Hi people, the Iap crack thing works, just go on battlegems, click on upgrade (or unlimited energy) the game will crash to desktop, turn off your internet (wifi connection) and go back to battle gems and press on upgrade again (or unlimited energy) there will come an error press OK and just equip the dragon thing armor from the inventory (press on more items) then put on the internet (wifi connection) and just play then goto upgrade (or unlimited energy) and TADAA!
Only for iOS (iDevices that can run BattleGems)
