Sudoku is a number puzzle game played on a 9×9 grid. The grid is divided into 9 smaller 3×3 boxes. The objective is simple:



👉 Fill in the grid so that every row, every column, and every 3×3 box contains the numbers 1 to 9 without repeating any number.

📝 Step-by-Step Guide to Play Sudoku

Step 1: Understand the Grid

  • A Sudoku puzzle starts with some numbers already placed in the grid.

  • Your job is to fill the empty spaces.

  • Rule: Each row, column, and 3×3 box must have 1–9 exactly once.

Step 2: Start with Easy Numbers

  • Look for rows, columns, or boxes where only one number is missing.

  • Fill that number.

Step 3: Use the “Process of Elimination”

  • If a box is missing multiple numbers, check which ones are possible.

  • Eliminate numbers already present in the row, column, and box.

  • Place the correct number when only one option is left.

Step 4: Use Pencil Marks (Candidates)

  • In tough puzzles, write small numbers in the corner of a cell to mark possible options.

  • Example: If a cell can be 2 or 7, write both small.

  • Later, when one is eliminated, you know the answer.

Step 5: Keep Scanning

  • Continuously scan rows, columns, and boxes.

  • With each new number you place, the puzzle becomes easier.

Step 6: Check Your Progress

  • Avoid guessing randomly—it may lead to mistakes.

  • Sudoku is a logic-based game. Every number can be found with reasoning.
