JConnect4 For Mac Publisher's description
from Edwin Olson
A free board game in Java
JConnect4 is a clone of the classic board game Connect Four (TM). It features a very strong computer player with several different adjustable levels. It's written in Java, so you can play it online now or download it and run it whenever you want.
I wrote this ages ago. It's not really a properly behaving Java applet, and it might not run on your browser. And most unfortunately, I've lost the source code, so I can't modernize it. G'luck!
