Open the right seam of this pink cylinder curtain, expose the brown posts, and let the wall avalanche in only 4 shots.

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

Fire into the upper-right interior seam of the pink curtain, just inside the outer brown column.
Repeat through that same seam so the first curtain panel peels away and the brown posts show through.
Pause while the right-side curtain avalanches and the center stack narrows.
Use the last two shots on the remaining center-right cluster and any stubborn pink strip still hanging to the brown post; leave 27 balls.

Pink, Brown, Orange, Red

Shooting the untouched middle face before a side seam has opened.
Switching away from the first break before the right curtain panel has fully peeled loose.

Board notes 5 details

Layout: A tall rectangular curtain of pink cylinders hangs around several brown vertical posts on a narrow platform, with the real support hidden just behind the outer skin.
Goal: Peel open one side seam so the brown posts lose their support and the curtain wall falls in large sheets.
Opening: Fire into the upper-right interior seam instead of the untouched middle face.
Danger Zone: The center curtain looks broad but only absorbs damage while both side skins remain attached, so switching to the middle too early wastes shots.
Mechanics: A seam-peel cylinder wall where one opened edge triggers the main avalanche.
