You need a JAVA Browser to use this applet!
The Linux Mint 9 Live-DVD isn't compatible to JAVA 1.8.
If you can't make the applet run and really want to play, you can use the AppletViewer from the Oracle JDK and start it with the .htm file as argument. The applet should be stored at an offline location, if you use the AppletViewer.
An application version for command-line launch also exists and is more compatible.
