If you don't pay money, the game is tediously SLOW. The app owners should say up front "we want at least 10 bucks from you if you expect to make any progress and remember what your tasks are." For example, it takes more diamonds or coins or whatever, to buy a pet. You can't interact with Hagrid if you don't have a pet. You COULD get more gems, 3 at a time, and spend hours of your time to gain minutes of game play. Is the game any good? Can't tell, because I don't like extortion games.
