Birdday Party (Birthday Party) level 18-12 is quite difficult. The best strategy is to launch the Orange bird through the vertical wooden block in the top-left structure. As soon as the Orange bird breaks the wooden block, expand the Orange bird to push the structure to the right. With good timing, the right structure will also topple from the debris. In the video, the two bottom pigs are popped, so reaching the top-right pig with the White bird is sufficient. If necessary, use Big Brother to detonate the TNT in the bottom-left. The score in the video below is 107,360.
3-star Minimum Score: Originally, iOS devices required 105,000 points to obtain 3-stars on this level. This discrepancy has since been fixed, and all platforms observe the 96,000-point minimum.
