An online slot based on the world of marine life is always a winner for us and Great Blue launched by Playtech is just that; it focuses mostly on the underwater life waves and many things about the slot looks aquatic. Bubbles constantly arise around the reels and you can just see sunlight breaking the surface behind the Great Blue logo.
This game has 5 reels and 25 pay-lines and even if the low value symbols are just playing cards, those cards bubble away when the reels spin. The higher value symbols are a variety of marine creatures such as starfish, seahorses, stripy yellow tropical fish, turtles and sharks.
Typical symbols are a blue whale wild and a pearl within a pink shell that trigger the bonus game.
This is the primary bonus feature in Great Blue and it can be a profitable one; you can activate it by dropping three or more of the pearl scatter symbols wherever on the reels. This kicks off the round and you will get 8 free spins but that is not all; the first step is to pick 2 out of 5 shells on the screen in front of you for which you will be awarded with up to 33 free spins and a 15x multiplier. You can now begin the free spins.
More spins can be achieved during this round by dropping 3 more of the scatter symbols and this can happen endlessly.
For the players amongst us (and let’s face it, most of us are) there is a lot of opportunities to gamble your last win – just click the ‘Gamble’ button at the bottom of the window screen and then pick either red or black to make your money double. If you are wrong, you will lose your money and the round is finished.
Blue Whale Stacked Wild
The blue whale wild is a stacked wild, meaning one, two or three wilds can turn up directly on top of each other; in this way, they can cover a total reel meaning that it is easier to make winning combinations. If it is involved in a winning combo it also means a 2x multiplier.
Great blue slot is rather easy game with stunning graphics and animations; we should add a mention for the cheerful soundtrack that is not particularly aquatic but that does not really matter.
