Quite the addictive game. But it's plagued with ads spam. To avoid them and fully enjoy the game, either buy the "no ads" thing or turn off the internet. Play without internet, no ads and no interruptions. Also, there is no cloud save, all progress is saved in the device you install the game on. There is also the issue of battery drain, there are no power saving options. Final rating: 3 stars out of 5.
