Sudoku Hero solves sudoku puzzles of all sizes and difficulty. The puzzles may be loaded and saved via text files (.txt).

While Sudoku Hero is a sudoku solving application, it has been built as a way to explore a couple software design patterns as well as PyQt.

• Python 3.4
• PyQt5
• NumPy

• GUI code has been separated from the data models and underlying algorithms.

• A template method pattern is used to encapsulate the sudoku solving algorithm. Two variations of the solving algorithm are implemented in separate classes. Both classes use the same set of steps to solve a puzzle. The sequnce of steps for the solving algorithm is defined and implemented in the base class.

• A factory pattern is used to select an appropriate algorithm for loading a puzzle file based on whether the text file contains DOS or UNIX style line endings.

• A simple strategy pattern is also used to allow the user to switch between two different ways to save a map.
