Jolly Jumper (Anti-knight killer sudoku)

(Published on 15. May 2024, 23:19 by sujoyku)

Since it is my goal to set some puzzles for next year’s DSM 2025, I recently have worked on some “easier” puzzle types that could be suitable for a competitive situation. Nevertheless, I thought I should share another puzzle with you. This one is a killer sudoku with anti-knight constraint whose difficulty could be slightly above 2 stars. Please feel free to share in the comments how you like the puzzle. I wish you joyful solving!

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Anti-knight: Cells a knight’s move (in chess) apart may not contain identical digits.

- Killer cages: Digits in a cage sum to the clue in the top left.

Here you can solve the puzzle online:

Solve on CtC

Solution code: Row 5 from left to right (9 digits in total)

Thank you for your kind comments! I am glad that you liked the puzzle and found the difficulty rating to be more or less accurate. @moHa: I think I know what part of the solve you are referring to. There is some deduction that is not entirely easy to spot.
Kind regards, sujoyku
