For a long time, Multiplayer worked across platforms, 2 iPads, 2 Kindle Fires, and a Samsung tablet. Suddenly, they got glitchy and you would have the clear all apps, and try several times, to connect. Now, as of about October 2015, there is NO multiplayer function at all. It never pops up to join a game, no matter where ch way you try, hosting from any device. It seemed to occur after one of the October updates. I have searched forums, and there are complaints about it everywhere, but nothing has been done to address this.
