So as long as you have it saved on a Game Center or a Google Play account, you can have the base on multiple devices. Just, not at the same time, but you can definitely have your base on multiple devices at once.
Hello, I was just wondering I would be able to use my IOS device (iphone) to look at my dads base (samsung)? I cant see him on facebook freinds list even know I have added him there. I dont want to "attack" I just want to see his progression and give him tips since we live very far away and its hard to describe it to me over the phone. Dont want to make another accout, hence why I am asking it here. (honesty is key I find!)
Reversal has a good video on how to recover a Google Account through the linkage of a gmail account. It was posted but a day or two ago. Should be easy to find on YouTube. I wouldn't stress too much if your XP level was 18. With decent progression, you may be able to make it back to that level of experience within two weeks. If you mean you were at level 18 Headquarters, I am sorry for you.
I am sorry for your loss. :( I've heard things about being able to contact Supercell (possibly through email) that would contain your XP level, HQ level, and your base name (maybe gamer tag too) and they'll try their best to reunite you with your account. I am not sure if this is a rumor though, but it is worth a shot. If you think you'd want to try it out, go to the company's website for further information on how to recover an account.
