Great Blue

Are you looking for the popular Playtech Great Blue slot machine?

Great Blue is an “Under Sea” slot that’s full of bright colours and sounds and easy on the eye graphics- a real mood lifter; you can go from calm to crazy with just the click of a reel!

What’s not to like about diving into a slot game that the equivalent of jumping into a warm ocean? I’m right in!

Playtech’s Great Blue is one for those games for those who want to kick back and watch the aquatic world sail by, until the action gets underway that it! Just wait for Great Blue to give your wallet a welcome boost too in this under the sea game of luck and daring.
Let’s face it, the underwater world is a theme that slot lovers have seen before but with games like the Ariana slot machine and Mermaids Millions, hitting this same rich seam, the ocean world is a great place to undercover slot treasure and come out with your pockets stuffed with gold.

Despite its calm exterior it has to be said that Great Blue is a high variance game like the Marilyn Monroe Slot. These games have been built to thrill which means that things can go pretty crazy every so often, although you also might also run into some lean periods, so buckle up for the unknown exploration ahead! You are going into the unknown.

The Great Blue Slot Run Down

Playtech’s Great Blue is all about the massive orca whale of the game’s title and unlike Black and White Giant, this slot packs a punch with a whopping bonus feature and stacked Wilds to keep the action coming as long as you can keep those reels spinning.

While a blue suffused world may connect to our inner cosy place, this cool package of a slot actually offers up some high volatility game play, which fans of games like the Diamond Queen slot will already know and like. Just make sure you’ve got your bank roll ready for an adventure, it won’t be just plain sailing – for the brave sailor it could land you with a whole heap of treasure!

The background to this fishy tale is quite naturally the blue ocean with bubbles continually rising in the background, that’s the soothing bit. The reels are a transparent affair and here you will encounter a whole ecosystem of sea creatures which will appear on the reels to make us a buck or hopefully mega bucks!

The background music to play is upbeat and a bit bleepy but otherwise its high energy vibe matches the high volatility nature of the game play beneath the waves and it doesn’t distract from the game play.

Game play

Great Blue is a 5 reel, 3 rows and 25 pay lines aquatic slot adventure where risky times and rewards are promised ahead.
The high value animals that inhabit the reels are a turtle, shark, seahorse and star fish and these fishy dudes are accompanied by the lower value icons of play, the Ace through nine of the card deck done up in, you guessed it, blue!

he game’s Wild is the ocean-going behemoth, the Great Blue orca of the slot’s title, and he’s a kindly creature. Who knew that an orca could stack to cover an entire reel, making for more winning combos for you? And that’s not all, when the orca is part of your winning combo he also doubles your win! He’s more cash cow than killer whale!

The Wild symbol subs for all icons except the Scatter which is an oyster containing a mega pearl- the ocean is so good to us!

Blue bonanza

The slot’s feature is triggered by luring three or more of the oyster Scatters onto the reels and this bonanza begins by gifting you a welcome eight free spins with a x 2 multiplier in play. But there’s more money making fun to be had before you even get to spin a reel.
First up you’ll get a new screen where you will play a picking game. Here you choose to open two out of the five oysters on display.

These secretive shells contain some generous treasure worth revealing with a cracking x15 multiplier hiding in their midst, as well as a satisfying 33 free spins just waiting for you to ping open its secret. This is a high variance slot like the Isis Slot– make no bones about it!

Also, the Great Blue stacked wild also comes into play in the free spins round, so your theoretical maximum win from the free spins is around 100x or more. Now that’s what we call treasures of the deep!

And if you like to take your game to the next level in volatility there’s a gamble feature to boot!


This is one of the best games to come out of Playtech since their Marvel blockbuster slots like the Incredible Hulk slot and IronMan II.
But, don’t forget despite its chilled vibe Great Blue is still a medium to high variance slot. What does this mean? Well, it can take over 500 spins to hit the free games bonus, and if you are playing maximum bet, that can get very expensive!

If you like a medium to high variance slot, you can also try Cashapillar from Microgaming- the graphics aren´t quite as “whizzy”, but the max bet is lower and it’s also a good solid slot game. This is a quirky, fun and rewarding game that is easy on the eye but you need your wits about you and the energy and payroll to be prepared to hunker down, it might take its time coming but when Great Blue blows and it pays out, it pays out in the only way a massive beast can, it goes mega!
