Drag from a ship to draw its route across the lake.
Each ship carries 4 randomly coloured containers. Steer it into an island to unload every container that matches the warehouse colour, then send it on to the next island.
Empty ships go back to the port on the left to be refilled.
1 point per container. You have 60 seconds.
Watch out for sailing boats drifting across the lake. A ! shows where one is about to appear.
Hitting another ship, a boat or a rock wrecks your ship. You have 3 lives. Lose them all and you're out!
