Plus Minus Sudoku
(Published on 11. April 2021, 11:04 by Arlo Lipof)
Rules:
- Normal Sudoku rules apply.
- The circled cells – where the same colours represent the same digits – form 4 horizontal and 4 vertical equations.
- Killer cages with the same shape are exact clones of one another. The digits in these cages must sum to the small clue in the top left corner.

Love when I need to pull out a piece of paper and do simple algebra to solve a sudoku. Very nice!
A: True: it’s either the right linear combinations or pen and paper. ;-) Thank you!
