Open the upper-left shelf, expose the yellow cylinders, and finish the tower with 20 fired balls.

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

Shoot the upper-left crown blocks and the left shelf support until the top layer starts leaning away.
Continue through the left-middle shelf so the orange crates fall outward and the purple cans lose their cover.
Pause for the leaning shelves to settle, then attack the center-right stack that still hides the yellow cylinders.
Remove the upright white beam with red caps and the nearby purple can that keep the cylinder cluster boxed in.
Clear the yellow cylinders on the platform together with the short white beams beneath them.
Finish the last purple can, stray star crate, and any small white cap still resting on the base; leave 5 balls.

Colors in this level:

Orange, Purple, White, Red, Yellow, Blue

Starting on the tall right column before the left shelf has opened the middle.
Ignoring the yellow cylinder cluster until the platform is already crowded with fallen beams.

Board notes 5 details

Layout: Three stacked shelves mix orange star crates, purple cans, white horizontal beams, and a lower-center cluster of yellow cylinders hidden inside the tower.
Goal: Peel the left crown, expose the yellow cylinders in the middle, and clear the last beams, cans, and star crates on the platform.
Opening: Shoot the upper-left crown blocks and left shelf support so the top layer leans and starts opening the center.
Danger Zone: Tunneling into the tall right stack too early keeps the yellow cylinders buried and wastes shots on beams that would have fallen on their own.
Mechanics: A shelf-and-cylinder release uses the upper-left crown as the trigger before a platform cleanup around the exposed cylinder cluster.
