In addition to Lilningirl's hints, the 3 in row 1 starts in column 5. once these have been worked out the rest can be done with logic and a lot of patience.
This guy is a total moron. He actually says in the description he tested it and found it illogical since he had to use temps on hes own creation and still published it. All puzzles are theoretically solvable using temps. It's just trial and error. That doesn't make it logical. 5 in column 24 goes from row 16-20. Hope that helps some more. Thx for the above hints though.
How sad no one taught Alesko how to get his point across in a kind way. I was taught that 1 unique solution means a puzzle is logical, even if you have to use temps. Show me you have 2 different solutions. BTW, I did not say I found my puzzle illogical.
No, you can't solve all puzzles using temps! Perfectly logical as far as I am concerned because it has a unique solution. Temporaries are a convenience to ease things that can be done mentally if you have the capacity.
