In Deep Blue Sea , players take on the role of a diver who is collecting
treasure. As the diver gathers treasure, she discovers the secret of Avalonia
and its people. She soon finds Amulets that reveal more of the story.

Players make matches of three sea creatures to get treasures and the deep sea
diver to the bottom. Additionally, they can match shiny objects, such as
silverware or coins, to receive money for buying upgrades or power-ups. Pieces
of amulets can also be collected; when all the pieces of an amulet are
assembled, the completed amulet gives players additional power-ups. Amulets
can only be used when they are fully charged; to charge amulets, sea creatures
corresponding to their amulet must be matched.
