Why does the boss square feel stuck in Block Out Level 37?

Because the two `1`-counter blocks directly below it are still in place. They look trivial, but the boss cannot drop until those support blocks are removed and the lower lane is clear.

What is the cleanup phase in Level 37?

After the boss falls around 01:11, pink and blue blocks remain on both sides of the board. These are a second phase of color sorting through the side and bottom exits.

Block Out Level 37 Walkthrough

hard 4 colors

Block Out Level 37 centers on a large orange-framed boss square with a `7` counter. Two small `1`-counter support blocks sit directly under the boss and must be separated first to create a drop lane. The green blocks at the bottom drain early, the side blue and pink blocks thin next, and the boss finally descends once its lower lane is clear. After the boss falls around 01:11, a second wave of pink and blue blocks remains for cleanup.

Board Notes

Layout: A large orange-framed boss square with counter `7` dominates the center. Small pink/red flag markers sit above the boss. A yellow vertical bar runs along the left wall with blue blocks stacked above it. More blue and pink blocks fill the right side. Two small blocks each with counter `1` sit directly below the boss. Green blocks occupy the bottom of the board. Exits: blue arrow at the bottom, arrows on the left and right walls.
Goal: The two `1`-counter blocks below the boss must separate first to create a drop lane. The green blocks at the bottom are early exits that open the lower space. The blue and pink blocks on the sides are what keep the boss pinned — they need to thin before the boss can start dropping. After the boss falls, pink and blue blocks remain for a second cleanup phase.
Opening: Start with the left yellow bar to open the left side, then clear the green blocks at the bottom through the blue exit. The two `1`-counter blocks below the boss are next — once gone, the boss has a downward lane. The blue blocks on the right then begin shifting. By 01:17, the boss counter has dropped to `5`.
Danger Zone: Pulling on the boss square before the `1`-counter blocks below it have cleared is the trap. The boss is a large square and needs vertical space to drop. If the lower lane is still occupied, the boss cannot descend and the side blocks have nowhere to shift. The boss finally clears at 01:11 only because the lower lane was opened first.
Mechanics: Level 37 is the first boss-square level in this range — previous bosses were columns or panels. The square boss takes up more horizontal space, so it needs lanes on both sides and below to drop. The small `1`-counter support blocks underneath are a new pattern: they look trivial but are actually the gate that allows the boss to move.

Quick Tips for Block Out Level 37 (spoiler-free)

The two `1`-counter blocks below the boss look small, but they are the gate — until they are gone, the boss has no downward lane.
Green blocks at the bottom are early exits. Clear them first to create lower space.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Block Out Level 37 — Full Solution

Slide the yellow bar on the left to open the left side lane.
Clear the green blocks at the bottom through the blue exit arrow to create space below the boss.
Remove the two `1`-counter blocks sitting directly under the boss square.
Shift the blue blocks on the right side to give the boss horizontal room.
As the boss counter drops toward `5`, continue thinning the pink and blue blocks on both sides.
Let the boss square drop through the cleared lower lane once the counter is low enough (visible at 01:11).
Finish the remaining pink and blue cleanup blocks after the boss is gone.

Common Mistakes to Avoid

Trying to lower the boss square while the two `1`-counter support blocks are still in place — the boss needs a clear vertical lane to drop.
Clearing side blocks before the bottom green exit is open, which leaves the lower area packed and gives the boss nowhere to fall.
