Tips for success
- Track Mystery Tiles: Vehicles beneath question mark blocks cannot be seen until the vehicles on top move. Clear outer layers first to open up multiple routes.
- Prioritize Large Buses: Long buses require significantly more passengers to fill. Ensure you deploy them early when their color dominates the passenger queue to avoid clogging parking slots.
- Manage Parking Slots: Keep at least two slots open whenever possible so you can reposition blocking buses without causing a gridlock.
