Bus Traffic Fever Level 21 Guide: The Conveyor Warm-Up
Level 21 reintroduces the conveyor after a long stretch of parked boards. Find the conveyor's rhythm, tap each bus on that rhythm, and let the conveyor hand you the win one vehicle at a time.
The Conveyor Warm-Up in Level 21
A re-entry board where the buses glide in on a conveyor rather than sitting still. The puzzle is timing — the conveyor has a rhythm, and your taps either land on it or break the flow.
Step-by-Step Walkthrough
Ride the conveyor, don't chase it. The level is a rhythm problem: release every bus on the conveyor's rhythm and the board empties itself.
First Moves: Feeling the Conveyor's Rhythm
- Watch the conveyor run a full cycle before you touch anything.
- Count the rhythm as the first bus reaches the pickup point.
- Release the first bus only when the conveyor and your tap line up.
Midgame: Releasing on the Rhythm
- Keep the same rhythm through the middle buses.
- Do not rush a tap when the conveyor briefly speeds up.
- Let each bus clear the lane before the next rhythm.
Finishing: Holding the Rhythm Home
- Hold the rhythm steady for the final buses.
- Release the last bus on the same rhythm as the first.
- Confirm the conveyor is empty and the lane is clear.
