This game is constantly updating with worse and worse changes. ANYTHING you want to do cost coins. Which are very, very scarcely handed out as rewards, or you just have to buy with real money (which still isn't even a good deal). I'm surprised it doesn't cost coins to place a tile on the board... yet. AND this game doesn't like to give the rewards that you earn for leveling up and completing challenges. I like this game in theory, but this is getting to be too much.
