Double Negative
(Published on 30. September 2025, 02:27 by mathpesto)
Rules:
Normal sudoku rules apply.
Negators: There is exactly one "negator" cell in each row, column, and box. Digits in a negator cell have their opposite value (e.g. 2 becomes negative 2). Each digit is negated exactly once.
Double Arrows: Values on a line must have the same sum as the sum of the circles' values on the line's ends. For clarity, each line is a different color and thickness.

Beautiful! Hard to say anything about it without giving away too much, so I leave it with that. Thank you
