Bus Traffic Fever Level 251 Answer & Walkthrough Solution
Quick answer
To beat Level 251, systematically clear the unblocked outer vehicles to match the incoming passenger line (starting with Red, Green, and Purple), which gradually frees up the tightly packed center and reveals the black mystery vehicles. Always ensure you do not fill all parking bays with dormant buses so active passengers can continuously board and depart.

Step-by-step solution
Phase 1: Clearing the Outer Vehicles
- Tap the Green bus at the lower-left edge pointing up-left to move it into a parking slot.
- Tap the Red bus on the upper-right edge pointing right. The front red passengers will board immediately, allowing the bus to depart.
- Tap the Green bus on the lower-left pointing down-left. The green passengers will finish boarding the first Green bus and begin filling the second one.
- Tap the Purple bus on the middle-left pointing down-left into a parking slot. Purple passengers will board and it departs.
- Tap the Brown bus at the bottom-right edge pointing down-right into a parking bay to clear space.
Phase 2: Opening the Center and Handling Color Waves
- Tap the Red bus at the bottom-left pointing down-left.
- Tap the Orange bus at the top-right pointing up-right. Orange passengers at the front will board and clear out, followed by red passengers boarding the waiting Red bus.
- Tap the Yellow bus at the upper-left pointing up-left.
- Tap the Green bus in the middle to collect the next group of green passengers.
- Tap the Purple bus on the far left pointing up-left. Purple passengers will board and it departs.
- Tap the Yellow bus at the bottom-right pointing down-right.
- Tap the revealed Orange bus to pick up the orange passengers.
- Tap the Red bus at the lower-left pointing left. Red passengers board and it departs.
Phase 3: Revealing Mystery Vehicles and Midfield Clearing
- Tap the small Red bus in the lower section to finish off the red group.
- Tap the Yellow bus in the lower-middle pointing downward to board yellow passengers.
- Tap the Orange bus at the bottom pointing down-right.
- Tap the Cyan (light blue) bus pointing up-right. Cyan passengers will board and clear.
- Tap the Brown bus at the bottom; brown passengers will board and fill both brown vehicles, freeing parking slots.
- Tap the Purple bus at the bottom-right pointing down-right to collect purple passengers.
- Tap the Pink bus at the lower-left pointing down-left. Pink passengers board and it departs.
- Tap the second Pink bus pointing up-right to finish boarding the pink group.
Phase 4: Final Sequence and Cleanup
- Tap the revealed Cyan bus to board the next cyan passengers.
- Tap the small Pink bus pointing down-left to pick up the pink queue.
- Tap the Green bus pointing up-right to board green passengers.
- Tap the large Red bus in the center pointing up-right to collect the red group.
- Tap the large Purple bus pointing down-left to collect purple passengers.
- Tap the Pink bus pointing up-left to board pink passengers.
- Tap the Yellow bus pointing down-right to pick up the yellow passengers.
- Tap the Blue/Cyan bus to collect the blue passenger line.
- Tap the small Red bus pointing down-left to clear the remaining red passengers.
- Tap the remaining Cyan, Purple, Orange, and Pink vehicles sequentially as each matching color reaches the front of the queue.
- Finally, tap the last Yellow bus to board the final yellow passengers and complete the level.
Tips for success
- Observe the Queue: Always keep an eye on the passenger queue at the top to release vehicles matching the front-row colors and prevent bay gridlock.
- Use Slots Strategically: Storing a non-matching vehicle is fine only if it immediately unblocks a vehicle that clears the current passenger line.
- Uncover Mystery Buses: Black mystery vehicles with question marks block the core. Prioritize clearing their surrounding vehicles early to reveal their color and driving direction.
