The solver is hosted on: http://oskaerik.pythonanywhere.com/
If you want to run the solver locally:
- Clone the repository
- Install Django
- Run
python manage.py runserver
from a terminal in the root folder - Go to http://localhost:8000/ in your browser
If you enter an invalid grid, it will try to find a solution for 120 seconds or until a contradiction was reached. The solver can find solutions for grids with more than one possible solution as long as it doesn't time out.
Happy solving!
