Before starting, inspect the complete warehouse queue and all vehicle capacities. Tap junction arrows or their numbered buttons below the map, including while parcels move. Match each parcel symbol and colour to its destination. Vehicles leave when their loading plan is complete; every load capacity is shown in advance. The dock is empty between loads. A fall or wrong delivery damages the parcel and sends it to the queue tail. A second error for the same parcel ends the attempt. Damaged parcels can still be delivered successfully. Drag to pan; pinch or use +/− to zoom. Every level has a verified solution and the same initial queue for all players.
