RULES:

---

Normal Sudoku rules apply.

• Killer: Digits within a cage must sum to the number in the top-left corner
(digits must not repeat within a cage).
• Parity (red): Digits along a Parity line alternate parity {odd/even}.

---

MODIFIERS:

---

• Negator: There are 9 Negator cells contained within the grid comprised of a set of the digits from 1-to-9. Each row, column and box contains exactly one Negator cell

for Killer values
Negators subtract the value of the digit in that cell from cage totals (instead of adding them).

INTRODUCTION:

---

This was a prompt posted by Scojo for one of his setting weekends and I absolutely loved it. There's something about giving yourself a few restrictions that really gets the creativity flowing. I'd never used Negators, in fact I don't think I've solved a puzzle before with Negators but they lead to some cool logic. I'll definitely be revisiting that constraint in the future. I hope you enjoy.

Have fun!
