In the game, your task is to move around the ship, fetching goods from the sea and bringing them back to the home port. Movement is done using mathematical operations, but be careful not to bump into islands or pirates! By playing maps that develop adaptive number awareness, you earn resources with which you can build buildings on your own island. At first the island is completely empty, but by playing hard you can first create your own little village there and eventually turn it into a beautiful city.
