Wreck the Halls level 15 is a fun level with several different approaches. Our strategy is to loft Big Brother through the snow in the top-left. The stones will fall and damage the left-hand-side, while Big Brother will damage the right. Use the first Yellow bird low to pop the pig in the bottom-left. Use the next Yellow bird to take out the snow in the top-right, causing the stones to crush the pig in the bottom-right. The score in the video below is 88,860.
