Here is my strat. I count it as a new strat, but I think it corresponds to what @rat9 and @burpie reported. At least it got inspiration from them, so thank you guys. And in any case, it is one of the weirdest billiard trick I have ever seen on AB Space, so that I think it really deserves a detailed description.

1. Aim Bomb toward the bottom, middle sized boulder. If you have an Iphone, it is the one which is partially off screen even if you zoom out at most. The shot is therefore difficult to do on an iPhone, but on other platforms, it shoud be OK.

2. Aiming direction is (I think) the one that goes as close as possible to boulder without breaking it on activation (on the following screenshot, it is actually a bit more to the left than my orange line). Since there is a complicated billiard combination ahead, medium boulder initial velocity must be as large as possible.

3. Activate so that boulder goes at 1:00, i.e. toward the *second* closest big boulder (I could not find anything to do with the nearest one).

4. Precise activation point must be derived so that when medium sized boulder bounces on the bigger one, the bigger one has to be deflected a liitle bit more on the right (i.e., at 1:30, or 1:15), toward gem.

5. Now the crazy part of the story: the gem cannot be moved an will break on impact with big boulder. But since big boulder goes quite slowly at this point, it will bounce on the gem when breaking it. There is some spossibility that this will drastically change its direction, toward 9:30, i.e. the small bubble pig. The bubble will pop when boulder will reach it, but boulder now has such a low momentum then that it will bounce on the bubble, subsequently going toward 11:00 if all goes well (at this point, making this shot it wery ncommon, so that I cannt give any probability of outcome). Ultimately the big boulder will hit the medium sized boulder, sending both toward the gravitational field and clearing the crystal and fat pig.

A small sketch of what happens:

Orange line is approximate initial Bomb Bird trajectory (actually more to the left than what is shown). Green line is approximate medium sized boulder trajectory after BB activation, and yellow line is the crazy big boulder trajectory.

In one hour, I could destroy the crystal planet twice with this strat. The first time, the big boulder directly went from the gem to the 2nd medium sized boulder, so that I ended up with 50k and the small pig left. The second time, everything went fine and I got the top score. Since this was the first time I succeeded in doing what I was trying to, there are probably a few hundreds points more that may be available when repeating the move, but it is too difficult and hence too rare to perform (for me) to really want scratching them.
