Protect one open slot and send the color pair the queue is asking for. Once you never let a wrong-color bus park in the last slot, every other move plans itself.

Bus Traffic Fever Level 4 Guide: The Paired Buses

Level 4 pairs the buses by color. Identify the two matching buses before you move, keep a slot open for them, and never park the wrong color across it no matter how safe it looks.

The Paired Buses in Level 4

A level where buses of the same color sit in pairs and the queue feeds them one at a time. If you park the wrong color in the last open slot, the matching pair has nowhere to go.

Step-by-Step Walkthrough

First Moves: Spot the Color Pairs

  1. Find the buses that share a color.
  2. Read which color the queue is feeding first.
  3. Dispatch that pair's first bus while a slot stays open.

Midgame: Keep a Slot Open

  1. Mid-solve, stop and count the open slots.
  2. Confirm the last open slot has not taken the wrong color.
  3. Clear the one wrong-color bus threatening it before any other dispatch.

Finishing: Clear the Pair

  1. After every dispatch, check that one slot is still open.
  2. Refuse any move that would park a mismatched bus in it.
  3. Finish only when the last pair boards without closing the slot.
