The objective of Sudoku is to fill the 9x9 grid with digits from 1 to 9. Each row, column, and 3x3 subgrid (also called a "box") must contain every digit from 1 to 9 exactly once. The game starts with some numbers already placed on the grid, and it’s your job to figure out the remaining numbers based on logical deduction.

To solve the puzzle, follow these steps:

Start by Scanning the Grid:
Look at the numbers already placed on the grid. Focus on rows, columns, or subgrids that are nearly complete. These areas provide clues about where specific numbers must go, helping you start the process.

Use Logic to Eliminate Numbers:
Each empty cell must be filled with a number between 1 and 9, and you can use the numbers already present in the row, column, and subgrid to rule out certain possibilities. For example, if the number 5 is already in a row, it can’t appear again in that row.

Fill in Definite Numbers:
Once you've eliminated possibilities, find cells where only one number fits. These are known as "naked singles," and they’re guaranteed to be correct.

Use Notes for Potential Numbers:
In more complex puzzles, use the note feature to write down all possible numbers for a cell. As you progress, you’ll be able to narrow down the options and solve the puzzle step by step.

Work Through the Puzzle Systematically:
As you fill in more numbers, revisit sections of the grid where you were previously unsure. The more numbers you place, the easier it becomes to complete other sections.

Check for Mistakes:
Use the error-checking feature to ensure you haven't made any mistakes along the way. This helps prevent confusion and allows you to adjust your strategy if needed.

Complete the Puzzle:
Once you've filled every cell correctly, the puzzle is solved! You’ll get a satisfying notification and see how quickly you completed the puzzle if you’re using the timer.

By following these steps and using logical reasoning, you'll improve your skills and solve puzzles faster over time. Sudoku provides endless hours of entertainment and mental stimulation, making it a perfect game for all ages. Whether you're a beginner learning the ropes or an expert seeking a challenge, Sudoku offers a rewarding and intellectually engaging experience.
