Release the Kraken

Considered among the leading content providers in operation, Pragmatic Play is responsible for the some of the best-loved online casino games ever produced. The developers can now add another hit to their growing collection with this eye-catching, maritime-themed slot.

Join us as we embark on a daring underwater voyage to uncover hidden treasures guarded by a legendary sea beast via a 5-row, 4-reel setup.

Release the Kraken comes jam-packed with features, highlighted by three bonus games and bucket-loads of free spins that make for a wild, action-packed sea adventure.

Popularised by Moby Dick and 20 Leagues Under the Sea, the game’s central character is a cephalopod known as the Kraken, who holds the key to unlocking rewards worth up to 10,000x your stake.


The game takes place upon the seabed, revealing an abandoned shipwreck that presumably met a ghastly end courtesy of the fearsome Kraken.

In the graphics department, this slot looks the business, with imagery rendered in sharp 3D graphics that make use of vivid, maritime shades. Turn up the volume to take in haunting sound that effects accompany us in our hunt for Sunken Treasure, ramping up the fear factor.

Expect to find low-paying symbols like token playing card icons from J-A, in addition to four different coloured fish that constitute the game’s more lucrative symbols. Keep an eye out for the game’s logo symbol, which rewards you with a 500x bet multiplier when filling an entire payline.


Release the Kraken boasts an impressive array of bonuses for you to feast your tentacles on, but the main aim is to line up at least 3 matching symbols across any of the 20 paylines to score a win.

Playing cards return up to 80x your stake, while the nemo-like fish come with higher rewards worth a max. 200x. Land a win with 3 matching sharks to get up to 250x your bet.

The game’s Wild is represented by the Bubble, which substitutes all other symbols when forming part of a winning combo.

At any point during the game you could see three tentacles show up on the reels, clutching a sign that reads “Pick Me”.

You’re then prompted to select from one of the three options available in order to trigger a special bonus round, which we’ll explain in further detail below.

Kraken Lockin Wild

New Wilds come into play whenever this option is chosen, and your job is to open all three chests that are suddenly presented before you, each possessing a different type of reward.

Additional Kraken Wilds fill the reels when you trigger the ‘More Wilds’ bonus, while ‘All Wins x2 and Collect’ ends the feature - but only after multiplying any winnings. ‘Continue Spinning’ is not worth much, and seeing ‘Collect’ will terminate the feature and credit winnings back to your bankroll.

Colossal Kraken Wilds

A life-size Wild joins the game whenever Colossal Kraken Wilds is activated, which can cover any number of positions across the grid.

Infectious Kraken Wilds

Make use of one additional Infection Kraken Wild after triggering this bonus, and watch as existing Wilds transform all symbols in adjacent slots into Wilds too.

Roaming Kraken Free Spins

If all this bonus action is not enough for one slot, the game also throws in another exciting feature: Roaming Kraken Free Spins.

Land Bonus Symbols across the first and third reel, plus a further Free Spins symbol across row #5 to set off this round.

You’ll then notice your screen become filled with a selection of chests, each offering between 1 and 3 free spins. Continue opening each box until you find the dreaded ‘Collect’ message that terminates the feature and prepares to run your accumulated free spins.

Ramping up your win potential further, Free Spins rounds benefit from double the number of paylines on offer vs. the base game, and come with multipliers that increase on every new Wild appearing.

Release the Kraken Mobile

Release the Kraken is fully optimized for mobile play, providing players with a smooth gaming experience on just about any modern device - be it iOS or Android. The mobile version also benefits from the same stunning visual quality as desktop, letting you dive in and fire up this slot whenever and wherever.

High Volatility

Release the Kraken is certainly not for the faint-hearted, and represents a better fit for those willing to ride long, fruitless sessions in the hunt for a big score. With a limited supply of top-end rewards, the game ranks high in the volatility stakes.

The Verdict

Beautifully crafted, Release the Kraken cleverly plays on the central maritime theme, inviting you down to the deep blue sea for a high-octane adventure that does not disappoint.

Players can take advantage of a limitless supply of bonus features that span the depths of the ocean, boasting a huge amount of multiplying Wilds that are enough to make you dizzy.

Fans of another Pragmatic Play hit, Hercules and Pegasus, will find lots to enjoy here, with similar bonus mechanics in play that also provide the lure of a monster payday.

With a high volatile rating, however, the slot won’t please everyone. Those more at ease with a steady stream of smaller wins are advised to take their slot action to other top titles at Caxino.

Overall this is a super exciting game, throwing up hours of endless fun from one of the industry’s heavyweight game suppliers.
