It would take a little help.

I do not know where to start.

Totally love it. Great challenge but completely do-able. Best puzzle for some time.

You need to work out where the 5 in the final column can't go.

Do-able? Yes, but there are multiple possible solutions, so the end at least is definitly not logical.

Where they leave 12.

It's do-able... It's just not... hm. If you derive pleasure by applying logic to ascertain outcomes, then most of this puzzle is for you. If you also derive pleasure by just trying s**t out to see if it works, than all of this puzzle is for you.

Perfect. Thanks.

Mostly logical. A few ambiguous squares at the end. Thank you for the puzzle!

Solamente los dos últimos tienen dos soluciones, por lo demás, es excelente. Gracias.

Thank You!!

Once you find where the 5 goes in the end column it's logical until the last 2 squares. Difficult, but a lovely image when you do finish. Thanks.

Very good challenge. Most enjoyable. Thanks.

Thanks.

Hint: the 5 in the last column starts in r3. From there just two ambiguous pixels at the end.
