Sudoku is a classic puzzle game that has been around for a long time. It's one of the most popular games in the world and has been played by millions of people. It's so popular that even Google has made a special version of Sudoku for its own Google Play store.

This is a simple proof of concept to allow me to get to grips with Computer Vision techniques on Android. It's not intended to be used in anger so please don't get annoyed if it doesn't work on your device (but do please feel free to submit a Pull Request if you fix any bugs). It also lacks any error handling so if anything goes wrong / your device doesn't have much memory it will probably just crash. As I said it's a pet project not a commercial app.
