Obviously not. This happens to me yesterday and I thought something has gone wrong with my phone and after repeated power cycled, fault remained. What I have found out is that if I turned off the internet connection, the game ran ok with the adventure mode. So it is the internet link required by Battlez which has crashed.
I did manage to use up two free plays but would advise anyone with a long winning streak to hold off from doing Battlez for now as both games I played it crashed out after I have completed the game, the 1st one I did not lose my streak, just no rewards and the 2nd one my streak was reset as if I have lost the game even if had won.
