Why are several colored windows visible at once?

The tower exposes different ledges as it re-presents. Visibility does not change the target order; use the active boxes as the route.

Does the board become safe when it shrinks?

No. The late stack is smaller, but the buffer remains finite and the gray/red end groups still need the correct order.

Open Level 19's orange-brown question-mark tower from cyan and blue, then follow yellow, green, pink, red, and gray target phases.

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

Clear the exposed cyan 2 and blue 4 windows from the opening target row.
After the tower re-presents automatically, take the yellow/green groups on the newly exposed ledges.
On the lower ledges beneath the question-mark tower, take pink and then red from the newly exposed windows; the upper cover remains blocked.
Before the gray and final red phases, preserve buffer space for the active window rather than storing a visible color that belongs to a later ledge.
Clear the last red group from the small lower cluster after its target box appears, then wait for WELL DONE.

Colors in this level:

Cyan, Blue, Yellow, Green, Pink, Red, Gray, Orange, Peach, Purple, Lavender

Start with the exposed cyan 2 and blue 4 windows in the opening row.
Let the tower re-present automatically, then choose the yellow/green ledges named by the new boxes.
Keep capacity for the later gray and red groups; a nearby window can still belong to a later phase.

Board notes 5 details

Layout: The opening board is an orange-brown question-mark tower with colored cubes protruding from windows and ledges. Cyan 2 and blue 4 are active, and the buffer row is empty.
Goal: Advance from cyan/blue through yellow/green, pink, red, and the final gray/red groups as the tower reduces.
Opening: Clear the exposed cyan and blue windows before reaching into the brown cover.
Danger Zone: Multiple colored windows can be visible at once, but out-of-order taps can store a color that is not immediately usable.
Mechanics: The ledged tower re-presents automatically and collapses into a sparse colored cluster as target groups clear; no manual swipe is established in the source. Different windows can be visible at once without being equally available.
