This game takes some time to "give up the goods" so to say but unlike other games the game is willing to cough out the good characters eventually. What really makes the game good is the daily rewards though. They are actually rather generous and you can literally get 100s of stones from them either over time or from a special event. This will be a great game if you have a little luck and patience, and just keep playing it. Do not underestimate the login rewards. Very generous game if you take the time and get a little luck. By the way if your screen goes dim on login update your iOS to fix it.
