Stapele Container, erfülle Lieferaufträge und halte den Hafen frei.
Block Harbor is a compact stacking puzzle where every container changes the shape of the next move. Build stable space for deliveries instead of chasing a single large stack.
Place containers to fulfil the active delivery goals without blocking the harbor. Use the visible controls to choose a position, then keep enough open space for the next shipment.
Leave a flexible edge in the stack; it is usually more valuable than one extra completed column.
