Sunken Treasure is a 5 reel, 20 payline slot machine game with an underwater theme. It works just like a real slot machine game. You can't win any real money, but you can win plenty of virtual money to impress everyone. Like the pokies? You'll love this game.But wait, there's more! If you get three or more scattered Treasure Chests (these symbols can appear anywhere, they don't have to appear in a row) you win the Treasure Feature!
