Our goal at Bingo Studios is not to make money. As of this post we don't even have any ads, nor do we want any right now.
Our goal is to make, for now anyway, games for the public that are free. No in-app purchases, no donations, no money at all. (The no money at all thing might change soon because I'm not sure that's possible.)
We are also just doing this because we love making games! We love entertaining people. We are doing what we love, and we don't love people giving us money, so everything is money-free.
Hope this helped you all realize our goal.
