Why should I open the middle window of the house first in Bus Rush Fever! Level 86?

The side walls are noisy, but the board only separates once the central opening becomes a real lane instead of a decorative gap. Free the interior through the window and the frame falls apart on its own.

What usually recloses the middle window of the house in Bus Rush Fever! Level 86?

Attacking the frame from both sides at once. A smaller house with a shallow window still traps its interior, so the next route stalls behind it.

Bus Rush Fever! Level 86 Walkthrough

medium 5 colors

Bus Rush Fever! Level 86 is solved by deepening the middle window, using the purple footer to support it, and then letting one side wall empty through that path before the rest of the frame joins in. The shape looks sturdy, but the right opening breaks it quickly.

Board Notes

Layout: Level 86 opens as a house-like block with a central window. Blue side walls frame a crowded interior of green, yellow, red, and purple buses, while a low purple footer runs across the bottom. The silhouette is broad and architectural rather than chaotic.
Goal: The first target is the middle window of the house. The side walls are noisy, but the board only starts to separate when the central opening becomes a lane instead of a decorative gap.
Opening: The walkthrough opens the middle window first and uses the footer to hold the first transfers. It then lowers one side wall before the other. The roof colors are kept from collapsing too early into the same center.
Danger Zone: The trap is shaving both side walls while the window is still shallow. That shrinks the house without giving the interior a clean exit, so the next route jams behind the frame again.
Mechanics: Level 86 is a window-and-frame board. The outside walls matter less than the question of whether the interior can escape through one central opening.
