Great Reef is an adventure themed slot machine game that is filled with all manner of aquatic life forms. Learn some of the animals that live around the great reefs of this planet earth. The graphic is amazing, the reels are transparent and you can see the coral reefs are the bottom of the screen while bubbles lift off towards the surface of the water. The water sound effects make you feel like you are right here in the sea.

The animals of the sea are the high paying symbols, they include a shark, tortoise, clown fish, seahorse and starfish. The predator of the sea is the highest paying symbol amongst all the symbols, as it offers 25x your bet for a five of a kind. The card symbols A, K, Q, J and 10 are the low paying symbols. All symbols pay from right to left and the Great Reef game has a return to the player rate of 96.64%.


The fisherman/captain with his tobacco pipe is the Wild symbol and he substitutes for all other symbols except for the Scatter symbol.


The open oyster is the Scatter symbol and triggers the Free Spins feature.

Once the Free Spin mode is activated, you become a pearl hunter with the option to choose 2 out of 5 oysters, each holds either Free Spins or Multipliers, so you can never go wrong with a pick.
