Play rock, scissors and paper.

You pick one of Scissors, Rock and Paper. At the same time (trust me, no cheating) the computer picks one too.

The winner is decided on basis of the following 3 rules.

1. Scissors beat Paper (cuts)
2. Paper beats Rock (contains)
3. Rock beats Scissors (breaks).

To make your result reasonably significant you should play at least 100 times.

If the applet does not start, you should update your Java VM. All you need is Java Runtime Edition from http://java.sun.com/j2se/1.4.1/download.html.
