1. Difficulty Levels:
Whether you're a beginner or a Sudoku master, Basic Master Sudoku offers three distinct difficulty levels to suit every player:

Easy: Perfect for beginners, offering more pre-filled cells to provide a smooth learning experience.
Medium: A moderate challenge with fewer pre-filled cells, ideal for casual players.
Hard: Designed for experienced players looking for a brain workout.
Note: If you originally intended to have four levels, but the app only includes three, you should update this section to reflect the accurate number. If there are indeed four levels, add the fourth (e.g., Expert: A level for true Sudoku masters with minimal clues and maximum challenge).

4. Educational Value:
Sudoku is a popular tool for sharpening number recognition and cognitive skills in both children and adults.

5. How to Play Basic Master Sudoku:
Grid and Numbers:
The 9x9 grid is divided into nine smaller 3x3 grids. Each row, column, and 3x3 grid must contain the numbers 1 to 9, with no duplicates.

Starting the Puzzle:
Some cells are pre-filled with numbers. Your task is to fill in the remaining cells.

Notes and Pencil Marks:
Not sure of a number? Use the note feature to mark possible numbers for each cell, helping you narrow down options and visualize potential solutions.

Solving Strategy:
Start by scanning the grid for rows, columns, or 3x3 grids with fewer empty cells. Look for missing numbers and logically deduce their placement. As you fill in more numbers, solving the puzzle becomes progressively easier. If you make a mistake, don’t worry—the undo button is there to help!
