I am creating this post to help all the thieves out there who are playing on a Windows 10 device and would like to transfer their KOT account to another device. A while ago I got a new Windows ten device and wanted to know how I could transfer my KOT account from my old device to my new device. After a lot of corresponding with KOT support and a little testing I was able to successfully transfer my KOT account. Please note that it is IMPERATIVE that you follow the steps exactly as they are and not skip any or do a later step before an earlier one.
Requirements for this to work: 2 Windows 10 devices, and one Microsoft account
First you will have to create a new account on you device. So open your modern control panel.
Then click on the "Accounts" button.
Sign in to your old Microsoft account (the one that you were signed in with on your old device).
After you have successfully signed in to your old Micrsoft account it should look like this.
Open your Microsoft store and search "King of Thieves".
Then install the game.
After the game has finished downloading, open the game.
When you open the game it will ask you to choose your age. Choose it.
After this the game will ask you if you want to download your scores from the cloud. Press "YES".
Please note that if this pop up does not appear and it asks you to type in a new nickname, just close the game. Then make sure you have a very strong internet connection and open the game again. It should work then.
After that you can continue to play on your account.
I hope this will help some of you who are looking for answers on transferring your account in Windows 10.
