It works better if you plug it in.

279 lines in that other one (non- blank, not comment).  Looks nicer than mine.

Which causes me to ask - is there a way to get a listing of all programs on this site?
Say title, author, and size?  Or must one click and follow every thread?

We might have same taste in games, I save all Dav's so I happened to be able to find it when I saw yours.

Thing was when I searched for it his title here was Peg Solitaire but it was pegsoltaire in code so Search Engine couldn't find it. I had to go by date of post and we are up to 38 pages of Programs since 2017.

Using the arrow keys, move the cursor (barely visible, I know) over a piece and press Enter.
Circumnavigate the globe, and on the return select the direction you traveled and press Enter.
If the the start marble and end direction results in one other marble intervening between the
start marble and a blank space, the selected marble will hop to the blank space, annhilitating
the marble hopped over. 

The objective of the game is to promote air travel.  Ideally, only one marble will remain.  If
more than one marble remains and there are no legal moves, luggage in the quantity of remaining
marbles will be seized and auctioned off to homeless people in Walla Walla, Washington.
