What is Naked Pair Sudoku?
Naked Pair Sudoku is a type of Sudoku puzzle where two numbers are placed in a single cell, and these two numbers cannot appear in any other cell within the same row, column, or 3x3 subgrid. The goal is to fill the grid with numbers from 1 to 9, ensuring that each row, column, and subgrid contains all the digits exactly once.
Rules of Naked Pair Sudoku
- Start with the Basics: Just like regular Sudoku, the grid is filled with some numbers. Your task is to fill in the empty cells with the correct numbers.
- Identify Naked Pairs: Look for cells that contain only two numbers. If these two numbers do not appear in any other cell in the same row, column, or subgrid, you've found a Naked Pair.
- Eliminate Possibilities: Once you've identified a Naked Pair, eliminate those two numbers from all other cells in the same row, column, and subgrid.
- Proceed with Other Strategies: Use other Sudoku strategies like Single Candidate, Hidden Pair, and X-Wing to solve the puzzle.
Strategies for Solving Naked Pair Sudoku
- Scan for Naked Pairs: Start by scanning the grid for any Naked Pairs. This can be a quick way to make progress in the puzzle.
- Look for Patterns: Sometimes, you may find more than one Naked Pair in the same row, column, or subgrid. This can be a clue to solve other cells.
- Use Process of Elimination: If you can't find a Naked Pair, use process of elimination to narrow down the possibilities for each cell.
- Stay Organized: Keep track of the numbers you've eliminated from each cell. This will help you avoid making mistakes.
Tips for Success

- Keep an Open Mind: Sometimes, the solution may not be as straightforward as you think. Be open to using different strategies.
