Why should I clear the outer diagonal buses before using the wheel in Bus Rush Fever! Level 15?

Those edge buses create the first stable lane into the center-left knot. If you start spending wheel colors first, two wedges queue over the same pickup strip and neither finishes cleanly.

What usually breaks the route order in Bus Rush Fever! Level 15?

The run falls apart when you keep the crisscross too wide and then swap to a second top color before the first wedge has finished. This board rewards one complete safe chain at a time.

Bus Rush Fever! Level 15 Walkthrough

expert 9 colors

Bus Rush Fever! Level 15 is solved by cutting down the diagonal field before the wheel gets to run wild. Clear the easiest outer buses, open the center-left knot, and then drain the safest top colors one full chain at a time.

Board Notes

Layout: Level 15 opens on a large mixed-color field with buses scattered in diagonal bands below a busy wheel. The top route carries bright lime, teal, pink, yellow, and purple wedges, while the lower buses sit in a loose crisscross that creates several fake openings but very few stable lanes.
Goal: The board clears only after that crisscross field is reduced enough that the wheel can unload one color chain at a time. The real target is the center-left traffic knot, because that is the area that keeps the top wedges from finishing cleanly.
Opening: The walkthrough starts by removing the easiest buses from the outside of the diagonal field and then cashes a clean top color while the middle is still open. That opening uses field cleanup and wheel progress together instead of trying to solve only one half first.
Danger Zone: The danger point comes when the diagonal field is only partly reduced and two bright top wedges are both lined up above the same pickup strip. If you keep the crisscross too wide for too long, the next wedge arrives before the previous color has actually cleared a landing zone.
Mechanics: Level 15 is a whole-field traffic board. It is not about one stack or one column anymore; it is about shrinking a diagonal spread until the wheel finally behaves in a controlled order.

Quick Tips for Bus Rush Fever! Level 15 (spoiler-free)

Level 15 looks chaotic because the lower field is wide. Shrink that width first and the wheel becomes much easier to read.
With 9 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Bus Rush Fever! Level 15 — Full Solution

Start with the outer buses that reduce the widest part of the diagonal field without adding fresh clutter to the middle.
Use that first space gain to open the center-left knot instead of bouncing between several unfinished colors.
Once one wedge from the top wheel has a safe lane, follow that color through completely while the strip is clean.
Return to the lower diagonal field whenever it starts widening back into the center again.
Finish the remaining wheel colors only after the lower spread has collapsed into a much smaller cleanup zone.

Colors in this level:

Common Mistakes to Avoid

Letting the diagonal crisscross stay wide while you alternate between two half-cleared wheel colors instead of finishing one clean wedge first.
