Equal Sum Zippers

(Published on 30. January 2024, 21:39 by blackjackfitz)

Equal Sum Zippers


Rules:
  • Normal sudoku rules apply.
  • Zipper: Digits which are an equal distance from the center of a lavender 'zipper' line have the same sum. For odd length lines, that sum is also the central digit.
  • Equal Sum Zippers: The sum of all of the digits on a lavender line is the same on every line.
  • Kropki: Digits separated by a white 'kropki' dot have consecutive values.
  • Negator: Place 9 'negator' cells in the grid so that there is exactly one in every row, column and 3x3 box. Different negator cells CAN contain the same digit. For the purposes of the zipper lines and the kropki dots, the value of a negator cell is equal to -1 times the digit it contains.

Play with Sudokupad

Despite the inclusion of negator cells I think this puzzle should be fairly approachable. I hope you like it, if you do please let me know in the comments.

Lovely indeed! And helped a lot to reread the rules and realize it was the lines that shared the sum; not that each had the same zipper value :)

Lovely, very elegant setting! Didn't look like there would be enough clues, but really like how it all unfolded
