LEVEL 755

THIS IS DRIVING ME CRAZY CANT GET RID OF LOWER LEFT SIDE WITH GEMS IVE TRIED EVERYTHING THX ALOT!!!

If I'm right, this level has the same scenario as levels 377 and 215 and 125.
This is my solution to those levels:

"At first, break the box to the right. There is a rocket under it and it will fall down to the lowest middle square. This will break both rocks, but the rocket MUST fall down to the lowest square, where you have to explode it.

If the left box breaks first, the token which is under it will go down and the rocket will not go where it is supposed to go."

Any help?
