There are like 50 billion games on the App Store and a lot of them have Game Center integration so you can battle your friends at Angry Birds, or Temple Run or Tic-Tac-Toe or whatever. But if you want to see how much your friends really love you, try playing them in a emoji game of Connect Four. It’s painful and kind of tedious and you have to remember to play with virtual-gravity, but it’s also totally awesome, in a dumb way.
