I shoot the first bird same as the video.Second bird to the 3 pigs in the right,with some luck, the 3 pigs are finished by the second bird.Last, shoot the third bird to the bottom pig.

Shoot the ice bird like the video but don’t turn all the ice into stones.Some stones will fall and hit the bottom TNT.Last,finish the last pig.

I shoot the middle building and the left building and the right building fall by itself.(one bird)
