A Sudoku Solver using Python that solves any Sudoku puzzles in 2 seconds (95% of the puzzles are solved within 0.5 sec regardless of the difficulty).
Check out my GUI demo video on Youtube: Click me!
Due to large file restriction, you may NOW download the .exe version of the GUI (everything built in) in my google drive (Anti-virus scan passed)
# with gui
python Sudoku_gui_tkinter.py
# without gui (in terminal)
python Sudoku_solver.py
If you want to use a customized board, either add a line to puzzle1.txt following the nested list format, or add a line to User_data.txt and then use Sudoku_converter.py to convert that puzzle into the puzzle1.txt.
pip install numpy (required)
pip install tkinter or pip install pygame (optional: if you wish to run the GUI)
