There is a battle brewing on the farm; some pigs have been stealing eggs from a group of birds and this has made them very angry. They chase the pigs, but the pigs find hiding places by building towers. The birds must now bring down the towers, kill the pigs and retrieve their eggs. In this game, you are supposed to come up with ways in which you can bring down the towers in which the pigs are hiding. This requires some observation on your part. You can clearly see how the structures have been built and you can tell where to hit in order to get the most damage. However, it is one thing to see the weak points and it is another to ensure that the birds get to hit the same spot. In order to do this, you need to launch the bird using a certain trajectory. The only way that you can achieve this is to carefully use the mouse to determine the velocity at which you will launch the birds, and also the initial delivery angle. Once you get these right, you will always hit the spot that you want. Initially, this will not be an issue since the towers are not so complex, but as the game goes on the pigs come up with ingenious ways to build their towers. This means that you will have to look for better ways to achieve your goal without using up all the birds at your disposal. For every bird that you do not use, you get 10,000 points at the end of the round. This is an added bonus and will serve to earn you very high scores. You should always aim at getting to kill the pigs with as little ammo as possible; this way you will teach the pigs never to steal eggs from the angry birds again.
