I've beaten the pig on Pig Bang level 1-30 with two or three birds and got 73760 as my highest score, which is enough for two stars. I'm guessing the 3-stars score is around 75k. The problem is that there's not much in the way of points in this level, and I don't think I can beat it with just one bird. I'm stumped as to how I can 3-star this, any ideas?
(Un?)fortunately, Angry Birds is pretty much non-deterministic for touchscreen devices, so sometimes you just have to keep trying and hope you get lucky. This is especially true for this level.
The general idea here is to create a chain reaction where one rock would burst the bubbles of the other ones. Both vegetables and rocks can burst bubbles, but only rocks can damage the vehicle. It takes around 4 rock impacts to destroy the pigmobile. Since gravity is at work here, aiming higher helps.
Here are two not-very-helpful screenshots that'll hopefully illustrate the idea. And yes, getting 76k requires you to only use the first bird.
