Welcome to Release the Kraken Online Slot

Release the Kraken drops you straight to the ocean floor with a 5x4 layout and 20 fixed paylines in the base game. Bets range from 0.20 up to 100 per spin, which suits both cautious players and those who like to push the limits. As someone who has spent a fair bit of time with Pragmatic Play titles, the mix of random modifiers, pick bonuses, and free spins stood out straight away.

On paper, Release the Kraken is a high volatility slot with a theoretical max win of 10,000x your bet, so the maths has some bite behind the cartoon visuals. The game uses a standard left‑to‑right payline system, but the features shake things up often enough that the base game rarely feels static. When the tentacles first slapped across my screen and the chest picks started, I realised this slot was not short on action.

Mythical Beast Theme and Cartoonish Graphics in Release the Kraken

The theme leans on the legendary sea monster from Norse and Scandinavian tales, but Release the Kraken keeps things light. The reels sit over a sunken ship on the seabed, framed by coral and swaying plants, while the Kraken lurks off‑screen until the features kick in. The visuals have a bright cartoon style, yet the soundtrack is far more cinematic, building a sense of lurking danger whenever the beast decides to stir.

Symbol wise, the high pay icons are the game logo or anchor, a shark, a turtle, a blue fish, and a green and yellow fish. Five of a kind with these pay between 5x and 25x your bet, with the shark at 12.5x, turtle at 10x, blue fish at 7.5x, and the smaller fish at 5x. Card royals from J to A handle the low pays, worth 2x to 4x for five‑of‑a‑kind wins.

The regular wild is a bubble that can substitute for anything except the bonus symbols, which include the ship scatter, a helm for free spins, and a chest symbol for the Sunken Treasure feature. During my sessions, the special Kraken wilds in the random features really lifted the screen presence, with Colossal and Infectious wilds dominating whole sections of the grid. When several wilds, a shark, and the logo line up, you can feel the potential in the paytable.

How to Play Release the Kraken Slot Online

Getting started with Release the Kraken is straightforward. Set your stake with the plus and minus buttons until you are happy somewhere between 0.20 and 100, then hit the spin button or turn on autoplay. Wins land when three or more matching symbols hit adjacent reels from the left on one of the 20 paylines. In the free spins feature, the layout keeps the 5x4 shape but expands to 40 paylines, which changes the way line hits fall.

Breathtaking Bonus Features in Release the Kraken

Release the Kraken is packed with features, and the first set arrives as random modifiers in the base game. At any spin, three tentacles can appear, each holding a sign, and you pick one to trigger Kraken Lockin Wilds, Colossal Kraken Wilds, or Infectious Kraken Wilds. Kraken Lockin uses chest picks to add wilds, keep the reels spinning, or apply a 2x win and end the feature, while Colossal and Infectious versions plant large or spreading wilds on the grid.

Beyond that, there is the Sunken Treasure Bonus, triggered by ship symbols on reels one and three plus a chest on reel five. Here you keep picking from three chests for cash prizes until you hit collect. The headline act is Roaming Kraken Free Spins, activated with ships on reels one and three and a free spins symbol on reel five. You pick chests for batches of one to three spins up to a cap of 12, then play with 40 paylines, sticky roaming wilds, and a multiplier that climbs by one for each wild that lands. If you are impatient, there is also a buy feature that triggers free spins for 100x your stake.

RTP, Variance, and Max Win in Release the Kraken

The theoretical RTP for Release the Kraken is usually quoted around 96.5%, with some descriptions giving a figure of 96.55% and others 95.5%, so I always check the info screen in the version I play. The volatility is high, rated roughly four out of five, and that matches my experience: long quiet stretches punctuated by sudden swings when the modifiers and free spins line up. With a maximum win potential of 10,000x your bet, the game can hit hard when everything comes together.

Is the Release the Kraken Slot Machine Worth it?

From a regular player’s point of view, Release the Kraken has plenty going for it. The random tentacle features keep the base game lively, the Sunken Treasure picks throw in steady cash pops, and the Roaming Kraken Free Spins round can go wild once several sticky roaming wilds are walking across 40 lines with a growing multiplier. In one extended session I triggered the free spins twice; neither run hit the advertised heights, but both showed clear potential.

The flip side is the volatility. Sessions can burn through a balance when the tentacles refuse to appear or when Colossal wilds land in poor spots, and paying 100x for a bonus buy is not something I do lightly. If you enjoy high‑risk slots with strong feature variety, Release the Kraken is well worth a spin. If you prefer smooth, low‑variance play, I would treat it as a short, feature‑hunting excursion rather than a long grind.
