Your Glu credits can show a small negative balance if certain situations, explained below, are met. A very large negative balance will require an investigation by our team, so you should click on "Contact Us" if that is the case.
Here are 2 of the most common situations:
1-If a game is started on a Wi-Fi connection and then the connection became unreliable or the device keeps moving from a Wi-Fi zone to no Wi-Fi, the servers may not receive all your actions. When the connection is established again it will get updated all at once, which can lead your balance into negative territory.
2-If you play on multiple devices and you access your shared Glu Credits at the same time then this can cause a negative balance. It is not recommended to play on multiple devices.
Note that Glu credits for this game may be shared between games rather than belonging to any one game, so anywhere you choose to spend them will show a reduction across all those games. This is true mainly for older Android titles that shared balances.
Important: GGN only saves currency to be shared within GGN-enabled games. It does not save game progress online like levels or items. To prevent progress loss: Please DO NOT uninstall Glu games.
