Four In A Line is a multiplayer Connect Four game. It can be played on a network, or against an AI game player.

The AI game player uses the algorithm developed by Keith Pomakis but then rewritten in Java.

The network layer uses RMI without using the callback pattern, which ensures that the game will be compliant with firewalls.

Connect Four is a trademark of Hasbro.
