Normal Sudoku rules apply: Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.
Normal killer cage rules apply: digits in cages cannot repeat and must sum to the number shown in the upper left corner of the cage.
Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits on two-cell lines cannot be from the same residue set. Digits may repeat on a line if allowed by other rules.
