- Killer cages
- Modular lines
The brief
- Normal sudoku rules apply. - Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage. - Every set of three adjacent cells along a teal modular line contains digits with three different remainders when divided by 3.
