Having issues restoring a purchase or have you purchased in game but still prompted to buy?
Firstly please check that your purchase has gone through successfully and that you have a Google receipt email.
Next please ensure the item that you purchased is correct, it's possible that you only purchased a small part of the game rather than the entire game.
Finally if you're sure you have purchased and the game isn't unlocked search for the "Restore" button which is in all of our applications. Typically it's on the main menu in one of the corners. If you tap this then the game will check again to see if you've purchased and if so unlock.
If you're still encountering problems you can reach out to: firstname.lastname@example.org sending us your Google Order ID and we'll be able to investigate or offer a refund.
