Bus Rush Fever! Level 78 Walkthrough

medium 5 colors

Bus Rush Fever! Level 78 is solved by breaking the black middle band first and preserving the small lower gate underneath it. Once that strip splits, the colorful upper rows stop acting like a roof and start draining in order.

Board Notes

Layout: Level 78 opens as a squat fortress with a thick black horizontal band across the middle-lower rows. Above that band are compact red, purple, cyan, and green stacks, and below it sits a small bottom gate of cyan and green buses. The black strip is the obvious spine of the board.
Goal: The real target is the black band and the narrow gate under it. The colorful rows above look busy, but the fortress only opens when that dark middle strip is broken and the lower gate can breathe.
Opening: The walkthrough uses the easiest upper clears to expose the black band, then starts splitting that strip instead of polishing the colorful roof. It keeps the bottom gate available so the first breach has depth. Only after the band weakens do the upper rows begin to fall cleanly.
Danger Zone: The danger is over-clearing the top colors while the black strip remains intact. That makes the board look smaller, but the next drop still lands on the same dark wall and blocks the lower gate again.
Mechanics: Level 78 is a black-band fortress board. One dark horizontal layer holds the whole structure together, so the correct solve is about cutting the belt, not decorating the upper rows.

Quick Tips for Bus Rush Fever! Level 78 (spoiler-free)

In Level 78, the black band is the board. If it is still intact, the fortress is still standing.
With 5 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

How to Solve Bus Rush Fever! Level 78 — Full Solution

Use the easiest upper moves to expose the black middle band instead of clearing the whole top layer.
Split the black strip early so the fortress loses its strongest horizontal brace.
Keep the lower cyan-green gate open so the breach has somewhere real to drain.
Let the upper rows fall only after the band is no longer able to reconnect the middle.
Finish by clearing the remaining colorful roof through the cut you already made in the dark belt.

Common Mistakes to Avoid

Over-clearing the top colors while the black strip is still intact, so the board looks smaller but the next drop lands on the same dark wall and reseals the lower gate.
