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
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.
It's not as daunting as it looks, actually. Your exploding bird must land in amongst the concrete directly above the second pig from the left (about halfway up the structure). When it explodes it will take out the first three pigs in one hit. Remember that you can pre-detonate a bomb bird even after it's landed and gone red to time your ordnance perfectly. This leaves your MOAB birds to clear the smashed and fallen masonry from above the last pig and let the shockwave from the last one kill the porker. Good luck!
Aim the black bird at the row just under the first dice and DON'T explode him. If you hit it right he will explode and take out 3 of the pigs. Then you are left with the two white birds to get the last pig on the end.
