Well it iss possible to play 1 account, on multiple devices.(same Operating systems (OS) )
Just login game center on the 2nd device with the apple id of the main account you would like to play with.
Then download the game via the apple id(appstore) and you will have the main account in the second device.
What is NOT possible (yet): play your android account on an ios device and vice versa.
