Bus Rush Fever! Level 143 Walkthrough

medium 7 colors

Bus Rush Fever! Level 143 rings a cluster of black buses with colored traffic. Clear the colored ring first, then lift the central black buses off one at a time as slots open, and the middle unchokes without sealing the lanes.

Board Notes

Layout: Level 143 opens as a scatter with black buses gathered in the center. Green, blue, orange, yellow, purple, and pink buses ring the outside, while several black buses cluster through the middle of the board rather than spreading evenly.
Goal: The real target is the black cluster in the center. Because the black buses bunch in the middle, they choke the lanes that the surrounding colors need to reach the exit.
Opening: The walkthrough clears the colored buses around the edge that already have passengers, then lifts the central black buses off one at a time as slots open. It works inward toward the black core.
Danger Zone: The danger is letting the central black cluster pile into the slots. Bunched in the middle, two black buses freed together can seal the lanes for the whole ring of colors around them.
Mechanics: Level 143 is a center-clustered black board. Unlike the evenly threaded black boards, here the obstacles bunch in the middle, so the solve works from the colored ring inward.
