Playing online games in Backgammon requires devices that support Apple's Game Center technology.
Online gameplay allows you to play against random opponents or invite your friends.
iPhone 3Gs
iPhone 4
iPod Touch 2nd Gen and newer
iPad
When you don't see the Online button in the main menu, this is because your device doesn't meet the minimium requirements for Game Center. This
could be because you haven't updated to iOS 4.1 or newer or because your hardware is not supported by Game Center. For a list of supported Devices,
see the "What devices are Supported" FAQ.
Occassionally you might see this error message popup. There are a number of things that
might cause this to happen:
1. Your device's date and time are incorrect. Check the date and time in the settings app
2. You device may need to be restarted
The most common cause of this problem is having your notifcations and/or Game Center notifications disabled. Game Center requires notifications
to handle friend requests and game invitations. Both users must have notifications enabled.
To Enable Notifications
Go to the 'Settings' application
Select the 'Notifications' menu
Verify that notifications are "on"
Check the Game Center App settings. Make sure that all notifications are enabled (Badges, Alerts, Sounds).
