hard Target: 19 moves 6 colors

Clip the upper-right pole cluster, fold the orange bridge open, and clean the exposed icy base in 19 shots.

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

Fire into the upper-right pole cluster, aiming at the support just beneath the leaning brown pole and blue cap.
Hit the right orange shelf again so the top pole and side aqua pipe start peeling away from the crown.
Keep working that same upper-right opening until the pole cluster loses its grip and falls away from the bridge.
Pause for the collapse, then shoot through the exposed middle bridge and the dark anchor blocks behind it.
Break the icy lower stack that was hidden under the bridge once the orange bars and right crown are out of the way.
Use the final shots on the remaining base tiles and any loose side pipe or cube still sitting on the platform; leave 3 balls.

Colors in this level:

Brown, Blue, Orange, Gray, White, Purple

Starting on the left aqua staircase while the upper-right crown is still intact.
Ignoring the dark bridge anchors after the pole cluster has already fallen away.

Open the upper-right crown before touching the lower icy stack.
Wait for the tall pole and side pipe to fall away before shooting through the bridge.
Use the last balls on the exposed base tiles, not the intact left staircase.

Board notes 5 details

Layout: Three tall brown poles with blue caps sit above orange bridge bars, aqua side pipes, dark anchor blocks, and a lower base of pale icy tiles.
Goal: Topple the upper-right crown first so the bridge opens and the hidden icy base can be broken apart.
Opening: Attack the upper-right pole cluster and the orange shelf beneath it instead of shaving the left aqua staircase.
Danger Zone: The left staircase looks easy to trim, but it does not release the bridge or the leaning crown.
Mechanics: A pole-topple bridge board where the high right cluster must fall before the middle shelf and icy base become efficient targets.
