#OX is a simple Tic Tac Toe game where you can play against the iPhone, another player, or another player on the Apple Watch paired to the iPhone.
You can now SharePlay with others on a FaceTime call or over Messages, in addition to playing with other players nearby!
On iPhone you can play against iPhone, another player or a player on the paired Apple Watch.
On Apple Watch you can play against the watch or play against a player on the paired iPhone.
Hand your iPhone to a friend, family member or kids and challenge them to a game from your Apple Watch, fun for the whole family!
You can't play two player watch vs watch. And there's no return button in either the watch app or iPhone app. App if you hit the wrong play on the watch you have to wait approx 2 min before opening the app again to play single player. The same with the iPhone app. Poor made app, don't know why apple has approved this.
