Stackport: Harbor Puzzle

Send the right ship at the right time.

The yard is stacked with colored containers. Ships wait in their queues. Tap a queue and its front ship sails the canal round the yard, loading every matching container it can reach. A full ship leaves. A ship with room left waits at a berth, and when every berth is full, the level is lost. So look before you tap: which ship fills up in one loop?

• 50 levels across five harbor zones
• Containers stacked in layers: clear the top to reach the colors below
• New tricks arrive slowly: tarps that hide colors, locked ships and keys, convoys roped together, ice, and a storm clock
• Hard and very hard levels that reward planning, not speed
• Earn coins, spend them on boosters, and build your own harbor piece by piece
