Release the Kraken Slot — Quick Overview

- Provider: A well established slot studio (details vary by casino)
- Reels and Paylines: Typically a 5‑reel layout with multiple ways to win depending on the variant
- RTP: Around 96 percent (see full notes below)
- Volatility: Medium to high — expect fewer frequent small wins but the potential for larger payouts

How the Game Plays
At its core Release the Kraken uses familiar slot mechanics but spices them up with interactive bonus layers. The game board may include standard playing card symbols for lower payouts and thematic icons such as buoys, anchors and deep‑sea treasures for higher value combinations. The Kraken symbol itself typically acts as a wild or special feature trigger.
Spins are executed with a single button and there is usually an autoplay option for players who prefer a hands‑off session. Bet adjustments are simple, allowing you to change your coin size and number of coins per line or select a total stake. A paytable is available in‑game and details symbol values, winning combinations and specific rules for the bonus features.
Coins, Lines and Autoplay
The flexible betting system means both penny players and higher stake players can find a comfortable setting. Autoplay lets you set a fixed number of automatic spins and safety rules such as stop on big win or stop on losing a set amount, which helps with bankroll management.
Features and Bonus Rounds
Release the Kraken features a compact suite of bonuses designed to keep gameplay lively. Below we break down the most common mechanics you will encounter and how they influence winning potential.
Kraken Wilds
The Kraken symbol often functions as a wild, substituting for other icons to complete winning lines. In some versions, Kraken Wilds may expand to cover an entire reel or lock in place for a respin, increasing the chance of a larger payout.
Free Spins
Free spins are commonly the main route to larger wins. They can be triggered by scatter symbols or by collecting a specific number of tokens during base game play. Free spin rounds frequently include extra features such as sticky wilds, increasing multipliers or additional free spins on retrigger.
Respins and Locking Mechanisms
Some variants offer a respin mechanic where landing a Kraken or special symbol locks certain reels and grants respins. These locked reels can stack wilds or improved symbols, turning an ordinary spin into a high‑value sequence.
Multipliers
Multipliers, whether permanent for the duration of free spins or temporary for a single win, are a common feature. They can significantly amplify a payout when combined with high‑value symbols or full‑reel wilds.
Bonus Buy
Depending on the casino and regulatory environment the game is served in, there may be a bonus buy option that lets you purchase direct access to the free spins feature. This can offer immediate entry to high‑variance play but usually increases risk and should be used sparingly.
RTP and Volatility
Return to Player (RTP) and volatility are two critical metrics for any slot. For Release the Kraken, expect an RTP around 96 percent. This is broadly in line with industry averages and gives a fair theoretical return over long play sessions. Volatility is medium to high, meaning that while wins may be less frequent than in low‑variance slots, bonus rounds and special features offer the potential for sizeable payouts.
It is always worth checking the specific RTP that a casino offers for the game because certain platforms provide variant RTPs (for example 94, 96 or 97 percent) as part of their configuration. RTP is a long‑term theoretical figure and will not predict short sessions; consider your bankroll and play style when choosing bet sizes.
Graphics, Theme and Sound
Release the Kraken leans into atmospheric design. Expect deep blue palettes, seabed backdrops and detailed symbol artwork that enhances immersion. The Kraken itself is presented with moody animations, tentacles that curl across the reels and dramatic sound cues at key moments like hitting a wild or triggering a bonus round.
Sound design is a key strength, with swelling orchestral hits, bubbling water effects and tension building as the bonus features approach. The theme is cohesive and will appeal to players who enjoy cinematic slots rather than purely minimalist video slots.
Mobile Compatibility
Designed with modern HTML5 technology, the slot functions smoothly on both desktop and mobile devices. Layouts adapt to portrait and landscape orientations so you can play comfortably on phones and tablets. Mobile performance is usually excellent with preserved animations and feature sets, although very old devices may experience slower animations.
Bonuses and How They Work with This Slot
Playing Release the Kraken on a UK casino often means you can take advantage of a range of bonuses. Below are the typical offers and how they interact with slot play.
Welcome Bonus and Free Spins
New players can often claim a welcome package that includes deposit match bonuses and free spins. Casinos frequently allocate free spins to be played on selected slots, and Release the Kraken may be on this list if it is a promoted title.
Remember that free spins and bonus credits come with wagering requirements. These requirements state how many times you must wager the bonus amount before withdrawal is permitted. For example, a 30x wagering requirement means a bonus of 10 must be wagered 300 before cashing out.
Reload Bonuses
Ongoing promotions like reload bonuses, weekend specials and slot tournaments are common. These offer a good way to extend play on Release the Kraken and increase your chances of hitting a bonus round.
VIP Programmes
Many casinos run loyalty or VIP programmes that reward frequent players with cashback, exclusive spins and faster withdrawals. Higher loyalty tiers may offer personalised offers that apply directly to the slots you play most.

Wagering requirements are conditions set by casinos that dictate how often bonus money must be staked before withdrawal.

Always read the full terms and check whether slot contributions are 100 percent towards playthrough, as sometimes table games contribute differently.

Practical checks to run for Release the Kraken
Before you deposit or use a bonus on Release the Kraken, run a small set of fact checks that focus on the specific game listing and the operator offering it. Don’t rely on general statements: confirm items for the exact casino and game instance you intend to use.
- Verify the operator licence: look up the casino on the UK Gambling Commission public register. Being hosted by a site that is outside GAMSTOP or carrying a foreign licence does not mean that operator is authorised by the UKGC.
- Confirm the in‑game RTP and volatility profile: many sites state an RTP for Release the Kraken (commonly around 96% in press material) but the precise figure and the volatility profile can vary by build. Check the game’s paytable or the casino’s game page for the figure that applies at that operator rather than assuming a single universal value.
- Bonus‑buy and feature variants: the original Release the Kraken title typically does not advertise a bonus‑buy option. If a site shows a ‘‘Buy Feature’’ button, treat it as a variant or casino‑specific configuration and verify via the provider’s game details before spending real money.
- Payment methods and cashout rules: if you plan to use PayPal or a debit card, read the casino’s deposit and withdrawal rules. Casinos will explain processing times, permissible withdrawal routes and whether additional ID or proof of payment may be requested.
- KYC and verification timing: licensed operators may carry out identity verification (KYC) at account opening, before gambling, or when processing withdrawals. Don’t assume checks only happen for ‘‘large’’ withdrawals — each operator’s timing can differ and should be clear in their T&Cs.
Topic‑specific checks and limitations
These checks are specific to Release the Kraken and the common situations players encounter with this slot:
- Game variant: some casinos host a branded or updated Release the Kraken variant with different features (sticky wilds, locked reels or altered multipliers). Confirm which variant is offered and open its in‑game help to read rules for respins, sticky wilds and retriggers.
- Demo availability and paytable access: if demo play is important to you, check the casino offers a free play mode for Release the Kraken. The in‑game paytable is the authoritative source for symbol values, max win and feature mechanics; screenshots or third‑party summaries may be out of date.
- Promotional eligibility: when a welcome bonus or free spins are targeted at Release the Kraken, read the bonus terms to see whether slot contributions are 100% to wagering requirements and whether free spins are restricted to a particular game variant.
- Comparisons with other themed slots: if you’re comparing to other titles, note format differences. For example, The Dog House Megaways is a Megaways‑format game with distinct free‑spin mechanics; it is not a cascading reel title. See our The Dog House Megaways Slot Review — Features, RTP & Free Play and John Hunter and the Tomb of the Scarab Queen Slot Review — Features, RTP & Free Play for other slot structures and feature approaches.
When to avoid an operator
Use these red flags to decide whether it’s sensible to move on from a casino offering Release the Kraken.
- Operator not listed on the UKGC public register, or the register entry lacks clear ownership/contact details. If you cannot confirm the operator’s regulatory status, treat the site with caution.
- Opaque game information or missing paytable for the listed Release the Kraken variant. If you cannot find the RTP, paytable or description of how the bonus features work, that’s a sign to pause.
- Poorly documented T&Cs for bonuses that require you to accept unusual wagering rules, or unclear contribution rates for slots. Always check the wagering contributions before using a promotion on Release the Kraken.
- Unresponsive or unhelpful customer support when you ask specific questions about the game variant, withdrawals or KYC requirements. Test live chat or email with precise queries before depositing.
- No named Alternative Dispute Resolution (ADR) provider in the complaints procedure. If you need to complain, the route should be: operator complaint → named ADR in the operator’s terms (for example IBAS or another approved ADR) → independent advice if the ADR outcome does not resolve the matter. The UK Gambling Commission does not adjudicate individual commercial disputes; for unresolved matters seek independent legal advice or contact Citizens Advice.

Frequently asked questions
How can I confirm the RTP and feature set of the Release the Kraken game at a particular casino?
Open the game and choose the in‑game help or paytable — that is the definitive source for RTP, symbol values and feature rules for the specific build on that site. If the game page lacks this information, contact customer support and ask for a direct reference. If you remain unsure, do not deposit until you can confirm the details.
What identity checks might a UK‑licensed casino run and when will they happen?
Licensed casinos may verify identity at account opening, before gambling, or when processing withdrawals. Typical documents requested are ID and proof of address; some operators also request proof of payment. Check the operator’s terms for its KYC policy rather than assuming checks only occur for large withdrawals.
What is the correct escalation path for complaints about a casino?
First raise the issue with the operator and follow their complaints procedure. If the response is unsatisfactory, escalate to the named ADR stated in the operator’s terms. Bear in mind the UKGC does not rule on individual commercial disputes; for unresolved issues consider independent legal advice or Citizens Advice for further options.
