In a graphical sense, the free Great Blue Jackpot slot scores quite highly, and you can tell that it is a modern release. All the reels spin flawlessly and all other animations have been created to a high standard. The symbols you can expect to find on the reels consist of a range of different sea creatures such as turtles, starfish and sharks.

Great Blue is part of the 25 line range found at Playtech powered casinos. It is an action packed game with stacked wilds and has one of the highest free spin multipliers we have seen online. You can win up to 33 free spins with all wins multiplied by 15 - this makes for some giant jackpots.

However, the Playtech manufacturer is an exception, as it offers to explore the ocean in a new thematic slot called Great Blue Jackpot. This is an updated version of the familiar emulator that became very popular and bypassed all the “marine” competitors. Playtech’s Great Blue is also available as a mobile slot. You can marvel at the creatures in the ocean world on your mobile device, as the killer whale makes its journey under water, and passes by spinning marine creatures, turtles, starfish, and swims by sharks, too.

The game has an undersea theme with symbols such as sharks, turtles, fish, sea horses and whales appearing on the reels. The whale symbol is wild and appears in stacks of three. This means it is possible to get a whole screen of wild symbols which was first seen on games like 50 Lions from Aristocrat.

Max bet on great blue is 250 coins per spin so you are looking at at least $2.50 per spin if you want to play max bet. You can of course bet more and there are several coin sizes ranging from 1c to 50c.

As usual the wild symbols are the highest paying with five wild whales paying 10,000 coins multiplied by coins bet per line. With a max bet of 10 coins per line this pays 100,000 coins. The wild also doubles any win it is a part of so this makes it even more important.

The 100,000 coin jackpot alone is among the highest in this category but there is a way to win an absolutely gigantic 2,500,000 during the base game. This is because the wilds are stacked so if you get a whole screen of wild whales you win the top jackpot on all 25 lines!

The scattered shells are the ticket to even bigger winnings. Get three, four or five anywhere on the reels and you win the free spins. Once activated you move to a bonus screen where you have five shells. You get to pick two to add extra free spins or higher multipliers to the initial 8 spins with 2X wins. You can win as many as 33 free spins and multipliers as high as X15 (Screenshot).

Now the jackpots on the base game are already huge but Great Blue has set a record for a non progressive slot. If you manage to get a whole screen of stacked whales and have the highest multiplier you will win an earth shattering 37,500,000 coins. Even at the 1c coin size this is $375,000! Play at the 50c coin size and this jackpot is a life changing $18,750,000!

If the standard wins are not big enough for you Great Blue has an extra way to win with the red / black double up feature. After a win simply click the gamble button and you can try your luck at doubling up your win.

Great Blue has the biggest non progressive jackpots of any online slot game. The stacked wilds and big free spins feature make it a top pick. If you are looking for big jackpots and great features then Great Blue is hard to go past.

The Orca symbol is the wild, and just like it happens with a joker at a card game, you can use the wild as a substitute for the regular symbols apart from the scatter.

Additionally, after the symbol replaces others to form a winning combo, the resulting winnings will be doubled. The scatter symbol appears in the image of an oyster shell that is beautifully adorned with some cherries.

When several scatter features show up at the same time, you will get instant rewards. However, if you have three or more scatter symbols on sight, you will be able to activate a special feature on the game that is called the Sea Shells Bonus.

Eight free spins that are accompanied by a 2xmultiplier are initially triggered, and from here, you can be able to pick two cubes from the provided list of five. This step will boost the number of spins to as many as 33, in addition to multipliers of up to 15 xs.

Playing in line with the slot’s theme, Great Blue normal symbols borrow from the letters of the alphabet. These letters sink beneath the waves of the sea, and the sea monsters.

If you manage to form a combination using at least five wilds, you will earn jackpots worth as much as 750xs the line bet.

With Great Blue slot game, you can be able to change the amount on a bet for each spin. The least bet amount is achieved if you opt to select only a single active pay line, with the line bet set at just 0.01.

For the maximum wager, you will need to trigger all the pay lines, in addition to selecting a line wager of two. However, apart from this, there are other wagering options that you can use.

Great blue offers you a chance to explore the magical sea life, without really wetting your feet. This slot is a great development by Playtech, and only comes with a few flaws.

I particularly love the game’s features which add a lot of excitement while drawing attention to the players. These features also come in handy when you are looking for ways to boost your winnings.
