Fill one lane with a single colour to send it to its ship.
Welcome to the yard
You cannot drop containers straight onto a ship. Gather a whole load of the same colour into one lane and it sails by itself.
Step 1
You always pick up the top of a stack - and every container of the same colour that is sitting right under it comes along.
Step 2
Drop them on an empty lane or on top of their own colour. Complete a lane and the ship leaves. Stuck? Undo is free and always available.
