Angry Birds Bad Piggies Level 21-7 Walkthrough
One strategy for Angry Birds Bad Piggies level 21-7 is to lob the first white bird at a very high arch so he comes down in the third gap from the left. Drop the egg bomb at the last minute to take out the middle tower, and with some luck the platform structure should collapse as well. Now fling the second white bird high up into the first gap. Drop the egg bomb at the last minute to take out the middle tower and ideally the top left part of the structure will come down, netting you all the pigs and the gold wrench. Its collapse should also take down the middle part of the structure with the pig in it. Now use one more white bird to clean up the debris by the sand bags while also ricocheting into the top right pig. I’ve used three and four birds with this strategy. Both netted a score of 140,000+. The score in the video below is 142,860.
