(Published on 18. July 2024, 14:13 by sujoyku)
The puzzle combines killer and arrow logic and should have a difficulty of approximately 1.5 stars. I wish you happy solving!
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Diagonal: On the negative main diagonal digits do not repeat.
- Killer cages: Digits in a cage must sum to the clue in the top left.
- Arrows: Digits on an arrow sum to the digit in the circle from which the arrow emerges.
Here you can solve the puzzle online:
Solution code: Row 9 from left to right (9 digits in total)
