You can transfer your game account to any other device, provided it is linked with a Panzerdog ID on the original device.

Here is how to create a Panzerdog ID in case you haven’t one yet:

Launch the game on the new device,
Go to the settings menu,
Select «Account type»,
Turn on «Panzerdog ID»,
Press «Log in», and enter the email address linked with your Panzerdog ID.
