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.
