Just like Android had one a couple of weeks ago, EA has released an update for Tapped Out for iOS users only. Nothing visibly different, as far as the external display on the game, so most likely this is just an update on the files of the game.
Could be fixing a glitch or two or it could be prep for an upcoming event or update. Either way if you’re playing Tapped out on iOS be sure to go to iTunes and update your game!
Happy Tapping Friends!
