Why does Bus Rush Fever! Level 123 take so long despite looking simple?

Its colors are heavily interleaved and the loop seats them slowly, so the solve is paced by a slow passenger cycle rather than by clearing a dense jam.

What is the key to not jamming Bus Rush Fever! Level 123?

Patience. Send only what the loop is ready for, wait out each cycle, and keep a slot in reserve so an early, mistimed dispatch does not clog the row for the rest of the run.

Bus Rush Fever! Level 123 Walkthrough

hard 7 colors

Bus Rush Fever! Level 123 looks like a routine scatter but runs long because its colors are interleaved and the loop seats them slowly. Send only what the loop is ready for, wait out the cycle, and the board clears without ever jamming.

Board Notes

Layout: Level 123 opens as a medium scatter that looks ordinary but plays long. Blue, purple, red, orange, green, and pink buses are spread across the lot with brown buses gathered lower down, and the colors are heavily interleaved rather than grouped.
Goal: The real target is the color order over a long solve. Because the colors are interleaved and the loop seats them slowly, the puzzle is patience, matching each dispatch to a passenger cycle that takes its time.
Opening: The walkthrough sends whatever color the loop is currently ready for, then waits out the cycle rather than forcing the next bus. It treats the board as a long sequence, not a quick clear.
Danger Zone: The danger is impatience. The interleaved colors tempt you to push buses before their passengers come back around, and a few early dispatches clog the slots for the rest of the run.
Mechanics: Level 123 is a long interleaved scatter. The layout is not dense, but the slow passenger cycle and mixed colors make it one of the longer solves of this band.
