Gamezone – Sudoku

🎯 Objective

Fill the 9×9 grid so that every row, column, and each of the nine 3×3 subgrids contains the numbers 1 through 9, without repetition.

📝 How to Play

1. Start with the given clues
   Some numbers are already placed on the grid. These are fixed and cannot be changed.

2. Use logic, not guessing
   Look at empty cells and determine which numbers are missing from that row, column, or 3×3 box.
   
   Place a number only when you are sure it fits without breaking the rules.

3. Apply elimination
   If a number already exists in a row, column, or box, it cannot appear again there.
   
   Narrow possibilities until only one number fits in a spot.

4. Keep track of options
   Write small pencil marks (possible numbers) in cells if you’re unsure.
   Update these as you place more numbers.

✅ Rules Recap

• Each row must have 1–9 without repetition.
• Each column must have 1–9 without repetition.
• Each 3×3 subgrid must have 1–9 without repetition.

💡 Tips for Beginners

• Start with rows, columns, or boxes that are almost complete.
• Always double-check before filling in a number.
• Work systematically (row by row or box by box).
