This game cheat tool will only work for offline games and will require a rooted device, emulator or phone.
If you want an alternative app that does not require a root and allows you to hack apps with no root, then download HackerBot APK instead.
Game Killer is a good alternative for older devvices to replace apps like GameGuardian, Game Hacker, GameCIH, Lucky Patcher or Freedom APK.
