How to Play Sudoku: A Complete Guide

Sudoku is a logic-based number puzzle that exercises your brain and improves concentration. Perfect for kids, seniors, and anyone who loves a good mental challenge!

The Basic Rules:

• The Grid: A Sudoku puzzle consists of a grid divided into rows, columns, and boxes. Common sizes are 4×4, 6×6, and the classic 9×9.
• Fill Every Cell: Each empty cell must be filled with a number from 1 to the grid size (e.g., 1-9 for a 9×9 puzzle).
• No Repeats: Each row, column, and box must contain every number exactly once.

Step-by-Step Strategy:

1. Start with Easy Cells: Look for rows, columns, or boxes that already have many numbers filled in. It's easier to figure out what's missing.
2. Use Process of Elimination: For each empty cell, check what numbers are already used in its row, column, and box. The remaining numbers are your options.
3. Look for Singles: If a cell has only one possible number, fill it in! This is called a "naked single."
4. Check Boxes First: Sometimes a number can only go in one place within a box, even if the row and column have other options.
5. Don't Guess: Every Sudoku puzzle has a logical solution. If you're stuck, take a break and come back with fresh eyes.
