At least 1xday and sometimes many more, I will be in the game and it will suddenly give me a black screen and then go back to the home screen of my iPad. This often happens when I am doing well in the game, have just purchased new lives or additional moves, or have accessed a booster. When I go back into the game after this, the life or booster will be shown as spent. I am on Level 926 and am playing the game on an iPad 3 with iOS 9.3.5.
