Very fun game until the adds hit, ads make the game pretty much unplayable. When you first start a level you get maybe 2 minutes of no ads then boom, an add every 15-30 seconds. You can skip the ad after 5 seconds but each add has 2-4 screens that take 5 seconds for the skip button to show up. You can pay to get rid of the ads but it costs 7 dollars and ads a couple things to the game that make it less challenging. Only time I play it now is when I don't have service.
