Angry Birds Space Brass Hogs Mirror Level M9-12 Walkthrough

Got top score by repeating @rat9‘s strat. The reason why there was such a big gap between @hoy49 and the rest of the world is that good score rely on a series of unlikely events, and that if those events do not occur, the best outcome is then several thousand points below.

So, usually, when the two TNTs explode (preferably as close to each other as possible), then send some debris upward, however those that are at the bottom of structure do not go very high, and therefore have low chance to be destroyed on impact when they fall down. Because of this, the next debris do not crash on the floor but higher, on those first debris, hence with a lower velocity and are not destroyed either. This goes on and in the end you end up with a big pile of mostly undamaged debris. If, on the contrary, the first bits of debris are destroyed on impact (a low probability outcome), the odds that the next ones are destroyed are then much higher since they reach floor at higher velocity and so on. This is the same issue as in several other levels, such as Eggsteroids-5, for example, which is even more extreme in this respect, actually.

So, my advice: keep on trying, and even if your best is only 96K, don’t despair nor think you did it the wrong way. You are on the right track (as long as you have a good method for making TNT land as close as possible to the other, of course), and need to be patient enough so that the 10k+ fluke will occur.
