It's a fun game & it can definitely pass the time. However...There are far to many ads. I understand they are needed....But sometimes on just one level, u may get 3 or 4 ads. You can almost count them. And sometimes, within those ads, it will glitch and the screen will go black. Either you will have to start the entire board over (with more ads) or it will completely freeze and it will take a few minutes before you can play again. Fun game but not worth all the issues to keep it...
