I am a big fan of this particular game and I have been playing this game from quite some time. Still I do not how to get the three stars in the every level of the game. I have crossed literally each and every level of this particular game and still I am unable to find the methods by which I can get the three stars in the every level of the game. Do I need to kill all the birds as efficiently as possible, or are there rules to it? my sister who is also a big fan of this particular game yesterday asked me the same question regarding this particular issue and I answered her the same that I do not know. So any of you who knows how to add the three or two stars in each and every level then do let me know about it.
