Arrow Sudoku: Rules, Examples & Strategy
Arrow Sudoku adds arithmetic to standard Sudoku. Each cage has a circled number — digits must sum to it.
Rules
- Standard Sudoku rules apply: rows, columns, 3x3 boxes have digits 1-9 once.
- Each cage has a circled cell. Digits in cage sum to circled number.
- Repeats allowed in cages (unlike Killer Sudoku).
Strategy
1) Small sums first
Circled numbers 1-4 have few combinations.
2) Use row/column constraints
Row/column rules are primary elimination tool.
3) Forced cages
When row has 8 digits, remaining cage cell is forced.
