No hiding place (anti knight arrow Sudoku) - updated and improved
(Published on 19. June 2024, 23:28 by Fool on Hill)
Puzzle rules
This is an updated version of the original puzzle, with an extra clue in box 7. Huge thanks to Niverio for the suggestion which makes the puzzle a whole lot better by taking out the messy (and over-tricky) ending. For the original version, take out the box 7 arrow. Thanks to all who tried it before. Motto: there is no such thing as too much testing ...
Normal Sudoku rules apply.
Digits on an arrow must sum to that arrow's circle. Where arrows cross, each goes straight on.
Cells separated by a knight's move (chess) may not contain the same digit
Here is the SudokuPad link: No hiding place
Solution code: Row 9 - 9 digits, left to right

I started solving yesterday and finally finished the original version today, indeed quite tricky but not too hard. 3 out of 5 difficulty for me without he extra clue.
Thanks for setting, I love knights-moves variants :-)

I see what you mean about the end, it's a bit mean isn't it ^_^. Enjoyed the start a lot!

This puzzle is now rather easier than experienced by the first people who solved it - and I hope much better too.

Cool puzzle. Found it pretty tough going towards the end.
I have added an extra clue now, which smooths that out - thanks so much for the comment. I had missed something and thought it was easier than it was. Thanks for your comment.
