4 Lonely Knights
(Published on 6. October 2025, 11:50 by billybeth)
Any two cells who have the same digit and are living a chess knight's move away from each other are happily married. A cell with no pair a chess knight's move away is single. A cell who sees more than one of the same digit a chess knight move away is living in sin as are their partners. The even digits are all happily married apart from four singles and never sin!
On the yellow line no digit can be consecutive with any other digit on that line.
Numbers show the sum of the digits on the indicated diagonal.
Solve online:Sudokupad.
Solution code: How many of the odd digits are living in sin starting with 1 then 3, 5, 7 and 9 (answer should be a five digit number)

It's been 15 minutes since I solved the puzzle and trying to figure out how I'm getting the solution code wrong. Disappointed since the puzzle itself was a lot of fun to solve.
EDIT: Okay, the solution code is definitely wrong. You have miscounted the number of sinners for the digit 5.
