In the game, the player controls a diver who attempts to reach an underwater treasure. In order to do this, the diver must avoid the arms of an octopus, who stretches and restracts them. When the diver reaches the treasure chest, he can take as many treasures as he wants as long as he avoids the tentacles. A point is gained for every treasure, and an extra three points are rewarded if the diver makes it back to the boat safely, so he can dive again. The player gets three lives, and gains a new life at 200 and 500 points.
