERY not logical. I found at LEAST half a dozen different possible solutions. Even assuming symmetry, there's more than one solution. Whenever you have mirrored diagonals of isolated pixels like at the nose-cone of this puzzle, it is automatically NOT logical.
It's fairly easy to guess what the correct solution is, but the puzzle is not, technically, logical.
Gah! Extremly easy when making assumptions, extremly hard and with more than one solution when sticking to logic - puzzles like these are the worst! Sorry, but this is really annoying to me, especially when puzzles like this one are so easily made logically solvable (and usually extremly easy) when inverted!
Well.. I enjoyed it - I'm starting studies in a couple of months = I dream of becoming a therapist - I see that there is a wealth of potential clients out there. Chill pill time guys - this is a games / entertainment site - stress of any kind should not enter into it. AND my husband thinks I'M highly strung.....LOL :):):)
