some feedback on a difficult Killer Sudoku
Only just now noticed quite a few helpful replies to a puzzle I posted a while ago:

https://www.reddit.com/r/puzzles/commen ... _solvable/

Near the top a link to this Killer Sudoku combinations page: https://brainbashers.com/combinations.asp
(note that it's not valid for Calcudoku, because there can be duplicate numbers in non-straight cages)

Re: some feedback on a difficult Killer Sudoku
Has anyone found a similar combination listing for Calcudoku as the brainbashers link above ? I saw a youtube video on solving Calcudoku's ages ago & the uploader had a combination sheet he used but I haven't seen anything like it & you never saw the whole sheet to copy it out.

It is a very difficult puzzle, it took me a long time to solve it. I only used analysis and no guessing.

I would like to see more difficult Killer Sudoku puzzles, the Friday Killer is my favourite puzzle of the week.

I had another look, and found that I had made hard work of solving the puzzle, it is not as difficult as I had thought. I missed seeing something that would have made it much quicker to solve. I would still say that it is difficult, and an interesting puzzle.
