Back in 2001, I wrote this little game of solitaire, themed for Trench Sniping on the Western Front of World War One.

It’s pretty bare bones, but the good news is that you dont’ need much of anything but a deck of cards and something to keep score on to play. Have fun, the link is to a Calameo (web document) page.
