Tips for success

• Watch the double-bend queue: Because passenger queues wind from both sides, monitor which color reaches the front gate next before sending a vehicle into the bay.
• Keep bottom bays cycling: Avoid parking large buses without matching passengers early on; buses take longer to clear and take up valuable buffer space.
• Prioritize corner unblocks: Unblocking the bottom-left and bottom-right corners early creates vital clearance corridors for the tightly packed center vehicles.
