Currently the site includes programs for playing the games Sudoku, Kakuro, Sokoban, Minesweeper, Boggle and SCRABBLE, plus the set of programs used to make this website. The programs can be downloaded for free and are very easy to install on Linux and Windows. They are written in the languages Python and Tk and the download includes the source code. This may be useful to other aspiring programmers, even if only to show how not to write Python and Tk.
The programs are written in the Python language and are distributed as source code under the GNU General Public License. This means that you can modify and redistribute them as long as you include the source code.
Do not worry that the programs are distributed as source code: Python programs are interpreted as they run so no compilation is required. Installation couldn't be easier: just download the source file and the programs are ready to run (assuming you have the Python libraries and interpreter installed).
