About Killer Sudoku
The Killer Sudoku puzzle is like a traditional Sudoku in that every row, column and 3×3 block must contain the numerals 1-9. The difference is that you are not given numbers to start you off. The numbers that occur in the squares linked by a shaded line add up to the total given in the top left-hand corner of each set. No number is repeated in any of these sets. Use these totals to find the right numbers to solve the puzzle.
5 Killer Sudoku Solving Tips & Strategies
Discover the secrets to mastering Killer Sudoku with these 5 solving tips! Whether you’re new to Killer Sudoku or a seasoned solver, these easy-to-follow strategies will help you get started and solve these clever puzzles with confidence.
1. Start with Single Digits:
Fill in single digits where you can see a clear placement.
2. Focus on Two-Digit Sets:
Next, identify two-digit sets and figure out possible combinations. For example, if the total is 3, it can only be 1 & 2. If it’s 17, it must be 9 & 8.
3. Expand to Three and Four-Digit Sets:
Gradually move on to larger sets and continue noting possible numbers.
4. Use the 45 Rule:
It’s important to know that the numbers in each row, column, and 3×3 block add up to 45. As a rule of thumb, if the shaded sets filling a 3 x 3 block have just one digit protruding into another block, that number must be the total of those sets minus 45.
5. Enforce Basic Sudoku Rules:
Always adhere to the fundamental Sudoku rules: no repeating numerals 1-9 in any row, column, 3×3 block, or set of numbers. Following these rules will guide you to unravel the Killer Sudoku!
