This applet requires jdk 1.1 or later and swing 1.1

This also runs as a Java application. Grab Tetris.jar and run it under jdk 1.2 using the command: "java -jar Tetris.jar".

The keys are:

Drop to bottom of screen:space
Drop one line:k
Move left:j
Move right:l
Rotate left:u
Rotate right:o
Pause:`

Sorry, it looks like my web publishing software has filtered out the app tags - you can try running this program as a java app.
