3 stars: This is a great game but it only lasts a few seconds before an advertisement comes up for some other game. After that every time you press the screen another advertisement comes up. It becomes quite annoying it actually gave me a headache and I just quit playing it. I would love for the game to last at least a minute, a full 60 seconds before all these advertisements come up and they can be quite confusing. SMH.
3 stars: Fun game, but you've allowed to many, persistent and constant adds inbetween rounds and that it makes it frustrating to play, so I don't recommend downloading this game purely for the invasion of adds you'll come across, I'm deleting the app for this reason.
2 stars: Was fun... until I couldn't upgrade any more. Now there is no winning as the levels are too hard. No telling if upgrading is activated after paying for the game. But I put my time into a million ads just to enjoy the gameplay.. time to delete as it's not fun playing a game you can't win.
