The Kraken is a big, bad, and many armed undersea monster. The stuff of legend, and of plenty a bad special-effects old movie! It’s probably some sort of version of a giant squid that grew in size and monstrosity in the telling of tall tales by sailors.
Here it’s a bit friendlier, given a nice cartoon makeover by Pragmatic Play, and dumped onto the top of the pay table that might have some very good news for players because this is a big-paying machine – if you hit lucky.
There are multiple bonuses in this complex video slot released in January 2020, and it’s one of a series from Pragmatic Play that mixes high volatility with genuinely big prizes.
This Release the Kraken slot game has a great, original theme, but should you brave the deeps in the hope of lifting up your balance with a jackpot win from this Kraken?
Let’s have a look.

Where problems arise
The UKGC records a 30 June 2026 settlement with Betfred operator Petfre (Gibraltar) Limited: a £900,000 payment for failings in remote customer-interaction controls identified through a 2024 assessment. A separate 2025 technical-standards case brought a £240,000 penalty; the regulator noted self-reporting, immediate remedial action and cooperation in that case. These are operator-level findings, not evidence that a particular customer withdrawal remains unpaid.
This feedback summary draws on Trustpilot, Casinomeister, OLBG and app-store feedback, alongside a Reddit contributor's account.
Games players come back for
The strongest praise is for familiar games and an easy-to-follow layout. A September reviewer enjoyed the recognisable slots and choice of live dealers, while an App Store player found the app straightforward to navigate. On Casinomeister, a Bristol member named Betfred among their favourites in 2025. A Reddit player also describes withdrawing after a slot session.
When the app gets in the way
Recent Trustpilot casino reviews are more critical, covering unanswered messages and trouble getting help. A September 2026 Google Play reviewer says the app repeatedly failed to open, leaving them unable to play or withdraw winnings despite contacting support. An earlier App Store account also mentions crashes and slow withdrawal checks.
What happened after a complaint
In October 2024, one Casinomeister player said Betfred released their funds after telephone escalation and documents explaining a deposit made with a friend's card. That was a specific third-party payment dispute. A separate February 2026 thread concerns lost Extra Chilli progress following an update; the final posts do not establish a resolution. Helpful outcomes are possible, but the accounts also show how much follow-up some problems require.

Quick withdrawals are a highlight for happy Genting players. They also like being able to find their favourite games without fuss. Getting account or bonus queries sorted has been less straightforward for others...
What players like
A September 2026 UK reviewer praises fast withdrawals. In another promotional exchange, the operator says it made an exception and credited the missing reward.
Where problems arise
A substantial 2025 winnings dispute is also publicly documented. Casino Guru records it as rejected after the ADR decision favoured the casino, with the case closed on 1 July 2025. The recent comments checked do not establish a general current non-payment pattern.
This feedback summary brings together Trustpilot, Casinomeister, WhichBingo and app-store feedback, alongside older AskGamblers reviews.
Easy play and quick payments
Recent Trustpilot players often describe Genting as easy to use, with enough game choice to keep them interested. In September, Clive reported a payout within minutes, while another reviewer praised both depositing and withdrawing. Others enjoyed being able to find their games and get on with playing. The older AskGamblers history also includes happy live-table players, although those accounts belong to the earlier GentingBet service.
The difference when help is needed
The more detailed accounts show where an otherwise straightforward visit can become frustrating. Players in the 21 September 2026 sample described a login loop and a game-balance investigation awaiting an answer at that time. UK App Store reviews add an unfinished-game message blocking a withdrawal and concern about money left in a closed account. Genting replied, but the players did not confirm that those problems were resolved. Three WhichBingo reviews from 2022-23 describe withdrawal waits, document requests and difficulty reaching support.
What the forum history adds
Casinomeister brings two specific older disputes into view: a missing roulette balance in 2023 and a disagreement over the calculation of a rolling loss limit in 2024. Neither thread establishes a repayment or a confirmed breach.

Helpful staff, plenty of games and reports of speedy payouts. Players also speak well of the mobile experience. Some withdrawals take longer when checks are needed...
What players like
Customers praise game choice and completed withdrawals. In one delayed-payment exchange, Pub says it processed the request following a manual check.
Where problems arise
That explanation is the operator's account, not independent confirmation of when the money arrived. We did not identify a recurring unresolved UK non-payment pattern in the material checked, but the sample is limited and includes invited reviews. It is not evidence that the casino has never had a payment problem.
This feedback summary brings together Trustpilot, Casinomeister, Casino Guru and AskGamblers.
Getting your money
Quick withdrawals are a recurring bright spot. Several Trustpilot reviewers describe payments arriving within minutes or hours, while older Casino Guru accounts mention next-day payments and two bank withdrawals within 48 hours. A Birmingham Casinomeister member added their own experience in January 2026, describing Pub payments on the next working day.
A helping hand and games to explore
Players often appreciate being able to speak to someone who explains what is happening. One Trustpilot reviewer credits an agent with escalating and sorting out a problem; a Casino Guru player describes help with verification. Game choice earns praise across the review sites, and a Casinomeister member included Pub among their favourites in 2025. Older AskGamblers reviews add positive experiences on mobile and with loading games, although one player found searching for a particular title less convenient.
Where things can feel less smooth
Extra document requests and frustrating support exchanges appear too. An October 2024 Casinomeister discussion follows one player's difficulty with verification after changing payment route. The casino representative said the account had subsequently been verified and was withdrawing; the player remained unhappy and did not independently confirm receipt.

Live chat has helped some players get problems sorted quickly. Positive reviews also mention the game selection and prompt cashouts, although account access and withdrawals attract more mixed feedback overall...
Where problems arise
UK comments from May and June 2026 describe account closure around a withdrawal or a remaining balance. Other customers report being locked out after depositing or waiting for verification guidance. The exchanges checked do not settle the final account outcomes. It would be premature to describe this as a complaint-free brand or to treat every allegation as proven non-payment.
This feedback summary draws on Trustpilot, LCB, AskGamblers and Casino Guru, including forum accounts and detailed complaint histories.
Enjoyable games and some quick help
The brighter experiences centre on game choice and getting a helpful answer when something goes wrong. One AskGamblers player describes enjoying the games and having withdrawals processed instantly, although they found some chat replies contradictory. A UK LCB contributor also enjoyed playing, but wanted support to respond more promptly. Over on Casino Guru, a player describes a problem being sorted quickly through live chat and says a fuller help section would make it easier to find answers independently.
Account access needs attention
The more worrying pattern is difficulty getting back into an account. Several UK Trustpilot posts from December 2025 describe losing access after depositing, with one player still waiting for specialist help after 48 hours. Another reviewer reports waiting several working days after sending withdrawal documents.
Following the disputes through
An AskGamblers forum contributor describes account closure and a disagreement over winnings, without a public follow-up establishing the outcome. A separate UK GAMSTOP complaint on Casino Guru was referred onward because the site could not determine the exclusion issue. Neither establishes a confirmed repayment.

What players like
A September UK reviewer describes a smooth withdrawal. In a separate fee complaint, the operator says it refunded the deduction after reviewing how support handled the case.
Where problems arise
The more serious issue is a November 2025 GAMSTOP complaint still marked unresolved by AskGamblers when checked. The customer alleges they were allowed to gamble while self-excluded. This is a published complaint, not a confirmed UKGC finding.
This feedback summary combines All British Casino accounts from Casinomeister, Trustpilot, OLBG and other player communities.
Helpful people and memorable cashouts
Friendly support is a recurring strength in recent Trustpilot feedback, with players naming the staff who helped them and praising fast payments. Casinomeister adds detail: two UK members described cashouts arriving within seconds in December 2025. One had first completed financial checks with priority help from the forum representative, so that particularly quick turnaround had extra assistance behind it.
The everyday experience
Older AskGamblers accounts include a withdrawal approved the same evening and clear help with the documents needed for verification. OLBG's player comment adds an easy start using PayPal. LCB feedback also praises the game choice, although it includes frustration with wagering and slot performance. One player described quick support replies but confusing explanations about when verification was complete.
When checks become complicated
Some older accounts describe verification difficulties. Older AskGamblers and LCB accounts describe repeated document requests and confusing explanations. In a Casinomeister discussion from April 2025, a player confirmed payment the next morning after bank checks, while remaining unhappy with the process. A separate June 2026 complaint concerned using a partner's Apple Pay account; the representative offered to investigate, but the thread has no confirmed outcome.

Pragmatic Play - The Developers of Release the Kraken Slot
Pragmatic Play are a well-established and trusted slot developer with some massive hits in the UK regulated casino market.
Their biggest current titles are the twin Gold games, linking iconic big wild animals with old west style and an excellent prize bonus game.
Wolf Gold is the number five title in the UK at the moment and Mustang Gold isn’t far behind.
Chilli Heat, Aztec Bonanza, and John Hunter and the Tomb of the Scarab Queen complete the company’s top five, all in the top 50 UK titles.
That’s a great performance, so you can see why they’re seventh most popular UK slots provider.
They have a lot of titles, 220 at the last count, so they cover every base in terms of style and genre. That makes it hard to tie them down to a particular style, but they are well known for high volatility games with big top prizes.
A bit like Release the Kraken slot!
The Facts and Figures
To start at the top: 10,000-times stake is an excellent top prize.
That also comes with what looks like a very generous looking RTP of 96.5%. This comes with a bit of a warning though: this is an indicative figure from Pragmatic Play, and casino sites are at liberty to change RTP on the site, so check with the game you’re playing to be sure of the RTP. (It’s always a good idea to check the rules, regs, limits and laws on the actual game you’re playing when you play it – just in case.)
It’s a medium to high variance game, which means it is probably best suited to riskier players. Volatility is calculated by ranking the frequency of pay outs with the size of prize – frequent low prizes = low volatility.
The game has a five-reel, four-row grid, which makes the 20 pay lines across the playing surface a somewhat low number.
That 10,000-times prize will be paid out on bets running from 0.2 to 100 coins, usually 20p to £100.
Play this game on any device that supports JavaScript and HTML5.
The Game
This is a complex game, but it’s very easy to play, and any online slots player will soon feel at home here.
The information, sound, and menu buttons cluster together on the right of the control panel, then, reading across from left to right we find: the credit balance and bet amount; the information and win window; the right of the screen is the spin control, surrounded by Autoplay, and the Bet controls.
It’s a very standard set-up delivered with elegant design.
Payouts
Click to open up the pay-table and this is what you should see.
The card symbols pay from double to a four-times stake for a full house.
The green and yellow fish pay out five-times stake for a full house.
The blue Fish pays 7.5-times stake for a full house.
The turtle pays 10-times stake for a full house.
The shark pays out 12.5-times stake for a full house.
The anchor game logo pays 25-times stake for a full house, and this figure is matched by the wild, a bubble.
Release the Kraken Slot Bonuses
From the base game, a random bonus can be triggered via the Kraken.
He – I assume it’s male – drapes three tentacles across the screen, from which players pick one for:
Kraken Lockin – a random pick prize game with extra wilds, a loss, or 2-times multiplier.
A Colossal Kraken puts a giant Kraken wild on the screen.
The Infectious Kraken puts a wild that converts neighbouring symbols to wilds.
If the bonus symbol appears on reels 1 and 3 alongside a chest symbol on reel 5 you get another prize pick game with cash prizes continuing until you pick a miss.
The bonus is a scatter and triggers via the bonus symbol and the free spins symbol, on reel five. A chest pick decides how many you will get. The reels get 20 more pay lines and an increasing multiplier climbs up by 1 (from 1) for every wild that is hit. Wilds stick on the reels once they land.
The Verdict
What’s the big boundary number in slots?
To us, it’s £1 million. And Release the Kraken slot is a £1 million game.
That’s a big big big outside bet, but there’s something magical knowing you could win that amount of money in a single spin.
The Kraken is more than that though, it’s a great quality slot game from the moment you dive in. The look and feel are fun – with something of Finding Nemo (like almost all underwater games) about the graphics – and the sound adds to the atmospherics effectively.
This Release the Kraken slot game has more depth than the Mariana Trench, with bonus games at every stage of the game, and a lot of choices to make that keep the player engaged.
Don’t be afraid of this Kraken, dive in and join in the fun!
