Treasure reef Blackberry Game for OS 4.0 or greater. Rumor has it that a pirate ship sank out on Treasure Reef holding ten giant pearls and a mystery treasure. Fact is nobody has ever made it back to tell. Between the rocks, rip tides, stingrays, and sharks there isn't a lot of leeway for wrong moves. Correction: make that no leeway at all.
Drive your watercraft on the map looking for likely spots to dive. When you find one the game will switch to a diving view. Dive down looking for pearls. Feel free to use your spear gun -- no fish were injured in the production of this video game. When you find a pearl return it to your watercraft. Keep searching the map until you find all ten pearls and win the game or, well, die.
