The object is to recover treasure from a sunken ship without getting caught by an octopus. The player must aim his diver under water by jumping off the side of a boat. Each time the octopus touches the player, one life is lost. A point is awarded for each portion of treasure retrieved from a sunken ship, and three additional points are awarded for evading the octopus a second time and returning to the boat. In Game B, the octopus is quicker and there are more hazards. (wikipedia.org)
