Break the right brace, peel off the cyan roof shell, and empty the bunker in 16 shots.

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

Shoot the lower joint where the right slanted cyan brace meets the bridge and right wall.
Keep firing through that same right support until the brace peels away and the right side of the cyan shell starts tipping off the bunker.
Wait for the roof strip, top cyan caps, and loose bridge blocks to fall before using more shots.
Trim the leftover left cyan slab and any bridge piece still covering the orange drum bunker.
Work through the exposed drum bunker from the upper middle down to the base until only one orange drum and one cyan cube are left on the tabletop edges.
Finish the right-lip cyan cube and the last drum on the left lip with 10 balls left.

Board notes 5 details

Layout: A long orange roof plank sits on three cyan cap cubes and white spike-and-ring modules above a lower bunker of orange drums, one tall left cyan slab, one right white-blue column, and a slanted cyan brace on the right.
Goal: Detach the right brace and bridge cover so the upper shell peels away, then clear the exposed drum bunker and the last cube-and-drum lip pair.
Opening: Start on the lower joint where the right slanted cyan brace meets the bridge and right wall.
Danger Zone: Center drum shots do very little while the roof shell is still pinning the bunker together, and the late right-lip cyan cube still props up the last drum.
Mechanics: A roof-over-bunker collapse where the right brace must be peeled first so the lower drum block stops behaving like one packed wall.
