4-21 3 Birds
Aim first yellow bird at metal at top of first tower. Generally aim at middle of mass of metal at top, but exact placement not that important. More important is timing of release of second bird.
Aim second yellow bird at roughly the same spot as the first bird. Time acceleration so that bird strikes as tower is leaning to the right. Tower must topple at this point to continue for high score. Also, tower must topple from top to bottom. If only top tumbles a high score cannot be achieved.
Aim third yellow bird to pop remaining pig(s) at far right of structure.
(Note: this game can be completed with just the first two birds, but was not able to do it on the computer)
