(Published on 6. March 2025, 18:03 by EPH)
by EPH ( ephsudoku@yahoo.com )
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Killer cages: digits must not repeat within a cage, and must sum to the value in the corner of the cage.
Arrow: digits along an arrow must sum to the value in the attached circle.
Modularity/Parity lines: the teal lines act as modularity lines: each group of three adjacent cells along a line must contain a digit from (1,4,7), a digit from (2,5,8), and a digit from (3.6.9). In addition, digits along a teal line must alternate between even and odd digits.
Solution code: Enter row 2.
