Interior X-sums (fog)
(Published on 23. January 2025, 22:46 by Fenners)
This may be a new ruleset or it may have been implemented before. It is essentially just X sums but instead the sum is inside the grid and the arrows indicate the directions. Enjoy!
..........................................................
Puzzle: Interior X-sums (fog)
Rules:
Normal 9x9 Sudoku rules apply.
Fog: The grid is covered in fog. Placing a correct digit will clear the fog around that cell. No guessing required.
X-sum Boxes: The digit(s) in a box is the value of the sum of the first X digits in the direction of the arrow where X is the digit in the cell the arrow points to. Two cell wide boxes represent a 2 digit number read from left to right. Digits cannot repeat along an X sum, not even on a diagonal. The arrow always points to an adjacent cell.
Solution code: Column 7 top to bottom no spaces:

I liked this one a lot. Forgot about the non-repeating rule, though.

The fog made this much more approachable, and I really enjoyed the 2-digit clues adding a bit of variety to the sums.

Fun puzzle, thank you! Remembering digits not repeating in diagonal is required at the very end.
