I give 2 stars because the game is entertaining. However I can't give it more because the advertising claims free bingo game. And that's partly true. You can play for free. But you can't be competitive without spending money. And that sucks. Not everyone has the extra money to pay for power ups. And you start with a lot. So you can compete for a short while. Your behind and you stay there. The daily recharge leaves you short. So unfortunately just another game designed to get you to pay$$$
