Why should I open the crossing point of the X first in Bus Rush Fever! Level 84?

If that junction never opens, the diagonals stay decorative spokes with nowhere clean to finish. Claim the crossing and hand it the tray as a landing strip, and the symmetry stops being dangerous.

What usually clogs the crossing point of the X in Bus Rush Fever! Level 84?

Lighting up all four arms at once. With the tray still shallow, the crossing has no exit and every diagonal wants the same one.

Bus Rush Fever! Level 84 is solved by opening one arm of the X, claiming the center crossing, and feeding it into the small tray below before the other arms join in. Once the junction has one safe exit, the symmetry stops being dangerous.

Board Notes

Layout: Level 84 opens as a large X over a short lower tray. Four diagonal arms cross in the middle, while a blue-green-yellow bar sits beneath them like a small base. The diagonals are bright and symmetrical, but the lower tray is much shorter and easier to choke.
Goal: The first target is the crossing point of the X and the tray immediately below it. If that junction never opens, the diagonals remain decorative spokes with nowhere clean to finish.
Opening: The walkthrough simplifies one arm of the X first and uses the lower tray to absorb that route. It does not wake every diagonal together. The second side only enters after the center crossing clearly belongs to the first route.
Danger Zone: The danger is activating the upper diagonals while the lower tray is still too shallow. That turns the crossing into a jam where four arms want the same exit.
Mechanics: Level 84 is an X-and-tray board. The solve is about turning the crossing into one controlled lane and giving it a real landing strip underneath.

Quick Tips for Bus Rush Fever! Level 84 (spoiler-free)

In Level 84, the tray under the X matters more than it looks. Without it, the center has nowhere safe to empty.
Focus on one color at a time: finish the cleanest grouping, then reassess the whole board before the next move.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

How to Solve Bus Rush Fever! Level 84 — Full Solution

Simplify one diagonal arm first so the crossing point stops serving every branch at once.
Use the lower tray to hold that first route instead of treating it as late cleanup.
Keep the opposite diagonals quiet until the center has become a stable lane.
Bring the next arm into the crossing only after the tray has cleared the previous traffic.
Finish by draining the remaining diagonals through the junction you already stabilized.

Common Mistakes to Avoid

Waking the upper diagonals while the lower tray is still too shallow, which turns the crossing into a jam where four arms fight for the same exit.
