Why is the middle neck so important in Bus Rush Fever! Level 81?

If that connection stays crowded, the towers never become real routes and the bottom bar just absorbs clutter. Open the neck and the wide base finally has a single lane to drain through.

What usually keeps the middle neck from opening in Bus Rush Fever! Level 81?

Flattening the long base while both towers still feed in. The board looks shorter, but the neck is unchanged and the next drop jams at the center.

Bus Rush Fever! Level 81 Walkthrough

medium 3 colors

Bus Rush Fever! Level 81 clears best when you open the middle neck first and make the two short towers use that same route one at a time. The wide base only becomes valuable after the center stops being shared traffic.

Board Notes

Layout: Level 81 opens as a split U-shaped board. Two short towers rise on the left and right, then the bottom closes into a long mixed base with green and yellow pieces stretched across it. The middle is narrow, so the base is wide but the real movement still passes through one central neck.
Goal: The real target is the middle neck where the two side towers feed into the long base. If that connection stays crowded, the towers never become true routes and the bottom bar just absorbs clutter.
Opening: The walkthrough opens the middle neck first, then lowers one side tower so the base starts draining in an orderly way. It does not flatten the entire bottom bar before the neck is safe. The second tower comes later through the same opening.
Danger Zone: The trap is clearing too much of the base while both towers are still active. That makes the board look shorter, but the neck is still narrow enough to jam the next drop.
Mechanics: Level 81 is a U-and-neck board. The wide lower bar is not the real difficulty; the level is decided by whether the thin center can carry both towers without collapsing.
