THE GAME'S Algorith IS SET TOO HIGH AND IT DEFINITELY MAKES IT IMPOSSIBLE TO BEAT BECAUSE IT CHEATS UNLESS YOU USE GEMS TO RESTART, AND EVEN THEN IT MAKES IT EXTRA DIFFICULT. THIS IS VERY OBVIOUS ESPECIALLY WHEN YOU ARE PLAYING IN THE ARENA. THE COMPUTER SEEMS TO ALWAYS GET 2 OR 3 XTRA BIRDS IN THE SAME ROOM IF YOUR BEATING THEM!!!! This game is set up to tempt you to buy their stupid gems just to get cheated out of them!!!!!MY own clan has complained to customer service, without any assistance
