Why Start with Easy Sudoku?
Easy Sudoku puzzles have more given numbers, making them perfect for learning the basic solving techniques. You'll quickly gain confidence as you complete each puzzle.
How to Solve
Fill in the grid so each row, column, and 3×3 box contains the numbers 1-9. Start by looking for rows or columns with only a few empty cells.
Benefits of Daily Sudoku
Regular Sudoku practice improves concentration, memory, and logical reasoning. It's a fun way to keep your mind sharp at any age.
The Foundation of 9x9 Solving
Easy 9x9 puzzles typically provide 36 to 45 givens out of 81 cells. The solving path is designed to be linear: each logical step reveals exactly one cell, which in turn makes the next step obvious. The techniques required are limited to Naked Singles (only one number fits in a cell) and Hidden Singles (only one cell in a row, column, or box can hold a specific number). Mastering these two techniques on easy puzzles creates the foundation for all harder difficulties.
Aim for consistent completion rather than speed. When you can solve easy 9x9 puzzles without errors on three consecutive attempts, you are ready for medium difficulty.
