About Great Blue

Regardless of whether the summer season is in full swing or you're freezing in winter, Great Blue from Playtech is sure to have plenty to keep you entertained. This 5 reel, 25 payline game features a bunch of friendly, aquatic critters in addition to a wild symbol, a free spins bonus, and a gamble bonus. It has more than enough to make you go under the sea!

Great Blue information

When you hear Great Blue, you might conjure up images of your head of a vast, merciless body of water full of fearsome creatures ready to eat you alive. That is not what this Great Blue is all about. Rather, it portrays the underwater world as a friendly place full of beautiful, fun critters. Indeed, this is a clear, beautiful body sea full of turtles, starfish, seahorses and whales.

In addition to the exquisite, easygoing presentation, Great Blue has a number of bonuses to keep you entertained under the surface of the water: The first of these is the impressive free spins bonus, which is activated by having three or more shells with pearls come up anywhere on the reels. Pick two out of the five seashells to win up to an incredible 33 free spins and an amazing 15x multiplier.

I started to play this one just because i have heard that it pays great. But my first sessions weren't successful.
I was losing and losing. But one time i have got for rows of sharks and really won big. That was my first time when i found it well paying:)
Next great session was when i hit 4 free spins rounds in one hour. It didnt pay very huge but i lifted my bankroll very good and despite didnt much of luck during free spins. But now i know that this game can do a lot:)
One of the bet games from Playtech in my view.

I like Great Blue very much with Gladiator in Playtech slots.

Probably, Great Blue is one of the games that can give the highest wins.
As I know, some Playtech casinos set the max bet up to $10 only, which can still give a huge amount with up to 15 x multiplier.

I hope that I will win a big shot in this game soon 🙂

Great Blue is a really a great slot, I really like this slot and play it regularly. I have rarely lost while playing this slot. with the 15 free spins bonus you always have to hope to win big.
