Go Game Connect

Go Connect 1.4 allows you to play Go on iPhones and iPads using one shared device or two connected devices. The two connected devices share their board and their real-time moves through a local WiFi network or through Apple's Game Center. Using the Game Center, the two devices can be distant.
This app does NOT 'play' Go itself - it is just a board and stones, not a player. You must know the basic rules of Go to use this app.

* Select number of handicap stones
* Touch-and-drag or tap-and-tap to move stones from container
* Touch-and-drag to move last moved stone again
* Enlarge board with a single tap; return to full board with second tap; also responds to stretch and pinch finger gestures

Is it free? The app - yes. The first 1000 stones come free with each device - try it. After that you must purchase (using IAP) stones for 3000 per $1 (about 10 cents per game). Purchased stones can be transferred from one device to other devices owned by the same user.
