Why should I open the crossing point in the middle of the X first in Bus Rush Fever! Level 77?

While that center stays shared, the side posts never gain a real lane and the square frame keeps routing traffic back into the same knot. Turn the junction into one lane and the frame cooperates.

What usually recloses the crossing point in the middle of the X in Bus Rush Fever! Level 77?

Waking both diagonals together. With two routes claiming the junction, clearing the frame only makes the box smaller around an unsolved X.

Bus Rush Fever! Level 77 clears best when you simplify one diagonal of the X, claim the crossing point, and then use the side frame to support that same lane. Open the junction first and the box around it finally starts cooperating.

Board Notes

Layout: Level 77 opens like a square frame with an X-shaped crossing inside it. Vertical side posts line the left and right edges, a colorful diagonal cross meets in the middle, and a small brown arch sits above the center. The whole lower field is dense but highly structured.
Goal: The first target is the crossing point in the middle of the X. If that center stays shared, the side posts never gain a true lane and the square frame keeps routing traffic back into the same knot.
Opening: The walkthrough simplifies one diagonal of the X first and leaves the other mostly intact until the crossing clears. It uses the side posts as support rather than as the main opening. Only after the center is calmer does the second diagonal come into play.
Danger Zone: The trap is activating both diagonals at once. When the crossing still belongs to two routes, every follow-up move makes the square look smaller without actually solving the X.
Mechanics: Level 77 is a crossing-frame board. The outer square matters, but only because it contains a live X junction that has to be turned into one lane before the sides become useful.

Quick Tips for Bus Rush Fever! Level 77 (spoiler-free)

In Level 77, the X is the puzzle and the square is just the container. If the crossing is shared, nothing else is solved.
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 77 — Full Solution

Reduce one diagonal of the X first so the center crossing stops serving two routes.
Keep the opposite diagonal quiet until the middle has become a single lane.
Use the side posts only to reinforce the crossing you already opened.
Bring the second diagonal into the center after the first arm has fully cleared through it.
Finish by collapsing the remaining frame pieces into the now-safe middle junction.

Common Mistakes to Avoid

Activating both diagonals at once, so the crossing still belongs to two routes and every follow-up move shrinks the square without ever solving the X.
