If your game crashes or freezes at random points, we suggest that you follow these troubleshooting steps that usually help to resolve most technical issues:

- Exit the game.
- Exit all other apps running in the background.
- Reboot the device.
- Turn your Wi-Fi off and back on again, then make sure the signal is strong enough.
- Relaunch the game, making sure that it's the only process running.
- Reconnect to your account.

If it still doesn't work, you can try to reboot your router. We also recommend that you clear some space on your device for proper game performance and clear the cache of the application:

- Go to the device's Settings
- Tap Applications
- Select Manage Applications
- Scroll to find the game, then tap the app icon
- Tap Force Stop
- Tap Clear Cache
NOTE: Do not touch the Clear Data icon.

In addition, you may also try these other steps:

- Upgrade the operating system and the application to the latest version.
- From time to time, restart the device to free up some memory.

If the problem persists, please delete the game from your device and re-download it.
