Break the upper-right orange outer column beside the dark gray chamber.
Hit the short orange beam beneath that chamber so its right side loses the second brace.
Pause while the gray blocks and orange roof beams slide off the right side.
Break the central horizontal orange divider now exposed above the red orb rows.
Remove the right orange upright beside the red orbs, then the matching left upright.
Clear the stationary red orb blocks as the lower frame spreads across the platform.
Shoot the remaining orange base crates from the outside toward the pedestal.
Remove the last long orange beam and small red remnant; the level ends with 9 balls.

Colors in this level:

Orange, Gray, Red, Blue

Starting on the red orb base keeps the top chamber stacked above intact supports.
Firing during the gray chamber's slide can strike moving debris instead of orange dividers.

Board notes 5 details

Layout: A tall orange star-crate frame stands on a narrow blue pedestal, with dark gray blocks in the upper chamber, red orb blocks below, and orange beams between the layers.
Goal: Tip the gray upper chamber to the right, dismantle the orange lower frame, and remove the last red orb blocks and orange beam.
Opening: Break the upper-right orange outer column, then the short orange beam directly beneath the gray chamber so its right side loses both braces.
Danger Zone: Breaking the red orb row first leaves the heavy upper chamber protected; wait for gray blocks to slide off before resuming.
Mechanics: A top-heavy one-sided collapse exposes a compact orange-and-red cleanup on a narrow pedestal.
