SuperTac is Tic-Tac-Toe on steroids. The object of the game is to get five X's or O's in a row.

Play over the Internet!
SuperTac is cross-platform (Mac OS X, Mac Classic, and Windows) and playable over the Internet, allowing you to challenge all of your friends from around the world.

Emo-Tac-ons
There are four audible emoticons in SuperTac. Clicking one of the buttons will send a text message and a sound to your opponent. If your opponent is taking too long to move or you're angry that you're losing, let him know how you feel.

Chatting
You can send text messages back and forth with your opponent using SuperTac's built-in chat window.
