Bus Rush Fever! Level 57 Walkthrough

hard 4 colors

Bus Rush Fever! Level 57 clears fastest when you commit to the center-right opening, remove the black diagonal there, and keep the rest of the ring quiet until that pocket is stable. The board is not about making the hole larger; it is about deciding which edge of the hole will survive the next route.

Board Notes

Layout: Level 57 opens as a hollow diamond or donut. Colored buses wrap around an empty center, with a black diagonal chain cutting across the middle-right and loose brown and green singles sitting above the ring. The lower half is fuller than the top, so the central pocket feels open but fragile.
Goal: The real target is the ring opening on the center-right where the black diagonal crosses the hollow middle. Until that lane is simplified, the donut shape never becomes a route and the empty center stays decorative.
Opening: The solution begins by reducing the center-right side of the ring and peeling away the black diagonal before spending the outer pink and green curves. It leaves most of the opposite side intact so the board keeps one dependable pocket instead of several weak ones.
Danger Zone: The trap is opening both halves of the donut at the same time. If the left and right sides both start feeding toward the hollow center while the black diagonal still survives, the middle pocket closes and the board turns into scattered leftovers.
Mechanics: Level 57 is a true donut board. The empty center tempts you to treat every edge as usable, but only one side of the ring actually becomes a durable lane.

How to Solve Bus Rush Fever! Level 57 — Full Solution

Open the center-right edge of the ring first and attack the black diagonal that cuts through it.
Keep the opposite half of the donut mostly untouched until the chosen opening is clearly stable.
Use the new pocket to run one color through the ring instead of waking both sides at once.
Bring down the loose top singles only when they help the chosen lane stay open.
