Read the full review below or try the demo first to understand how the mechanics work before playing for real money.
Theme, Graphics and Sound
Release the Kraken uses a bright deep-sea setting with cartoon-style marine symbols, shipwreck details, treasure chests, and the giant Kraken as the main attraction. The visual style is polished and easy to read, with enough movement to make the screen feel active without becoming overloaded. The soundtrack has a pirate-adventure tone, supported by splashy effects and dramatic sounds when wilds or bonus symbols appear. The theme is familiar rather than highly original, but it fits the mechanics well and gives the slot a clear identity.

How to Play Release the Kraken
To play Release the Kraken game, choose your stake from the bet menu and press the spin button. The game uses 5 reels and 4 rows in the base game, with 20 fixed paylines. Wins are formed from left to right when matching symbols land on active paylines, starting from the leftmost reel.
The base game is simple at first glance, but random modifiers can appear without a classic Free Spins trigger. This means a normal spin can suddenly turn into a feature event with extra wilds, expanding symbols, or a choice-based bonus. That gives the slot more movement than a standard 20-line game.
During regular spins, you are mainly looking for high-paying sea creatures, wilds, and bonus symbols. The Bubble Wild can substitute for regular paying symbols, while special Kraken features can add larger wild structures or lock wilds in place.
The Free Spins round changes the game pace. The number of paylines increases from 20 to 40, and the Roaming Wild mechanic becomes the main feature. Wilds can move across the reels and increase the multiplier, so the bonus round has more payout potential than the base game.
In our view, the slot is easy enough for new players to understand, but the random features make it more varied than many classic fixed-payline games. The best approach is to check the in-game paytable before spinning, because some settings may vary by casino version.
Symbols and Payouts
Release the Kraken uses themed ocean symbols along with classic card symbols. Exact payouts depend on the number of matching symbols and should be checked in the in-game paytable.
| Symbol | Type | Role in the Game |
|---|---|---|
| Premium sea symbol | High-paying | One of the strongest regular symbols in the game |
| Shark | High-paying | Premium sea creature symbol with higher payout value |
| Turtle | Medium-paying | Mid-tier themed symbol |
| Blue fish | Medium-paying | Regular paying symbol with moderate value |
| Green / yellow fish | Medium-paying | Lower themed symbol used in regular combinations |
| A, K, Q, J | Low-paying | Standard card symbols with smaller payouts |
| Bubble Wild | Special | Substitutes for regular symbols to help form wins |
| Chest Bonus Symbol | Special | Triggers the Sunken Treasure bonus when the required condition is met |
| Free Spins Symbol | Special | Triggers the Roaming Wild Free Spins round when enough symbols land |
The strongest payouts usually come when wilds connect with premium symbols, especially during feature rounds where more paylines, locking wilds, or multipliers can appear.
Release the Kraken Features
The main appeal of Release the Kraken slot game is its feature variety. Instead of relying only on a standard Free Spins trigger, the game includes random base-game modifiers, wild mechanics, and a pick-style treasure bonus.
Wild Symbol
The Bubble Wild substitutes for most regular paying symbols and can help complete winning lines. It does not replace every special symbol, but it is still one of the most useful symbols in the base game. Wilds matter more when they connect with premium symbols, because those combinations create stronger line wins.
Colossal Wilds
Colossal Wilds can place a large wild symbol on the grid, covering multiple positions at once. This feature can quickly improve the chance of building several winning paylines on the same spin, especially when the wild lands on central reels with matching symbols around it.
Infectious Wilds
The Infectious Wild feature can turn nearby symbols into wilds. This gives the base game a more dynamic feel because a single wild event may improve several reel positions at once. It does not guarantee a big win, but it can turn an ordinary-looking spin into something more useful.
Kraken Locking Wilds
Kraken Locking Wilds can add wilds to the reels and keep them locked for part of the feature sequence. This is one of the more interactive mechanics in Release the Kraken slots, because it can build stronger win potential over multiple steps rather than relying on a single symbol drop.

Sunken Treasure Bonus
The Sunken Treasure Bonus is a pick-style feature based around treasure chests. You select chests to reveal prizes, and the round continues until a collect symbol ends the feature.
This bonus fits the theme well and gives the slot a different rhythm from the reel-based features. Players who like instant pick bonuses may find this one of the most enjoyable parts of the game.
Roaming Wild Free Spins
The Roaming Wild Free Spins round is the main bonus feature in Release the Kraken pragmatic play. During this round, the game uses 40 paylines instead of 20, and roaming wilds can move across the reels. The multiplier can increase when wilds appear, which creates the slot’s strongest payout potential.
This feature is the reason many players try the Release the Kraken demo before real-money play. It shows how the slot behaves when wilds, extra paylines, and multipliers work together. The bonus can still be unpredictable, but it is clearly the most important part of the game.
Bonus Buy
Some casino versions may include a Bonus Buy option, allowing players to purchase access to a feature instead of waiting for it to trigger naturally. The price and availability depend on the casino and local market rules.
Bonus Buy can speed up gameplay, but it also increases risk because the purchased round does not guarantee profit. We would only use it after testing the Release the Kraken free play mode and understanding how volatile the bonus can feel.
RTP, Volatility and Max Win
The default Release the Kraken rtp is 96.50%, although some casinos may use lower RTP versions such as 95.50% or 94.50%. That is why it is worth checking the game information screen before playing at a Release the Kraken online casino.
RTP is a long-term theoretical figure and does not guarantee results in a single session. It simply describes the expected return across a very large number of spins, not what will happen to your balance today.
Release the Kraken is usually described as a medium-high to high-volatility slot, depending on the casino or review source. In practical terms, this means the base game can have quiet stretches, while stronger wins are more likely to depend on wild features, Free Spins, and multipliers. The maximum win is 10,000x the bet, which gives the game serious top-end potential, but that result is rare.
We would describe the pacing as feature-driven. Small line wins can appear often enough to keep the reels moving, but the most memorable moments usually come from Kraken wilds, treasure bonuses, or the Free Spins round.
Release the Kraken Free Play
You can use Release the Kraken free play mode to test the game without making a real-money deposit. The Release the Kraken slot demo uses virtual credits, so there is no financial risk, and any demo winnings cannot be withdrawn.
Demo mode is useful because it shows how the random modifiers, Sunken Treasure feature, and Roaming Wild Free Spins work in practice. It is also a good way to judge whether the volatility feels comfortable before switching to Release the Kraken real money play.
Mobile Experience
Release the Kraken online works well in mobile browsers on iOS and Android, so no separate slot app is usually required. The buttons are touch-friendly, and the bet menu, spin button, autoplay options, and paytable are easy to access on smaller screens.
The game’s cartoon visuals scale clearly on mobile, and the reel layout remains readable in portrait mode. Landscape mode may feel more comfortable for feature animations, but the slot is fully playable either way.
Pros and Cons
Here are the main strengths and weaknesses to consider before you play Release the Kraken.

Our Verdict
We would recommend Release the Kraken game to players who like underwater adventure slots with wild modifiers, pick bonuses, and Free Spins that carry real top-end potential. It may not suit players who prefer frequent small wins or very simple classic slot machines, but the demo is worth trying if you enjoy feature-led Pragmatic Play games.
The main reason to try this Pragmatic Play slot is the Roaming Wild Free Spins round, supported by random base-game modifiers that keep regular spins from feeling too flat. Remember that slot results are random, and no strategy, timing method, or betting pattern can guarantee a win. Play for entertainment, set limits, and avoid chasing losses.
