it's food o'clock

(Published on 11. December 2025, 00:00 by aqjhs)

For Leon the cat it is always food o'clock somewhere.
  • Normal sudoku rules apply.
  • Someone just had lunch and left some crumbs all over the grid, and now Leon the cat is looking for them:
    • Leon (r5c4) must visit every box exactly once and end his search on the empty plate (r5c2). (Leon's starting position counts as his visit to box 5)
    • Leon jumps around the grid in chess knight moves knocking down the value of any cell he touches, making it zero (0).
    • All the cells Leon touches have different digits.
  • A clue outside the grid is the sum of the values of the first X cells in the corresponding row/column, where X is the value of the cell nearest to the clue.

For a few moments I thought the solution code didn't work but it was me being dumb! Great puzzle though, it's very well put together and I enjoy the cat theme :)
