Slot game Great Blue is a high quality online video slot game powered by Playtech. The game itself has an underwater theme and includes images of various aquatic animals frolicking around in their natural habitat. The backdrop to the game is a view of the vast empty ocean with bubbles rising up behind the reels. The graphics and animation give the game the game an extra dimension with each symbol becoming animated when used in a winning combination. In the background, the sound of bubbles can be heard with a flurry of music whenever the reels slide into position.
5 Reel Underwater Themed Slot
When it comes to the slot setup, Great Blue utilises the now standard slot setup of 5 spinning reels with 25 paylines in which players can form a winning combination. On the reels, players will find a host of aquatic creatures in all shapes and sizes. The highest paying symbols in this game include the shark, the turtle, the seahorse, the starfish and the angelfish. For the lower paying symbols, Playtech have used the high card symbols from nine to ace. The high card symbols have been designed to blend into the underwater theme of the game.
Killer Whale Wild Symbol
In addition to the standard slot machine, slot game Great Blue also includes a number of bonus features in the form of a wild symbol, multipliers, free spins and a gamble feature. The wild symbol in this game is the killer whale. The wild symbol can be used to substitute for any of the other standard reel symbols in order to create a winning mixture. The only symbol the wild symbol cannot substitute for is the pearl scatter symbol. When a wild symbol is used to form a winning combination, it will automatically double the winning amount.
Free Spins with Multipliers
The wild symbol in Great Blue is also the highest paying symbol of the game. If players are lucky enough to land all 5 killer whale wild symbols across the reels, they will trigger the slot jackpot of 10 000 coins.
