Edit2: with the 08/03 update the game is practically unuseable The game itself is addictive and fun - until you reach a level where it takes weeks to progress to the next phase. Some items are super difficult to collect and merge. Of course, if you are willing to keep buying diamonds, you're fine. When there's an update and the game prompts to have a new version downloaded, it takes several attempts to get "Update" button in the app store instead of "Play". So very irritating.
