Starburst
- Killer cages
- Modular lines
The brief
- Normal Sudoku rules apply.
- Digits in cages must sum to the number in the top left corner of the cage. Digits may not repeat within cages.
- Any set of three sequential cells along a teal Modular 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 may repeat on a line if allowed by other rules.
