You get different birds to help complete your level, from basic red bird that will break glass and wood, to the black birds that explode after lodging itself in the countryside.You must work out your speed,height and velocity in which to fling your bird.

The pigs can bury themselves inside the glass,wood or concrete and occasionally get a golden egg for the bonus level.

There's plenty of levels to finish, some will try your patience, some are very simple, but the gameplay is addictive and the time flies when trying just one more level.good luck..when you finish this game, try Angry Birds RIO.
