Checkers!
The applet supports 1-player and 2-player mode, and also 0-player (computer vs.
computer). Move a piece by clicking on it. It will be backlit in orange, and
then click on the target square. If there is a forced capture elsewhere, then
the piece will be backlit in blue.
If you want to play the game offline, download the archive, unzip it into an empty directory, and
open the included file index.html in your web browser.
If you are interested, you can view the details
