Some games store the current game state on a server in the cloud and use the device ID to look up and load this game data.
If you start the game without any data connection (no Wi-Fi and no mobile data) and the game refuses to launch, it’s likely that the game loads its data from the internet.
In this case, try the privacy options Change Android ID, Change IMEI/IMSI and Change Wi-Fi/Bluetooth MAC address to make each clone think it’s running on a different device.
Other games use a common folder on the SD-card to store the game state. Use a file manager app to check if the game created a folder under /sdcard/ (also called Internal Storage). You can also use the File access monitor option added in App Cloner 1.5.19 to see what directories an app creates or accesses.
In this case, you can use the storage option Redirect external storage. Here, external storage refers to the internal SD-card (as opposed in private internal app storage).
