Why is one side break better than chipping all four edges of the square ring in Bus Rush Fever! Level 20?

One breach turns the hollow square into a usable lane through the middle. Small cracks on every side still leave the center boxed in when the next top chain arrives.

What usually traps the middle again in Bus Rush Fever! Level 20?

Players often open the ring once and then switch to a different edge instead of widening the same breach. Keep working the first opening until the inner edge stops pushing buses back into the center.

Bus Rush Fever! Level 20 Walkthrough

expert 7 colors

Bus Rush Fever! Level 20 is solved by breaking the lower square ring early. Open one side, cash the first safe top route through the breach, and then keep widening that opening until the ring can no longer trap the center.

Board Notes

Layout: Level 20 opens with a chunky square ring of buses in the lower half and a wheel that leans heavily on yellow, cyan, and pink chains. The lower field is more structured than Level 19, but the pieces still wrap around a hollow center that can clog quickly.
Goal: The board clears when the square ring stops feeding buses back into its own center. The true target is the inside edge of that ring, because that is where the next top chain either finds space or runs into a wall of unfinished cleanup.
Opening: The walkthrough begins by breaking one side of the square ring and then using the breach to send a top color through the center before the gap closes. That first break is the move that turns the ring into a workable route instead of a self-contained jam.
Danger Zone: The danger comes when the lower square is only partly broken and the next top chain arrives over the same inner edge. If you leave the ring too intact, the center keeps bouncing colors back out instead of accepting them cleanly.
Mechanics: Level 20 is a ring-break puzzle. The lower field is not just clutter; it is a structure that has to be opened on one side before the wheel can use the middle effectively.

Quick Tips for Bus Rush Fever! Level 20 (spoiler-free)

Level 20 gets much easier once you commit to one break in the ring. One real opening beats four partial ones.

How to Solve Bus Rush Fever! Level 20 — Full Solution

Break the easiest side of the lower square ring first so the center stops being sealed on all four sides.
Use that first breach immediately on a top color that now has a straight line into the middle.
Keep widening the same opening instead of creating several shallow cracks around the ring.
Only bring another top chain down after the inner edge is open enough to absorb it cleanly.
Finish the board by turning the former square ring into a simple cleanup lane with no closed center left.

Common Mistakes to Avoid

Opening one side of the square ring and then abandoning that breach before the inner edge is wide enough to absorb the next top chain.
