The developers will tell you this game is free to play, and yes it is free to download and play. What they won't tell you is in order to progress anywhere in this game you need to pay pay and pay some more. And then there is the ads. Loads of ads. From the same scam developers over and over. Those long ads that you have to click 3 times to close at the end. Gameplay is good, but you get stuck very quickly if you don't upgrade by paying. The ingame ugrades will never help you progress.
