There are many Tic-Tac-Toe games in app store. This one is different and allows you to talk to your friends.
Tic-Tac-Toe with Voice Chat uses Apples Game Center and allows you to play this game with friends over a WiFi/3G network. The game is played between two players on their respective devices (iPod Touch/iPhone). The players can be anywhere in the world.
It is a Kids-Safe-Game-Center based app, which only allows match setup using your friends list from Game Center. Some features such as Leaderboards and Acheivements are disabled to keep the app safe for kids.
Voice Chat:
When a match is started you can voice chat with your friends. The Voice Button will not show if match has not been started.
For limited time enjoy the voice chat free. In later versions of the product voice chat feature may require activation.
Limitations:
1. Starting a match may take several seconds.
2. On some Wifi networks, firewall rules may block Game Center network traffics.
3. iOS 5 is required
Hope you enjoy it as much as I enjoyed putting this together.
