I play in my ipad 2, my iphone and my wife's iphone and no problems yet you just have to save your game before you play in the other idevice

Every day between ipad and iphone. Just remember to logout from one device before trying to login on the other one. It'll generally warn you if the other device hasn't saved progress. Logging out has been safest for me though you really just need to make sure it syncs.
