No one really knows when PEG solitaire was invented. Some stories trace it 
to prisoners during the French Revolution, but published descriptions date 
at least 100 years earlier.  Most likely the game is even older.  PEG 
presents variations on the classic peg solitaire with multiple starting 
positions, and varying endgames.  One of the pleasures of playing the game 
on your computer is that you can quickly set up the board to try different 
strategies. Ages 8 to 88.  Requires mouse/EGA.
