Game has potential but the developers have it rigged like a carnival game to waste your time. The side challenges such as Sweep the Board are literally impossible- I got so frustrated that I will never try again. I understand wanting to make it challenging but to make it impossible unless you pay money is ridiculous. If you want a game to pass the time at work, forget about it because you only get a few minutes of play time before you have to wait until the next day for it to recharge.
