Bus Traffic Fever Level 173 Answer & Walkthrough Solution

Quick answer

Level 173 features a heart-shaped traffic arrangement beneath a triangular track with dual countdown barrier gates (starting at 80). The key is peeling off outer vehicles to rapidly reduce gate counters, then systematically dismantling the rotating center vehicles by coordinating their release with the alternating colors arriving on both sides of the passenger track.

Step-by-step solution

Phase 1: Opening the Outer Flanks & Releasing the Gates

1. Tap the Green bus on the far-left outer edge pointing down and left. Green passengers will board immediately, reducing the left gate counter.
2. Tap the angled Orange bus in the upper-left quadrant pointing up and left into an open slot to load the orange line.
3. Tap the Cyan bus in the upper-middle area pointing up and right to board arriving cyan passengers.
4. Tap the Red bus on the lower-left flank pointing down and left.
5. Tap the small Red bus pointing up and left right behind it. Red passengers will fill both vehicles and clear their slots.

Phase 3: Untangling Mid-Level Traffic (Yellow, Pink, Brown, Blue)

13. Tap the Yellow bus in the center pointing left to load incoming yellow passengers.
14. Tap the Pink bus on the lower-right flank pointing down and left.
15. Tap the large Brown bus on the lower-left pointing down and left to board brown passengers.

Tips for success

• Monitor the Dual Gate Countdowns: Both candy-cane striped gates require 80 passengers to pass before opening the outer loops. Prioritize matching vehicles from the active side to drop the gate counter to 0 as quickly as possible.
• Unlock the Center from the Corners: The central core vehicles are boxed in by the angled perimeter buses. Peeling off the outer diagonal buses creates exit runways for the inner vehicles.
• Don’t Rush the Center Rotators: Vehicles with turning indicators in the middle will only have safe escape angles once their adjacent neighbors are cleared. Keep parking slots open so you don’t stall the board.
