Quite a bit of guessing if I'm not mistaken...

Not logical.

Just the last 4 dots but they're obvious.

You can double and triple check all you want, this requires guessing. I was able to complete the puzzle, get an answer that works with the clues but was invalid, therefore you must guess the answer.
That being said, it is a wonderful puzzle. Good job.

Guessing definitely needed, but a nice result. Thanks.

Only the last 4 dots are ambiguous. The rest of the puzzle is logical. Thank you for the puzzle!
