Bus Traffic Fever Level 171 Answer & Walkthrough Solution

Quick answer

Level 171 features a chaotic diagonal pinwheel pattern where vehicles overlap in multiple interlocking directions. The key to clearing this level is targeting the exterior vehicles whose tails or noses face outwards with an unobstructed path off the board, while strictly matching the fast-shifting queue on the heart-shaped passenger track to prevent slot gridlock.

Tips for success

• Mind the Slanted Trajectories: Many vehicles in this level are tilted at 45-degree angles. Ensure their diagonal escape corridor is completely unobstructed all the way to the boundary wall before tapping them.
• Alternate Between Wings: Avoid tapping exclusively from one side of the pinwheel. Clearing an outer vehicle on the left often loosens the tail of a bus crossing into the right cluster.
• Reserve Slots for High-Capacity Buses: Because several 40-capacity buses sit deep in the cluster, keep at least two adjacent parking slots empty so you can pull out blocking buses without running out of staging room.
