hey guys,actually its damn easy to hack this shit to acquire some GLU credits...
it works on root and unrooted devices too..
2.extract it and u will get .gwallet folder
3.Using a file explorer(enable it to view hidden files), copy and overwrite the .gwallet folder in /sdcard/Android/data/com.glu.android.gwallet/files
4.fire up the game and u should have around 180000 GLU credits
5.go get urself a Curse Axe and start chopping like mad..
