Pretty solid Peg Solitaire fun! A good selection of boards and puzzles. Personally I prefer the board game since I can undo moves, cheat, or throw the board to the floor in frustration. That said, you've done a good job.
Thinking to future editions: there are actually several variations of the French board, and probably the others too. I would really love to see an undo move button (for as many moves as I want) (this can also be used to give point system: 10 points for removing a peg, -1 for using undo!). And then when a player completes a board, the game can undo all the moves, leaving peg trails behind... (colour dependant on how late the move was?)... this would give interesting rainbow patterns!?!
