This is a great free iPad game that is FREE. Terrific color, graphics and game play. You draw lines to direct your boat to the cargo area to load up with cargo and then draw a line again to direct it to the unloading dock. Sounds easy...but it's not! You will have more than one boat and they are going in all kinds of directions. Some go faster than others and you must keep track of which are loading or unloading cargo. It is a very challenging game.
