Key Game Features

With the help of the Release the Kraken 2 online slot, every player is taken on an underwater adventure. They will meet various marine animals and specific plants and find hidden treasures there.

Users can expect the well-known playing card icons as low-paying basic symbols on the paytable (from 10 to Ace). In addition, they can expect four more basic symbols represented by an Eel, an Anglerfish, a Pufferfish, and a Shark. The difference between the lowest and highest paying symbol here is relatively high. The Shark can provide ten times more than the 10, Jack, and Queen (up to 10 times the player’s stake).


Like most online slots today, this game has 5 reels. Players can hit winning combinations by landing three to five matching basic symbols on a single payline from the leftmost reel to the right reel. The top-paying icon, the Shark, also provides payouts for 2 identical symbols on a payline.


There’s nothing new in the reels department of this online slot. So, you’re looking at a game with 20 fixed reels which is more or less a standard number in modern titles. It’s not uncommon to cover paylines entirely with a single icon which is great.


All Pragmatic Play slots have a default Return to Player (RTP) percentage. But this doesn’t mean you can expect identical RTPs in all online casinos. Ultimately, it’s their right to adjust the rate up to a certain level, of course.

Of course, the Release the Kraken 2 slot is not an exception. So, this slot’s default RTP set by the provider is 96.50%. To find the best RTP for this release, we created a list displayed below. 

Remember that it’s not just the RTP that might affect your gameplay. For example, some websites have excellent casino welcome offers and bonuses. You should take these things into account before deciding.

Stake Range

Every player can place stakes as low as £0.20 and as high as £100 per round. Simply put, both low and high bets are accepted in this game.

Max Win

We’ve tested many online slots, and we can say freely that the max win cap in this release is pretty decent. To be more precise, you can expect a maximum win of 5,000x your bet.

Of course, you will need a lot of luck to achieve this goal, but you never know because slots are a game of chance.

Scatter/Free Spins

If you are a fan of free spins, the Release the Kraken 2 slot will not disappoint you. This feature is triggered whenever you get three or more bonus icons. They might be called bonus icons here, but they act like classic scatter icons and are represented by a golden Octopus plate.

The number of participating scatters impacts the number of free spins you can get. Don’t forget that you can play a mini-game to win a combo of free spins and a win multiplier for the next round. So, the number of bonus scatters you’ve hit, and the mini-game can provide various combinations.

  • 3 Bonus/Scatters – 4 to 15 free spins with 1x to 6x multiplier
  • 4 Bonus/Scatters – 5 to 20 free spins with 1x to 10x multiplier
  • 5 Bonus/Scatters – 6 to 20 free spins with 1x to 10x multiplier

The abovementioned bonus game lets you choose from 16 boxes with specific combos. It’s up to you to accept the outcome or ask for another chance to pick new boxes. We should also note that during free spins, there are 40 active paylines and the Wilds act like Moving Sticky Wilds. In other words, they will stay on the matrix until the end of the round but move to random positions.

Landing a Golden Wild will boost the multiplier for the current spin by 1x. Players can’t re-trigger this round.

Random Features

Randomly, on any spin, the slot can activate one of the three bonus features:

Wild Respin

In case you get at least four Wilds, once you get paid, you’ll also receive a free respin round. So, the Wilds will stay on the layout and move to random positions while the other icons respin. Landing at least one new Wild will provide an additional respin.

Shifting Stacked Wilds

The elongated Octopus is a Shifting Stacked Wild icon that shows up on the central three reels. They appear as regular Wilds but cover the entire reel once the reels stop spinning. For every position moved, the multiplier increases by 1x for each special wild present on the matrix.

Guaranteed Win

At random, after any non-winning spin, the Kraken can appear on the screen and replace some of the symbols so players can get a winning combination worth 20 to 60 times their bet. It’s also possible for the Kraken to activate a round of free spins.


There’s no direct jackpot in this online slot game. Those looking for jackpots should visit our page dedicated to the best jackpot slot games.

Play Experience & First Impressions

Even though the winning combos will not appear on the screen every second spin, this slot gives you a decent chance to win solid prizes. The free spins mode makes this scenario even more realistic.

Remember that you’re looking at a high-volatility title with an above-average RTP.

100 Spins

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Session RTP101.22%
Win FrequencyMedium
Biggest Base Game Win39x
Spins to Bonus23
Bonus Paid85.7x
Time Taken for 100 Spins5:05

Being a pragmatic play new release, hitting the bonus in 23 spins was somewhat of a surprise, i rarely expect ti hit PP bonuses, with this limited 100 spin test - 

In any case, hit it did, in just 23 spins, providing a nice 85.7x bonus with a good number of stacked wilds, hitting the Kraken in one good spin.

Outside of the bonus, the action was OK, wins were small but frequent, and as is likely with most pragmatic play games, good base games wins are a part of the experience, on this occasion, and nice 39x hit on normal spins.

The 100 spins including the bonus too only just over 5 minutes, so bear this in mins, it can be a credit muncher.

Thanks to the base hit and the bonus, I came away 1.2% up, with a 101.22% RTP for the 100 Spin session

Expert Verdict

The random features are among the best things about the Release the Kraken 2 slot. You never know when the Kraken will appear and grant you a guaranteed win, a moving wild, or even a wild respin. This adds to the thrill. I also like the opportunity to boost the free spin round with extra spins and higher multipliers, thanks to the mini-game.

The wins might not be that frequent, but from my experience, activating one of the bonuses should take a lot of time. The only potential downside is the relatively low payouts achieved with the help of the basic symbols. Other than that, I think that Pragmatic Play did an excellent job.
