This app leverages backtracking to solve Sudoku puzzles and provides a seamless user experience through the use of Android fragments. The Sudoku grid is managed using an efficient 4D array structure to represent the entire 9x9 grid as 3x3 sub-grids as 3x3x3x3.\n\n## Main Sections\n\n- New Game: Start a fresh Sudoku puzzle.\n\n- Continue Game: Resume your previous game where you left off.\n\n- Backtracking Visualization: Visualize the solving process using multithreading for a smooth experience.\n\n- Victory Page: Celebrate your success with a dedicated victory screen upon completing the puzzle.\n\n## Additional Features\n- Time Counter: Tracks the duration of the game.\n- Hint System: Provides hints to help solve the puzzle.\n- Remaining Digits Tracker: Shows how many numbers are left to complete the grid.\n- Score Calculation: Keeps track of your performance based on time and accuracy.\n- Penalty System: Adds penalties for incorrect moves.\n- Difficulty Levels: Choose from Easy, Medium, or Hard levels to suit your skill.\n\n## Technical Details\n\n- Language: Java\n\n- IDE: Android Studio\n\n- Algorithm: Backtracking algorithm for solving Sudoku puzzles.\n\n- UI: Utilizes fragments to create a dynamic and modular interface.\n\n- Data Structure: Uses a 4D array (3x3x3x3) to efficiently manage the entire Sudoku grid.\n\n## How It Works\n\n### Backtracking Algorithm\n\nThe core of the Sudoku solver is a backtracking algorithm. It systematically searches for the correct numbers to place in each cell, ensuring that the Sudoku rules are followed:\n- Each row must have numbers 1 to 9 without repetition.\n- Each column must have numbers 1 to 9 without repetition.\n- Each 3x3 sub-grid must have numbers 1 to 9 without repetition.\n\n### Multithreading for Visualization\n\nThe app uses multithreading to display the backtracking process in real time. This feature provides users with a visual representation of how the algorithm solves the puzzle step-by-step.\n\n## Usage\n1. Launch the App: Open the Sudoku app on your Android device.\n\n2. Select a Mode: Choose between New Game or Continue Game.\n\n3. Set Difficulty: Pick your desired difficulty level.\n\n4. Start Playing: Use hints, track your time, and aim for the highest score!\n\n5. Celebrate Victory: Upon completing the puzzle, enjoy the victory page to mark your achievement.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkhushi130404%2Fsudoku","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkhushi130404%2Fsudoku","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkhushi130404%2Fsudoku/lists"}
