如何在憤怒的小鳥中通過 3-15 級？

我無法在憤怒的小鳥中超越這個級別。我得到的只是一隻黑色的爆炸鳥和兩隻白色的轟炸機：

我可以用黑色轟炸機殺死剩下的兩隻豬，但是在那之後，其他豬的頭頂上有這麼大的混凝土堆，我什麼都沒有穿過。

這是 3-11 到 3-15 的影片演練：

Youtube has a bunch of these:

This is the “Official Angry Birds 3 Star Walkthrough Theme 3 Levels 11-15”

A description of what occurs in the video:

1. Fire black bird at gap between concrete levels 3 and 4 (one above first die).
2. Black bird explodes on top of second tall wood column. Second pig is
  destroyed.
3. Fire white bird on slightly higher trajectory, dropping egg between third
  and fourth (now second and third) pigs, destroying both.
4. Fire second white bird on lower trajectory, dropping egg between first (and
  only) remaining pig and die, destroying both.

Total points in example video: 56460. ★★★
