Knights & Knaves
(Eingestellt am 23. Oktober 2022, 12:00 Uhr von ndsurgenor)
- Normal sudoku rules apply
- Anti-knight: Cells separated by a knight's move (as in chess) cannot contain the same digit
- Region Sums: Digit(s) on a line sum to the same total in each 3x3 box that the line passes through
- 'Knaves': in each column, row and 3x3 box there is a single cell whose value, for the purposes of the region-sum lines, is equal to zero; these nine cells contain a full set of the digits 1-9 and are also restricted by the anti-knight rule i.e. none of these particular 'zero digits' may be placed a knight's move away from any other. Note that one of these 'knaves' has already been included in the grid i.e. one of the 7s

This was incredibly fun. At first glance I thought it might be too difficult, but after some time thinking about how the logic would work I was able to get a foothold and it flowed very nicely throughout. There were several moments with deductions that felt very clever. I enjoyed it a lot.

I spent parts of multiple days banging this one out, making little mistakes, thinking I was never gonna get it. But gosh that was so satisfying to finish it. Very nice

This puzzle was so incredibly fun. One of my favorites in recent memory. It took me a few attempts because I was repeatedly making a silly mistake with respect to Knave placement. Great work!
REPLY: Wow, this is so good to read. Many thanks for taking the time to look at it! - nds
