How many balls are fired in the recorded solution?

The walkthrough uses 20 of 26 balls and leaves 6.

Why remove both cyan sides first?

The cyan slabs brace the dark-gray core; opening both flanks lets its edge blocks and striped uprights fall outward.

The long orange base beam, small orange blocks, and a few stationary gray cubes need deliberate cleanup.

hard Target: 20 moves 6 colors

Strip both cyan flanks from the dark-gray wall, topple the striped uprights, and clear the orange base with 20 fired balls.

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

Fire into the outer-left cyan side slab and let its blocks slide off the platform.
Remove the matching outer-right cyan slab to expose both sides of the gray core.
Break the lower side braces and orange supports so the gray squares begin dropping from the edges.
Hit the exposed middle of the gray core, then wait for both striped uprights to lean and fall.
Clear the long orange star beam and isolated orange base blocks after the collapse settles.
Finish the stationary gray cubes and last small orange blocks; 6 balls remain in the video.

Colors in this level:

Gray, Cyan, Orange, Red, White, Blue

Hammering the gray center while both cyan side slabs remain attached leaves the wall boxed in.
Firing at the top of a moving striped upright wastes the shot instead of removing a stable base target.

Board notes 5 details

Layout: A broad dark-gray square core is wrapped by cyan side slabs, orange star beams, two red-and-white striped uprights, and a low orange-and-red base.
Goal: Remove the cyan wrapper, collapse the gray center and striped posts, then clear the surviving orange base blocks and gray cubes.
Opening: Break the outer-left cyan slab and then the matching right slab so both sides of the gray core lose their armor.
Danger Zone: A leaning striped upright should be allowed to fall; repeatedly shooting its moving top wastes balls needed for the orange base.
Mechanics: A removable two-sided cyan wrapper releases a dense gray core and delayed striped-post collapse.
