Basic Rules
The Grid
A Sudoku puzzle consists of a 9×9 grid, divided into nine 3×3 boxes. Some cells come pre-filled with numbers.
The Objective
Fill in the empty cells with numbers from 1 to 9, ensuring each number appears exactly once in each:
- Row
- Column
- 3×3 box
Getting Started
Step 1: Scan the Grid
Start by looking for cells where only one number can fit based on the pre-filled numbers in the same row, column, or box.
Step 2: Use Elimination
For each empty cell, list all possible numbers that could go there. Eliminate numbers that already appear in the same row, column, or box.
Step 3: Look for Patterns
Search for patterns like pairs or triplets of numbers that must go in specific cells, helping eliminate possibilities in other cells.
