First, please do not open a second account or you may delete your original one. Neither use any cheat or hack in the game, or even VPN, as all of this can cause the loss of your account after an update. To restore your account, first, you need to have it linked. Then, just go to the symbol of the image below, and press it. Then select the mail account that your game account was linked to, the one you used on Google Play or iTunes when you linked your account, and you will be able to restore the progress without issues. If you did not link your game account, before any event of failure or loss of the device, you will not be able to recover your account. TinyBytes is not responsible for the loss of accounts in players who have not correctly linked their devices.
