Why is the right column so important in Bus Traffic Fever! Level 274?

Because the loop returns through the center knot. The right column is one of the only clean sources for the later pink and blue sections.

When should I use the two green buses in the middle on Level 274?

Use them after the top layer has thinned and the loop is already feeding the central green pocket, not during the opening peel.

Bus Traffic Fever! Level 274 Walkthrough

medium 9 colors

Bus Traffic Fever! Level 274 is a loop-return board built on a tilted capsule stack. Peel the top and side layers first, keep the right blue-pink spine intact, and spend that reserve only when the knotted lane rotates back through its center crossing.

Board Notes

Layout: The floor forms a tilted capsule pile. The right edge is a vertical spine of red, pink, and blue buses, the left wing fans out with cyan, orange, purple, and brown pieces, and two bright green buses sit low in the middle.
Goal: Feed the early yellow-brown-orange-red loop while protecting enough of the right spine for the later pink-blue return through the knot. The board only stays smooth if both halves keep some reserve.
Opening: The video starts from the upper and right edges, shaving the top warm colors and the loose side pieces before touching the lower-middle greens or the bottom of the right column.
Danger Zone: Breaking the lower half of the right vertical spine too early removes the clean pink-blue answers that the loop needs once it comes back through the center crossing.
Mechanics: Level 274 is a return-loop puzzle. Colors disappear around one side of the lane and then revisit the central knot, so the floor has to preserve timing pieces for the second pass.

Quick Tips for Bus Traffic Fever! Level 274 (spoiler-free)

The right blue-pink column is stored fuel for the second half of the loop.
With 9 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

How to Solve Bus Traffic Fever! Level 274 — Full Solution

Start with the accessible top-right warm colors and the loose side buses around the upper half of the stack.
Keep trimming the outer ring, especially the cyan and orange buses on the left wing, without breaking the lower blue-pink section of the right spine.
Use the two green buses in the lower middle only after the top layer has thinned and the lane begins feeding through the green pocket in the center.
When the loop swings back into cyan, pink, and blue, cash in the saved buses from the right vertical column to keep the center crossing moving.
Clear the final scattered singles from the left wing after the spine collapses and the board no longer depends on color reserves.

Colors in this level:

Blue, Brown, Cyan, Green, Orange, Pink, Purple, Red, Yellow

Common Mistakes to Avoid

Spending the lower blue-pink part of the right spine during the opening peel.
Touching the lower-middle greens before the upper shell and side wing have loosened.
