+GNOME Sudoku has a simple unobstrusive interface
+while still providing features that make playing difficult Sudoku more fun.
+All games are automatically saved when you quit so you don't have to worry about saving games.
+You can always come back to any game you've played.
+</p>
+<p>
+If you like to play on paper, you can print games out.
+You can choose how many games you want to print per page and what difficulty of
+games you want to print: as a result, GNOME Sudoku can act a renewable Sudoku Book for you.
+</p>
+<p>
+Each game is assigned a "difficulty" score - its algorithm generally does a good
+job matching the difficulty rankings typically given by newspapers and websites.
+You can also see detailed difficulty information about how the computer solved
+the puzzle.
