What Is Killer Sudoku?
Killer Sudoku combines the familiar Sudoku grid with cages that require specific totals, adding a layer of arithmetic strategy.
Rules
- Follow every classic Sudoku rule
- Each colored cage displays a sum that its numbers must total
- Numbers inside a cage cannot repeat
- No starting digits — every value is deduced
- Use both logic and arithmetic to solve the grid
Solving Tips
- Start with small totals: Low-sum cages often have only a few number combinations
- Use unique combinations: Some totals can only be built with one set of digits
- Cross-check logic: Combine Sudoku constraints with cage math to eliminate options
- Build step by step: Lock in certain cells and expand your deductions from there
