After a while you will reach the point where you have to either (a) pay money or (b) invite Facebook friend to play, in order to progress further with the game. This is where I stopped playing.
Other than that, game that seem random possibly are. Sometimes you need to okay over and over again til everything falls into place, and you complete the level with ease wondering what you did differently from last time!
