Modular Knights
(Published on 21. January 2025, 19:50 by Jolly Rogers)
RULES:
- Normal Sudoku rules apply.
- Digits along an arrow must sum to the digit in that arrow's circle.
- Also, the digit in an arrow circle must belong to the same modular group [147], [258] or [369], as every cell a single chess knights move away from it.
- For example: if cell r1c1 was an arrow circle, its digit would belong to the same modular group as cells r2c3 and r3c2.
