Sudoku Station is an original way to play Sudoku. An integrated help system allows you to request logical hints that become progressively more complicated as the game progresses. This software allows anyone from beginners to professionals to learn techniques for beating any Sudoku game. Sudoku Station also allows you to add games from outside sources where they can be "analyzed" for difficulty (or impossibility) and solved together with the user and machine. With the help system, the software can walk a user through any game, pointing out deductions or possibilities they have missed.
