While the games inside are great, there are far too many ads. You have to watch an ad in between every game and most of the ads are 30 seconds long. In addition, the game drains your battery way too much and far too fast. I was a fan for many months but they have increased the number of ads so much that I can't deal with it anymore.  UPDATE: The developer fixed a bug that was causing too many ads. Also, I decided to purchase a one-year premium subscription for $9.99 to get rid of the ads altogether. Although the app still drains the battery a bit more than I like, it's so much better without the ads!
