From the beginning, Sudoku Sensei was intended to become a program with Graphical User Interface. Though, the first versions were just the core of that: a sudoku logic explainer engine. That is, a library capable of solving sudokus just like humans do.
The engine solves sudokus by applying complex logical rules a few times, instead of applying simpler rules (like guessing and backtracking) many many times. These complex logical rules are exactly the same ones that people use with paper and pen.
In the first versions of Sudoku Sensei, the engine is accompanied by several command line demo programs. These illustrate how to use the engine and allow creating, solving and explaining a wide variety of sudoku problems. With Sudoku Sensei 2.0 you will enjoy playing with sudoku boards designed by yourself. You can choose different levels of difficulty and different levels of help. It will allways provide hints with a logical explanation whenever you get stalled.
Like other sudoku games, Sudoku Sensei 2.0 allows you to generate new games or type them in, save and load games, peek at the solution, print the game, undo/redo, and other common features. It includes a Tutorial for playing sudoku, and a Manual for the program usage.
