GNOME Sudoku For Linux

GNOME Sudoku is an open source software that provides users with a Sudoku generator and solver game designed from the ground up to be deployed along with the award winning GNOME desktop environment.

Sudoku is a popular Japanese puzzle/logic game. This application, originally created by Thomas Hinkle and not distributed as part of the GNOME Games project, intends to provide users with a simple interface for generating, playing, saving, printing and solving Sudoku puzzles.

Key features include infinite undo functionality, generation of symmetric puzzles with unique solutions, four difficulty levels, keyboard navigation, automatic resize of numbers and board when the main window is resized, as well as the ability to play the game with a mouse device.   It allows users to view the valid numbers for the current square by clicking the "hint" button, add notes or "pencil marks" to squares, automatically fill in the current square, and create "trackers" to automatically paint random entries with a different color.

Another interesting features is the ability to save and print multiple Sudokus, with or without difficulty levels. Users can view detailed game statistics while playing or at the end of a game, as well as to track additions, clear notes, view possible numbers and unfillable squares.

To play a new Sudooku game you'll have to click on a difficulty level. The program will immediately open a 9x9 grid with 9 boxes where you have to fill in the missing numbers to win the game and proceed to the next level.

The graphical user interface follows the GNOME HIG (Human Interface Guidelines) and lets users to choose between Easy, Medium, Hard, and Very Hard difficulty levels from the get-go. Unfortunately, it does not integrated with the GNOME Panel, which means that it provides a classic menu type.
