How many balls does the walkthrough use?

It fires 16 of 21 balls and clears the level with 5 remaining.

Why open the left bay first?

Removing its gray cap and striped support gives the rest of the wall room to lean and collapse.

The tall orange star pillars and one small red star crate need direct cleanup shots.

Open the left bay of the striped three-column wall, topple the remaining frame, and finish the exposed orange star pillars with 16 fired balls.

If the player asks you to sign in, open the video on YouTube instead.

Break the upper-left gray cap and adjacent striped blocks.
Continue down the opened left bay until that striped column falls away.
Hit the center striped supports, then pause while the right column leans inward.
Remove the exposed right striped stack and the small red star crate at platform level.
Knock down the left and middle orange pillars.
Shoot the final upright orange pillar; leave 5 balls.

Colors in this level:

Red, White, Gray, Orange, Blue

Starting in the dense center keeps both side frames braced and spends balls without opening a fall path.
Firing at orange pillars through moving striped debris causes shots to be intercepted.

Board notes 5 details

Layout: Three red-and-white striped bays stand above a lower row of tall orange star pillars, with dark gray caps bracing the upper outer edges.
Goal: Remove every striped column, then knock the three orange pillars and the last small red star crate off the platform.
Opening: Break the upper-left gray cap and striped blocks beneath it so the wall starts peeling from the left.
Danger Zone: Do not shoot the orange pillars while striped pieces are still falling across the firing lane.
Mechanics: A left-to-right framed-wall collapse exposes three isolated vertical pillars for the final cleanup.
