• Pygame
• Requests library

Installation

1. Clone this repository:

   git clone https://github.com/choppystick/PyDoku.git
   cd sudoku-game
   

2. Create a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows, use `venv\Scripts\activate`
   

3. Install the required packages:

   pip install -r requirements.txt
   

4. Run the game:

   python main.py
   

How to Play

1. Launch the game by running main.py.
2. In the main menu, you can choose to:
   • Play a randomly generated Sudoku puzzle
   • Play a puzzle from the New York Times (with difficulty selection)
   • Exit the game
3. During gameplay:
   • Click on a cell to select it
   • Use number keys (1-9) to input a number into the selected cell
   • Press ESC to return to the main menu
4. The game will automatically validate your solution when the board is filled.

Project Structure

The project is structured into several Python classes:

• SudokuBoard: Represents the Sudoku board and handles puzzle generation and validation
• SudokuGame: Manages the game state and user interactions
• SudokuRenderer: Handles the drawing of the Sudoku board on the screen
• Menu: Manages the main menu and NYT difficulty selection menu
• GameController: Orchestrates the overall game flow
