Solution summary
Quick Answer
Start with the exposed green and pink buses on the left, use cyan buses from the outer columns, and hold the yellow and brown center buses until those passenger colors reach the entrance. Finish with one bay open.
Overall Strategy
Level 4 expands the vehicle grid and introduces more color changes. The safe route works from the exposed outside buses inward while preserving access to the yellow and brown buses in the center.
Do not treat the five bays as permission to queue five colors. Keep one bay empty so the next required color can enter when the passenger loop changes.
Starting Board
The rectangular vehicle grid contains cyan buses on both outer columns, green buses through the left and center, pink vertical buses, yellow buses around the middle, and brown buses near the top and bottom rows.
Step-by-Step Solution
Step 1
Open the left side with green and pink
Tap the exposed green bus on the left edge, then the nearby pink vertical bus when pink reaches the entrance. This removes the first blockers without sealing the center lanes.
Step 2
Use cyan buses from the outer columns
Send cyan buses from the left and right edges as the cyan groups arrive. Work downward along the outside of the grid and leave the yellow center bus parked.
Step 3
Release yellow and brown, then clean the center
Tap the yellow and brown buses only when their matching passengers control the entrance. Finish with the remaining green, cyan, and pink buses exposed through the center.
Before Each Move
- The next center bus will remain reachable.
- At least one loading bay is empty.
- The selected outer bus matches the entrance.
- Yellow and brown stay parked until needed.
Where Players Get Stuck
The difficult point is the first large cyan group. Sending every visible cyan bus fills the bays before yellow or brown can enter. Use only the cyan buses needed for the current group, then change colors with the loop.
