Ads are constant. The game itself isn't awful, but the ads are every 30 seconds. Timers are 4-5 minutes, which is a total money grab because you either need to buy more time or watch a video. I also had a ton of stars to buy time that I earned by playing, but the first time I needed more time it was gone somehow. I'm uninstalling it and deleting it from my apps list so that I don't ever reinstall it on any of my devices. Not worth it. Deserves a 0 rating.
