Break the upper-right red-orange star crates and continue down the right seam.
Let the loosened right wall and its red round blocks fall outward.
Remove the exposed right white panel and the crates beneath it.
Hit the lower edge of the dark-gray core so its upper blocks begin to step down.
Open the remaining left shell and wait for the orange crates to slide away.
Clear the reduced gray center stack from its bottom support upward.
Remove the stationary orange base crates on the right, then the separated left-side pieces.
Shoot the final isolated crate or gray block and wait for the win overlay; 4 balls remain.

Shooting the dark-gray core while the right shell and white panel remain intact wastes balls against a braced center.
Cleaning scattered orange crates before the gray stack settles can hide the true final support.

Peel the upper-right star-crate seam before touching the dark-gray center.
Remove the exposed white right panel after the outer wall falls.
Attack the reduced gray stack from its bottom support, then clean the orange edges.

Board notes 5 details

Layout: A rectangular red-orange star-crate shell surrounds a dark-gray core, with white lower panels, red rounds, and a low orange base.
Goal: Drop the right shell, dismantle the exposed gray core, and remove the separated orange edge crates.
Opening: Strike the upper-right and mid-right star-crate seam so that side falls outward and uncovers the core.
Danger Zone: The gray center remains boxed by crates and white panels, so early direct center shots leave both shell walls standing.
Mechanics: An asymmetric shell peel reduces the ornate wall to a compact-core and edge-crate cleanup.
