How to Get Started – Practical Sudoku Solving Advice

1. Start with Easy Puzzles. Use easy Sudoku to learn basic rules – find hidden singles (a digit that can go in only one cell in a row, column, or block).

2. Master the Pencil Marks. Write possible digits in corners of cells. When you find a number can only be in one cell, fill it in.

3. Use the “Naked Pair” Technique. If two cells in a row/column/block contain exactly the same two candidates, you can eliminate those digits from the rest of the row/column/block.

4. Look for “Hidden Pairs”. When two digits appear only in two cells of a row/column/block, remove other candidates from those cells.

5. Check the “X‑Wing” Pattern. This advanced technique helps eliminate candidates across rows and columns, letting you finish harder puzzles.

6. Practice Killer Sudoku. Start with low cage numbers, then progress to higher sums. Learn to use the “sum” logic: if a cage contains two cells and the sum is 11, the digits must be 2 and 9.

7. For Calcudoku, focus on operators. For a cage with “×” and sum 12, the only pair from 1–9 that multiplies to 12 is 3 and 4.

8. Binary Sudoku Tip. Count zeros and ones as you go; if a row has four zeros, the remaining cells must be ones.
