I have linked 2 devices to my game center.

Right now what I am trying to do is create a third account of the game to play on 2 devices.

One way is to create a new account using a new device then linking it to my game center so I can play 3 accounts on 2 devices.

However I do not have that third temporary phone. Is there anyway I can create a new device using either one of my current phone? I am assuming that if i lose the account on one of the phone, that is fine because it has already been linked to game center and I can access that lost account using my other phone?

Please help!
